Exothermic. The reaction of the two elements form the compound iron sulfide.
Answer:
Inside the human body they are known as glucose.
Explanation:
Your pancreas secretes insuline through the body in order to mantain a proper glucose levels through out the body. This is also what causes diabetes. If someone has diabetes this means that the pancreas is having trouble mantaining glucose through the body. This is why you should not consume sugar very often, then your body forgets how to create its own supply of glucose
Answer: 3.97 moles HCl
Explanation: Solution:
2.39x10²⁴ atoms HCl x 1 mole HCl /
6.022x10²³ atoms HCl
= 3.97 moles HCl
Answer:also confused ?
Explanation:cant see full answer
Mass of Al₂(SO₄)₃ : 4.822 g
<h3>Further explanation </h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2AlCl₃ + 3(NH₄)₂SO₄⇒Al₂(SO₄)₃+ 6NH₄Cl
MW AlCl₃ :133,34 g/mol
MW (NH₄)₂SO₄ : 132,14 g/mol
MW Al₂(SO₄)₃ : 342,15 g/mol
mol AlCl₃

mol (NH₄)₂SO₄

Limitng reactants (ratio mol : coefficient = the smaller)
AlCl₃ : (NH₄)₂SO₄ =

(NH₄)₂SO₄ ⇒ limiting reactants
So mol Al₂(SO₄)₃ from (NH₄)₂SO₄

mass Al₂(SO₄)₃

with 54.2% yield, the mass of Al₂(SO₄)₃
