The following gases were bubbled through water, which of the gases is most likely to dissolve and why?
a. CO2
b. CH4
C.PH
d. N2

Answers

Solubility refers to the ability of substances to dissolve in a solvent. Of the gases listed here, that which would most likely dissolve in water is;

a. CO2

Carbon dioxide is a gas that has a very high solubility in water. When bubbled through water, 99% of the gas dissolves while 1% of the gas comes off as carbonic acid.

The solubility of carbon dioxide increases with an increase in pressure and decreases with an increase in temperature.

Therefore, option A is correct.

Consider a galvanic cell with a beaker of sulfuric acid and a beaker of nitric acid. The sulfuric acid beaker contains a strip of tin, and the nitric acid cell contains a strip of platinum. A wire runs between the strips. The reaction that occurs is as follows:

3Sn(s) + 2NO3–(aq) + 8H+(aq) → 3Sn2+(aq) + 2NO(g) + 4H2O(l)

In three to five sentences, list which electrode is the anode and which is the cathode and the half reactions that occur at each electrode.

Answers

I wrote, The platinum electrode is the cathode in this reaction. The tin electrode is the anode in this reaction. In the half reactions that occur the nitrate is reduced to nitric oxide(NO) while the tin electrode is oxidized to Sn2+.

Oxidation occurs at the tin half cell(anode) while reduction occurs at the nitrate half cell(cathode).

A galvanic cell refers to a cell that produces electrical energy spontaneously by redox reaction. Oxidation occurs at the anode while reduction occurs at the cathode in a galvanic cell.

The oxidation half equation at the anode occurs as follows;

3Sn(s) → 3Sn^2+(aq) + 6e

The reduction half equation that occurs at the cathode is;

2NO3–(aq) + 8H+(aq) + 6e→  2NO(g) + 4H2O(l)

We can see that electron loss occurs at the cathode while electron gain occurs at the anode as we can see in the equations above.

Butene gas C4H8 has a molar mass of 56.1gmol. If it occupies 3000. mL of space at 1000. K and 760. torr, how much butene gas (in grams) is present

Answers

Answer:

2.05g

Explanation:

The weight of butane gas present in the system with the specified temperature and pressure is 2.05 g. We can use ideal gas law here.

What is ideal gas law?

Ideal gas law states the relation between temperature, pressure and volume  and mathematically written as below:

PV = nRT

Here, P and V be the pressure and volume and n be the no.of moles and R be the universal  gas constant. T is the absolute temperature in kelvin.

The system have a volume of 3000 mL or 3 L and pressure of 760 torr and temperature of 1000 K. The no. of moles n is the ratio of taken weight to the molar mass. R has the value 62.36 L torr/(K mol)

Apply these values into ideal gas law as given below:

(3 L × 760 torr)  = (w/56.1 g/mol) × 62.36 L torr/(K mol) × 1000 K. From this,

[tex]2280 \textup{ torr L} = \frac{w}{56.1 g/mol} \times 62360 \textup{ L torr/mol}[/tex]

[tex]w = \frac{2280\textup{ torr L}\times 56.1\textup{ g/mol}}{62360 \textup{ L torr/mol}} =2.05 g[/tex]

Therefore, the amount of butane gas for the given system is 2.05 g.

Answers

The major product is 3-methyl-2-pentene and the minor product is 2-ethyl-1-butene.

The alkyl halide shown is 3-bromo-3-methyl pentane. We can see that it is a tertiary alkyl halide. The proportion of products formed during the reaction are determined by Markovnikov rule.

The two products of this reaction are; 3-methyl-2-pentene and 2-ethyl-1-butene. The major product is 3-methyl-2-pentene because it is formed from a more stable carbocation intermediate.  2-ethyl-1-butene is the minor product.

3. How many grams of magnesium ion are in 155.0 grams of Mg3P2?

Answers

Answer:

83.82 g of magnesium ions.

Explanation:

We want to determine the mass of magnesium ions in 155.0 grams of magnesium phosphide (Mg₃P₂).

We can convert from grams of Mg₃P₂ to moles of Mg₃P₂, moles of Mg₃P₂ to moles of Mg, and moles of Mg to grams of Mg.

Find the molecular weight (molar mass) of magnesium phosphide:

[tex]\displaystyle \begin{aligned}\text{MW}_\text{Mg$_3$P$_2$} &= \left(3(24.31)+2(30.97)\right) \text{ g/mol} \\ \\ &= (72.93 + 61.94) \text{ g/mol} \\ \\ &= 134.87 \text{ g/mol}\end{aligned}[/tex]

The molecular weight of magnesium is 24.31 g/mol*.

From the chemical formula, we can see that there are three moles of magnesium for every one mole of magnesium phosphide.

Hence, multiply initial amount with known ratios:

[tex]\displaystyle \begin{aligned} &155.0 \text{ g Mg$_3$P$_2$} \cdot \frac{1 \text{ mol Mg$_3$P$_2$}}{134.87\text{ g/mol}} \cdot \frac{3\text{ mol [Mg$^{2+}$]}}{1 \text{ mol Mg$_3$P$_2$}}\cdot \frac{24.31 \text{ g [Mg$^{2+}$]}}{1 \text{ mol [Mg$^{2+}$]}}\\ \\ & = 83.82 \text{ g [Mg$^{2+}$]}\end{aligned}[/tex]

In conclusion, there are 83.82 grams of magnesium ions in 155.0 grams of magnesium phosphide.

*Because the magnesium ions in magnesium phosphide have two less electrons, its molecular weight will indeed be lower. However, due to the extremely small size of an electron (1/2000th of a proton), the difference in mass is insignificant.

Write a net ionic equation for the formation of calcium oxalate that results when a solution of calcium bromide is mixed with a solution of sodium oxalate.

Answers

The net ionic equation is; Ca^2+(aq) +  C2O4^2-(aq) -----> CaC2O4(s).

First of all we must write the molecular reaction equation;

CaBr2(aq) + Na2C2O4(aq) -------> CaC2O4(s) + 2NaBr(aq)

Then we write the complete ionic equation as follows;

Ca^2+(aq) + 2Br^-(aq) + 2Na^+(aq) + C2O4^2-(aq) -----> CaC2O4(s) +  2Na^+(aq) +  2Br^-(aq)

We can now write the net ionic equation as follows;

Ca^2+(aq) +  C2O4^2-(aq) -----> CaC2O4(s)

The net ionic equation eliminates the spectator ions and only shows the ions that underwent change in the reaction.
