The density of chlorine will be  3.163 g/L.

The mass of a substance per unit of volume is its density. According to Graham's law, a gas's rate of effusion is inversely proportional to its square root density. When a material's particles are concentrated in a low area, they tend to travel to the place where the concentration is highest. When we use perfume or a scented spray in one area of the room and subsequently can smell it throughout the entire space, that is a simple illustration of this process.

rate1 = H2 = 5.93

rate2 = Cl2 = 1

The molecular weight of H2 = 2.016

The molecular weight of Cl2 = x.

By Graham's Law:

5.93 / 1 = x / 2.016

35.1649 = x / 2.016

x = 70.89 g/mol

Immediately rinse chemicals off with a lot of water.                                  

Different assistance must be used because different chemical accidents might occur in various ways.

To provide the person access to fresh air, remove them from the factory or work location. Make sure your company has a plan in place for what to do if a worker becomes unconscious or is unable to move. If the person has inhaled chemicals, administer oxygen from an oxygen tank.

Immediately rinse chemicals off with lots of water for at least 15 minutes. The more quickly and for a longer period of time you start to pour water over the region, the more damage you will limit. Chemicals that catch fire or absorb quickly through the skin must be washed for a longer time, 30 minutes to 1 hour.

Right away, rinse the eye or both eyes. Rinse for at least 15 minutes while using a lot of water. If you have an emergency eye wash, activate it while keeping your eyes open with your fingers. If you must use your hands to splash water in your eyes, keep them open while doing so. Seek assistance in keeping them open.

Look for the chemical label or any other relevant information. Typically, the label will provide information on "ingestion" in the first aid section.

3 grams of Cu = 6.022 x 10^23 atoms of copper.

Answer:

2.84 × 10^22 atoms

Explanation:

To calculate the number of atoms in 3 grams of Cu, we can use avogadro's constant where:

[tex]1 \: mole = 6.02 \times 10 {}^{23} \: atoms[/tex]

Firstly, we have to calculate the number of moles in 3 grams of Cu. The formula to calculate moles is:

[tex]moles = \frac{mass}{molar \: mass} [/tex]

the mass = 3g and the molar mass = 63.55 (this value can be found in the periodic table)

Substitute the values in formula:

[tex]moles = \frac{3}{63.55} [/tex]

[tex]moles = 0.0472[/tex]

Now use the number of moles to convert to atoms using avogadro's number, where x is the unknown number of atoms we want to find:

[tex]1 \: mole : 6.02 \times 10 {}^{23} \: atoms[/tex]

[tex]0.0472 \: moles : x \: atoms[/tex]

Cross multiply and equate to solve for x:

[tex]1 \times x = 6.02 \times 10 {}^{23} \times 0.0472[/tex]

[tex]x = 6.02 \times 10 {}^{23} \times 0.0472[/tex]

[tex]x = 2.84 \times 10 {}^{22} \: rounded \: to \: 3sf[/tex]

The heat in joules is released when 25. 0 g of water (C = 4. 184 J/g°C) is cooled from 80. 0°C to 30. 0°C is -5210 J

To find the amount of heat released when a substance is cooled, we can use the equation:

q = mcΔT

where q is the amount of heat (in joules), m is the mass of the substance (in grams), c is the specific heat capacity of the substance (in joules per gram per degree Celsius), and ΔT is the change in temperature (in degrees Celsius).

Given the information in the question, we have:

m = 25.0 g

c = 4.184 J/g°C

ΔT = 30.0°C - 80.0°C = -50.0°C

So, we can substitute these values into the equation and get:

q = (25.0 g)(4.184 J/g°C)(-50.0°C)

q = -5210 J

Therefore, the amount of heat released when 25.0 g of water is cooled from 80.0°C to 30.0°C is -5210 J.

A negative sign means the heat is absorbed during the cooling process, it is an endothermic process.
