Answer:
Explanation:
The expression for the root mean square speed is:
R is Gas constant having value = 8.314 J / K mol
M is the molar mass of gas
Molar mass of = 0.04599 kg/mol
Temperature = 400 K
Thus,
The three broad classes of elements are:
Metals
Metalloids
Nonmetals
Answer: For Number #1)
The solution above is an acidic solution
Kw= {H+}*{OH^-}
[OH^-] =Kw/[H+]
OH^-= 1.0*10^14/ 1.0*10^-4
=1.0*10^4
Answer:
<u>One Electron</u> is transferred.
Explanation:
The reaction is as follow,
<span> AgNO</span>₃<span> + Na </span>→ <span>NaNO</span>₃<span> + Ag
Reduction of Ag;
AgNO</span>₃ + 1 e⁻ → Ag
Oxidation State +1 0
Oxidation of Na;
Na → Na⁺ + 1 e⁻
Oxidation State 0 +1
Result:
Therefore, Sodium transfers one electron to silver to reduce it.
