Compare an electrically neutral atom of oxygen and an isotope of oxygen. in own words

Neutral implies that the amount of electrons  = amount of protons

so for oxygen, protons = 8

isotopes have equal number of protons but differ in number of neutrons , so that affect the mass since  :
protons + neutrons = atomic mass

Hope this helps

Explanation:

An isotope is defined as the specie which contains same number of protons but different number of neutrons.  

For example, ^{16}_{8}O and ^{17}_{8}O are isotopes.

In a neutral oxygen atom, there are 8 protons and 8 neutrons.  

As it is known that in a neutral atom the number of protons is equal to the number of electrons.  

This means that in a neutral oxygen atom there are also 8 electrons.

Whereas in ^{17}_{8}O is an isotope of oxygen atom whose atomic number is 8 and atomic mass is 17.

In ^{17}_{8}O, there are 8 protons and 9 neutrons.

Select True or False: A "gas" is a substance in which the molecules are separated on the average by distances that are large com
marta [7]

Answer:

True

Explanation:

The gaseous state is characterized in that the cohesion forces are usually null, in which the particles have their maximum mobility. The particles tend to occupy all the available volume, so their shape and volume are variable. The gaseous state is a dispersed state of matter, which means that the molecules are separated by distances much larger than the diameter of the gas molecules.

A container initially holds 1.24mol of hydrogen gas and has a volume of 27.8L. Hydrogen gas was added to the container, and the
Fantom [35]

Answer:

After increasing the volume, we have 1.81 moles of hydrogen gas in the container

Explanation:

Step 1: Data given

Number of moles hydrogen gas (H2) = 1.24 moles

Volume of hydrogen gas (H2° = 27.8 L

The final volume is increas to 40.6 L

Step 2: Calculate the new number of moles

V1/n1 = V2/n2

⇒with V1 = the initial volume = 27.8 L

⇒with n1 = the initial number of moles H2 = 1.24 moles

⇒with V2 = the final volume = 40.6 L

⇒with n2 = the new number of moles = TO BE DETERMINED

27.8L / 1.24 moles = 40.6 L / n2

n2 = 40.6 / (27.8/1.24)

n2= 1.81 moles

After increasing the volume, we have 1.81 moles of hydrogen gas in the container

An opening volumetric cylinder filled with water at volume 0.003m after period of
raketka [301]

Answer:

= - 303.975 Joules

Explanation:

Given that:

The volume of the cylinder = 0.003 m^3

Now, to liters:

The volume = 0.003 *1000 L

= 3 L

For an open cylinder, we mean the atmospheric pressure is at standard condition.

Thus, the workdone = -PΔV

= - 1 atm (3 L)

= - 3 L atm

1 L atm to Joules

= 101.325 Joules

Therefore;

=- 3* 101.325 Joules

= - 303.975 Joules
