G to dkg is 1 place to the right, move the decimal point 1 place to the left
<span>225 g = 22.5 dkg
C is the answer</span>
Answer:
It contain double Bond.
Explanation:
To determine weather the bond is double or triple simply check the electron involved in mutual sharing of an electron if 2 electron takes parts it said to be double or if 3 it said to be triple.
Answer:
5.10
Explanation:
HCN ⇄ H⁺ + CN⁻
of HCN = 6.2 × 10⁻¹⁰ ;
molar solution of sodium cyanide [HCN] = 0.10M
∴ the pH of 0.10 molar solution of which contains the cyanide ion can be calculated as:
=
= 7.874 × 10⁻⁶
∴pH = -log {7.874 × 10⁻⁶}
= 5.10
On the first one it’s diffusion.
on the second on its false.
