Write the balanced equation for the reaction of hydrogen chloride with sodium hydrogen carbonate to give sodium chloride, carbon
marusya05 [52]
These are the formulas of each compound mentioned:

1) Hydrogen chloride: HCl

2) Sodium hydrogen carbonate: NaHCO3 , this is also known as sodium bicarbonate. The number 3 to the right of O is a subscript.

3) Sodium chloride: NaCl

4) Carbon dioxide: CO2. This is also known as carbon anhydride. The number 2 to the right of O is a subscript.

5) Water: H2O. The number 2 to the right of H is a subscript.

The the chemical equation is:

HCl + NaHCO3 → NaCl + CO2 + H2O

Check the balance

element      left side      right side
H                 1+1 = 2        2
Cl                1                 1
Na               1                 1
C                 1                 1
O                 3                 2+1 = 3

Then, given that the number of each element on the left side is equal to the number of elements in the right side, the equation is balanced.

Which of the following types of electromagnetic radiation have higher frequencies than visible light and which have shorter freq
natta225 [31]

Answer:

Higher frequency than visible light -  <em>Ultraviolet light, X-rays, and Gamma rays</em>

Lower frequency than visible light - <em>Infrared radiation, microwaves, and Radio waves</em>

Explanation:

The frequencies of electromagnetic radiations vary according to their wavelengths. The relationship between the frequency and wavelength of the waves is expressed such that:

      λ = c/f, where λ = wavelength, c = speed of light, and f = frequency.

Thus, there is an inverse relationship between the wavelength and the frequency of electromagnetic waves.

The order of the electromagnetic waves based on their frequency from the lowest to the highest is <em>radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma-rays</em>

<u>Hence, electromagnetic waves with higher frequencies than visible light include ul</u><u><em>traviolet light, X-rays, and Gamma rays </em></u><u>while those with lower frequencies include </u><u><em>Infrared radiation, microwaves, and Radio waves. </em></u>
