The model suggests that, in the long run, the total child population will be 1.35% higher due to the transitory changes in fertility. Overall, climate change leads to less education and greater fertility, when compared to the world with a constant climate.


Hope this helps! :)

Hydrogen is 99% 1H, 0.8% 2H, and 0.2% 3H. Calculate its average atomic mass.
AlekseyPX

The average atomic mass of hydrogen (99% H-1, 0.8% H-2, and 0.2% H-3) is 1.012 amu.    

The average atomic mass of hydrogen can be calculated with the following equation:

A = m_{H-1}\%_{H-1} + m_{H-2}\%_{H-2} + m_{H-3}\%_{H-3}

Where:

m_{H-1}: is the mass of protium (H-1) = 1

m_{H-2}: is the <em>mass</em> of deuterium (H-2) = 2

m_{H-3}: is the <em>mass </em>of tritium (H-3) = 3

\%_{H-1}: is the abundance percent of H-1 = 99%

\%_{H-2}: is the <em>abundance percent</em> of H-2 = 0.8%

\%_{H-3}: is the <em>abundance percent</em> of H-3 = 0.2%

The average atomic mass is:

A = 1*99\% + 2*0.8\% + 3*0.2\%

Changing all the <u>percent values</u> into <u>decimal ones</u>, we have:

A = 0.99 + 2*0.008 + 3*0.002 = 1.012

Therefore, the average atomic mass of hydrogen is 1.012 amu.

Dimas [21]

The question is incomplete, the complete question is:

A chemist measures the amount of iodine solid produced during an experiment. He finds that 8.31 g of iodine solid is produced. Calculate the number of moles of iodine solid produced. Round your answer to the correct number of significant digits.

<u>Answer: </u>The number of moles of solid iodine produced is 0.0327 moles

<u>Explanation:</u>

The number of moles is defined as the ratio of the mass of a substance to its molar mass.  The equation used is:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} ......(1)

Given mass of solid iodine = 8.31 g

Molar mass of solid iodine = 253.8089 g/mol

Plugging values in equation 1:

\text{Moles of solid iodine}=\frac{8.31g}{253.8089g/mol}=0.0327mol

Hence, the number of moles of solid iodine produced is 0.0327 moles

Calculate the work done when a force of 4 N pulls a box along the floor for a distance of 0.3 m.
Yuki888 [10]

Answer:

<h2><em>1</em><em>.</em><em>2</em><em> </em><em>Joule</em></h2>

<em>sol</em><em>ution</em><em>,</em>
