How many terms are in the geometric series 5+313+229++6402,187?

2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂

Explanation:

 2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂  . . . . .  balanced combustion reaction

 C₄H₁₀ + 5O₂ ⟶ 5H₂O + 4CO₂  . . . . not balanced

The two reactions involving Ca are not combustion reactions.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
