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 mass of deuterium (H-2) = 2

$m_{H-3}$ : is the mass of tritium (H-3) = 3

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

$\%_{H-2}$ : is the abundance percent of H-2 = 0.8%

$\%_{H-3}$ : is the abundance percent of H-3 = 0.2%

The average atomic mass is:

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

Changing all the percent values into decimal ones, we have:

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

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

A chemist measures the amount of iodine solid produced during an experiment. He finds that of iodine solid is produced. Calculat

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.

Answer: The number of moles of solid iodine produced is 0.0327 moles

Explanation:

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>1.2 Joule</h2>

solution,

Force=4 N

Distance=0.3 m

Now,

 $work = f \times d \\ \: \: \: \: \: \: \: \: \: \: \: = 4 \times 0.3 \\ \: \: \: \: \: \: \: \: \: \: \: = 1.2 \: joule$ 

hope this helps...

Good luck on your assignment....
