If 54.9 L of an ideal gas is cooled from 64 degrees C to 7 degrees C, what will the volume of the gas become?
sweet [91]

Answer:

Volume = 45.62L

Explanation:

Data;

V1 = 54.9L

T1 = 64°C = (64 + 273.15)k = 337.15K

T2 = 7°C = (7 + 273.15)k = 280.15K

V2 = ?

From Charles law,

The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant

V = KT, K = V / T = V1 / T1 = V2 / T2 = V3 / T3 =.........= Vn / Tn

(54.9 / 337.15) = (V2 / 280.15)

V2 = (54.9 * 280.15) / 337.15

V2 = 45.618L

V2 = 45.62L

Which substance, when dissolved in water, forms a solution that conducts an electric current?
Margarita [4]
Missing question: 
<span>(1) C2H5OH (3) C12H22O11
(2) C6H12O6 (4) CH3COOH.

Answer is: 4) CH</span>₃COOH, acetic acid.
In water, acetic acid dissociates on ions, so it can conduct electricity:
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
When we put electrodes (cathode and anode) in acetic acid solution, positive and negative ions migrate to electrodes.<span>
Negative acetate ions go to positive electrode and gives electrons to electrode.
<span>Positive hydrogen ions go to negative electrode and gain electrons.</span></span>

Answer:

Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. Least Common Multiple of 2 and 15 with GCF Formula The formula of LCM is LCM (a,b) = (a × b) / GCF (a,b).
