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

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
