Maya made this picture to represent a chemical reaction:

Which of the following statements best explains the type of chemical reaction represented by Maya's picture?

It is neither a synthesis reaction nor a decomposition reaction because two reactants form two products.

It represents a decomposition reaction because two reactants break apart and form two products.

It is neither a synthesis reaction nor a decomposition reaction because the total mass of the products is less than the total mass of the reactants.

It represents a synthesis reaction because the same atoms are present in the reactants and products.

you can explore the structure of atoms as you add protons, neutrons, or electrons to a model and the name of the element you have created

Explanation:

Answer:

CaBr2 is a colorless solid and the charge on Calcium is +2

Explanation:

CaBr2 is a colorless solid at room temperature.

Other properties include -

a) It is a crystalline solid

b) Melting point of 765°C.

c) It is deliquescent

d) Soluble in water and absolute alcohol.

The charge of Br is -1. Here two atoms of Br attaches with one atom of calcium. Hence the charge of calcium is +2

Answer:

[tex]6.05211\times 10^{23}\ \text{atoms}[/tex]

Explanation:

Moles of carbon dioxide = 1.005 moles

[tex]N_A[/tex] = Avogadro's number = [tex]6.022\times 10^{23}\ \text{mol}^{-1}[/tex]

Number of atoms is given by

[tex]\text{Moles}\times N_A=1.005\times 6.022\times 10^{23}[/tex]

[tex]=6.05211\times 10^{23}\ \text{atoms}[/tex]

The number of atoms in the given amount of moles of carbon dioxide is [tex]6.05211\times 10^{23}\ \text{atoms}[/tex].

Explanation:

The heat is needed to increase the temperature of 19.3 g lead from 22°C to 41° C is 46.9 J or 46.9 MCT.

Heat is defined as a form of energy related to the motion of an atom or molecules. It can also be defined as transfer of kinetic energy from one medium or object to another medium or object

Heat energy can be calculated as

q = mcΔT

ΔT = 41°C - 22°C = 19°C

So q = 19.3g x 0.128J/g °C x 19°C

        = 46.9 J or 46.9 MCT

Thus, the heat is needed to increase the temperature of 19.3 g lead from 22°C to 41° C is 46.9 J or 46.9 MCT.

Answer:

The factors that determine the amount of elastic potential energy being stored include the type of material and the amount it is deformed. The more an object is deformed, the more stored energy it has.

Answer:

F₂ (g) + FeI₂ (aq) →  FeF₂ (aq) +  I₂ (l)

Explanation:

Our reactants are:

F₂ → Fluorine gas, a dyatomic molecule

FeI₂ → Iron (II) iodine

Our products are:

I₂ → Iodine

FeF₂ → Iron (II) fluoride

Then, the reaction is:

F₂ (g) + FeI₂ (aq) →  FeF₂ (aq) +  I₂ (l)

We see it is completely balanced.

Answer:

The gas pressure inside the flask is higher than outside the flask ornthe atmospheric pressure.

Explanation:

Given a U-tube manometer with water in between each arm of U-tube. One end is open to the atmosphere while one end is sealed to a flask filled with a gas. The water in the open end of the tube is experiencing a pressure equal to the atmospheric pressure whereas the water at the end sealed of to the flask is experiencing pressure due to the gas in the flask.

If the water level in both arms of the tube are equal, then the pressure due to the gas is equal to atmospheric pressure.

If the water level in the arm sealed to the gas is higher than that of the open end, The gas pressure is less than the atmospheric pressure.

If the water level in the arm sealed to the flask is lower than the open end, the pressure due to the gas is higher than atmospheric pressure.

From the question, when the water level is higher outside the flask than inside, then the gas pressure inside the flask is higher than the atmospheric pressure.

Answer:

6.6 g

Explanation:

La ecuación de la reacción es;

MnO2 + 4 HCl -------> MnCl2 + Cl2 + 2H2O

Número de moles de HCl que reaccionan = 7.5g / 36.5 g / mol = 0.21 moles

Dado que;

4 moles de HCl producen 1 mol de MnCl2

0,21 moles de HCl producen 0,21 * 1/4 = 0,0525 moles de MnCl2.

Masa de MnCl2 = 125,844 g / mol * 0,0525 moles = 6.6 g

Answer:

26.88 L

Explanation:

When any gas is held under standard conditions, one mol will occupy 22.4 liters.

With the above information in mind, we can calculate how many liters would 1.20 moles of CH₄ gas occupy under standard conditions:

1.20 mol * 22.4 L/mol = 26.88 L

So 1.20 moles of CH₄ would occupy 26.88 liters.

Answer:

A. 6atm

Explanation:

Using pressure law equation:

P1/T1 = P2/T2

Where;

P1 = initial pressure (atm)

T1 = initial temperature (K)

P2 = final pressure (atm)

T2 = final temperature (K)

According to this question;

P1 = 3 atm

P2 = ?

T1 = 120K

T2 = 240K

Using P1/T1 = P2/T2

3/120 = P2/240

Cross multiply

240 × 3 = P2 × 120

720 = 120P2

P2 = 720/120

P2 = 6atm

Explanation:

Water vapor is when water molecules are present in the air, while steam is water heated to the point that it turns into gas. In simplified science, both are referred to as the gaseous state of water. Steam is usually white or translucent in nature, while water vapor can be clear or translucent.

Steam is simply, water vapor. Hence, the key difference between steam and vapor is that steam is the gaseous state of water whereas vapor is the gaseous state of any substance. Moreover, steam is typically invisible while the vapor of some substances is colorful.
