8 0

Answer:

18.066 × 10²³ particles

Explanation:

Given data:

Number of moles = 3 moles

Number of particles = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For 3 moles of substance:

One mole = 6.022 × 10²³ particles

3 mol × 6.022 × 10²³ particles/ 1 mol = 18.066 × 10²³ particles

How do you determine the environmental impact of human activities?
coldgirl [10]

Answer:

Environment refers to everything that surrounds an individual and interacts between them. The factors that control the environment can be biotic and abiotic.

Humans have greatly affected the environment. Some of the ways in which the environment is affected by humans are as follows-

(1) Humans have constructed industries and factories that have released a huge amount of toxic gases into the atmosphere.

(2) These harmful gases have increased the earth's global temperature. As a result of which the global warming effect has increased.

(3) The waste materials eliminated from these industries mix with the rivers and streams and pollute the water. It degrades water quality.

(4) The fossil fuels are exhausted at a very high rate.

(5) The spilling of the oils in the oceans has affected the marine species drastically.

(6) Due to the extensive mining at different places, soil fertility has decreased considerably.

(7) Cutting down trees for settlement purposes and other infrastructures.

I need help with this one pls, ty! ASAP
LuckyWell [14K]

Answer:

Explanation:

1. A measure of how quickly velocity is changing is the acceleration

Acceleration is the rate of change of velocity with time. The rate at which a body is changing its velocity is known as the acceleration.

It is measured in the unit m/s²

2. Speed in a given direction is the velocity

Velocity is a vector quantity which measures the magnitude of motion in a specific direction. It is simply speed in a given direction.

When we say a motorcycle travels at the rate of 5m/s due east, we are describing the velocity of such body.

3. Force that resists moving one object against another is the friction

Friction is a force that opposes motion. It prevents a body from moving.

4. Measure of the pull of gravity on an object Weight

Weight is a measure of the amount of gravitational force on a body. It is mathematically expressed as;

         W = mg

W is the weight, m is the mass and g is the acceleration due to gravity

5 Tendency of an object to resist a change in motion is inertia

Inertia is the tendency of body to resist change in motion. It is the ability of a body to remain in a perpetual state of rest.

6 Size is the magnitude
