Approximately how many formula units of NaCl are in 116.88g of table salt (NaCl), knowing that the molar mass of NaCl is 58.44g/mol?

Answers

Answer:

116.88g of table salt (NaCl) contains two formula units

Explanation:

Now,

We know that 1 formula unit of sodium chloride has a molar mass of 58.44g/mol

Hence;

Mass of 1 formula unit = 58.44g

Mass of x formula units = 116.88g

x = 116.88g * 1 formula unit/58.44g

x = 2 formula units

Therefore;

116.88g of table salt (NaCl) contains two formula units

Answer:

There are  1.2044 × 10²⁴ formula units of NaCl in 116.88 g of table salt (NaCl)

Explanation:

A formula unit is an empirical formula of the smallest collection or number of atoms in an ionic or covalent combination from which a compounds formula can be established and which are used to represent the compound stoichiometrically

Sodium chloride is an ionic compound and is represented by the formula unit NaCl as it composed of ions and is not therefoe represented by a molecular formula

The given mass of the table salt, NaCl = 116.88 g

The molar mass of NaCl = 58.44 g/mol = The mass of 1 mole of NaCl

1 mole of NaCl contains one Avogadro's number or 6.022 × 10²³ formula units of NaCl,

∴ 58.44 g of NaCl contains 6.022 × 10²³ formula units of NaCl

116.88 g of NaCl will have (116.88/58.44) × 6.022 × 10²³ = 1.2044 × 10²⁴ formula units of NaCl

The number of formula units of NaCl in 116.88 g of table salt (NaCl) =  1.2044 × 10²⁴ formula units of NaCl.

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).

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

please help! What is the empirical formula for a compound that has 1 mole of nitrogen and 2.5 moles of oxygen?

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]

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.

Therefore, pH meter is the only instrument to measure the pH of the solution.

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.

Fe₂(SO₄)₃ + 6KOH —> 3K₂SO₄ + 2Fe(OH)₃

The coefficients are: 1, 6, 3, 2

Explanation:

__Fe₂(SO₄)₃ + __KOH —> __K₂SO₄ + __Fe(OH)₃

To determine the correct coefficients, we shall balance the equation. This can be obtained as follow:

Fe₂(SO₄)₃ + KOH —> K₂SO₄ + Fe(OH)₃

There are 2 atoms of Fe on the left side and 1 atom on the right side. It can be balance by writing 2 before Fe(OH)₃ as shown below:

Fe₂(SO₄)₃ + KOH —> K₂SO₄ + 2Fe(OH)₃

There are 6 atoms of OH on the right side and 1 atom on the left side. It can be balance by writing 6 before KOH as shown below:

Fe₂(SO₄)₃ + 6KOH —> K₂SO₄ + 2Fe(OH)₃

There are 6 atoms of K on the left side and 2 atoms on the right side. It can be balance by writing 3 before K₂SO₄ as shown below:

Fe₂(SO₄)₃ + 6KOH —> 3K₂SO₄ + 2Fe(OH)₃

Now, the equation is balanced.

Therefore, the coefficients are: 1, 6, 3, 2

7. A certain hydrocarbon, CxHy, is burned (reacts with O2 gas) and produces 1.955 g of CO2 for every
1.000 g of H20. What is the empirical formula of this hydrocarbon?
CxHy + (X + y/4) O2 -> xCO2 + y/2 H2O

Answers

Answer:

The empirical formula of the hydrocarbon is C₂H₅

Explanation:

The formula for the hydrocarbon is [tex]C_xH_y[/tex]

The mass of CO₂ produced per 1,000 g of H₂O = 1,955 g

The equation for the chemical reaction is given as follows;

[tex]C_xH_y[/tex] + (x + y/4) O₂ → XCO₂ + y/2H₂O

From the given chemical equation, counting the number of atoms on both sides of the equation, we have;

The molar mass of CO₂ = 44.01 g/mol

The molar mass of H₂O = 18.01528 g/mol

The number of moles of H₂O in 1,000 g of H₂O = 1,000 g/(18.01528 g/mol) = 55.5084351 moles

The number of moles of CO₂ in 1,955 g of H₂O = 1,955 g/(44.01 g/mol) = 44.4217223 moles

Therefore, given that X moles of CO₂ is produced alongside Y/2 moles of H₂O. we have;

X = 44.4217223, Y/2 = 55.5084351

∴ Y = 2 × 55.5084351 = 111.0168702

The ratio of X to Y = X/Y = 44.4217223/111.0168702 = 0.40013488238

∴ The ratio of X to Y = X/Y ≈ 0.4 = 4/10

X/Y ≈ 4/10

The empirical formula is the representation of molecular formula in the smallest whole number ratio of the elements of the molecules

Therefore, when X = 4, Y = 10, from which we have the smallest ratio as;

When X = 2, Y = 5

The empirical formula of the hydrocarbon is therefore, [tex]C_xH_y[/tex] = C₂H₅

The given chemical equation becomes;

C₂H₅ + (2 + 5/4) O₂ → 2CO₂ + 5/2H₂O

C₂H₅ + 3.25 O₂ → 2CO₂ + 2.5 H₂O

We then have;

4C₂H₅ + 13 O₂ → 8CO₂ + 10 H₂O

The empirical formula of the hydrocarbon, [tex]C_xH_y[/tex] = C₂H₅.
