What is the chemical equation

Chemistry
1 answer:
Serggg [28]3 years ago
5 0

Chemical equation is the symbolic representation of chemical reactions.

Explanation

Chemical reactions are known as the reaction where two or more molecules or compounds react with each other leading to formation of product compounds along with either release or absorption of energy.

The symbolic representation of the processes occurring in a chemical reaction is termed as chemical equation.

The symbolic representation includes the reactants, products, external energy type and quantity of external energy and also about release of energy if occurs.

So the reactants are usually written in the left side of the chemical equation whereas on the right the products are written.

Both the sides are linked by a single headed arrow mark.

Some both the sides are linked by double heated arrow mark indicating the equilibrium chemical reaction.

How could the survivors about starting a fire?
joja [24]

Answer:

The ancient Greeks believed that fire was one the four basic elements that composed all things in the universe. In the mythology of virtually every culture, fire is a sacred substance that gives life or power. Fire is not, in fact, a substance. When you gaze at the leaping flames of a campfire, you’re observing not an object, but a process – a chemical reaction. It’s the same chemical reaction that occurs when a cut apple left on the counter turns brown, when silver tarnishes or when an iron nail rusts.

That process is oxidation: combining oxygen with another substance. The defining difference between a fire and your half-eaten apple is speed: fire is an oxidation process that happens very fast, so that light, heat and sound are released — often with enough force and majesty to justify the ancients’ reverence.The sudden release of energy causes temperatures to rise, sometimes by thousands of degrees. And it also results in smoke, the toxic waste of fire’s leftovers.

fuel (something that will burn)

heat (enough to make the fuel burn)

and air (oxygen)

You have 100 grams of potassium fluoride (KF) .
laiz [17]

Answer:

Option C = 1.72 mol

Explanation:

Given data:

Mass of KF = 100 g

Moles of KF = ?

Solution:

First of all we have to calculate the molar mass of KF.

Molar mass of KF = 39.0983 g/mol + 18.998403 g/mol

Molar mass of KF = 58. 0967 g/mol

Formula:

Number of moles = mass/molar mass

Number of moles = 100 g/ 58.0967 g/mol

Number of moles = 1.72 mol

There are 360 degrees in a circle. How many arcminutes will be in 86% of a circle?
Leokris [45]

Answer:

There are 18572.9 arcminutes in 86% of a circle.

Explanation:

The degrees in 86% of a circle is:

degrees = \frac{86}{100}*360 = 309.6 ^{\circ}

Now, we need to find the number of arcminutes in 309.6°:

arcminute = \frac{59.99 arcminute}{1 degree}*309.6 degrees = 18572.9

Therefore, there are 18572.9 arcminutes in 86% of a circle.

I hope it helps you!
