In chemical equations, we usually state the state symbol behind each of the reactants and products. We use (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous solutions.


For example, here's an equation of sodium reacting with water:

2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)


As you can see, each behind each substance is the state symbol. This is how we presents physical states in chemical equations.

Ethanoic acid, CH3COOH, ionizes to form an ethanoate ion (CH3COO-) in aqueous solution. what else does it form? is it a monoprot
barxatty [35]

Ethanoic acid ionizes in aqueous solutions to form two ions which are CH_3COO^- and H^+

<h3>Ionization of ethanoic acid</h3>

Ethanoic acid goes by the chemical formula CH_3COOH.

In aqueous solutions, it ionizes as a monoprotic acid according to the following equation:

CH_3COOH ---- > CH_3COO^- + H^+

A monoprotic acid is an acid that is able to donate only a proton. Hence, ethanoic acid is said to be monoprotic because it ionizes in aqueous solutions to produce a single H^+

A photon of light with a frequency of 2.74 x 1014 Hz collides with an electron. How much energy
sesenic [268]

Answer:

1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron.

Explanation:

The energy of a photon is given by the equation:

E = h×ν

<em>Where E is energy of the photon in Joules.</em>

<em>h is Planck's constant (6.6262x10⁻³⁴Js)</em>

<em>And ν is frequency of the photon (In Hz = s⁻¹)</em>

<em />

The frequency of the photon is 2.74x10¹⁴Hz. That means its energy is:

E = 6.6262x10⁻³⁴Js × 2.74x10¹⁴s⁻¹

E =

<h3>1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron</h3>
