Answer:
It is a covalent bond because both carbon and oxygen are nonmetals. The formula will be CO² because the electrons between the atoms are being shared equally.
Answer:
12.084 lb
Explanation:
1 gram = 0.00220462 lb
multiply number of grams by 0.00220462
Ex. 2000 g x 0.00220462 = 4.409 pounds

Answer is: 15.30 kilojoules of heat are needed to completely vaporize C₄H₁₀<span>.
m(</span>C₄H₁₀) = 42.8 g.
M(C₄H₁₀) = 74.12 g/mol.
n(C₄H₁₀) = m(C₄H₁₀) ÷ M(C₄H₁₀).
n(C₄H₁₀) = 42.8 g ÷ 74.12 g/mol.
n(C₄H₁₀) = 0.577 mol.
Q = n(C₄H₁₀) · ΔHvap.
<span>Q = 0.577 mol </span>· 26.5 kJ/mol.
<span>Q = 15.30 kJ, heat of butane.

Answer:
The energy released is 13.53j
Explanation:
Q = Mc∆temp.
Q = energy
M = mass
c = specific heat capacity
∆temp. = change in temperature
Q = 1 x 0.902 x (35 - 20)
Q = 0.902 x 15 = 13.53j
