Explain what is the difference between molecule and atom?

Chemistry
1 answer:
Cerrena [4.2K]3 years ago
4 0

Answer:

Atoms: <em>they are tiny particles that are the basic building blocks of any substance. The atoms are themselves made up of even smaller particles-protons, neutrons and electrons. </em>

Molecules: <em>it is the smallest unit of matter, which can exist independently. A molecule is formed when two or more atoms combine together.</em>

You drop a rock weighing 23.2 g into a graduated cylinder that contains 55 mL. The level
snow_lady [41]

Answer:

<h2>3.31 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 23.2 g

volume = final volume of water - initial volume of water

volume = 62 - 55 = 7 mL

We have

density =  \frac{23.2}{7}  \\  = 3.314285

We have the final answer as

<h3>3.31 g/mL</h3>

Hope this helps you

what was the initial pressure of 14.8 mL of gas at 75.5 C , when it occupied a volume of 16.5 mL at 70.2 C and 101.3 kPa?
OLEGan [10]

Answer:

1038.96 kPa

Explanation:

We’ll use the ideal gas law; P1V1/T1 = P2V2/T2

P1*14.8/75.5 = 101.3*16.5/70.2

P1 = (101.3 * 16.5 * 75.5) / (70.2 *14.8)

P1 = 1038.96

A 75 Kg skateboarder is riding downhill, exerting 25 N. What is their acceleration?
Hunter-Best [27]

Answer:

<h3>The answer is 0.33 m/s²</h3>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

where

m is the mass

f is the force

a is the acceleration

From the question

f = 25 N

m = 75 kg

We have

a =  \frac{25}{75}   =  \frac{1}{3}  \\  = 0.333333333...

We have the final answer as

<h3>0.33 m/s²</h3>

Hope this helps you
