And another fuel very used in rockets is kerosene which is a hydrocarbons mixture of other compounds that fuel.
Answer:
65.38 u
Explanation:
Change each percent abundance into decimal form (by dividing by 100) then multiply each by the atomic mass of it's isotope. Add together each isotope to get the average atomic mass of the element.
If someone spills hydrogenflouride, which is <em>extremely</em> toxic, it would be essential to neutralize the acid.
A I think if not sorry my bad
Balance Chemical Equation is,
<span>CaO </span>₍s₎ <span>+ CO</span>₂ ₍g₎ <span>→ CaCO</span>₃ ₍s₎
According to Equation
56.07 g of CaO when reacted with excess CO₂ produces = 100.08 g of CaCO₃.
Then,
1.8 g of CaO is reacted with excess CO₂ = X g of CaCO₃ will produce.
Solving for X,
X = (100.08 g × 1.8 g) ÷ 56. 07 g
X = 3.21 g of CaCO₃
