Answer:

this is because aluminium is a non renewable source of material. the process to mine it is expensive. the process releases greenhouse gases which are harmful to the environment. it takes a long time to extract the aluminium. it is a way to help reduce waste products.

( this answer will only get you about 5 marks you need one more point in your answer. I just couldn't be bothered to think about another one.)

For each reaction, calculate how many moles of the barium product you will produce using stoichiometry and the balanced reaction
ankoles [38]

Answer:

Explanation:

given that

mass of Ba(NO3)2 = 1.40g

mass of NH2SO3H = 2.50 g

1)to determine the mole of  Ba(NO3)2

2) to determine the mass of all three product formed in the reaction

reaction

Ba(NO3)2 + 2NH2SO3H → Ba(NH2SO3)2 + 2HNO3

<u>Solution</u>

we calculate the molar mass of each species by using their atomic masses

BA = 137.33g/mol

N = 14g/mol

O= 16g/mol

H = 1g/mol

S = 32g/mol

calculation

Ba(NO3)2 = Ba + 2N + 6O

= 137.33 + 2X 14 + 6 X 16

= 261.33g/mol

NH2SO3H = N + 3H + S+ 3O

=14 + 3X1 + 32 + 3X 16

= 97g/mol

Ba(NH2SO3)2 = Ba + 2N + 4H +2S +6O

= 137.33 + 2 X 14 + 4 X1 + 2X32 + 6 X 16

= 329.33g/mol

HNO3 = H + n + 3O

= 1 + 14 + 3 X 16

= 63g/mol

Consider the balanced equation below.
wolverine [178]

Answer:

a) H2S:SO2 = 2:2 and O2:H2O = 3:2

Explanation:

  • 2H2S + 3O2 → 2SO2 + 2H2O

⇒ H2S:SO2 = 2 mol H2S / 2 mol SO2 ≡ 2 : 2

⇒ O2:H2O = 3 mol O2 / 2 mol H2O ≡ 3 : 2
