If you start a chemical reaction with 5 atoms of helium, how many atoms will you have after?

Chemistry

Ivenika [448]2 years ago
3 0

Answer:

5 atoms

Explanation:

When a chemical reaction starts with 5 atoms of hydrogen, and the reaction goes into completion, it must give us 5 atoms of hydrogen.

This is in compliance with the law of conservation of mass which states that "in a chemical reaction, matter is neither created nor destroyed but converted from one form to another".

In chemical reactions, bonds are broken and new compounds are formed in the process. The same number of species at the start and end of the reaction must still be the same.

Identify and describe the three ways that mutations affect organisms?
Soloha48 [4]

Answer:

The ways that mutation can affect an organism include:

Changing the physical characteristics of the organism.

It can impact the way that the DNA is able to code the genetic information.

Also, mutation can lead to the death of an organism.

What is mutation?

Mutation simply means a change in the DNA sequence of an organism. It can result from DNA copying mistakes that were made during the cell division.

Mutation can affect an organism as it changes the phenotype of the organism. It can also impact the way that the DNA is able to code the genetic information and lead to the death of an organism.

An equilibrium mixture of CO, O2 and CO2 at a certain temperature contains 0.0010 M CO2 and 0.0100 M O2. At this temperature, Kc
Naya [18.7K]
The correct answer to this question is letter "B) 8.4 × 10-4 M."

2CO+O2<->2CO2

-x       -x        +x

It started as 2CO2 so +x, then it decomposed into 2CO and O2, so-x

2CO-oxidized, O2-Oxidized, 2CO2-reduced


the easiest way is to look at the equation, so if we have some reactant and no product 

A<->2C+D

-x    +2x +x
so if we had product concentration, and no reactant concentration 3A<-> C+D +3x -x-x <span>

A scientist studies the growth of plants in a laboratory. Which experimental procedure would provide evidence that
dusya [7]

The experimental procedure would provide evidence that plants need

nitrogen to grow is by

  • Identical plants are placed in two air-tight containers with sufficient exposure to sunlight.
  • One container has nitrogen gas, and the other has room air. The scientist measures plant growth

It is necessary to use identical plants during the experiment as plants have

different rates of nitrogen absorption from the soil. It should also be done in

air-tight containers called terrariums to prevent loss or contamination of the

gases with other elements/compounds.

The identical plants containing nitrogen and room air should both be

measured for the growth difference between them.

Suppose you decide to define your own temperature scale using the freezing point (13 degrees C) and boiling point (360 degrees C
podryga [215]
M.P of  oleic acid = 13 deg C 
<span>B.Pof  oleic acid = 360 deg C </span>



<span>(360 - 13) / 100 = 3.47 </span>
<span>So 1 deg O = 3.47 deg C </span>

<span>The scale do not start at 0 deg C, it starts at 13 deg C. So to convert deg C to deg O,
 subtract 13 then divide by 3.47 </span>

<span>deg O = (deg C - 13) / 3.47 </span>

<span>convert  O to C multiply by 3.47 then add 13 </span>

<span>deg C = (deg O x 3.47) + 13 </span>
