why would a pregnant mother need more calcium than a woman her age that is not pregnant?​

Answers

Besides building teeth and bones, calcium also keeps your blood and muscles moving and helps your nerves send messages from your brain to the rest of your body. Your body can't make calcium, so you need to get it from food or supplements. While you're pregnant, try to get at least 1,000 mg of calcium every day.

Calcium is a vital mineral. Your body uses it to build strong bones and teeth. calcium is also needed for your heart and other muscles to function properly

Identify the error in this statement: “If a reaction transfers energy to the surroundings the product molecules must have more energy than the reactants”

Answers

Answer:

See explanation

Explanation:

A reaction may be exothermic or endothermic. In an exothermic reaction, energy is given out from the reaction system. This means that energy is transferred to the surroundings and the reactants have more energy than the products.

A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. In this case, the products have more energy than the reactants.

So the statement "If a reaction transfers energy to the surroundings the product molecules must have more energy than the reactants” is erroneous. The error in the statement is the part that says "...the product molecules must have more energy than the reactants”. It ought to have read, "the reactants have more energy than the products" in accordance with the explanation above.

Which of these best represents the location of the Earth’s core?

A
the pit of a peach

B
the crust of an apple pie

C
the bread in a peanut butter and jelly sandwich

D
the white of an egg

Answers

The best answer would be A) The pit of a peach. The Earth’s core is the center ball of the earth essentially, therefore it is like the pit of a peach. All the other answers don’t make sense because they surround something, they aren’t the center of it. For example, if D said the “yolk” of the egg then it could be considered a correct answer because it would be the center of the egg, just like the core is in the Earth. The center of the Earth is the core!

Hope this helps!!
- Kay :)

The  best represents the location of the Earth’s core is the pit of a peach. Therefore, option A is correct.

What is earth's core ?

The earth core is almost entirely composed of metal, notably iron and nickel, in contrast to the crust and mantle, which are rich in minerals. Iron-nickel alloys found in the core are denoted by their chemical symbols, Ni,Fe. The core also contains siderophile, or substances that dissolve in iron.

The Earth's inner core contains even more metal than the outer core. Both are primarily comprised of iron with a small amount of nickel. However, lighter elements like oxygen, carbon, and silicon are also assumed to be present in small amounts in the iron.

This inner core is around 5,400 degrees Celsius hotter than the Sun's surface. The remaining portion is the liquid outer core of the Earth, which is primarily composed of nickel and iron and has temperatures that are similar to surface temperatures before becoming hotter toward the center.

Thus, option A is correct.

Answers

A rumor spread faster in a classroom where students are confined to desks than in a gym where all of the students can move around freely.

The same applies to conductivity between metals and ionic solids because metals have more close particles.

What is conductivity?

Conductivity is the process by which a material is able to transfer electric charge or heat from one point to another without the actual movement of the particles of the substance.

The conductivity of substances varies from one substance to another.

The conductivity of solids is greater than the conductivity of that of other substances.

The conductivity of substances increases with a decrease in the distance between the particles of the substance.

Thus solids that have the closest particles have the highest conductivity.

Liquids have medium conductivity.

Gases have the least conductivity because they have the most spaced-out particles.

Calculate the maximum mass of calcium chloride produced by reacting 8.02 grams of
calcium with excess hydrochloric acid.
relative atomic mass: Ca = 40.1
relative formula mass: CaCl2 = 111.1
Show your working.

Answers

Answer:

22.22 g

Explanation:

The balanced reaction equation is;

Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g)

Number of moles of calcium reacted = 8.02g/40.1g/mol = 0.2 moles of Calcium

From the reaction equation;

1 mole of Ca yields 1 mole of CaCl2

Hence 0.2 moles of Ca also yields 0.2 moles of CaCl2

Mass of calcium chloride produced = number of moles * molar mass

Mass of calcium chloride = 0.2 moles of CaCl2 * 111.1g/mol = 22.22 g

Why do waves move faster at higher temperatures and in a solid phase?

There is more energy and the particles are farther apart.
There is less energy and the particles are closer together.
There is less energy and the particles are farther apart.
There is more energy and the particles are closer together.

Answers

Answer:

Higher temperatures means more energy, and a solid phase means the particles are close together. This results in highly energized particles that bump into the particles close to them, who in turn bump into more particles.

Explanation:

waves move faster at higher temperatures and in a solid phase there is more energy and the particles are farther apart there is less energy and the particles are closer together there is less energy and the particles are farther apart there is more energy and the particles are closer together.

The waves move faster at higher temperatures and in a solid phase because there is more energy and the particles are closer together.

What is wave?

A wave can be described as a medium which transports energy without causing net particle movement. Elastic deformation, pressure change, electric along with magnetic intensity, electric potential, or temperature can all be examples.

What is energy?

The quantitative property that's also transferred to a body or a physical system, recognizable in the work performance as well as in the form of heat and light, is called energy.

What is temperature?

Temperature is the measurement of a body's degree of hotness or coolness.

The faster the wave is conveyed, the greater the particle interactions are. In general, sound travels quicker through solids than through liquids, and faster through liquids than through gas. Because warmer particles move at a higher pace, the temperature actually speeds up to sound.

Therefore, the correct answer will be option (d).

If the standard pressure in a car tire is 38 psi, what is the force exe
the tire if the area of the tire is 12 cm by 18 cm? Round your answ
pound.

Answers

Answer:

1272 pound

Explanation:

From the question given above, the following data were obtained:

Pressure (P) = 38 psi

Area (A) = 12 cm by 18 cm

Force (F) =?

Next, we shall determine the area. This can be obtained as follow:

Area (A) = 12 cm by 18 cm

A = 216 cm²

Next, we shall convert 216 cm² to square inch (in²). This can be obtained as follow:

1 cm² = 0.155 in²

Therefore,

216 cm² = 216 cm² × 0.155 in² / 1 cm

216 cm² = 33.48 in²

Finally, we shall determine the force exerted. This can be obtained as follow:

Pressure (P) = 38 psi = 38 lbf/in²

Area (A) = 33.48 in²

Force (F) =?

P = F/A

38 = F / 33.48

Cross multiply

F = 38 × 33.48

F = 1272 pound

Thus, the force exerted is 1272 pound

It becomes easier to bend because the metal is getting weaker as you bend it

Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.

What is metal ?

A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.

These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.

The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.

* i think i am right and i really hope so but please dont

count it against me babe.

explanation:

Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix.

A hydrogen bond is formed when the positive end of one molecule is attracted to the negative end of another. The concept is similar to magnetic attraction where opposite poles attract. Hydrogen has one proton and one electron. This makes hydrogen an electrically positive atom because it has a deficiency of electrons.

A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even. Some chemical species, such as chains of carbon molecules, share electrons equally and are said to be nonpolar molecules

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
