Explanation:

The balanced oxidation-reduction equation for the destruction of cyanate ion waste solution from gold-mining operations by treatment with hypochlorite ion in basic solution is:

OCN⁻(aq) + OCl⁻(aq) + 2OH⁻(aq) → CO₂⁻(aq) + N₂(g) + Cl⁻(aq) + H₂O(l)

In this reaction, the cyanate ion (OCN⁻) is oxidized to carbon dioxide (CO₂⁻) and nitrogen gas (N₂), while the hypochlorite ion (OCl⁻) is reduced to chloride ion (Cl⁻). The reaction takes place in basic solution, which provides the hydroxide ions (OH⁻) needed to neutralize the acidic H⁺ ions produced during the oxidation of the cyanate ion.

The reaction is exothermic, releasing heat energy as the products form. This reaction is an effective way to dispose of the cyanate ion waste generated by gold-mining operations, as it converts the hazardous waste into harmless gases and ions.

Explanation:

Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. What volume of hydrogen chloride would be produced by this reaction if 1.1 mL of methane were consumed?

Step 1: Write the balanced equation

CH₄(g) + 4 Cl₂(g) ⇒ 4 HCl(g) + CCl₄(g)

Step 2: Establish the appropriate volume ratio

For gases under the same conditions, the volume ratio is equal to the molar ratio. The molar ratio of CH₄ to HCl is 1:4.

Step 3: Calculate the volume of HCl produced from 1.1 mL of CH₄

1.1 mL CH₄ × 4 mL HCl/1 mL CH₄ = 4.4 mL HCl

Answer:

The resulting solution is basic.

Explanation:

The reaction that takes place is:

First we calculate the added moles of HNO₃ and KOH:

As there are more KOH moles than HNO₃, the resulting solution is basic.

The resulting solution is basic.

• It is known that KOH is a base and HNO3 is an acid, so when they mix they undergo a neutralization reaction.  

• The reaction between there will be,  

HNO3 + KOH ⇔ KNO3 + H2O

Based on the given information,

• The volume of HNO3 is 12.5 ml and the molarity is 0.280 M, and the volume of KOH is 5 ml and the molarity is 0.920 M.

Now 1 mole of HNO3 completely reacts with 1 mole of KOH,

The millimoles of HNO3 is,

\(= Molarity * Volume (in ml)\\= 0.280 * 12.5\\= 3.5 mmol\)

The millimoles of KOH is,

\(= Molarity * Volume (in ml)\\= 0.920 * 5.0\\= 4.6 mmol\)

Now it can be seen that 3.5 millimoles of HNO3 completely reacts with 3.5 millimoles of KOH. Now we are left with 4.6-3.5 = 1.1 mmol of KOH.

Thus, KOH is in excess amount present in the solution, and as it is basic in nature, therefore, the resultant solution would be basic in nature.

His hypothesis was that b) maggots come from eggs laid by flies.

Redii demonstrated that maggots do not spontaneously generate from rotting meat. He placed three jars containing rotting meat, each covered with different kinds of material. One jar was covered with a fine cloth, one with gauze, and one with cork.

Flies were observed landing on all three jars of meat, but after eight days, only the jar covered with the gauze had maggots on the meat. Redii observed the maggots on the meat and concluded that they had not spontaneously generated, but had come from the eggs of the flies that had landed on the meat.

From this, he concluded that maggots only form on meat that is exposed to the air, and not on meat that is sealed in a jar. This showed that it was not "spontaneous generation" that was creating the maggots, but rather that they were being laid by flies.

This is because he put meat in different locations and found that maggots only appeared where there were flies.

Answer:

Zn + HCl —> ZnCl2 + H2

Na + HCl —> NaCl + H2

Explanation:

The law of conservation of matter (mass) states that matter can neither be created nor destroyed during a chemical reaction, but can be transferred from one form to another.

A balanced chemical reaction support the law of conservation of matter (mass) as the total number of atoms on the right side equals the total number of atoms on the left side.

An unbalanced equation shows that atoms are either created or destroyed.

Conserdering the equations above, the following are unbalanced:

Zn + HCl —> ZnCl2 + H2

Na + HCl —> NaCl + H2

Therefore, it will not obey the law of conservation of mass.

Answer:

32.2 g of Na will produce 43.4 g of Na2O.

Explanation:

The balanced chemical equation for the reaction between sodium and oxygen shows that 4 moles of sodium react with 1 mole of oxygen to produce 2 moles of sodium oxide:

4Na(s) + O2(g) → 2Na2O(s)

To solve this problem, we can use the following steps:

Step 1: Convert the mass of Na given in the problem to moles using the molar mass of Na.

molar mass of Na = 23 g/mol

moles of Na = mass of Na / molar mass of Na

moles of Na = 32.2 g / 23 g/mol

moles of Na = 1.4 mol

Step 2: Use the mole ratio from the balanced chemical equation to determine the moles of Na2O produced.

From the balanced chemical equation, we can see that 4 moles of Na react to produce 2 moles of Na2O.

moles of Na2O = (moles of Na / 4) x 2

moles of Na2O = (1.4 mol / 4) x 2

moles of Na2O = 0.7 mol

Step 3: Convert the moles of Na2O to grams using the molar mass of Na2O.

molar mass of Na2O = 62 g/mol

mass of Na2O = moles of Na2O x molar mass of Na2O

mass of Na2O = 0.7 mol x 62 g/mol

mass of Na2O = 43.4 g

Therefore, 32.2 g of Na will produce 43.4 g of Na2O.

Approximately 166.67 mL of water needs to be evaporated from 250 mL of 1 M Ca(OH)2 to make it 3 M.

The relationship between the initial and final concentrations and volumes must be taken into account.

Given: Initial concentration \((C^1) = 1 M Initial volume (V^1) = 250 mL\)

\((C^2) = 3 M final concentration\)

We can use the equation:

\(C^1 * V^1 = C^2 * V^2\)

Where:

\(V^2\)is the final volume of the solution

Rearranging the equation to solve for V2:

\(V^2 = (C^1 * V^1) / C^2\)

Substituting the given values:

\(V^2 = (1 M * 250 mL) / 3 M\)

\(V^2 = 250 mL / 3\)

\(V^2\) ≈ \(83.33 mL\)

To find the amount of water that needs to be evaporated, we subtract the final volume from the initial volume:

Amount of water to be evaporated = \(V^1 - V^2\)

Amount of water to be evaporated = 250 mL - 83.33 mL

Amount of water to be evaporated ≈ 166.67 mL

Therefore, approximately 166.67 mL of water needs to be evaporated from 250 mL of 1 M Ca(OH)2 to make it 3 M.

The initial pressure exerted on the balloon was 8 atmospheres.

To find the initial pressure exerted on the balloon, we can use Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume when temperature is constant. The formula for Boyle's Law is P1V1 = P2V2, where P1 and V1 represent the initial pressure and volume, and P2 and V2 represent the final pressure and volume.

In this case, we are given that the initial volume (V1) is 14 L and the final volume (V2) is double the initial volume (2 x V1). We are also given that the final pressure (P2) is 4 atmospheres. We need to find the initial pressure (P1).

Using the formula P1V1 = P2V2 and plugging in the given values, we have:

P1 * 14 = 4 * (2 * 14)

P1 * 14 = 4 * 28

P1 * 14 = 112

To isolate P1, we divide both sides of the equation by 14:

P1 = 112 / 14

P1 = 8

It's important to note that the unit of pressure in this case is atmospheres, as stated in the question. If the pressure unit had been different, appropriate unit conversions would have been necessary.

In this case, since the ionization of HCl to H+ and Cl- ions decrease the pH of a solution as it gets more acidic due to the H+ ions; it is possible to infer that the presence of Cl- ions in the solution does not modify the pH of the solution because it is not able to react with water to form HCl and then undergo the aforementioned reaction because HCl is a strong acid so the ions are not able to undergo the reverse ionization.

In such a way, the answer will be C.
