If 95 grams of Iron are needed to react with sulfur, how many grams of sulfur are involved in this reaction?
2 Fe + 3 S=Fe2S3

Answers

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.

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.

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.

A. It is counterproductive
B. Vinegar
C. Ammonia

Please give me Brainliest

A) Vinegar is an Acid solution while, Ammonia is a basic solution, so when they react they form a neutral solution,

Therefore this is a neutralization reaction

B) The lower the pH value of a solution, the more acidic it is, and vise versa for basic,

In the table Vinegar has the lowest pH value, of 3. Therefore Vinegar is the most acidic in the table

C) The higher the pH value of a solution, the more basic it is

In the table Ammonia has the highest pH value of 12. Therefore Ammonia is the most basic in the table

A sample of methane gas, CH4, occupies 3.25 L at temperature of 19.0 o C. If the pressure is held constant, what will be the temperature be if the volume expands to 10.00 L?

Answers

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
