How many atoms of hydrogen exist in Na + H2O → NaOH + H2

Kazeer [188]

If you're talking about in an actual sample, you'd need more data like how many moles you have of the reactant or product.

Just in terms of the equation : there are two from the water in the reactant (left) side, and one from the sodium hydroxide and two for the hydrogen gas on the product (right) side, so 2+1+2=5 atoms of hydrogen.

What is the wavelength of electromagnetic radiation with a frequency of 9.23 × 10^-7 Hz?

stich3 [128]

3.25 x 10¹⁴m

Explanation:

Given parameters:

Frequency of the radiation = 9.23 x 10⁻⁷hz

Unknown:

Wavelength of the radiation = ?

Solution:

The velocity of electromagnetic radiation is the same as that of the speed of light in vacuums.

Velocity = frequency x wavelength.

Velocity = 3 x 10⁸m/s

Since the unknown is wavelength, we factor it out:

Wavelength = $\frac{Velocity }{frequency}$

Wavelength = $\frac{x}{y}$ $\frac{ 3 x 10^{8} }{9.23 x 10^{-7} }$

= 3.25 x 10¹⁴m

Identify the bronsted-lowry acid and the bronsted-lowry base in this reaction on the left side of each of the following equation

Dahasolnce [82]

<u>Answer:</u> $NH_4^+$ is an acid, $CN^-$ is a base, $NH_3$ is conjugate base and $HCN$ is conjugate acid

<u>Explanation:</u>

According to Bronsted and Lowry's theory:

An acid is defined as a proton donor while a base is defined as a proton acceptor.

In a chemical reaction, an acid loses a proton to form a conjugate base while a base accepts a proton to form conjugate acid.

For the given chemical reaction:

$NH_4^+(aq)+CN^-(aq)\rightleftharpoons HCN(aq)+NH_3(aq)$

$NH_4^+$ is losing a proton thus it is an acid to form $NH_3$ which is its conjugate base

$CN^-$ is gaining a proton thus it is a base to form $HCN$ which is its conjugate acid

Hence, $NH_4^+$ is an acid, $CN^-$ is a base, $NH_3$ is conjugate base and $HCN$ is conjugate acid
