pH depend on the temperature. At room temperature pH scale is between 0 to 14. pH of neutral solution is 7. pH meter is the only instrument to measure the pH of an unknown solution.

What is pH?

pH is a measurement of amount of hydronium ion H₃O⁺ in a given sample. More the value of hydronium ion concentration, more will be the solution acidic.

On subtracting pH from 14, we get pOH which measures the concentration of hydroxide ion in a given solution.

pH meter is used to measure the pH of an unknown solution. A glass probe is attached to pH meters, that measure the concentration of hydrogen ion in unknown solution. Take the unknown solution in the beaker and then put the washed, clean glass probe in the solution. Now wait for a second to take the reading.

37.2 moles of hydrogen gas would have what mass?
Your answer

Answers

Answer:

74.99g

Explanation:

Mass of a substance can be calculated by using the formula;

mole = mass ÷ molar mass

mass = molar mass × mole

According to this question, 37.2 moles of hydrogen gas is given.

Molar mass of hydrogen gas (H2) = 1.008(2) = 2.016g/mol

mass = 2.016 × 37.2

Mass of H2 = 74.995

Mass = 74.99g

320 moles O₂

Explanation:

S₈ +O₂ → SO₈

The balanced equation is:

S₈ + 32O₂ → 8SO₈

Now we can convert moles of SO₈ (the product) into moles of each reactant, using the stoichiometric coefficients of the balanced reaction:

80 mol SO₈ * [tex]\frac{1molS_8}{8molSO_8}[/tex] = 10 mol S₈80 mol SO₈ * [tex]\frac{32molO_2}{8molSO_8}[/tex] = 320 mol O₂

In order for 80 moles of SO₈ to be produced, 10 moles of S₈ need to react with 320 moles of O₂.

Answers

Answer:

11.9 g of nitrogen monoxide

Explanation:

We'll begin by calculating the number of mole in 6.75 g of NH₃. This can be obtained as follow:

Mass of NH₃ = 6.75 g

Molar mass of NH₃ = 14 + (3×1)

= 14 + 3

= 17 g/mol

Mole of NH₃ =?

Mole = mass /molar mass

Mole of NH₃ = 6.75 / 17

Mole of NH₃ = 0.397 mole

Next, we shall determine the number of mole of NO produced by the reaction of 0.397 mole of NH₃. This can be obtained as follow:

4NH₃ + 5O₂ —> 4NO + 6H₂O

From the balanced equation above,

4 moles of NH₃ reacted to produce 4 moles of NO.

Therefore, 0.397 mole of NH₃ will also react to produce 0.397 mole of NO.

Finally, we shall determine the mass of 0.397 mole of NO. This can be obtained as follow:

Mole of NO = 0.397 mole

Molar mass of NO = 14 + 16 = 30 g/mol

Mass of NO =?

Mass = mole × molar mass

Mass of NO = 0.397 × 30

Mass of NO = 11.9 g

Thus, the mass of NO produced is 11.9 g

22.4 L of hydrogen is taken in a cylinder at zero degree Celsius and at one atm. This gas is transferred to a cylinder of 11.2 L capacity without change in temperature. The present pressure and mass of the gas is ....... & ......

Answers

Answer:

  2 Atm; 2.016 g

Explanation:

Changing the volume without changing the temperature or mass only changes the pressure. Volume and pressure are inversely proportional so halving the volume will double the pressure.

P = 1 Atm, T = 0 °C are "standard" temperature and pressure (STP). The volume of 1 mole of gas is 22.4 L under these conditions. That means the amount of hydrogen gas in the cylinder is 1 mole, so has a mass of 2.016 g.

After the volume reduction, the pressure is 2 Atm, and the mass remains 2.016 g.

Sarah is running a race and is almost to the finish line. In the last 5 seconds, her velocity changes from 2m/s to 4m/s. What is her average acceleration during the last 5 seconds of the race?

Answers

Answer:

[tex]\boxed {\boxed {\sf a= \frac {2}{5} \ or \ 0.4 \ m/s^2}}[/tex]

Explanation:

Acceleration is found by dividing the change in velocity by the time. The formula is:

[tex]a= \frac {v_f-v_i}{t}[/tex]

where [tex]v_f[/tex] is the final velocity, [tex]v_i[/tex] is the initial or starting velocity, and [tex]t[/tex] is the time.

Her velocity changes from 2 meters per second to 4 meters per second in the 5 seconds. Therefore:

[tex]v_f= 4 \ m/s \\v_i= 2 \ m/s \\t=5 \ s[/tex]

Substitute the values into the formula.

[tex]a= \frac { 4 \ m/s- 2 \ m/s}{5 \ s}[/tex]

Solve the numerator and subtract.

[tex]a= \frac { 2 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= \frac{2}{5} \ m/s/s= \frac{2}{5} \ m/s^2[/tex]

This can also be written as a decimal.

[tex]a=0.4 \ m/s^2[/tex]

Her average acceleration during the last 5 seconds of the race is 2/5 or 0.4 meters per square second.

Answer:

Solution :-

Here

Initial velocity = 2 m/s

Final velocity = 4 m/s

Time = 5 sec

v = u + at

4 = 2 + a(5)

4 - 2 = a(5)

2 = 5a

2/5 = a

Hence, acceleration is 2/5 m/s²

Answer:

A nuclear reactor produces electricity in much the same way other power plants do. The chain reaction produces the energy, which turns water into steam. The pressure of the steam turns a generator, which produces electricity.

Explanation:

Nuclear energy originates from the splitting of uranium atoms a process called fission. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Fission takes place inside the reactor of a nuclear power plant. At the center of the reactor is the core, which contains uranium fuel. The uranium fuel is formed into ceramic pellets. Inside each uranium fuel pellet, there are millions of uranium nuclei. When these nuclei are split, a huge amount of energy is released. Some of this energy is from radiation, but the biggest source is kinetic energy. This is the energy that produces heat inside a reactor. The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity. Nuclear plants cool the steam back into water in a separate structure at the power plant called a cooling tower, or they use water from ponds, rivers, or the ocean. The cooled water is then reused to produce steam.

For the night yet balanced equation, No + CuCl2 —> Cu + NiCl3, if you started with 12.00 g of nickel and 42.00 g of CuCl2, how much Copper would you expect to produce Perdue

Answers

Answer:

19.45g of Cu are expect to be produced

Explanation:

Based on the reaction:

2Ni + 3CuCl2 → 3Cu + 2NiCl3

2 moles of Ni react with 3 moles of CuCl2 to produce 3 moles of Cu

To solve this question we must find the moles of each reactant in order to find the limiting reactant. With the limiting reactant we can find the moles of Cu produced and the mass as follows:

Moles Ni -Molar mass: 58.6934g/mol-

12.00g * (1mol / 58.6934g) = 0.204 moles Ni

Moles CuCl2 -Molar mass: 134.45g/mol-

42.00g * (1mol / 134.45g) = 0.312 moles CuCl2

For a complete reaction of 0.204 moles of Ni are required:

0.204 moles Ni * (3 moles CuCl2 / 2 moles Ni) = 0.306 moles of CuCl2

As there are 0.312 moles, CuCl2 is the excess reactant and Ni is limiting reactant.

Moles Cu:

0.204 moles Ni * (3moles Cu / 2 moles Ni) = 0.306 moles of Cu are produced

Mass Cu:

0.306 moles of Cu * (63.546g / mol) =

19.45g of Cu are expect to be produced

Explanation:

Answer:

A. two smaller, more stable nuclei

Explanation:

Nuclear fission is the process in which a heavy nucleus is split into two large fragments of comparable mass to form more stable and smaller nuclei. This results in the release of great amounts of energy. Large nuclei are usually less stable, since it takes more energy to hold its structure together, the larger they are.

of 72.0 grams of liquid water, within the calorimeter, to raise from 25.0°C to 100.°С. Calculate the energy
associated with this reaction.

Answers

We want to solve Q = mcΔT for the liquid water; its change in temperature will tell us the amount of thermal energy that flowed out of the reaction. The specific heat, c, of water is 4.184 J/g °C.

Q = (72.0 g)(4.184 J/g °C)(100 °C - 25 °C) = 22593.6 J

Q ≈ 2.26 × 10⁴ J or 22.6 kJ (three significant figures).

Choose the larger atom from each pair, if possible.
a. Sn or Si,
b. Br or Ga,
c. Sn or Bi,
d. Se or Sn

Answers

Answer:

a. Sn or Si ⇒ Sn

b. Br or Ga ⇒ Ga

c. Sn or Bi ⇒ similar in size

d. Se or Sn ⇒ Sn

Explanation:

The larger atom has a larger atomic radius. We have to consider how varies the atomic radius for chemical elements in the Periodic Table. In a group (column), the atomic radius increases from top to bottom while in a period (file), it increases from right to left.

a. Sn or Si ⇒ Sn

They are in the same group. Sn is on the top, so it has a larger atomic radius.

b. Br or Ga ⇒ Ga

They are in the same period. Ga is located at the left so it has a larger atomic radius.

c. Sn or Bi ⇒ similar

They are not in the same group neither the same period. Bi is located more at the bottom, so it would be larger than Sn, but Bi is also at the right side, so it would be smaller than Bi. Thus, they have comparable sizes.

d. Se or Sn⇒ Sn

They are not in the same group neither the same period. Se is located at the top and right side compared to Sn, so Sn is the larger atom.

Answers

Answer:

[tex]N_{2}O_{5}[/tex]

Explanation:

usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step

least molar ratio:

N = [tex]\frac{1}{1}[/tex] = 1

O = [tex]\frac{2.5}{1}[/tex] = 2.5

when the answer is in decimals we will multiply it by an integer in order to make it a whole number (in this case 2)

O = 2.5(2) = 5

in order to balance, we will also multiply the atoms of N by the same integer

N = 1(2) = 2

thus, the empirical formula is [tex]N_{2}O_{5}[/tex]

Answers

Answer:

The atomic weight Ar, of M is 64

Explanation:

The formula of the given compound is M(OH)₂

Mr, is the molecular weight of a compound and for the given compound, Mr is equal to 98.

Ar, is the atomic weight of the elements in the compound

The molecular weight, Mrof a compound is the mass of one mole mole of that compound. It can be obtained by summing the atomic masses of all elements in that compound. For elements that has more than one atom in the compound, the atomic weight of that element is multiplied by the number of atoms of the element present in the compound and then the sum of the weight of each element gives the molecular weight of the compound.

Onnthe compound above,the atomic weight of the unknown element M, is to be obtained.

Ar of the other elements inn he compound is given : Ar of O = 16, Ar of H = 1.

Molecular weight of the compound, Mr = 98

Calculating for the Ar of M:

(M × 1) + (16 × 2) + (1 × 2) = 98

M +32 + 2 = 98

M + 34 = 98

M = 98 -34

M = 64

Therefore, the atomic weight Ar, of M is 64
