How to balance barium and oxygen yield barium oxide

olga55 [171]

Barium : $Ba^{+2}$ with +2 being the charge
Oxygen : $O^{-2}$ with -2 being the charge

The given equation can be written as:
Ba + O = BaO

Since the sum charges of Barium and Oxygen equals 0, there is no need to add subscripts.

Both Ba and O appear on the left and right side of the equation once, so there is no need to add a coefficient.

Ba + O = BaO is balanced

Vitamin C, also known as ascorbic acid, is composed of 40.9 percent carbon, 4.6 percent hydrogen, and 54.5 percent oxygen. The m

Vladimir79 [104]

Answer:

Molecular formula is : C₆H₈O₆

Explanation:

40.9 % of C, 4.6 % of H, 54.5 % of O means that in 100 g of ascorbic acid, we have 40.9 g of C, 4.6 g of H and 54.5 g of O.

If 1 mol of ascorbic acid weighs 176 g, let's determine the rules of three to know the grams of each element:

100 g of compound has ___ 40.9 g C __ 4.6 g H ___ 54.5 g O

176 g compound mus have:

(176 . 40.9) / 100 = 72 g of C

(176 . 4.6) / 100 = 8 g of H

(176 . 54.5) / 100 = 96 g of O

If we convert the mass to moles:

72 g . 1 mol / 12 g = 6 C

8 g . 1 mol/ 1g = 8 H

96 g . 1mol / 16 g = 6 O

Molecular formula is : C₆H₈O₆

In conclussion, 1 mol of ascorbic acid has 6 moles of C, 8 moles of H and 6 moles of O

The characteristic odor of pineapple is due to ethyl butyrate, a compound containing carbon, hydrogen, and oxygen. combustion of

aev [14]

Answer: <em>C₃H₆O</em>

Explanation:

1) First, calculate the chemical composition, which you do using balance mass using the data given.

2) Data:

i) mass of ethyl butyrate: 2.22 mg

ii) mass of CO₂: 5.06 mg

iii) mass of H₂O: 2.06 mg

3) Solution

i) All the carbon in CO₂ produced was present in the ehtyl butyrate sample.

ii) The molar mass of CO₂ is 44.01 g/mol

iii) Use proportionality:

12.01 g C / 44.01 g CO₂ = x / 5.06 mg C ⇒ x = 1.38 mg C

iv) All the H in H₂O was present in the original sample of ethyl butyrate

v) The molar mass of H₂O is 18.015 g/mol

vi) Use proportionality

2.016 g H / 18.015 g H₂O = x / 2.06 mg H ⇒ x = 0.23 mg H

vii) Mass balance:

mass of O in the sample = mass of the sample - mass of H - mass of C

mass of O = 2.22 mg - 1.38 mg - 0.23 mg = 0.61 mg O.

viii) Composition:

C = 1.38 mg

H = 0.23 mg

O = 0.61 mg

Which in terms of composition is the same that:

C = 1.38 g

H = 0.23 g

O = 0.61 g

ix) Divide each by the molar atomic mass of the corresponding element, to obtain the number of moles:

C = 1.38 g / 12.01 g/mol = 0.115 mol

H = 0.23 g / 1.008 g/mol = 0.228 mol

O = 0.61 g / 16 g/mol = 0.0381 mol

x) Divide each by the least number of moles to obtain mole proportion

C = 0.115 / 0.0381 = 3.02 ≈ 3

H = 0.228 / 0.0381 = 1.98 ≈ 5.98 ≈ 6

O = 0.0381 / 0.0381 = 1

xi) Therefore the empirical formula searched is <em>C₃H₆O</em>.
