(NH4)2Cr2O7
Explanation:
Hope this somehow helped.
Answer:
Explanation:
A) When four moles of ammonia reacts with five moles of O2 gas, four moles of Nitrogen mono oxide liberates along with six moles of water.
B) When two moles pottasium nitrate (KNO3) is heated it dissociates into two moles of potassium nitrite liberates along with one mole of O2 gas.
C) When one mole of calcium reacts with two moles water, one mole of calcium hydroxide obtained & one of hydrogen gas released.
D) When two mole of Sodium bicarbonate (NaHCO3) is heated it gradually decomposes to one mole of Sodium carbonate (Na2CO3) obtained along with one mole of each Water & Carbon dioxide.
E) <em>The question needs to corrected,</em>
When two moles of carbon monoxide reacts with one mole oxygen two moles of carbon dioxide is released.
Answer:
a. 52.8
Explanation:
To find the number of moles of HCl we use the relation M₁V₁=M₂V₂
where M₁ is the initial molarity, M₂ the new molarity, V₁ the initial volume used, and V₂ the final volume obtained.
M₁=7.91 M
M₂=2.13 M
V₁=?
V₂=196.1 mL
Replacing these values in the relationship.
M₁V₁=M₂V₂
7.91 M× V₁=2.13 M×196.1 mL
V₁=(2.13 M×196.1 mL)/7.91 M
=52.8 mL
