How many moles of H2O are produced when 64.0 g C2H2 burns in oxygen
Gnoma [55]
The balanced chemical reaction will be: 

C2H2 + 5/2O2 = 2CO2 + H2O

We are given the amount of C2H2 being burned. This will be our starting point.

64.0 g C2H2 (1 mol C2H2 / 26.02 g C2H2) (1 mol H2O/1mol C2H2) ( 18.02 g H2O/1mol H2O) = 44.32 g H2O.

Thus, the answer is 44.32 g H2O.

Cacl2+2AgNO3(aq)-> Ca(No3)2 (aq)+2AgCl (s) if 25.0mL of a 2.00 m CaCl2 solution is used for the reaction shown above how many
antiseptic1488 [7]

Answer:

n_{Cl^-}=0.1molCl^-

Explanation:

Hello,

In this case, given the 2.00 M solution, we can compute the moles of calcium chloride that reacted:

n_{CaCl_2}=2.00\frac{mol}{L} *25.0mL*\frac{1L}{1000mL}=0.05molCaCl_2

Then, since in one mole of calcium chloride, we find two moles of chloride ions (see subscript), we can compute the moles of chloride ions that were involved in the reaction as shown below:

n_{Cl^-}=0.05molCaCl_2*\frac{2molCl^-}{1molCaCl_2}\\ \\n_{Cl^-}=0.1molCl^-

Best regards.

What is the molarity of 1.5 liters of an aqueous solution that contains 52 grams of lithium fluoride, LiF, (gram-formula mass =2
denis23 [38]
The answer is (1) 1.3 M. The first thing you need to do is to convert the unit of gram to mole. The mol number of LiF is 52/26=2 mol. Then using the volume to calculate the molarity: molarity=2/1.5=1.3 M.
