how many grams of ammonium carbonate are needed to decompose in order to produce 6.52 g of carbon dioxide?
defon

Answer:

<u>= 14.24g of </u>(NH4)_{2}CO_{3}<u> is required.</u>

Explanation:

Reaction equation:

(NH4)_{2}CO_{3} → 2NH_{3} + CO_{2} + H_{2} O

Mole ratio of ammonium carbonate to carbon dioxide is 1:1

1 mole of CO2 - 44g

?? mole of CO2 - 6.52g

= 6.52/44 = 0.148 moles was produced from this experiment.

Therefore, if 1 mole of (NH4)_{2}CO_{3} - 96.09 g

0.148 mol of (NH4)_{2}CO_{3} --  ?? g

=0.148 × 96.09

<u>= 14.24g of </u>(NH4)_{2}CO_{3}<u> is required.</u>

A student added 500 mL of water to 200 mL of 0.20M NaCl solution. Which of the following is True?
tamaranim1 [39]

Option B is true , the same number of moles of solute in both solution is the same.

<h3>What is Molarity?  </h3>

Molarity is the ratio of no of moles as per liter solution. It is denoted by M and SI unit is also M or moles/litre.

Molarity = no . Of moles/Volume (L)  

In this question the amount of solution is increased means the volume is increased from 500-700ml it is increased , Molarity is inversly proportional of Volume

it will decrease if volume increase. Adding water do affect the concentration of the solution. The no. Of moles of solute remains because there no increament in amount of NaCl .

Hence ,option B is more correct

For the reaction PCl5(g) + heat PCl3(g) + Cl2(g), what will happen when the volume is increased?
Fiesta28 [93]
Answer: There will be a shift toward the products. 

The effect of increasing volume will be similar to decreasing pressure, it will shift the equilibrium into the side with higher molecule count. In the reaction above, the product molecule count is 1 (one PCl5) while the product is 2 (one PCl3 + one Cl2). So, increasing volume will increase the rate of product formation.
