How many molecules (not moles) of nh3 are produced from 6.62×10−4 g of h2?

Answers

N₂(g) + 3 H₂(g) = 2 NH₃(g)       molar mass N₂ = 28.0 g/mol
                                                                     NH₃ = 17.0 g/mol

14 g N₂ ---------------> 2 x 17 g NH₃
6.62 x 10⁻⁴ g --------> ?

Mass NH₃ = ( 6.62 x 10⁻⁴ ) x 2 x 17 / 14

Mass NH₃ = 0.022508 / 14

Mass NH₃ = 0.00160 g

number of moles = 0.00160 / 17 =  9.41 x 10⁻⁵ moles

1 mole ----------------------- 6.02 x 10²³ molecules
9.41 x 10⁻⁵ moles ----------  ?

molecules NH₃ =  ( 9.41 x 10⁻⁵ ) x ( 6.02 x 10²³ ) / 1

= 5.66 x 10¹⁹  molecules of NH₃

Photosynthesis transfers carbonfrom the nonliving environment to the living environment.
from the cell to the air.
from the water to the cell.
from the nucleus to the mitochondria.

Answers

Photosynthesis is the process in plants to make their food. This involves the use carbon dioxide to react with water and make sugar or glucose as the main product and oxygen as a by-product. I think the best answer would be the first statement.

Answer: Option A

Explanation:

Photosynthesis is a process that helps the plants to make food by the help of carbon dioxide from the atmosphere and water, nutrients from soil and converts it into glucose in the presence of sunlight.

Atmosphere is a non living component of environment where carbon dioxide is present and it is transferred to plants which is a living component of ecosystem.

What is the structure of beeswax that contains 16 carbon of carboxylic acid and 30 carbon of alcohol?

Answers

Answer:

Tricontanyl palmitate: CH₃-(CH₂)₂₉-O-CO-(CH₂)₁₄-CH₃

Explanation:

Beeswax is a tough natural wax which is produced by the worker honey bees. The beeswax is an ester of the long chain fatty acids and alcohols. One of the major components of beeswax is tricontanyl palmitate.

Tricontanyl palmitate is a wax ester that is composed of 16-carbon fatty acid and a 30-carbon alcohol, joined by an ester linkage.

The molecular structure of tricontanyl palmitate is:

CH₃-(CH₂)₂₉-O-CO-(CH₂)₁₄-CH₃
This is the answer hope this helps

Compute 3.5×4.48697. Round the answer appropriately. Express your answer numerically using the proper number of significant figures.

Answers

16 because the actual answer is 15.704395 then u round the .7 because it greater than 5 making it 16

Final answer:

The product of 3.5 and 4.48697 is 15.705395, which rounds to 16 when using the appropriate number of significant figures.

Explanation:

To find the product of 3.5 and 4.48697, you would simply multiply the two numbers together. This results in 15.705395.

However, the least number of significant digits in the numbers given is two (in the number 3.5). Therefore, we will round our answer to two significant figures. 15.705395 rounds to 16 when rounding appropriately to two significant figures as we count from the first non-zero digit, which is 1, then to the next digit which is 5.

How does a Geiger counter measure radiation levels

Answers

The Geiger counter measure radiation through the means of detecting alpha particles, beta particles and gamma rays. It uses an ionization effect produced by the Geiger-Muller tube as well. This is the most prominent tool used for radiation measurement.

Answer:

D- Radiation knocks electrons out of gas atoms, which allows the gas to conduct an electric current.

Which is the correct order of increasing standard molar entropy for the noble gases?He ≤ Ne ≤ Kr ≤ Ar

He ≤ Ne ≤ Ar ≤ Kr

Ne ≤ He ≤ Ar ≤ Kr

Kr ≤ Ar ≤ Ne ≤ He

Answers

Answer:

The correct order of increasing standard molar entropy for the noble gases is He ≤ Ne ≤ Ar ≤ Kr

Explanation:

Entropy is the measure of degree of disorderliness or randomness of a substance. Entropy increases with increasing number of electron present in an atom due to increased repulsive force of the electrons. Therefore, the standard entropy of a substance increases with an increase in their atomic masses.

For the given noble gases in this question, Helium (He) has the least atomic mass while Krypton (Kr) has the highest atomic mass.

Thus, the correct order of increasing standard molar entropy for the noble gases is He ≤ Ne ≤ Ar ≤ Kr
