Answer:

D. Nathan applies enough force through pushes to move the piano

Explanation:

What moves the piano is a net force that is applied through the effort of Nathan on the instrument.

Force is a pull or push on a body.

When force is applied on a body, it causes the state of motion of the body to change.

Therefore, if a body has a net force greater than zero, the body will in likewise begin to move. As Nathan pushes on the piano, it will eventually move.

PLZ HELP IM CONFUSED
Marina CMI [18]

Answer:

9.1 mol

Explanation:

The balanced chemical equation of the reaction is:

CO (g) + 2H2 (g) → CH3OH (l)

According to the above balanced equation, 2 moles of hydrogen gas (H2) are needed to produce 1 mole of methanol (CH3OH).

To convert 36.7 g of hydrogen gas to moles, we use the formula;

mole = mass/molar mass

Molar mass of H2 = 2.02g/mol

mole = 36.7/2.02

mole = 18.17mol

This means that if;

2 moles of H2 reacts to produce 1 mole of CH3OH

18.17mol of H2 will react to produce;

18.17 × 1 / 2

= 18.17/2

= 9.085

Approximately to 1 d.p = 9.1 mol of methanol (CH3OH).
