Answer:

66800 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 200 g

Heat (Q) required =?

The heat required to melt the 200 g sample of water can be obtained as:

Mass (m) = 200 g

Latent heat of water (L) = 334 J/g

Heat (Q) required =?

Q = mL

Q = 200 × 334

Q = 66800 J

Thus, 66800 J of heat energy is required to melt the sample of water.

Solid, Liquid, and Gas

Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

aniked [119]

Answer:

Temperature usually increases when water condenses. What behavior of water is most directly responsible for this phenomenon? The release of heat by the formation of hydrogen bonds. Hydrogen bonds stabilize and keep the of ice farther apart than the water molecules of liquid water.

The reaction of nitrogen gas and oxygen gas to form nitrogen monoxide gas is shown below. If the measured concentrations of all
Anettt [7]

Answer:

The forward reaction is occurring at a faster rate than the reverse reaction.

Explanation:

Reaction quotient (Q) of the given reaction is -

                                     Q=\frac{[NO]^{2}}{[N_{2}][O_{2}]}

where [NO], [N_{2}] and [O_{2}] represents concentrations of respective species at a certain time.

Here [N_{2}]= 0.80 M, [O_{2}]= 0.050 M and [NO] = 0.10 M

So, Q=\frac{(0.10)^{2}}{(0.80)\times (0.050)}=2

Hence Q> K

It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of [N_{2}] and [O_{2}] which makes Q higher than K.
