Answer is: E- None of these.
NiCl₂ is nickel(II) chloride. Nickel chloride is salt.
KMnO₄ is p<span>otassium permanganate. P</span>otassium permanganate is salt.<span>
ZnSO</span>₃ is zinc(II) sulphite. Zinc sulphite is salt.<span>
SO</span>₂ is sulfur(IV) oxide. Sulpfur oxide is oxide. Oxidation number of sulfur is +4 and oxygen has oxidation number -2.
To solve this we use the
equation,
M1V1 = M2V2
<span>where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.</span>
4.5 ( V1 ) = 3.0 ( 500 mL )
V1 = 333.33 mL needed of the 4.5 M phosphoric acid
Hope this answers the question. Have a nice day.
Answer:
There will not be effect on the gas
Explanation:
I'm sure that it's correct answer
The layers of the Earth are the following:
outermost: crust
mantle
outter core
innermost: inner core
(that's 4 layers)
One can also divide them into smaller layers.
Molar Mass of 1 molecule of methane(CH4) = 12 + 4 = 16g/mol
That is, 16g if CH4 contain 1 mole molecule of it
= 6.022×10²³ molecules of CH4 which consists of 1 mole of C atoms and 4 moles of H atoms.
=> 4 g of CH4 contains 1/4 × 6.022×10²³ molecules
= 1.5055×10²³ molecules of CH4
= 1.5055×10²³ C atoms and 6.022×10²³ H atoms
Note: the question should be how many atoms of hydrogen and carbon and not molecules.
Hope it helps…
