I believe the correct answer from the choices listed above is the third option. The <span>oxidation number of Nitrogen in HNO2 would be +3. It is calculated as follows:
1 + x + (-2)(2) = 0
x = +3
Hope this answers the question. Have a nice day.</span>
Answer:
.085 M .
Explanation:
3A(g) +4B(g) ⇋ 5C(g)
4 moles of B reacts with A to form 5 moles of C
.068 moles of B will reacts with A to form 5 x .068 / 4 moles of C
Moles of C formed
= 5 x .068 / 4
= .085 moles .
Answer:
in said reaction, there is a reaction by substitution, to form said compound. the product between both chemical compounds is propanonitrile.
Explanation:
cyanide is usually associated with potassium to form a salt, and as a product more stable chemical situations occur.
It is important to note that both products are very toxic.
Answer:
True
Explanation:
Yes this statement is true.
In a physical change, some of the physical properties of the substance may be altered and the chemical composition remains the same.
Answer:
b.CO2
d.CH3CH2CH2COOH (a fatty acid)
c.Cl-
a.C6H12O6
Explanation:
The cell membrane is permeable to gases and fatty acids, as they are non polar and small molecules. Those goes throught the cell membrane with no need of a canal or carrier.
The polar and big molecules needs a canal (as Cl-) or carrier (as C6H12O6) to get the cytoplasma.
