What is a chemical bond?

Answers

Answer 1

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds

Mass = 22g Volume = 2cm3 What is the Density?

Answers

Answer:

11g/cm^3

Explanation:

The density of a substance can be found By

density= Mass/volume

From the question

mass = 22 g

volume = 2 cm³

22/2=11

We have the final answer as

11 g/cm³

Answer:

11g/cm^3

Explanation:

It is because the constant formula density is

Density=Mass/ Volume.

Therefore we have

Density=22g/2cm^3

Which is = 11g/cm^3

What is a buffer used for?

A. To limit the pH change in a solution
B. To prevent an acid from dissociating
C. To neutralize the pH of a solution
D. To prevent a salt from dissolving

Answers

A, a buffer is used to limit or to stop any change to the pH in a solution.

A buffer is primarily used to limit the pH change in a solution. Option A is correct.

A buffer is the solution which contains the weak acid and its conjugate base or weak base and its conjugate acid. It is designed to resist changes in pH when small amounts of acid or base are added to it.

When an acid or base is added to a buffer solution, the buffer components react with the added ions to minimize the impact on the solution's pH. If an acid is added, the buffer will react with the acid by accepting the H⁺ ions. If a base is added, the buffer will react with the base by donating H⁺ ions. In both cases, the buffer helps maintain the pH at a relatively stable level.

To prevent an acid from dissociating, is not accurate. A buffer does not prevent an acid from dissociating. In fact, the acid in a buffer solution is necessary to provide the conjugate base and maintain the buffer's pH buffering capacity.

To neutralize the pH of a solution, is also not accurate. A buffer does not neutralize the pH of a solution to a particular value. Instead, it resists significant changes in pH when small amounts of acid or base are added.

To prevent a salt from dissolving, is unrelated to the purpose of a buffer. A buffer is not used to prevent the dissolution of salts.

Hence, A. is the correct option.

H2SO4 + 2NaOH → Na2SO4 + 2H2O what volume of water vapor will be produced if you start with 71.5 g of sulfuric acid and excess of sodium hydroxide

Answers

Answer:

Explanation:

Find the molar mass of H2SO4

2H = 2 * 1 = 2

S = 1 * 32 =32

O4 = 4*16 = 64

total 98

Find the number of mols in 71.5 grams

mols = given mass / molar mass.

given mass = 71.5

molar mass = 98

mols = 71.5/98

mols = 0.7296 mols of H2SO4

Find the moles of H2O

From the Balanced equation, every mol of H2SO4 produces 2 moles of H2O

mols water = 2 * 0.7296

mols water = 1.4592

That's as far as I can take you. I have to know a great deal more to get the volume of H2O

-Your answer :βy Tobie

≛So why are pandas going extinct?

One of the main cause is due to the destruction of their own habitat

Since china is a country that is constantly growing their own homes are slowly being destroyed Since their habitats are becoming destroyed it forces them to live in small unhabitable area .

≛This leads to another problem.....

If they are forced to live in a small area there will be less food...

Since there is a shortage of food that will leave the panda's to slowly starve to death since pandas only eat bamboo they could never be able to live anywhere else....Another reason panda's are going extinct is because they are being hunted for their fur.

Answers

Answer:

Explanation:

potential energy is a kind of energy which rest or stays in one position

The objects rest on a position has a potential energy. The bow and arrow that was just pulled back but not yet released has energy has potential energy.

What is potential energy ?

The potential energy of an object is generated by virtue of its position at height above the surface. It is the stored form of energy when the object is at rest. Whereas, kinetic energy of an object is generated by virtue of its motion.

When the object starts to move with a speed, its potential energy starts to convert into kinetic energy. Both are dependent on the mass of the object. And these energies are directly proportional to the mass.

Here, the bow and arrow are not moving with a speed they just pulled and stay on a position, so they don't have a net kinetic energy but they possess a potential energy. Hence, option A is correct.
