Answer:
9.4L
Explanation:
Given parameters:
Mass of Cl₂ gas = 30g
Unknown:
Volume of gas = ?
Solution:
To solve this problem, let us assume that this reaction takes place under standard temperature and pressure conditions.
Therefore;
Volume of gas = number of moles x 22.4
To find the number of moles;
Number of moles = ![\frac{mass}{molar mass}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D)
molar mass of Cl₂ = 2(35.5) = 71g/mol
Number of moles =
= 0.42mole
So;
Volume of gas = 0.42 x 22.4 = 9.4L
Answer:
They are formed by windblown sand collecting around an obstruction. As organic matter is deposited by wind and waves, low herbs colonize the dune. As these plants collect more sand and organic matter, the dune increases in height becoming the fore dune.

Answer:
4.08moles
Explanation:
The balanced equation of this reaction is given as:
H2SO4 + 2NaOH -> Na2SO4 + 2H2O
From the above balanced equation, 1 mole of H2SO4 is needed to react with 2 moles of NaOH.
Using the formula below to calculate the number of moles in 200g of H2SO4;
mole = mass/molar mass
Molar mass of H2SO4 = 1(2) + 32 + 16(4)
= 2 + 32 + 64
= 98g/mol
number of moles = 200g ÷ 98g/mol
n = 2.04mol
Since 1 mole of H2SO4 is needed to react with 2 moles of NaOH.
Then, 2.04mol of H2SO4 is needed to react with 2.04 × 2/1 = 4.08moles of NaOH.
