What happens when Ca(NO3)2 and Na2CO3 combine?

Answers

When the two compounds are allowed to be in contact and reacts the product would be sodium nitrate (NaNO3) and calcium carbonate (CaCO3). This reaction is a double displacement reaction. The balanced equation is :

Ca(NO3)2 + Na2CO3 = 2NaNO3 + CaCO3

Which is the most important factor in determining the state of a substance?

Answers

Out of the following given choices;

A. the size of the atoms in a substance

B. the number of molecules in a substance

C. the position of the electrons on the outer valence shells

D. the balance between intermolecular forces and kinetic energy

The answer is D. The kinetic energy of the molecules is determines by the temperatures of the substance. The higher the temperatures, the higher the kinetic energy of the molecules. The molecules subsequently move and collide with higher energies and overcome intermolecular forces. This allows the substance to changes state from solid to liquid and eventually to gas (with increasing kinetic energy).

The most important state in determining the state of a substance is temperature. This is because the kinetic energy of a substance's molecules depend on its temperature. For example, an increase in temperature speeds up the movement of molecules. A decrease in temperature slows down the movement of molecules.

This is important because by increasing or decreasing a substance's temperature, you are also adding or removing energy from it. And when a substantial amount of energy has been added or removed, a substance can change its state from solid > liquid > gas or the other way around.

How many moles in 28 grams of CO2

Answers

In the given question, in 28 grams of $\rm CO_2$ molecule 0.636 moles are present.

A mole is the amount of a substance which comprises exactly $6.022* 10^(23)$ 'elementary entities' of that substance.

To find the number of moles in 28 grams of $\rm CO_2$ , we first need to determine the molar mass of $\rm CO_2$ .

Molar mass of $\rm CO_2$ = 12.01 g/mol (carbon) + 2(16.00 g/mol) (oxygen)

= 44.01 g/mol

Now that we know the molar mass of $\rm CO_2$ , we can use the following formula to calculate the number of moles:

$\rm Number \ of\ moles = \frac {mass \ of \ sample\ (in \ grams) }{ molar\ mass}$

$\rm Number\ of\ moles = \frac {28 \ g }{44.01\ g/mol }$

= 0.636 mol

Therefore, there are 0.636 moles in 28 grams of $\rm CO_2$ .

The component which dissolves in a solution is called the.....

Answers

Explanation:

A solution consists of two type of substances. These are solute and solvent.

A solvent is defined as the substance present in lesser amount as compared to a solvent. A solute is able to dissolve in a solvent.

For example, sugar dissolves in water. Here, sugar is the solute and water is the solvent.

Combination of both solute and solvent results in the formation of a solution.

Whereas a solvent is a substance that is present in more quantity as compared to a solute.

Thus, we can conclude that the component which dissolves in a solution is called the solute.

The component which dissolves is called the Solute. It is dissolved by the Solvent.

How many moles are present in 4.7 liters of Argon gas at STP?

Answers

The answer for the following problems is mentioned below.

Therefore the number of moles present in Argon is 0.20 moles.

Explanation:

Mole:

The mass of a substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of $C^(12)$ .

Given:

volume (v) = 4.7 litres

Volume of argon at STP conditions = 22.4 litres

To find:

volume of argon at STP conditions

We know;

n = $(v)/(V)$

where;

n represents the no of moles

v represents the volume of the argon

V represents the volume of argon at STP

volume of the argon at STP conditions is 22.4 litres

So;

n = $(4.7)/(22.4)$

n = 0.20 moles

Therefore the number of moles present in Argon is 0.20 moles.
