malfutka [58]

Answer:

Explanation:

Atomic number of Ne is 10.

Electronic configuration of Ne:

$1s^2 2s^2 2p^6$

Octet of Ne is complete . Element having complete octet are stable and behave ideal gas.

$N_2$ and $CH_4$ are reactive and hence, does not behave as ideal gas.

In a 71.4 g sample of nahco 3 3 , how many grams of sodium are present?

sweet [91]

There are 19.5 g Na in 71.4 g NaHCO₃

Calculate the <em>molecular mass of NaHCO₃</em>.

1 Na = 1 × 22.99 u = 22.99 u

1 H = 1 × 1.008 u = 1.008 u

1 C = 1 × 12.01 u = 12.01 u

3 O = 3 × 16.00 u = <u>48.00 u </u>

TOTAL = 84.008 u

So, there are 22.99 g of Na in 84.008 g NaHCO₃.

∴ Mass of Na = 71.4 g NaHCO₃ × (22.99 g Na/84.008 g NaHCO₃) = 19.5 g Na
