Answer:

14.2 L H2S

Explanation:

Mole ratio

2 mol H2S:2 mol SO2

We are just looking for volume, so the required amount is the same as the produced amount as long as the mole ratio is balanced.

The balanced equation is: 2H2S + 3O2 → 2SO2 + 2H2O. Mole ratio 2 mol H2S:2 mol SO2.

Two factors can be used to identify stoichiometry problems:  the information provided in the problem and  he information that needs to be solved for, also known as the unknown.

The given and the unknown might both be reactants, could both be products, or could both be products with one of them acting as a reactant. Mole amounts can be used to express the substance quantities.

However, it is typical in a laboratory setting to calculate a substance's mass in grams to determine how much of it is present. A gaseous substance's volume can be used to express its quantity.

Therefore, The balanced equation is: 2H2S + 3O2 → 2SO2 + 2H2O. Mole ratio 2 mol H2S:2 mol SO2.

Answer:

HI and I-

Explanation:

Hello there!

In this case, according to the acid ionization of hydroiodic acid:

[tex]HI+H_2O\rightarrow I^-+H_3O^+[/tex]

Now, since the acid, HI, results in the conjugate base, I- and the base, H2O in the conjugate acid, H3O+, it is correct to assert that the acid-conjugate base pair is HI and I-

Best regards!

The acid-conjugate base pair in the reaction above is HI and I-. Details about conjugate base can be found below.

A conjugate base is the substance formed when an acid loses or donates its proton or hydrogen ion.

According to this question, the following reaction is given:

HI + H2O → H30+ + I-

The acid in this reaction is HI while the conjugate base is I-.

Answer:

The plateaus or horizontal lines on the graph represent the transition between states of the sample. The first plateau represents the melting (or transition from solid to liquid) and the second plateau represents boiling (or transition from liquid to gas).

Explanation:

Answer:

1.08827 x 10^3 g.

Explanation:

The equation for the reaction is:

2LiOH + CO2  ---->  Li2CO3 +  H2O

Using the molar masses:

CO2 = 12.011 + 2* 16 = 44.011.

LiOH = 6.94 + 1.008 + 16 = 23.948

S0 44.011 of CO2 reacts with  2*23.948 g of LiOH

1.00 *10^3 g CO2 reacts  with   2*23.948 * 1.00 *10^3 / 44.011

= 1088.27 g LiOH.

Explanation:

Question: Calculate the mass of magnesium chloride you would need to dissolve in 4dm³ of water to

make a 0.9g/dm³ solution.

Answer:

3.6 g

Explanation:

From the question,

Density of magnesium (D) = Mass of magnesium (m)/Volume of magnesium(V)

D = m/V............... Equation 1

Make m the subject of the equation

m = D×V............. Equation 2

Given: D = 0.9 g/dm³, v = 4 dm³

Substitute these values into equation 2

m = 0.9×4

m = 3.6 g.

Hence the mass of magnesium is 3.6 g.

Answer: The density of kerosene is [tex]2.7g/cm^3[/tex]

Explanation:

Density is defined as the mass contained per unit volume.

[tex]Density=\frac{mass}{Volume}[/tex]

Given : Mass of kerosene = mass of beaker with kerosene - mass of empty beaker = 60 g - 20 g = 40 g

Volume of kersone = [tex]15cm^3[/tex]

Putting in the values we get:

[tex]Density=\frac{40g}{15cm^3}[/tex]

[tex]Density=2.7g/cm^3[/tex]  

Thus the density of kerosene is [tex]2.7g/cm^3[/tex]

Answer:

Phosphorus

Answer:

[tex][Sr^{2+}]=5.66x10^{-4}M[/tex]

Explanation:

Hello there!

In this case, given the solubility equilibrium of strontium sulfate:

[tex]SrSO_4(s)\rightleftharpoons Sr^{2+}(aq)+SO_4^{2-}(aq)[/tex]

Whose equilibrium expression is:

[tex]Ksp=[Sr^{2+}][SO_4^{2-}][/tex]

In such a way, we can introduce the molar solubility, s, in the equation to obtain:

[tex]Ksp=s*s=s^2\\\\3.2x10^{-7}=s^2[/tex]

Then, we apply the square root to obtain:

[tex]s=\sqrt{3.2x10^{-7}}\\\\s=5.66x10^{-4}M[/tex]

Which is also the concentration of strontium ions:

[tex][Sr^{2+}]=5.66x10^{-4}M[/tex]
