Balance the following equations: i. H2SO4 + ….NaHCO3 → Na2SO4 + ….H2O + ……CO2
ii. H2 + I2 → ….HI
iii. …..NaOH + H2SO4 → Na2SO4 + …..H2O
iv. ……FeSO4 → Fe2O3 + SO2 + SO3
v. C3H6O2 + …..O2 → ….CO2 + …..H2O
b) Calculate the molecular masses of the following:
i. H2SO4

ii. CH4

iii. NH3

c) 56g of iron reacts with 71g of chlorine. How many grams of iron react with 35.5g of chlorine?

Explanation:

2 NaHCO3 (aq) + H2SO4 (aq) → Na2SO4 (aq) + 2 H2O (l) + 2 CO2 (g)

This is an acid-base reaction (neutralization): NaHCO3 is a base, H2SO4 is an acid.

This is a gas evolution reaction, CO2 is the formed gas.

SORRY

BUT I DON'T KNOW THESE ANSWERS

I TRIED BUT COULDN'T MAKE IT

SO SORRY

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
