Who studied heredity and is known as the father of Genetics? (I am not surrre lol)

When you graph an inequality you used a closed dot or a open dot

Naddik [55]

For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution. For < and >, use an open circle to indicate the number itself is not part of the solution.

A beaker holding an unknown sample weighs 143.3502 g. The beaker weighs 132.2753 g. The unknown sample has a density of 2.18 g/m

dexar [7]

Answer:

5.08mL is the volume the sample occupies

Explanation:

Volume is defined as the mass of a substance in grams per mililiter that the substance occupies.

Subtracting the mass of the beaker + the sample - the mass of the sample we can obtain the mass of the sample:

143.3502g - 132.2753g = 11.0749g of the sample.

As its density is 2.18g/mL, the volume that the sample occupies is:

11.0749g * (1mL / 2.18g) =

<h3>5.08mL is the volume the sample occupies</h3>

Find the number of moles of water that can be formed if you have 170 mol of hydrogen gas and 80 mol of oxygen gas. Express your

Sav [38]

<u>Answer:</u> The amount of water that can be formed is 160 moles

<u>Explanation:</u>

We are given:

Moles of hydrogen gas = 170 moles

Moles of oxygen gas = 80 moles

The chemical equation for the reaction of hydrogen gas and oxygen gas follows:

$2H_2+O_2\rightarrow 2H_2O$

By Stoichiometry of the reaction:

1 mole of oxygen gas reacts with 2 moles of hydrogen gas

So, 80 moles of oxygen gas will react with = $\frac{2}{1}\times 80=160mol$ of hydrogen gas

As, given amount of hydrogen gas is more than the required amount. So, it is considered as an excess reagent.

Thus, oxygen gas is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 mole of oxygen gas produces 2 moles of water

So, 80 moles of oxygen gas will produce = $\frac{2}{1}\times 80=160moles$ of water

Hence, the amount of water that can be formed is 160 moles

Diazomethane, CH2N2, is used in the organic chemistry laboratory despite its danger because it produces very high yields and is

dexar [7]

Answer:

See picture below

Explanation:

You are not providing the starting compound. However, I found a similar question so, I will draw the product of this compound, and then, you follow the same procedure.

As the problem states, the diazomethane is often used in reaction with carboxilic acid. This kind of reaction will do an esterification reaction, and the final product will always result in an esther.

So, with the example I give you here, all you have to do is replace the OH in the carboxilic group of your initial compound, for the OCH₃ group.

See picture below.

Hope this helps
