In the lab you react 2.0 g of Na2CO3 with enough CaCl2. According to the reaction Na2CO3 + CaCl2 -> CaCO3 + 2NaCl How much Ca
vlada-n [284]

Answer:

1.89 g CaCO₃

Explanation:

You will have to use stoichiometry for this question.  First, look at the chemical equation.

Na₂CO₃  +  CaCl₂  ==>  2 NaCl  +  CaCO₃

From the above equation, you can see that for one mole of Na₂CO₃, you will produce one mole of CaCO₃.  This means that however many moles of Na₂CO₃ you have in the beginning, you will have the same amount of moles  of CaCO₃, theoretically speaking.

So, convert grams to moles.  You should get 0.0189 mol Na₂CO₃.  This means that you will get 0.0189 mol CaCO₃.  I'm not sure what units you want the answer in, but I'm going to give it in grams.  Convert moles to grams.  Your answer should be 1.89 g.

N2 + 3H2 = 2NH3

in this question, we are dealing with only NH3 and H2 so we only focus on that

since the ratio of H2 to 2NH3 is 3:2, we say that

3 liters of H2 = 2 liters of 2NH3

3.6 litres of H2 = x liters of 2NH3

We cross multiple to give:

3 × x = 3.6 × 2

3x = 7.2

Divide both sides by 3

x = 7.2 ÷ 3

x = 2.4liters

Trava [24]

Answer:

Explanation:

Figure 6. An instant cold pack consists of a bag containing solid ammonium nitrate and a second bag of water. When the bag of water is broken, the pack becomes cold because the dissolution of ammonium nitrate is an endothermic process that removes thermal energy from the water.
