Following are the Balanced Reactions,
Reaction 1:
(NH₄)₂CO₃ → <u>2</u> NH₄⁺ + CO3⁻²
Reaction 2:
PbI₂ → Pb⁺²<span> + <u>2</u> I</span>⁻¹
Reaction 3:
<span>(NH</span>₂<span>)</span>₃<span>PO</span>₄ → <span><u>3</u> NH</span>₄⁺ <span>+ PO</span>₄⁻³
Answer:
It's the first option. A distance between two similar points on a wave of light.
Explanation:
On a wavelength chart, where you measure the rate at which the light travels at its distance from the source. You have two points to compare to.
Answer:
The correct answer is - 4-nitroaniline.
Explanation:
It is given that all three solid compounds salicylic acid + 4-nitroaniline + naphthalene are equal in the ratio in the mixture and then 1 gram of this mixture is dissolved in the diethyl ether and run a drop of the solution on TLC plate. This plate shows three spots.
The salicylic acid and naphthalene would stay dissolved in the diethyl ether solution due to the 4-nitroaniline could be extracted by adding aqueous acid and involve in the aqueous layer and thus spot of 4-nitroaniline would be with largest Rf value.
Lead can cause
D.) brain damage
Explanation:
Lead poisoning is a sort of metal poisoning generated by lead in the body. The brain is the most sensitive. Symptoms may comprise abdominal pain, illness, headaches, irritability, thought problems, inability to have children, and tingling in the hands and feet. It causes almost 10% of the intelligent weakness of otherwise unknown cause also can result in behavioral problems. Some of the outcomes are strong. In severe cases, anemia, convulsions, coma, or death may occur.
