PV=nRT
So
NRT/P=V ...
SI units for pressure is pascals so 81.8KPA = 81.8 x 10^3 PA
SI units for temperature is kelvin so 15 degrees celsius = 15 +273 = 288K
(0.582 x 8.314 x 288)/81.8 x 10^3 = 0.017 m3 (cubic meters)
Answer:
Explanation:
Surface tension allows the coin to float on top of the water in this glass. The strong cohesion between the molecules makes it harder for objects on the surface of the water to sink.
Base + acid = salt + water
Example :
<span>HCl + NaOH = NaCl + H</span>₂<span>O
</span>
Answer A
hope this helps!
If I remember correctly it is water.
A
single oxygen has atomic number 8 that means the nuclei of all oxygen atoms
have eight protons. The number of minus-charged electron is two but the number
of electrons is 10. <span>To gain a minus two-charge ion, it
must have two more negative electrons than positive charged protons. With this,
the ion has 10 electrons, which give it a -2 net charge. </span>
