Answer:
=<em><u> 0.42 moles of CO2 </u></em>
Explanation:
From Avogadro's constant
6.02×10^23 molecules are in 1 mole of CO2
2.54×10^23 molecules will be in
=[(2.54×10^23) ÷ (6.02×10^23)]
= 0.42 moles of CO2
The answer is Strontium Nitride
Answer:
Explanation:
HCl + NaOH = NaCl + H₂O.
1 mole 1 mole 1 mole 1 mole
6.93 g of hydrochloric acid = 6.93 / 36.5 = .189 mole of HCl
2.4 g of NaOH = 2.4 / 40 = .06 mole of NaOH
NaOH is in short supply so it is the limiting reagent .
1 mole of NaOH reacts with 1 mole of HCl to give 1 mole of Water
.06 mole of NaOH will react with .06 mole of HCl to give .06 mole of water
Water formed = .06 mole
= .06 x 18 = 1.08 g
= 1.1 g

<span> 250g H2SO4 x 1moleH2SO4/ 98g mole H2SO4 x 4moles Oxygen/1moleH2SO4 x 1moleOxgen/16g Oxygen
= 163.27g Oxygen
my figures aren't exact....so it's 160g </span>

Answer: Option (3) is the correct answer.
Explanation:
When a more reactive element or atom replaces a less reactive atom then this type of reaction is known as single displacement reaction.
In the given reaction, potassium iodide reacts with fluorine and results in the formation of potassium fluoride and iodine.
Here, fluorine being more reactive displaces iodine from potassium iodide.
Therefore, it is a single replacement or displacement reaction.
