Vinegar is aceti acid diluted in water.

The reaction of vinegar with sodium hydroxide is:

CH3COOH + NaOH ---> CH3COONa + H2O

That is an acid-base reaction.

The speed of reaction is proportional to the concentrations of the reactants.

Then, given thatn when you dilute the vinegar you decrease the concentration of CH3COOH, the rate of reaction will decrease.

Answer: decrease the rate of reaction.

A copper ore containing 4.3 wt% water, 10.3 wt% CuSO, and 85.3 wt% rock is fed to a staged counter current extractor at a rate o
Serga [27]

Answer:

6 stages

Explanation:

Given:

Copper ore contains:

4.3 wt% water

10.3 wt% CuSO₄

85.3 wt% rock

Feed rate = 11.7 tons per hour

solution produced is to be 10 wt% copper sulfate

90 wt% water

Now,

The CuSO₄ supplied through the feed = 10.3 wt% CuSO₄ × Feed rate

= 0.103 × 11.7

= 1.2051 tons per hour

also,

At each stage 2 tons of solution is collected

therefore,

The CuSO₄ collected in each stage

= weight of solution × 10 wt% copper sulfate

= 2 tons per hour × 0.1

= 0.2 tons per hour

also,

98% of the CuSO₄ is to be recovered

thus,

the amount of CuSO₄ to be recovered

= 0.98 × CuSO₄ supplied through the feed

= 0.98 × 1.2051 tons per hour

= 1.180998

Therefore,

The number of stages required = \frac{\textup{amount of CuSO₄ to be recovered }}{\textup{CuSO₄ collected in each stage }}

= \frac{\textup{1.180998}}{\textup{0.2}}

= 5.90499 ≈ 6 stages

Consider the following genotype Yy Ss Hh
Ilya [14]

From: Yy Ss Hh 8 different gametes can be formed

  • 5 Eye Color Genes = 243 genotypes
  • 10 Eye Color Genes= 59049 genotypes
  • 20 Eye Color Genes= 3,486,784,401 genotypes

This is further explained below.

<h3>What is a gamete?</h3>

Generally, Gametes are the cells of an organism that are responsible for reproduction. In certain contexts, they are also referred to as egg cells and sperm cells.

The popular word for female gametes is ova, whereas the common name for male gametes is sperm. Ovum and egg cells are other frequent names for female gametes.

Gametes are instances of haploid cells since they only contain a single copy of each chromosome. Haploid cells are described as having only one copy of each chromosome.

In conclusion, For 5 Eye Color Genes

3^n is implored hence

3^5=243 genotypes

Repeating said pattern e have

  • 10 Eye Color Genes= 59049 genotypes
  • 20 Eye Color Genes= 3,486,784,401 genotypes
