6 Calculate the number of molecules in 8 g of oxygen.
Answer:
If you mean the number of atoms in 8g of oxygen, it's 3.011 x 10^23 atoms.
Explanation:
Convert the grams to moles. 8 grams of oxygen is 0.5 moles. Then multiply the number of moles by Avogadro's number: 6.022 x 10^23.

Chlorine has 7 valence electrons. With what group of elements will chlorine most readily bond?
Group 1
Group 2
Group 16
Group 18
Answer:
group 1
Explanation:
chlorine donate electron
Chlorine will more likely to form bonds with the elements of group 1 as it has 7 valence electrons.
Chlorine element:Chlorine is an element that is present in group 17. This family is also known as the Halogen family. The elements of this group will have seven electrons in their outermost shell. It has only one electron less to attain a stable noble electron configuration.
Thus, it will form bond more readily with Group 1 that has only one electron in its outermost shell.
Thus, correct option is a.

Consider the following balanced chemical reaction:
N2 + 3 H2 → 2 NH3
If you needed to produce 41.0 g of NH3, how many grams of H2 would you need?
Answer:
7.27 grams
Explanation:
Format= starting amount (g)·(1 mol/molar mass)·(amount of wanted/amount of starting)·(molar mass of wanted/1 mol)
[tex]41.0 x \frac{1 mol}{17.031}x\frac{3 H2}{2NH3} x\frac{2.016}{1 mol} =7.27[/tex]

Where glucose is broken down into smaller molecules to produce energy. The second part of the process takes place in the
Answer:
Mitochondria
Explanation:
Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.
The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of 3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.
In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.

Is there a solution for the impacts overfishing?
Answer:
The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.
Hope it will help you
