I believe the correct answer would be <span>C2H5OH + 3O2 → 2CO2 + 3H2O . A combustion reaction is one that reacts with oxygen and produces carbon dioxide and water. As you can see, option A falls into that category and is a balanced reaction.</span>

A current of 12 amps is measured in a circuit with a total resistance of 9.0 ohms. What is the size of the voltage source that s

Serjik [45]

Data:
i (current) = 12 A
R (resistance) = 9.0 Ω
V (voltage) = ? (volts)

Formula:
$V = R*i$

Solving:
$V = R*i$
$V = 9.0*12$
$\boxed{\boxed{V = 108\:volts}}\end{array}}\qquad\quad\checkmark$

Four uniform objects having the same mass and diameter are released simultaneously from rest at the same distance above the bott

Jet001 [13]

The one with the majority of its mass furthest away from its center will reach the bottom last. The thin walled cylinder has all of its mass at the edge of itself, meaning its mass is the furthest from its center. If we take a look at the solid cylinder, it has some mass at its edge, but it also has a lot of mass very close to its center so it will roll faster than the thin walled cylinder. And the thin walled cylinder will be slower than the normal hollow cylinder because even though the hole cylinder doesn't have any mass at its center it does have some mass closer to its center than the thin walled cylinder.

So the last one to reach the bottom is the thin walled cylinder.
