1. Zinc metal reacts with 100 mL of 6.00 M H2SO4. How many grams of Zinc Sulfate are produced and how many liters of Hydrogen gas would be released?

2.A 211 g sample of BaCO3 is reacted with HNO3. Assuming the acid is present is excess, what mass and volume of CO2 gas will be produced?

1. 96.882 grams of Zinc Sulfate are produced  and 0.0012 litres of hydrogen is gas formed.

2 . 46.65 grams is the mass of carbon dioxide gas formed and its volume is 23.74 litres.

Explanation:

1) Data given:

volume of Sulphuric acid = 100 ml or 0.1 litre

molarity of sulphuric acid = 6M , number of moles of sulphuric acid = 0.6 moles

number of moles = molarity x volume

                                   6 x 0.1

number of moles = 0.6

Zinc sulphate formed =?

hydrogen gas released =?

balanced chemical reaction

Zn + ⇒ ZnS +

1 mole of sulphuric acid reacted it formed 1 moles of zinc sulphate and 1 mole of hydrogen gas

so,  0.6 moles of sulphuric acid will give 0.6 moles of zinc sulphate and 0.6 mole of hydrogen gas.

mass = atomic mass x number of moles

mass = 161.47 x 0.6

mass of zinc sulphate formed =96.882 grams

litres of hydrogen gas formed = 0.6 x 2

                                                   = 1.2 ml

hence 0.0012 litres of hydroge gas formed

2)  Data given:

mass of barium carbonate = 211 grams

atomic mass of barium carbonate = 197.34 grams/mole

balanced reaction:

BaC + 2HN ⇒ Ba(N)2 +C + O

number of moles of barium carbonate =

putting values in the equation:

number of moles =

                           = 1.06 moles

from the reaction

1 mole of BaCO3 reacted to give 1 mole barium nitrate and 1 mole of carbon dioxide gas

so 1.06 moles of BaCO3 will give 1.06 moles each barium nitrate and carbon dioxide gas

mass = atomic mass x number of moles

mass of carbon dioxide = 1.06 x 44.01

                                        = 46.65 grams

assuming CO2 at STP, we apply ideal gas law

PV = nRT

here T = 273 K, P= 1 atm, R= 0.08201 L atm/mole K

V =

V =

V = 23.74 Litres

lol idk man i guess u gotta ask bill nye the science guy

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
