Explanation:

The net ionic equation of a reaction is obtained from the complete ionic equation after removing the spectator ions.

The balanced chemical equation for the reaction of sodium bicarbonate with acetic acid is shown below:

NaHCO_3(aq)+CH_3COOH(aq)->CH_3COONa(aq)+H_2O(l)+CO_2(g)

The complete ionic equation is:

Na^+(aq)+HCO_3^-(aq)+CH_3COO^-(aq)+H^+(aq)->CH_3COO^-(aq)+Na^+(aq)+H_2O(l)+CO_2(g)

The net ionic equation is:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)

Answer:The net ionic equation is shown below:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)

Question 22 A VHF television station assigned to channel transmits its signal using radio waves with a frequency of . Calculate
aleksklad [387]

The question is incomplete, here is the complete question:

A VHF television station assigned to channel transmits its signal using radio waves with a frequency of 66.0 MHz. Calculate the wavelength of the radio waves. Round your answer to 3 significant digits.

Answer: The wavelength of the radio waves is 4.54 m

<u>Explanation:</u>

To calculate the wavelength of light, we use the equation:

\lambda=\frac{c}{\nu}

where,

\lambda = wavelength of the light

c = speed of light = 3\times 10^8m/s

\nu = frequency of light = 66.0MHz=66.0\times 10^6s^{-1}

Putting the values in above equation, we get:

\lambda=\frac{3\times 10^8m/s}{66.0\times 10^{6}s^{-1}}=4.54m

Hence, the wavelength of the radio waves is 4.54 m

The water pressure on Mustafa as he dives is increasing at a rate of 0.9920.9920, point, 992 atmospheres (\text{atm})(atm)left p
pantera1 [17]

Based on the given scenario, the rate of increase in water pressure in atm/km is known to be 992 atm/km.

<h3>What is water pressure?</h3>

Pressure is known to be that kind of force that is known to often pushes water via pipes.

Note that Water pressure is a tool that is often used to know or identify the flow of water from any given tap. The amount of pressure at one's tap is said to be often dependent on how high the service tank or water tower is above one's home.

Therefore since 1 atm/m  = 1000 atm/km

Hence 0.992 atm/m  :

           = 0.992 x 1000

          = 992 atm/km.

Therefore, Based on the given scenario, the rate of increase in water pressure in atm/km is known to be 992 atm/km.

What is the molarity of 2.00 L of a solution that contains 14.6 g NaCl?
White raven [17]

Answer: The molarity of the solution is 0.125 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

moles of NaCl = \frac{\text {given mass}}{\text {Molar mass}}=\frac{14.6g}{58.5g/mol}=0.250mol

Now put all the given values in the formula of molality, we get

Molarity=\frac{0.250mol}{2.00L}=0.125M

Therefore, the molarity of the solution is 0.125 M
