A chemical reaction happens if you mix together an acid and a base. The reaction is called neutralisation<span>, and a neutral solution is made if you add just the right amount of acid and base together.</span>
Answer:
207.24.
Explanation:
The mass numbers of the 4 isotopes are 82+ 122 = 204, 82 + 125 = 207,
82 + 124 = 206 and 208.
The approximate atomic mass is worked out by adding the products of their relative abundances and mass numbers:
0.014*204 + 0.221*207 + 0.241*206 + 0.524*208
= 207.24.
When light strikes a transparent material, most of the light passes through it it doesn't absorb or reflect it
Answers are:
2. It pushes on all objects that are on Earth’s surface.
3. It can be measured in atmospheres or kilopascals.
Barometric pressure (atmospheric pressure), is the pressure within the atmosphere of Earth
Atmospheric pressure decreases with increasing height, because there are fewer air molecules above a given object.
Barometer is an instrument used in meteorology to measure atmospheric pressure.
Atmospheric pressure (atm) is the force per unit area by the weight of air above that point.
Kilopascal (kPa) is a metric system pressure unit and equals to 1000 force of newton per square meter.
Atmospheric pressure results from molecular collisions of atmospheric gases.
