Question

while verifying the law of conservation of mass Smith added 3.5 gram of magnesium metal into 13.7 gram of hydro chloric acid if the mass of magnesium chloride formed is 13.8 gram what is the mass of illuminated hydrogen gas if the law of conservation of mass of massis correct. (a) 3.2 g (b) 3.4 g (c) 4.3 g (d) 5g.​

Answer 1

Answer:

3.2 grams mass is high acid ic

Answer 2

Answer:

Explanation:

equivalent of mgcl2 = equivalent of h2 gas

13.8/95 * 2 = w/2 *

for factor of h2 gas you need to balance the above reaction

mg+hcl = mgcl2 + h2

mg+ 2 hcl = mgcl2 + h2

here apply factor of h2 = coefficient of other atom * factor of other atom / coefficient of h2

factor of h2 = 2

as valency factors are same so mole 1 = mole 2

0.29 grams will be liberated
