Balance the following equation

C₂H₆O + O₂ → CO₂ + H₂O

Answer:

The solution is acidic.

Explanation:

To know which option is correct, we shall determine the pH of the solution. This can be obtained as follow:

Concentration of Hydrogen ion [H⁺] = 5.7×10¯⁷ M

pH =?

pH = –Log [H⁺]

pH = –Log 5.7×10¯⁷

pH = 6.2

pH scale reads as follow:

0 to 6.9 => Acidic

7 => Neutral

8 to 14 => Alkaline / basic

The pH of the solution (i.e 6.2) falls between 0 and 6.9 which indicates acidic.

Therefore, the solution is acidic.

what element is A??????

Answer:

82 g S

Explanation:

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 81.6 grams of sulfur are involved in this reaction.

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.

2 Fe + 3 S[tex]\rightarrow[/tex]Fe[tex]_2[/tex]S[tex]_3[/tex]

mass of iron = 95 grams

Molar mass of iron=55.8450 g/mol

number of moles of iron =Given mass÷ Molar mass of iron

number of moles of iron=95÷ 55.8

number of moles of iron=1.70 moles

The mole ratio between iron and sulfur is 2:3

moles of sulfur = (3/2) moles of iron

moles of sulfur = (3/2)×1.70

moles of sulfur=2.55 moles

Mass of sulfur= number of moles of sulfur× Molar mass of sulfur

                       =2.55× 32

                       =81.6g

Therefore, 81.6 grams of sulfur are involved in this reaction.

Explanation:

Answer:

60.5 L

Explanation:

If the gas temperature is constant, we can use Boyle's law:

P1V1 = P2V2

V2 = P1V1 / P2

P1 = 12.7 kPa

V1 = 40.0 L

P2 = 8.4 kPa

V2 = (12.7 kPa) (40.0 L) / (8.4 kPa) = 60.5 L

Answer:

C. oil and vinegar

Explanation:

A heterogeneous mixture is a mixture where the components are not uniform in composition, like oil and water. They don't mix. When you mix oil and vinegar, you have 2 layers because oil is less dense than vinegar.

Answer:

625.46 °C

Explanation:

We'll begin by converting 19 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

T(°C) = 19 °C

T(K) = 19 °C + 273

T(K) = 292 K

Next, we shall determine the Final temperature. This can be obtained as follow:

Initial volume (V₁) = 3.25 L

Initial temperature (T₁) = 292 K

Final volume (V₂) = 10 L

Final temperature (T₂) =?

V₁/T₁ = V₂/T₂

3.25 / 292 = 10 / T₂

Cross multiply

3.25 × T₂ = 292 × 10

3.25 × T₂ = 2920

Divide both side by 3.25

T₂ = 2920 / 3.25

T₂ = 898.46 K

Finally, we shall convert 898.46 K to celsius temperature. This can be obtained as follow:

T(°C) = T(K) – 273

T(K) = 898.46 K

T(°C) = 898.46 – 273

T(°C) = 625.46 °C

Therefore the final temperature of the gas is 625.46 °C

Answer:

94.9% yield

Explanation:

Percent yield = actual yield/theoretical yield x 100

So you will divide the actual yield (what they really produced) over the theoretical yield (what they expected to produce). This will give you a decimal answer, which you multiply by 100 to get a percent.

169g/178g = 0.949 x 100 = 94.9%
