100 POINTS+BRAINLIEST: How do you balance a chemical equation step by step? Please explain in simple language, give definitions to complex words and provide some rules to remember when balancing the equations. Use C3H8+O2—> H2O+CO2 as an example. THANKS SO MUCH!!!

Answers

Answer 1

Answer:

list all the elements.

you need to find a number to multiply both sides to get the same result.

example: I said on the left side: 5×O2 which is 10. on the right side I do the same to get 10.

In order to do this I said: 4×H2O which is 8 H2,and 4 O.

I then said 3×CO2 which gives 3 C and 6 O2. 6+4=10.

Now Oxygen(O) is balanced. Do the same for the rest of the elements.

Answer 2

Let's use

C3H8+O2—»H2O+CO2

Calculate atoms on both sides

On reactant side

C=3H=8O=2

On product

H=2O=3C=1

Now balance both sides by making atoms equal

The balanced one is

C3H8+5O2—»3H_2O+4CO_2

4P + 5O2 → P4O10 How many phosphorus (P) atoms are on each side of the equation? How many oxygen atoms are on each side?

Answers

Answer:

4 p and 10 O on both sides

Explanation:

on the reactant side you can see easily  that there are 4 P. With the oxygen on the reactant side you take the coefficient (5) times the subscript (2) which gives a total of 10 Oxygens.

On the product side there is a subscript of 4 next to the p, and a subscript of 10 next to the O

They are equal on both sides so you are done.

What is the significance of a gene?Immersive Reader

Answers

Explanation:

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. These small differences contribute to each person’s unique physical features.

Jenna notices that the speed of the wind has increased throughout the day. What is causing the faster wind?

The difference in air pressure has decreased.
The difference in air pressure has increased.
The direction of the wind has changed to the south.

Answers

The speed of the wind has increased throughout the day as there has been no precipitation.

What is precipitation?

Precipitation is a process in which vapor of liquid changes into small droplets.

In the day time temperature of the atmosphere is high as compare to the night, so rate of precipitation is low at the day time due to which speed of the wind has increased as compare to the night time.

Hence, option (a) is correct i.e. there is no precipitation.

What is an electromagnetic wave?

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
