Answer:
26.74g
Explanation:
The equation of the reaction is;
SIO₂ + 3C --> SiC +2CO
From the balanced equation, the relationship between SiC and C is;
3 mol of C produces 1 mol of SiC
Converting mol to mass using; Mass = moles * Molar mass
Mass of SiC = 1 mol * 40.11 g/mol = 40.11g
This means;
3 mol of C produces 40.11g of SiC
2 mol of C produces xg of SiC
3 = 40.11
2 = x
x = 2 * 40.11 / 3 = 26.74g

Answer:
1.041g is the maximum sigle dose for the person
Explanation:
The maximum dose for acetaminophen is 15.0mg / kg of body weight for adults
To find the maximum single dosage for a person who weighs 153lb we must convert the lb to kg (1lb = 0.4536kg):
153lb * (0.4536kg / 1lb) =<em> 69.4kg is the mass of the person</em>
<em />
As the maximum dose is 15.0mg / kg, the dose of the person is:
69.4kg * (15.0mg acetaminophen / kg) =
<h3>1041mg = 1.041g is the maximum sigle dose for the person</h3>
Answer:
No, just because carbon did not react with water, does not mean it wouldn't react with a different compound.
Explanation:
It is common knowledge that carbon is not in group 18, because it is found in all living compounds, and this means it must be reactive with many compounds. We know that water is not very reactive, but it is a good solvent. Meaning that many compounds can dissolve in water, but not chemically react with it. Carbon however is not very soluble because it does not create dipoles or hydrogen bonds. This means it will not show any change when in the presence of water, but if combined with oxygen, can form carbon dioxide.
The answer should be 5 cu
