The phase of matter where atoms lose their electrons is plasma. It requires quite a bit of heat, too.
First of all what is it asking for and second of all there is no picture of the observations, sorry can’t help with this question.
<h3><u>Answer;</u></h3>
a. CH3CO2H
<h3><u>Explanation;</u></h3>
- An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons. In other words an Arrhenius acid increases the concentration of H+ in aqueous solution.
- Acetic acid (CH3CO2) dissociates in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻). Therefore, it is an Arrhenius acid.
- The equation of dissociation;
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
Answer:
3.762 atm.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂)</em>
<em></em>
P₁ = 894.0 torr, V₁ = 534.0 mL,
P₂ = ??? torr, V₂ = 167.0 mL.
- Applying in the above equation
(P₁V₁) = (P₂V₂)
<em>∴ P₂ = (P₁V₁)/V₂</em> = (894.0 torr)(534.0 mL)/(167.0 mL) = <em>2859 torr.</em>
- To convert from torr to atm:
1.0 atm = 760.0 torr.
<em>∴ P₂ </em>= (2859 torr)(1.0 atm/760 torr) = <em>3.762 atm.</em>
