Explain whether a red apple is opaque or transparent and why it appears red.
borishaifa [10]
It is opaque because you can't see anything on the other side of the apple.


An apple is red because of the frequency of light shining on it makes it seem that it is red, as it is reflected. It seems it is red because it reflects infrared waves.

A sample of oxygen gas at a pressure of 0.656 atm and a temperature of 27.2 °C, occupies a volume of 10.7 liters. If the gas is
sladkih [1.3K]

Answer:

The correct answer is 0.536 atm.

Explanation:

The formula to use to solve the given question is,

P1V1 = P2V2

Based on the given information, the initial pressure (P1) of the oxygen gas is 0.656 atm, the initial volume (V1) is 10.7 L. The new volume (V2) given is 13.1 L, there is a need to find the new pressure of the gas (P2).

Now putting the values in the above equation we get,

0.656 atm * 10.7 L = P2 * 13.1 L

P2 = 0.656 atm*10.7 L/13.1 L

P2 = 0.536 atm

How many moles of ammonia, NH,, are contained in<br><br> 6.21 x 1024 molecules of ammonia?
ankoles [38]

Answer:

10.32 moles of ammonia NH₃

Explanation:

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

Number of molecules = 6.21×10²⁴ molecules

Number of mole of NH₃ =?

The number of mole of NH₃ can be obtained as follow:

From Avogadro's hypothesis,

6.02×10²³ molecules = 1 mole

Therefore,

6.21×10²⁴ molecules = 6.21×10²⁴ / 6.02×10²³

6.21×10²⁴ molecules = 10.32 moles

Thus, 6.21×10²⁴ molecules contains 10.32 moles of ammonia NH₃
