Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, what mass of NH[tex]_3[/tex] (g) produced is 11.23 g.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
N[tex]_2[/tex] + 3H[tex]_2[/tex] [tex]\rightarrow[/tex] 2NH[tex]_3[/tex]
moles of N[tex]_2[/tex]= given number of molecules/ 6.022×10²³
= 2 x 0²³/ 6.022×10²³
= 0.33 moles
moles of NH[tex]_3[/tex] produced= moles of N[tex]_2[/tex]×2
=0.66moles
mass of NH[tex]_3[/tex]= moles of NH[tex]_3[/tex]×Molar mass of NH[tex]_3[/tex]
= 0.66 × 17.03
=11.23 g
Therefore, what mass of NH[tex]_3[/tex] (g) produced is 11.23 g.

How is the glucose level in the blood maintained? Which body system, organs, and hormones are used and what do they do?
Answer:
Explanation:
Insulin is an hormone used to regulate blood glucose, as it helps to maintain a balance. It allows for transport of glucose to organs such as liver.
The process of glucose regulation is a complex process. When food is eating glucose is absorbed into the bloodstream this happen from the gut and it raises the blood glucose level this causes insulin(hormone) to be released from the pancreas so glucose can move inside the cells and be used.
As glucose moves inside the cells, the glucose level inside the bloodstream returns to normal and insulin release slows down.
Glucose which is the main energy source used by cells is allowed to be taken up by muscles, liver and fat (adipose tissue) and use as a source of energy so they can function properly.

Lithium and magnesium bromide react to produce lithium bromide and magnesium metal
Answer: [tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]
Explanation:
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
A more reactive element is one which can easily lose or gain electrons as compared to the other element.
The balanced chemical equation is:
[tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]
Here Lithium being more reactive than magnesium, it can easily displace magnesium from its salt solution and form lithium bromide and magneium in elemental form.

0.6 sample an unknown organic acid found in muscle cells is burned in air and found to contain 0.24g of carbon, 0.04g of hydrogen with the rest being oxygen. If the molecular weight of the substance is 90g/mol what is the emperical and molecular formula
Answer:
Molecular formula is, C₃H₆O₃
Empirical formula (with the lowest subscript) → CH₂O
Explanation:
We assume that the organic acid's mass is 0.6 g. We know that, in 0.6 g of compound we have 0.24 g of C and 0.04 g of H, then, we have
(0.6 - 0.24 - 0.04) = 0.32 g of O.
We determine each mol:
0.24 g /12 g/mol = 0.02 mol of C
0.04 g/ 1g/mol = 0.04 mol of H
0.32 g/ 16 g/mol = 0.02 mol of O
1 mol of acid weighs 90 g/mol.
In 0.6 g of acid, we have, (0.6 g / 90g/mol) = 0.0067 moles
Let's find out the formula with rules of three:
0.00667 mol of acid have 0.02 moles of C
1 mol of acid may have (0.02 /0.00667) = 3 mol of C
0.00667 mol of acid have 0.04 moles of H
1 mol of acid may have (0.04 /0.00667) = 6 mol of H
0.00667 mol of acid have 0.02 moles of O
1 mol of acid may have (0.02 /0.00667) = 3 mol of O
Molecular formula is, C₃H₆O₃
We confirm by the molar mass: 12g/mol . 3 + 6 . 1g/mol + 32g/mol . 3 = 90
Empirical formula (with the lowest subscript) → CH₂O
