Chemistry
2 answers:
grandymaker [24]3 years ago

<u>Answer:</u>

<u>For 1:</u> The small 2 next to nitrogen atom is subscript.

<u>For 2:</u> The large 2 in front  of nitrogen atom is coefficient.

<u>For 3:</u> The correct answer is atoms.

<u>Explanation:</u>

Coefficients are defined as the numbers that are written in the front of atoms or molecules during a chemical reaction. They represent the number of moles of the substance present in a chemical reaction.

Subscript numbers are defined as the number of atoms of each element present in a compound.

Superscript numbers are defined as the charges of ions reacting in a chemical reaction.

  • <u>For 1:</u>

The chemical formula for nitrogen molecule given to us is N_2

Here, the small 2 next to nitrogen atom is subscript.

  • <u>For 2:</u>

The chemical formula for 2 moles of nitrogen molecule given to us is 2N_2

Here, the large 2 in front  of nitrogen atom is coefficient.

  • <u>For 3:</u>

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side. It can also be said that total number of individual atom on the reactant side is equal to the total number of individual atoms on the product side.

Hence, the correct answer is atoms.

1. Subscript is below
2. Coefficient large 2 indicates the number of moles
3. Atoms
1/2 O2 + H2 —> H2O
It’s the atoms that balance on each side
Notes that 1/2 is the coefficient and 2 is the subscript in H2 and H2O

4.Calculate the volume of 40g of Helium (He) at rtp.
Oksana_A [137]

Answer:

2.24dm³

Explanation:

Given parameters:

Mass of He = 40g

Unknown:

Volume of Helium  = ?

Solution:

To solve this problem, we convert the given mass to number of moles.

   Number of moles  = \frac{mass}{molar mass}  

   molar mass of He  = 4g/mol

  Number of moles  = \frac{4}{40}   = 0.1mole

So;

                  1 mole of gas at rtp occupies a volume of 22.4dm³

                0.1 mole of He will occupy a volume of 0.1 x 22.4 = 2.24dm³

By sprouting in the rainforest canopy, the strangler fig seedling is exposed to more
stiks02 [169]

Answer:

Waxy leaves protect the strangler fig from drying winds and sunlight that it is exposed to high in the canopy. Perhaps the most amazing part of this extraordinary tree is its flower. What we think of as the fruit is really a hollow, flower-bearing structure called a cyconia.

Before measuring the absorbance of a solution with the ocean optics spectrophotometer, it is important to run a blank sample of
Strike441 [17]
I think the most appropriate answer is: the solvent being used in the experiment
<span>To correct for any light absorption not originating from the solute you will need to calibrate the tools with a solution that most similar to the sample.
Blank covete or standard solution can be used, but it was not ideal. By using the solvent as calibration, you can remove the reading from the solvent so your result only comes from the sample.
