The theoretical yield of Cl2 from certain starting amounts of MnO2 and HCl was calculated as 60.25 g and 65.02 g, respectively.

If the percentage yield of Cl2 is 72%, what is its actual yield?

The actual yield is 43 g Cl₂.

The <em>limiting reactant was MnO₂</em> because it gave the smaller mass of Cl₂.

∴ The <em>theoretical yield</em> is 60.25 g Cl₂.

% yield = actual yield/theoretical yield × 100 %

Actual yield = theoretical yield × (% yield/100 %) = 60.25 g × (72 %/100%) = 43 g

What type of reaction occurs without the addition of heat?
maria [59]

The type of reaction that occurs without the addition of heat is called spontaneous reaction. That is option D.

<h3>What is spontaneous reaction?</h3>

Spontaneous reaction is defined as the reaction where by new substances are formed naturally without the addition of extra energy in the form of heat.

Therefore, the type of reaction that occurs without the addition of heat is called spontaneous reaction

What is the volume of an oxygen tank if it contains 12 moles of oxygen at 273 K under 75 kPa?
Zina [86]
Given:
n = 12 moles of oxygen
T = 273 K, temperature
p = 75 kPa, pressure

Use the ideal gas law, given by
pV=nRT \\ or \\  V= \frac{nRT}{p}
where
V = volume
R = 8.3145 J/(mol-K), the gas constant

Therefore,
V= \frac{(12\,mol)(8.3145\, \frac{J}{mol-K} )(273\,K)}{75 \times 10^{3} \, Pa}= 0.3632\,m^{3}

Answer: 0.363 m³

The danger from radon gas would most likely be greatest in:.
Semmy [17]

The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.

<h3>What is radon gas?</h3>

Radon is a naturally radioactive gas generated from different elements such as uranium or radium.

Radon is generated when these radioactive materials naturally decompose in the soils and/or rocks.

Radon is highly toxic and therefore this gas must be avoided to maintain healthy conditions in a home.

Represent the decomposition of aluminum oxide using the same number of atoms of molecules as are
pantera1 [17]

Answer:

Decomposition of aluminium oxide forms  aluminium atoms and  oxygen atoms.

Explanation:

<u>Decomposition reaction:</u>

When a single compound break down into two or more simpler products.

For example "AB" reactant undergoes decomposition to form "A" and "B" products.

The chemical reaction is as follows.

AB\rightarrow A+B

The given compound is aluminium oxide.

The decomposition reaction of aluminium oxide is a follows.

Al_{2}O_{3}\rightarrow Al+O_{2}

The balanced equation is as follows.

2Al_{2}O_{3}\rightarrow 4Al+3O_{2}

Therefore, Decomposition of aluminium oxide forms aluminium atoms and  oxygen atoms.
