Answer:

With the use of same chemicals, same gas will be produced while the use of different chemicals, different gases will be produced.

Explanation:

The same gas was produced in each assignment if the same chemicals are mixed with each other while different gases were produced in each assignment when different chemicals are allowed to mix. If every time, same chemicals and same concentration of chemicals are mixed together, the result will be the same means production of same gas but if different chemicals are allowed to mix, then the product will be the production of different gases.

What is the molarity (M) of a solution with 2 mol of NaCl in 0.50 L of solution?

irinina [24]

Answer:

The answer to your question is 4 M

Explanation:

Data

NaCl 2 moles

Volume = 0.5 l

Molarity = M

Process

1.- Write the formula of Molarity

$Molarity = \frac{number of moles}{volume (liters)}$

2.- Substitution

$Molarity = \frac{2 moles}{0.5 liters}$

3.- Simplification and result

Molarity = 4 M

A 31.3-g sample of ammonium carbonate contains ________ mol of ammonium ions.

Leona [35]

<span>We need to calculate the equivalent amount in units of moles of ammonium ions from the mass units. For this we need the molar mass of the substances involved. We calculate as follows:

31.3 g </span>(NH4)2CO3 ( 1 mol (NH4)2CO3 / 96.09 g (NH4)2CO3) ( 2 mol NH4 / 1 mol (NH4)2CO3 ) = 0.65 mol <span>ammonium ions</span>
