1. how many grams of each sulphur and oxygen are needed to produce 6.023×10^23 molecules of SO2 according to the reaction:S + O2>SO2.
2.
calculate the no of atoms of C and H in 4 g of methane.​

1.No of moles of SO2=6.022*10^24/AVAGARDOS NUMBER

No of moles=10

1 Moles of So2 contains 1 moles of s and 2 moles of o

10 mole of so2 contains 10 moles of s and 20 moles of o

No of moles of o=weight in gram of o/atomic weight

20*16=Weight =320 kg

And similarly for sulphur(atomic weight32)

2.1.5055x10^23 C atoms and 6.022x10^23 H atoms

Molar Mass of 1 molecule of methane(CH4) = 12 +

4 = 16g/mol =

That is, 16g if CH4 contain 1 mole molecule of it

= 6.022x1023 molecules of CH4 which consists of 1 mole of C atoms and 4 moles of H atoms.

=> 4 g of CH4 contains 1/4 x 6.022x1023

molecules

= 1.5055*10^23 molecules of CH4

= 1.5055*10^23 C atoms and 6.022x10^23 H atoms

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
