Some of the properties are:

1. Gamma, γ-rays are not deflected by electric and magnetic fields. It shows that they do not have any charge.

2. Gamma, γ-rays are electromagnetic waves like X-rays. The wavelength of γ-ray photon is smaller than that of X-rays.

3. The rest mass of a Gamma, γ-ray photon is zero. (Photon has mass zero but it has momentum, why?)

4. Gamma, γ-rays travel with the speed of light.

5. Gamma, γ-rays have very large penetrating power. They can pass through several centimeter of iron and lead.

6. Gamma, γ-rays can produce fluorescene in a substance like willimite.

Describe how you would prepare 350 ml of 0.100 m c12h22o11 starting with 3.00l of 1.50 m c12h22o11

Leona [35]

To prepare 350 mL of 0.100 M solution from a 1.50 M solution, we simply have to use the formula:

M1 V1 = M2 V2

So from the formula, we will know how much volume of the 1.50 M we actually need.

1.50 M * V1 = 0.100 M * 350 mL

V1 = 23.33 mL

So we need 23.33 mL of the 1.50 M solution. We dilute it with water to a volume of 350 mL. So water needed is:

350 mL – 23.33 mL = 326.67 mL water

Steps:

1. Take 23.33 mL of 1.50 M solution

<span>2. Add 326.67 mL of water to make 350 mL of 0.100 M solution</span>

Compare the electronegativity of H and O in the polar covalent bonds of a water

ExtremeBDS [4]

Answer:

The O atom will tend to attract the electrons.

Explanation:

The electronegativity of O (3.5) is much higher than H (2.1), which means it is more likely to attract electrons. The higher the electronegativity, the more attractive.

Intermolecular forces do not have any effect on determining the physical properties of

djyliett [7]

Answer:

False

Explanation:

The physical properties of melting point, boiling point, vapor pressure, evaporation, viscosity, surface tension, and solubility are related to the strength of attractive forces between molecules. These attractive forces are called Intermolecular Forces.

What is the volume of 4.78g of O2 gas at STP?

My name is Ann [436]

Answer:

Explanation:

The trick here is to realize that if you know the volume of a gas at STP, you can use the fact that

mole of any ideal gas occupies

22.7 L

under STP conditions to calculate how many moles of gas you have in your sample.

Under STP conditions:

1 mole of an ideal gas = 22.7 L

−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−

In your case, you know that your sample of gas occupies

2.28 L

under STP conditions, which are currently defined as a pressure of

100 kPa

and a temperature of

∘

This means that your sample will contain

2.28

⋅

molar volume of a gas at STP

0.10044 moles gas

Now, the molar mass of the gas is the mass of exactly

mole of the gas. In your case, you know that you get

3.78 g

for every

0.10044

moles, which means that you have

mole

⋅

3.78 g

0.10044

37.6 g

Since this is the mass of

mole of gas, you can say that the molar mass of the gas is

molar mass = 37.6 g mol
