Answer:

WHITE BLOOD SELL?

Explanation:

Answer: The layers of the rocks in one region of the parks are smooth and distinct, which are evidence of many, many years of deposition. The layers on the rocks are because of different deposition of sediments. Different sediments deposited over the rocks through wind, water and ice over the ages

Answer:

1. Core electrons = 1s²; Valence electrons = 2s² and 2p³

2. Core electrons = 1s², 2s²,m2p⁶; Valence electrons = 3s² and 3p⁵

Explanation:

The electrons in an atom of an element are generally divided into two groups: the core electrons and the Valence electrons

Valence electrons are those electrons which are located of or found in the outermost shell or highest energy level of an atom. These valence electrons are the one that determine the chemical reactivity of an atom as they can participate in bond formation between atoms of the same element or with atoms of other elements. The valence electrons also, generally determine the group to which an element will belong to.

Core electrons on the other hand, are those electrons which are found within the innermost shell or lowest energy levels of the atom. They are strongly attracted to the nucleus of atom and do not take part in chemical bonding. However, they play the important role of shieldingnthe valence electrons from the positive charge of the nucleus thereby assisting the valence electrons in bond formation.

Answer:

n = 1.14 mol

Explanation:

Hello there!

In this case, according to the ideal gas law:

[tex]PV=nRT[/tex]

It is possible to solve for the moles of the gas given the volume, temperature and pressure:

[tex]n=\frac{PV}{RT}[/tex]

Thus, we plug in 14.0 L, 300 K and 2.0 atm to obtain:

[tex]n=\frac{2.0atm*14.0L}{0.08206\frac{atm*L}{mol*K}*300K}\\\\n=1.14mol[/tex]

Best regards!

Answer:

4180J

Explanation:

(25.0g)(4.184J/g°C)(75°C-35.0°C)

(25.0g)(40.0°C)(4.184J/g°C)

(1.00*10³g°C)(4.184J/g°C) = 4184J

use sig figs:

4180J

Answer: We know that, 1 mole of any substance contain 6.022 X 10^23 atoms/molecules. Thus, 2.14 moles are present in 1.29x10^24 hydrogen atoms in HF.

Explanation:

divide it by avogadro's constant

that is 6.02 × 10²³

1.2 × 10²⁴ / 6.02 × 10²³

= 2 mol

SNAZZY

Answer:

The water is clearly close to boiling temperature when you add the ice. So, initially the ice cools the water that is near it to near 0degC. Water between about 0 and 8 degrees is more dense than hotter water, so the cold water sinks to the bottom.Jun 14, 2020

Answer:

By using the techniques of archeology.

Explanation:

Students recover an individual's remains from a surface grave by using the techniques of archeology field to scrape away the layers of soil from that remains in a way that the remains can't be damaged. If they find the remains within 10 centimeters of digging, they can dig down further in order to dig out all the remains safely. The instruments of archeology field are used because they are light and can be used to dig out fossils of ancient organisms.

Answer:

62.36 g

Explanation:

AgNO3 + H2SO4 - > Ag2SO4   + HNO3

The balanced equation is given as;

2AgNO3 + H2SO4 → Ag2SO4 + 2HNO3  

From the equation;

2 mol of AgNO3 reacts with 1 mol of H2SO4

if 0.200 moles of AgNO3 react with 0.155 moles of H2SO4

The limiting reactant us AgNO3 as it determines the amount of products to be formed.

2 mol of AgNO3 produces 1 mol of Ag2SO4

0.2 mol of AgNO3 would produce x mol of Ag2SO4

Solving for x;

2 = 2

0.2 = x

x =0.2 * 2/ 2 = 0.2 mol

Converting moles to mass;

Mass = Number of Moles * Molar mass

Mass = 0.2 mol * 311.8 g/mol

Mass = 62.36 g

A:The number of protons

Answer:

b) 2H+(aq) + 2C1-(aq) + Zn(s) → H2(g) + Zn2+(aq) + 2Cl-(aq)

Explanation:

The equation is given as;

2HCl(aq) + Zn(s) + H2(g) + ZnCl2(aq)

In writing an ionic equation, only the aqueous compounds dissociates into ions. This means HCl and ZnCl2 would dissociate to form ions.

This is given as;

2H+  +  2Cl-  + Zn(s) --> H2(g) + Zn2+  + 2Cl-

The correct option is;

b) 2H+(aq) + 2C1-(aq) + Zn(s) → H2(g) + Zn2+(aq) + 2Cl-(aq)

Answer:

3.48 g

Explanation:

Chemistry is often referred to as the central science because it joins together physics and mathematics, biology and medicine, and the earth and environmental sciences. Knowledge of the nature of chemicals and chemical processes therefore provides insights into a variety of physical and biological phenomena.

Answer:

Science chemistry is the investigation of issue, examining its design, properties and conduct to see what happens when they change in substance responses. Thusly, it very well may be viewed as a part of actual science, close by stargazing, physical science and studies of the planet including geography.

Answer:

The change of state that has occurred is from a gas to a liquid

Note: The question is incomplete. The complete question is given blow.

H₂O is initially present in a state where its molecules are far apart. During a change of state, its molecules slow down. Which change of state has most likely taken place?

from a gas to a liquid

from a liquid to a gas

from a solid to a liquid

from a gas to a plasma

Explanation:

Water can exists in three states: as gaseous water vapor, as liquid water, and as solid ice. Each of these states of water can be interconverted from one to another by the addition or removal of heat in a process known as change of state.

Liquid water can be converted to solid ice by the removal of heat, while solid ice ice can be converted to liquid water by the addition of heat. Also, liquid water can be converted to water vapor by the addition of heat, while water vapor can be converted to liquid water by the removal of heat.

Of the three states of water, the one in which the molecules are farthest apart is in the gaseous state. The molecules have high kinetic energy and move randomly while colliding with one another. When a heat is removed from these highly energetic molecules, the molecules slow down and lose some of their kinetic energy and a change of  occurs from gaseous to liquid state.

Therefore, the change of state that occurred as described, is from gas to liquid.

Answer:

25000mL, 0.025m³, 0.88ft³, 25dm³

Explanation:

Para resolver esta pregunta debes tener claros los factores de conversión:

1L = 1000mL

1000L = 1m³

1L = 0.035315ft³

1L = 1dm³

25L son:

25L * (1000mL / 1L) = 25000mL

25L * (1m³ / 1000L) = 0.025m³

25L * (0.035315ft³ / 1L) = 0.88ft³

25L * (1dm³ / 1L) = 25dm³
