Answer:

A.

Explanation:

A toxic substance is a substance that can cause some harmful effects when a person is exposed to it. The sum of all adverse effects is called the toxicity of a substance. As higher is the toxicity, as dangerous is the substance. The effects can be observed in the mouth, the eyes, the skin, the tract respiratory, the brain, etc.

A substance or agent that can interfere with normal embryonic development is called teratogenic.

A substance or agent capable of causing or producing cancer in mammals is called carcinogenic.

The dose found to be lethal in 50 percent of a group of test animals when administered by the specified route is called LD50 (Lethal Dose 50).

What is the solubility of MgCO₃ in a solution that contains 0.080 M Mg²⁺ ions? (Ksp of MgCO₃ is 3.5 × 10⁻⁸)
Alchen [17]

Answer: 4.4 x 10^-7

Explanation:

The dissociation equation for this reaction is:

MgCO3 (s) → Mg+2 (aq) + CO3-2 (aq)

\text { So, } k_{s p}=(x+0.08) x (Here 0.08 >>> x )

\begin{aligned}\Rightarrow 3.5 \times 10^{-8} &=0.08 \times x \\\Rightarrow x &=\frac{3.5}{0.08} \times 10^{-8} \\&=4.37 \times 10^{-7} \\\Rightarrow x & \approx 4.4 \times 10^{-7} \mathrm{~M}\end{aligned}

So the solubility MgCO₃ in a solution that containing 0.080 M Mg²⁺ is 4.4 x 10^-7
