If I want to make 100.0 g of my own salt (because I can and that's how I roll), how much elemental chlorine would I need?

Answer:

We need 60.66 grams of chlorine to make 100 grams salt

Explanation:

Step 1: Data given

Mass of salt (NaCl) = 100.00 grams

Molar mass of NaCl = 58.44 g/mol

Molar mass of Cl- = 35.45 g/mol

You also know that for every mole of NaCl you have 1 mole of Na because every molecule of NaCl has 1 atom of Na.

Step 2: Calculate mass of Chlorine needed to make 100 grams of NaCl

Mass Cl = 100(g NaCl) * 1 mol (NaCl)/58.44 g (NaCl) * 1 mol (Cl)/ 1 mol (NaCl) * 35.45 (g of Cl/ 1 mol (Cl)

Mass Cl = 60.66 grams (this means we need 39.34 grams of sodium)

We need 60.66 grams of chlorine to make 100 grams salt

Answer:

60.7g of elemental chlorine

Explanation:

Equation of reaction:

Na + Cl = NaCl

From the equation above,

1 mole (58.5g) of sodium chloride (salt) is formed from 1 mole (35.5g) of elemental chlorine

100g of salt would be produced from (35.5×100g)/58.5 elemental chlorine = 60.7g of elemental chlorine

koban [17]

Answer:

Diagram 1

Explanation:

The solubility of the oxygen gas in water has to do with the interaction of the oxygen with the dipoles in water.

Water is a polar molecule having oxygen as the negative dipole and hydrogen as the positive dipole.

Water can interact with the oxygen atoms in the molecule via intermolecular hydrogen bonds with molecular oxygen as shown in diagram 1.

If the same materials are used to build a voltaic cell and an electrolytic cell, how would the chemical reactions compare?
nadya68 [22]
In the electrolytic cell, depending on the polarity of the battery, either a more vigorous reaction (though the same as the voltaic cell) would occur, or the reverse would.

Convert the pressure 525.4 torr to kPa.
Oduvanchick [21]

Answer:

Option A. 70.0 KPa.

Explanation:

Data obtained from the question include:

Pressure (torr) = 525.4 torr

Pressure (kPa) =?

The pressure expressed in torr can be converted kPa as shown below:

760 torr = 101.325 KPa

Therefore,

525.4 torr = (525.4 x 101.325) / 760 = 70.0 KPa.

Therefore, 525.4 torr is equivalent to 70.0 KPa.

The temperature of a 95.4 g piece of Cu increases from 25.0 °C to 48.0 °C when the Cu absorbs 849 J of heat. What is the specifc
melisa1 [442]
<h3>Answer:</h3>

0.387 J/g°C

<h3>Explanation:</h3>
  • To calculate the amount of heat absorbed or released by a substance we need to know its mass, change in temperature and its specific heat capacity.
  • Then to get quantity of heat absorbed or lost we multiply mass by specific heat capacity and change in temperature.
  • That is, Q = mcΔT

in our question we are given;

Mass of copper, m as 95.4 g

Initial temperature = 25 °C

Final temperature = 48 °C

Thus, change in temperature, ΔT = 23°C

Quantity of heat absorbed, Q as 849 J

We are required to calculate the specific heat capacity of copper

Rearranging the formula we get

c = Q ÷ mΔT

Therefore,

Specific heat capacity, c = 849 J ÷ (95.4 g × 23°C)

                                        = 0.3869 J/g°C

                                        = 0.387 J/g°C

Therefore, the specific heat capacity of copper is 0.387 J/g°C
