Answer:
The chemical name ends with “hydroxide.”
Explanation:
1- we write the name of the metal first and after that write the nonmetal:
Ex : NaOH ( sodium hydroxide)
2- any compound contains OH group is an ionic base and this group called hydroxide group
3- "Ous" ending is given in the ions with the lower oxidation.
4- " ic" ending is given in the ions with the higher oxidation.
<em>So, the correct answer is: The chemical name ends with “hydroxide.”.</em>
This happens in China.
Citizens of China are once constitutionally allowed to vote for their political leaders. China was once a sovereign state called People's Republic of China or PRC. It ended when it was replaced to a one-state party governed by the communist when the civil war ended in 1949.
In theory this should work.
If you take any shape of gold and put it in a container of water (the water being filled right to the top) and measure the overflow of water you get the volume of the object.
If you then measure its mass, you can get the density with this formula
Density = mass of object made of gold / the amount of water overflow
Given the crude methods Archimedes had at his disposal, any answer between 15 and 20 for the density would have been acceptable. If the object has any other impurities in it, the density would fall well below 19 or even 15 if there were enough impurities in it.
Explanation:
a man out of chronium 8 = 24.6 grams
mass of oxygen = 11.8 grams
mass of oxygen = 1.2 grams
total mass =24.6 + 11.8 + 1.2
=37.6
percent composition by mass of chromium
= 24.6/37.6 = 0.654
