Determine the number of moles 28.8 g Br2

Answers

well, you would just divide 28.8 by the molar mass of Br2 (the gram amount on the periodic table x2 because there's two of them)

Tin-126 has a half life of 100,000 years. How many years does it take toreduce 100 g of Tin-126 to 12.5 g?
100,000 years
200,000 years
50,000 years
300,000 years

Answers

Answer:

300,000 years

Explanation:

100g=0 years

50g=100,00 years

25g=200,00 years

12.5g=300,000 years

Which of the following might be an indicator of global warming?A. average increase in the temperatures near Earth's surface
B. a decrease in greenhouse gases
C. average decrease in the temperatures near Earth's surface
D. a decrease in carbon dioxide emissions

Answers

Answer: The correct answer is A. average increase in the temperatures near Earth's surface

Explanation: The reason this is correct is that global warming is it getting hotter, logically the temperatures near Earth's surface will be getting hotter as well. Hope this helps

Complete the first row in the table by filling in the missing information about a system at equilibrium.A:

Q < Keq

Q > Keq

Q = Keq

Answers

Answer:

A. Q = Keq

B. Equilibrium quantities of reactants and products

C. Q > Keq

D. System will shift toward reactants

E. Overabundance of reactants

F. System will shift toward products

Here are all the answers :)

Final answer:

To fill in the table about equilibrium, if Q < Keq the reaction will move right (produce more products), if Q > Keq it will move left (produce more reactants), and if Q = Keq the system is at equilibrium with no net change.

Explanation:

To complete the first row in the table about a system at equilibrium, we need to fill in the missing information based on the reaction quotient (Q) and the equilibrium constant (Keq).

For a system at equilibrium, not only is Q = Keq, but also the change in Gibb's free energy (ΔG) is zero. This relationship can be represented as 0 ΔG° + RT ln K at equilibrium.
