Consider a balloon that has a volume V. It contains n moles of gas, it has an internal pressure of P, and its temperature is T.

If the balloon is heated to a temperature of 15.5T while it is placed under a high pressure of 15.5P, how does the volume of the balloon change?

Answer: The temperature will not change and will remain T.

Explanation: Accoding to ideal gas law:

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of gas

R = Gas constant = 0.0821 Latm/moleK

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

P_1= initial pressure

V_1= initial volume

T_1= initial temperature

P_2= final pressure

V_2= final volume

T_2= final temperature

Putting in the values:

\frac{PV}{T}=\frac{15.5PV_2}{15.5T}

T_2=T

Find [cu2+] in a solution saturated with cu4(oh)6(so4) if [oh − ] is fixed at 2.3 ✕ 10−6 m. note that cu4(oh)6(so4) gives 1 mol

</span>Cu_4(OH)_6(SO_4)
<span>
You have OH-  conc = </span>2.3 ✕ 10−6 m
From the formula, you can observe the ratio of Cu2+ to OH- is  4 : 6 = 2:3

So, for 2.3 ✕ 10−6 m OH-
[Cu2+] = \frac{2}{3} \times 2.3 \times 10^{-6}

= 1.53  \times 10^{-6} &#10;

Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0L. What temperature must be maintained
Morgarella [4.7K]
Given:

P = 123 kPa
V = 10.0 L
n = 0.500 moles
T = ?

Assume that the gas ideally, thus, we can use the ideal gas equation:

PV = nRT

where R = 0.0821 L atm/mol K

123 kPa * 1 atm/101.325 kPa * 10.0 L = 0.500 moles * 0.0821 Latm/molK * T

solve for T 

T = 295.72 K<span />

How many kJ to hear 0.700 pint of room temp water to boiling
irina1246 [14]
Use the equation Q = mCT.

Q is the amount of energy in joules.

m is the mass in grams.

C is the specific heat of water (4.184 J/g °C).

T is the change in temperature.

0.700 pints = 331.224 g of water

Q = (331.224 g)(4.184 J/g °C)(100° C - 30° C)

Q = 97,008.885 J

Divide by 1,000 to convert to kilojoules:

97.009 kJ

What is the hydrogen ion concentration of a substance with a pH of 4.5?​
FrozenT [24]

Answer:

The hydrogen ion concentration of the substance is 3.16*10⁻⁵ M

Explanation:

pH is a parameter used to measure the degree of acidity or alkalinity of a substance. The pH is calculated as the negative logarithm (base 10) of the concentration of hydronium ions [H₃O⁺] or hydrogen ions [H⁺].

pH= - log [H₃O⁺]= - log [H⁺]

Values ​​on the pH scale range from 0 to 14, where pH equal to 7 is neutral, below 7 is acidic and above 7 is basic.

In this case, pH= 4.5

So:

4.5= - log [H⁺]

Solving:

[ H⁺]= 10⁻⁴ ⁵

[H⁺]= 3.16*10⁻⁵ M

The hydrogen ion concentration of the substance is 3.16*10⁻⁵ M
