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>
Answer:
Stacking storage sacks/ bags by interlocking, and placing heavier object on lower shelves.
Explanation:
Not sure what you meant exactly, but this is my best guess.
Okey so 1st find the moles of F2 which is :
n = 15/22.4 = 0.667mol
Then according to stoichiometric values, F2 and NaCl, they are to a ratio of 1 : 2
So take the twice value of the calculated moles.
Use the moles to find the mass using the equation :
m = n×M
Where m is the mass
n is moles
M is molar mass (of NaCl)
Therefore m = 1.334×57.5
(given the molar mass of Na 22gmol^-1 and CL 35.5gmol^-1)
m = 76.705g
Answer:
C
Explanation:
While some dilute acids are said to be weak, some are said to be strong. Now, the principal basis for this classification is based on the extent of ionization in water.
While strong acids ionize completely to give the maximum number of Oxonium ions, weak acids only ionize to an extent and thus do not give the full needed oxonium ions. Hence , we say they gave only a fraction and we term the ionization partial or incomplete.
Asa weak acid, nitrous acid is expected to ionize slightly and not completely. This makes it produce only a fraction of the expected oxonium ions in water
The answer is <span>(4) Silicon reacts with fluorine. The other three are just physical properties and are intensive (properties do not change, such as melting point, freezing point, color, etc.)
Hope this would work:)) </span>
