True


Explanation -

Burning fossil fuels releases gases and chemicals into the air. And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. Air pollution in the form of carbon dioxide and methane raises the earths temperature.

Hope this helps :)

Hope you have a great day !

Two chemist are trying to determine if their water sample is a mixture or pure substance. In their investigation they first filt
Effectus [21]

The correct answer is option B. Dirty water is a mixture of solid particles and liquid. It is both a mixture and pure substance.

The dirty water sample has both gravel and liquid water in it. After filtration the gravel is removed so the water sample looks clearer than before filtration. Liquid water is a pure substance because it is a compound that is made up of elements hydrogen and oxygen. Now the gravel is only physically combined with the liquid water, thus giving the water sample properties of a mixture. And like any mixture, gravel is physically separated through filtration from the liquid water.

Thus the water sample of the chemists is both a mixture and pure substance.

What is the atomic mass of an oxygen isotope that has 8 protons and 10 neutrons in its nucleus? 8 amu 10 amu 18 amu not enough i
Irina-Kira [14]

The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.

<h3>What is an atom?</h3>

An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.

The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.

The atomic mass can be given as:

\rm Atomic\;mass=Neutrons+Protons

The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:

\rm Atomic \;mass=10+8\;amu\\Atomic\;mass=18\;amu

The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.

antoniya [11.8K]

Answer:

8800  cm / s

Explanation:

There are 100 cm / m

  so:    88 m/s  * 100 cm / m =   8800 cm/s  

                     ( see how the 'm' cancels out and you are left with cm /s ?)
