Answer:
The Celsius scale is in general use wherever metric units have become accepted, and it is used in scientific work everywhere. Kelvin temperature scale is the base unit of thermodynamic temperature measurement in the International System (SI) of measurement
Answer:
Explanation:
Before Hybridization => C: 1s²<u> ⇵</u> 2s²<u>⇵</u> 2p₋₁<u>↑</u> 2p₀<u>↑</u> 2p₊₁<u>∅</u>
After Hybridization => C: 1s² 2sp¹ 2sp¹ 2p₀¹2p₊₁¹ => 2 hybrid orbitals and 2 unhybridized p-orbitals at the n=2 energy level.
Answer:
molarity
Explanation:
Molarity is defined as the number of moles of solute in 1 liter of a solution while molality is defined as the mole of solute in 1 kg of solvent.
<em>If a solution prepared at 20 degrees celsius is heated to 88 degrees celsius, the molarity would change because the volume of a solution is temperature-dependent due to expansion or contraction. The molality, however, will not change for as long as the amount of the solvent remains unchanged due to the heating. </em>
Answer:
pH = 5.06, solution is acidic
Explanation:
pH = - log [H+]
we are given, [H+] as 8.7 x 10^-6M
Therefore;
pH = - log (8.7 x 10^-6 M)
= 5.06
pH = 5.06
But a solution with a pH of, 1-6 is acidic, while a pH of 7 is neutral and that of 8-14 is basic.
Thus; a pH of 5.06 is acidic
