The mass of an atom of carbon-12 is 1.993 × 10⁻²³ g.

1 C atom has a mass of 12 u.

1 mol of C atoms has a mass of 12 g.

∴ Mass of 1 C atom = 12 g/6.022 × 10²³ C atoms = 1.993 × 10⁻²³ g

The OAC simulation showed that warm air over a cold current:
vladimir2022 [97]

Answer:

Option B

Transfers energy to the water

Explanation:

Warm air transfers energy to the water when it flows over cold currents. This means that the warm air loses heat energy to the cold currents thus, raising its temperature.

Whenever there is a temperature difference between two bodies in contact with each other, the Fouriers law explains that there is always a transfer of heat from the hotter body to the colder body until they become the same temperature.

Thus, following this, heat will flow from the warm air to the cold currents.

Which of the following are correct for zero-order reactions?
GREYUIT [131]

Answer:

The answer is "Choice A and Choice B"

Explanation:

The Zero-Order reactions are usually found if a substrate, like a surface or even a catalyst, is penetrated also by reactants. Its success rate doesn't depend mostly on the amounts of the various reaction in this reaction.

Let the Rate = k

As \frac{dx}{dt} \ rate\ \  K_0 doesn't depend on reaction rate, a higher reaction rate does not intensify the reaction.

By the rate k_0 =\frac{dx}{dt}, the created based and the reaction rate is about the same.
