From shortest wavelength to longest wavelength: ultraviolet ,visible light ,infrared
Fed [463]3 years ago

Answer:

Visible light

Ultraviolet

Infrared

Explanation:

Increasing wavelength of different types of electromagnetic waves always start with visible light. It just makes sense, it's the stuff that we can see, it won't/can't harm us. Usually, that spectrum usually ends with Gamma rays. Because those, especially Gamma, are the most harmful to the human body. So, if you ever try to order these types of waves, always start with visible and end with Gamma.

2. A solvent used in cleaning is found to contain only the elements carbon, hydrogen, and chlorine. When a
KIM [24]

mass of C = 0.238 g

mass of H =0.00989 g

mass of Cl = 1.05 g

Explanation:

Determine the masses of carbon, hydrogen, and chlorine in the original sample of the solvent.

First we need to calculate the molar mass of carbon dioxide (CO₂) and water (H₂O)

molar mass of CO₂ = molar mass of C × 1 + molar mass of O × 2

molar mass of CO₂ = 12 × 1 + 16 × 2 = 44 g/mole

molar mass of H₂O = molar mass of H × 2 + molar mass of O × 1

molar mass of H₂O = 1 × 2 + 16 × 1 = 18 g/mole

Now, to find the mass of carbon and hydrogen in the original sample of solvent, we devise the following reasoning:

if              44 g of CO₂ contains 12 g of C

then   0.872 g of CO₂ contains X g of C

X = (0.872 × 12) / 44 = 0.238 g of C

if               18 g of H₂O contains 2 g of H

then   0.089 g of H₂O contains Y g of H

Y = (0.089 × 2) / 18 = 0.00989 g of H

And now, we can find the mass of chlorine:

mass of sample = mass of C + mass of H + mass of Cl

mass of Cl = mass of sample - mass of C - mass of H

mass of Cl = 1.30 - 0.238 - 0.00989

mass of Cl = 1.05 g

What is the pressure exerted by 1.0 mol of a gas with temperature of 20 C and a volume of 7.5 L?
Fofino [41]

We have to assume the gas behaves similar to an ideal gas and we can use the ideal gas law equation

PV = nRT

Where

P - pressure

V - volume - 7.5 L

n - number of moles - 1.0 mol

R - universal gas constant - 0.0821 L.atm/mol.K

T - temperature in kelvin

20 degrees celcius + 273 = 293 K

Substituting the values in the equation

P x 7.5 L = 1.0 mol x 0.0821 L.atm/mol.K x 293 K

P = 3.2 atm

The pressure exerted is 3.2 atm
