7 0
PH scale is used to determine how acidic, basic or neutral a solution is
pH can be calculated using the H₃O⁺
ph can be calculated as follows
pH = - log[ H₃O⁺]
[H₃O⁺] = 1 x 10⁻⁹
pH = - log [1 x 10⁻⁹]
 pH = 9
pH of solution is 9

If a gas sample has a pressure of 30.7 kpa at 0.00, by how many degrees celsius does the temperature have to increase to cause t
Otrada [13]
Pressure of the gas P1 = 30.7 kpa  
When it doubled P2 = 61.4 kpa  
Temperature T1 = 0 => T1 =. 0 + 273 =273 
Temperature T2 =? 
We have pressure temperature equation P1T1 = P2T2
 => T2 = P1T1 / P2 = (30.7 x 273) / 61.4 = 136.5 
 So the temperature for doubling the pressure is 136.5.

The _______ of a wave is a measure of the amount of energy it carries
Bumek [7]
The word that best fits is frequency. The sentence is The frequency of a wave is a measure of the amount of energy it carries. There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h * frequency. So, the answer is frequency.<span> Although you should know that wavelength is related to frequency and so it is also a measure of the amount of energy and it should also be other valid answer.</span>

A gas mixture consists of 60.0% Ar, 30.0% Ne, and 10.0% Kr by volume. If the pressure of this gas mixture is 80.0 kPa, what is t
Nat2105 [25]

Answer: The partial pressure of Argon , Neon and krypton are 48 kPa , 24 kPa and 8 kPa respectively.

Explanation:

According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as

p_A=x_A\times P_{total}

where, p_A = partial pressure of component A

x_A = mole fraction of A

P_{total} = total pressure

mole fraction of Ar = \frac{\text {Moles of Ar}}{\text {total moles}}=\frac{60.0}{60.0+30.0+10.0}=0.6

p_{Ar}=0.60\times 80.0kPa=48kPa

mole fraction of Ne = \frac{\text {Moles of Ne}}{\text {total moles}}=\frac{30.0}{60.0+30.0+10.0}=0.30

p_{Ne}=0.30\times 80.0kPa=24kPa

mole fraction of Kr = \frac{\text {Moles of Kr}}{\text {total moles}}=\frac{10.0}{60.0+30.0+10.0}=0.10

p_{Kr}=0.10\times 80.0kPa=8kPa
