If there are 80 liters of argon gas in a piston and the piston expands the gas until its volume is 2000 liters with a pressure o
Mice21 [21]

Answer: The correct answer is A. 11.5 atm. The temperature is held constant at 293 K, therefore, we can use Boyle's Law to determine the initial pressure. Boyle's Law states that there is an inverse relationship between pressure and volume of gases. Therefore, as volume increases, the pressure will decrease and vice versa.

Further Explanation:

Boyle's Law can be mathematically expressed as:

P_{initial}V_{initial}\ = P_{final}V_{final}

In this problem, we are given the values:

P(initial) = ?

V(initial) = 80 L

P (final) = 0.46 atm

V (final) = 2000 L

Plugging in these values into the equation:

P_{initial}(80 \ L) = \ (0.46 \ atm)(2000 \ L)\\P_{initial} \ = \frac{(0.46 \ atm) \ (2000 \ L)}{80 \ L}\\P_{initial}\ = 11.5 atm\\

The initial pressure was 11.5 atm. Since the volume increased or expanded, the space where the gas particles move is bigger, so the frequency of collisions with the wall of the container and with other particles are effectively decreased. This, therefore, decreases the pressure from 11.5 to 0.46 atm.

You need to use a dilute hydrochloric acid solution in an experiment. However, the only bottle of hydrochloric acid in your lab’
mr_godi [17]

The pH of the diluted HCl solution is 1.3.

Explanation:

Given:

The concentrated HCl solution of 8.0 M. The 1.5 mL of 8.0 M HCl is diluted with water to 250 mL volume.

To find:

The pH of the diluted HCl solution.

Solution

  • The concentration of the HCl solution before dilution = M_1=8.0 M
  • The volume of the HCl solution taken for dilution = V_1=1.5 ml
  • The concentration of the HCl solution after dilution =M_2=?
  • The volume of the HCl solution after dilution = V_2=250 mL

Using the Dilution equation:

M_1V_1=M_2V_2\\8.0M\times 1.5ml=M_2\times 250 mL\\M_2=\frac{8.0M\times 1.5ml}{250 mL}=0.048 M

The concentration of diluted HCl solution = 0.048 M

HCl(aq)\rightarrow H^+(aq)+Cl^-(aq)

In the 1 M solution of HCl, there are 1 M of hydrogen ion, then the concentration of hydrogen ions in 0.048 M of HCl will be:

[H^+]=1\times 0.048M=0.048 M

The pH of the diluted HCl solution :

pH=-\log [H^+]\\=-\log [0.048M]=1.18 \approx 1.3

The pH of the diluted HCl solution is 1.3.

Element X reacts to form XO. It has the second smallest radius of its group. What is element X?
andriy [413]

Answer:

Li

Explanation:

Is the element of the first group and is the second smallest of its group. Even Magnesium is in the same situation, but if you compare the atomic radius of lithium and magnesium, the first one is smaller.

Barium definitely is incorrect because is the one that has the biggest radius of its group.

Beryllium is the first of its group so it can not fit the description.
