Answers

Answer:

The melting of a glacier is an example of interaction among;

Hydrosphere, asthenosphere, atmosphere

Explanation:

The melting of a glacier is an example of the interactions among the Earth's cryosphere and hydrosphere

The cryosphere is described as the portions on Earth where water appears in solid (frozen) form such as glaciers, frozen grounds, snow covered land, sea ice, ice sheets, river ice, ice caps, etc.

The hydrosphere is all the forms water on a planet including, ice, liquid water and water vapor, therefore, the cryosphere is a part of the hydrosphere

The geosphere comprises the Earth's interior, including the asthenosphere, which is fluid and hot and therefore spread heat through both conduction and convection to the hydrosphere that raises the ocean temperatures and lead to glacier melting

The green house effect in the atmosphere results in global warming that raises the average temperature of the Earth which in turn raises the temperature of the oceans and the troposphere, resulting in melting of a glacier

Therefore, the melting of a glacier is an example of interaction among the hydrosphere, asthenosphere, and, atmosphere

uz RS nyodag

Answers

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.

Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.

Answers

Answer:  The intertidal or littoral zone maintains a balance between the land and the sea. It provides a home to specially adapted marine plants and animals.

Explanation: The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.

This subregion is mostly submerged – it is only exposed at the point of low tide and for a longer period of time during extremely low tides. This area is teeming with life

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.

* 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.

What determines whether a material melts or burns when heated?

Answers

The combustion temperature of a material determines whether a material melts or burns

Materials whose combustion temperatures are lower than their melting point gets burnt instead of melting, because before the temperature of the material is raised up to the melting point temperature,  the materials gets combusted at a lower temperature known as the combustion temperature

Melting is physical change and is controlled by the physical property ( melting point ) while burning is chemical change which is irreversible.

Hence we can conclude that The combustion temperature of a material determines whether a material melts or burns

Calcium is a metal.
Word equations for two reactions of calcium are shown.
calcium + oxygen

calcium + hydrochloric acid → calcium chloride + hydrogen
The equation for the reaction of dilute hydrochloric acid with calcium is
Ca + 2HCl → CaCl2 + H2
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

6. What does a numerical subscript following a set of parentheses in a chemical
formula mean?

Answers

It is similar to the subscript next to an element, it indicates how many of the group or polyatomic ion in parentheses are present in the formula.

As an example, calcium hydroxide is Ca(OH)2 The subscript indicates that this formula contains two hydroxide ions.

A numerical subscript following a set of parentheses represents the number of the group or poly-atomic ion in parentheses are present in a chemical  formula.

As an example, calcium hydroxide is [tex]\bold { Ca(OH)_2 }[/tex] . The subscript (2) indicates that calcium hydroxide contains two hydroxide ions.

Therefore, A numerical subscript following a set of parentheses represents the number of the group or poly-atomic ion in parentheses are present in a chemical  formula.

What characterizes a system at equilibrium?
O A. The system is changing at an even rate.
B. The system has stopped changing.
O C. The system cannot undergo change.
D. There is no net change to the system.

Answers

Answer:

D. There is no net change to the system

Explanation:

Equilibrium means "equal". In a chemical system, changes occur in substances called the reactants to produce another substance called the products. These changes from reactants to products and vice versa occur at an uneven rate until EQUILIBRIUM is reached.

In other words, equilibrium is attained when the reactants and products are formed at an equal or constant rate i.e. There is no net change to the system. For example, in the chemical system below:

A + B ⇌ C + D

This system is said to be at "EQUILIBRIUM" if the rate of reaction of the reactants (A and B) is equal to that of the products (C and D). That is, there is no net change (difference) in the reaction rate.
