What is the new concentration of a solution of CaSO3 if 10.0 mL of a 2.0 M CaSO3 solution is diluted to 100 ml?

Answers

Answer 1

Answer: The new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.

Explanation:

Given: [tex]V_{1}[/tex] = 10.0 mL,      [tex]M_{1}[/tex] = 2.0 M

[tex]V_{2}[/tex] = 100 mL,           [tex]M_{2}[/tex] = ?

Formula used to calculate the new concentration is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\10.0 mL \times 2.0 M = M_{2} \times 100 mL\\M_{2} = 0.2 M[/tex]

Thus, we can conclude that the new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.

A gas at 200 K occupies a volume of 350 ml. What temperature is needed to increase the volume
to 500 mL?

Answers

Answer: Temperature in constant pressure is 286 K

Explanation: If pressure remains constant, then V/T = constant.

V1 = 350 ml and T1 = 200 K and V2 = 500 ml.  V1/T1 = V2/T2

and T2 = T1· V2 / V1 = 200 K · 500 ml / 300 ml = 285,7 K

How many moles of hypomanganous acid, H3MnO4, are contained in 22.912 g?

Answers

Answer:

0.188mol

Explanation:

Using the formula as follows:

mole = mass/molar mass

Molar mass of hypomanganous acid, H3MnO4 = 1(3) + 55 + 16(4)

= 3 + 55 + 64

= 122g/mol

Mass of H3MnO4 is given as 22.912 g

Hence;

moles = 22.912 ÷ 122

number of moles = 0.188mol

What is the molarity when 25.0 g of the compound NaClO3 is placed in 85.0 mL of solution?

Answers

Answer: Molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.

Explanation:

Given: Mass = 25.0 g

Volume  = 85.0 mL (1 mL = 0.001 L) = 0.085 L

Molarity is the number of moles of a substance divided by volume in liter.

Hence, molarity of given solution is calculated as follows.

[tex]Molarity = \frac{mass}{Volume (in L)}[/tex]

Substitute the values into above formula as follows.

[tex]Molarity = \frac{mass}{volume (in L)}\\= \frac{25.0 g}{0.085 L}\\= 294.12 M[/tex]

Thus, we can conclude that molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.

what is the method use to separate sand and water​

Answers

Sand and water can be separated by any of the following methods:

1. Sedimentation and decantation: This method involves the mixture being kept undisturbed for some time. After some time, sand being heavier and insoluble in water, settles down at the bottom of container. Now, water is poured into another container to separate it from sand.

2. Filtration: This method involves the mixture being passed through a filter paper (a filter with very fine pores). Sand particles being larger in size are retained by the filter paper and get separated from water.

What is a molecule?

A molecule is a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.

6.02214076 × 10²³  molecules constitute 1 mole of NH₃

3.80 x 10²⁴ molecules constitutes of = 6.31 moles

1 mole of NH₃ = 17 gm

11.19 mole will be = 17 X 6.31

= 107.27 grams

Therefore the mass of a sample of NH₃ containing 3.80 x 10²⁴ molecules of NH₃ is 107.27 grams.

Round your answer to 1 decimal place.

Answers

Answer:

Explanation:

Using the ideal gas equation as follows:

PV = nRT

Where:

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

Based on the information provided in this question;

P = 1.6atm

n = 4.4 moles

R = 0.0821 L*atm/mol*K

T = 32.9°C = 32.9 + 273 = 305.9K

Answers

The question is incomplete, the complete question is;

Some carbonated beverages are made by forcing carbon dioxide gas into a beverage solution. When a bottle

of one kind of carbonated beverage is first opened, the beverage has a pH value of 3.

After the beverage bottle is left open for several hours, the hydronium ion concentration in the beverage

solution decreases to 1/1000 of the original concentration. Determine the new pH of the beverage solution.

Answer:

6

Explanation:

Recall that

pH= -log[H3O^+]

Hence, [H^+] when the drink was first opened;

3 = -log[H^3O+]

[H^+] = Antilog(-3)

[H30^+] = 1 * 10^-3

Since [H3O^+] decreases to 1/1000 times its original value;

New [H3O^+] =  1 * 10^-3 * 1/1000 = 1 * 10^-6

Hence,

New pH = -log[1 * 10^-6]

New pH = 6

At which position in its orbit was the Moon located during the 2015 supermoon total lunar eclipse?

Answers

On September 27, 2015, a rare total lunar eclipse of a supermoon occurred. A supermoon occurs when the entire lighted half of the Moon faces Earth (full Moon phase) and the Moon is at its closest point to Earth in its orbit.

The moon was located at position C in its orbit during the 2015 supermoon total lunar eclipse.

What is a supermoon lunar eclipse?

A supermoon can be described as a full moon that nearly coincides with perigee which is the closest that the Moon comes to the Earth in its elliptic orbit as results in a slightly larger-than-usual apparent size of the lunar disk can be viewed from the earth.

Perigee syzygy is the technical name of the Earth-Moon-Sun system or a full Moon around perigee. The association of the Moon with oceanic and crustal tides claims that the supermoon phenomenon can be associated with an increased risk of events such as volcanic eruptions and earthquakes, but no such connection has been found.

In the 21st century, there are 87 lunar eclipses in total, of which 6 are micro moons and 28 are supermoons. A supermoon lunar eclipse was seen in the September 2015 lunar eclipse.
