Answer:

Coral reefs are home to more species of fish and marine invertebrates than any other habitat in the world. Coral reefs protect beaches and shorelines from the impact of waves. Without coral reefs, beaches and shorelines can be severely damaged or washed away. Corals also produce unique chemicals that have potential uses in medicine.

The pipet used for transferring the pickle juice to the flask was dirty and consequentially some of the pickle juice stuck to th

lesya [120]

Explanation:

Since, some of the given sample is stuck inside and behind the pipet. Hence, there will occur a decrease in the percent of acetic acid.

This is because a decrease in concentration of the acid will also lead to a decrease in the amount of sample taken for the estimation. Since. lesser is the amount or concentration present lesser will be its analyte concentration.

For example, we took 10 mg of a pickel sample but 3 mg of the sample remain stuck in the pipet. This means we actually titrating a sample less than 10 mg.

Therefore, the analyte concentration in the pickel will also be less.

What is the mole ratio of D to A in the generic chemical reaction 3A + B C + 4D

ehidna [41]

Answer:- Mole ratio of D to A is 4:3.

Explanations:- Mole ratio for a chemical reaction is the ratio of the coefficients.

The given generic chemical reaction is:

$3A+B\rightarrow C+4D$

The numbers written in front of each chemical species in the chemical reaction are their moles. For the given generic chemical reaction the coefficient of A is 3 and that of B is 1. So, the mole ratio of A to B is 3:1.

Similarly if we want to write the mole ratio of C to D then it is 1:4.

We are asked to write the mole ratio of D to A. So, like the other ratios, the mole ratio of D to A is 4:3 as the coefficient of D is 4 and A is 3.
