I believe the answer is C. The bonds in the compound magnesium sulfate is ionic and covalent. Magnesium sulfate is soluble in water. When the said compound is dissolved in water, it dissociates into magnesium ions and sulfate ions. However, the bonds that held together the sulfate ions is covalent.

Solid lithium hydroxide is used to "scrub" CO2 from the air inspacecraft and submarines; it reacts with the CO2 to produce lithi
ArbitrLikvidat [17]

Answer:

223 L

Explanation:

Step 1: Write the balanced equation.

2 LiOH + CO₂ = Li₂CO₃ + H₂O

Step 2: Calculate the moles corresponding to 440 g of LiOH

The molar mass of LiOH is 23.95 g/mol.

440 g × (1 mol/23.95 g) = 18.4 mol

Step 3: Calculate the moles of CO₂ that react with 18.4 moles of LiOH

The molar ratio of LiOH to CO₂ is 2:1. The reacting moles of CO₂ are 1/2 × 18.4 mol = 9.20 mol.

Step 4: Convert 20°C to Kelvin

K = °C + 273.15 = 20 + 273.15 = 293 K

Step 5: Convert 753 torr to atm

753 torr × (1 atm/760 torr) = 0.991 atm

Step 6: Calculate the volume of CO₂

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 9.20 mol × (0.0821 atm.L/mol.K) × 293 K / 0.991 atm

V = 223 L

The reaction 2CH4(g)⇌C2H2(g)+3H2(g) has an equilibrium constant of K = 0.154. If 6.30 mol of CH4, 4.20 mol of C2H2, and 11.15 mo
boyakko [2]

Answer:

C₂H₂ + 3H₂ ⟶ 2CH₄  

Explanation:

The initial concentrations are:

[CH₄] = 6.30 ÷ 6.00 =   1.05  mol·L⁻¹

[C₂H₂] = 4.20 ÷ 6.00 = 0.700 mol·L⁻¹

   [H₂] = 11.15 ÷  6.00 =  1.858 mol·L⁻¹

                2CH₄ ⇌ C₂H₂ + 3H₂

I/mol·L⁻¹:    1.05     0.700   1.858

Q = \dfrac{\text{[C$_{2}$H$_{2}$][H$_{2}$]}^{3}}{\text{[CH$_{4}$]}^{2}} = \dfrac{ 0.700\times 1.858^{3}}{1.05^{2}}= 4.07

Q > K

That means we have too many products.

The reaction will go to the left to get rid of the excess products.

C₂H₂ + 3H₂ ⟶ 2CH₄

5. When ortho-bromonitrobenzene is treated with NaOH at elevated temperature, only one product is formed. (a) Draw the product.
Mice21 [21]

Answer:

The product formed is orthonitrophenol

Explanation:

The compound orthonitrophenol is formed when ortho-bromonitrobenzene is treated with NaOH at elevated temperature.

The reaction leads to the formation of an intermediate stabilized by resonance. This intermediate can not be formed by the meta isomer because a resonance stabilized intermediate can not be formed and the product is not stabilized by intramolecular hydrogen bonding hence this reaction will not occur.
