can water stay liquid below zero degrees Celsius? how can glass be a liquid if its so hard? what made the hole in the ozone go away?

Answers

Answer 1

Hello. This spreading-out action of the water molecules during freezing also means that applying pressure to water lowers the freezing point. If you apply enough pressure (making it hard for the water molecules to spread out into the solid structure), you can have liquid water several degrees below zero degrees Celsius

The molar mass of hydrogen (H2) is 2. 02 g/mol. A sample contains 4. 00 mol of H2. What is the mass, in grams, of this sample? 1. 98 grams 2. 02 grams 4. 00 grams 8. 08 grams.

Answers

Answer:

8.08 G/mol

Explanation:

This is because a mole just equals 1 amount of something. Example, 1 mol of carbon is about 12 AMU. To convert from Mols to Grams, you need to multiply the substance mass by the amount of mols, this case 2.02g/mol by 4.

Which one of the following indicators would be best to use when titrating 0. 1M morphine (Kb = 1. 6 × 10-6) with 0. 3M HCl?

Answers

When there is 1M morphine (Kb = 1. 6 × 10-6) with 0. 3M HCl, and the pH mathematically given as

pH=4

The indicator is Methyl red

What is best for titrating 0. 1M morphine (Kb = 1. 6 × 10-6) with 0. 3M HCl?

Generally, the equation for the Chemical Reaction is mathematically given as

HCl +BOH--->BCl+H20

Therefore

pH=0.5(pkw-pkb-logl)

pH=0.5()14-5.8-logl

pH=4

In conclusion, The best indicator should have pKa =pH

Hence

Methyl red is best

A sample originally contains 24 grams of a radioactive isotope. After 18 days, 18.8 grams of the isotope remain in the sample. What is the half-life of the isotope

Answers

Around 36 or 37 days, because of the decimal

The sample's decay constant for the given time of radioactive decay is 0.0058 days⁻¹. Thus, the half life of the sample is 119.48 days.

What is radioactive decay?

Heavy unstable radioactive nuclei undergo radioactive decay by the emission of charged particles. They stable isotopes or new atoms by radioactive decay.

It is given that the sample of 24 grams decays to 18.8 grams within 18 days. The decay constant k can be calculated as follows:

k = 1/t log (Ci/Ct)

Where Ci is the initial amount and Ct be the final amount.

k = 1/18 log (24 g /18.8 g)

= 0.0058 days⁻¹

Now, the half life time of the sample can be calculated as:

t1/2 = 0.693 / k

= 0.693/0.0058 days⁻¹

= 119.4 days.

Therefore, the half life of the sample is 119.4 days.

Explanation:

An air condition is used to regulate the temperature of a room by removing heat as well as reducing humidity.

What is temperature?

Temperature is the degree of coldness or hotness of an object or a particular place.

The temperature of an area is affected by the climate and the amount of sunshine.

Also due to heating, water vapor rises into the atmosphere resulting in humidity.

An air condition makes a temperature room cooler by removing heat as well as reducing humidity.

Water can react with hydrochloric acid (a strong acid) to form hydronium and chlorine ions. In this case, water acts as a base. Water also reacts with ammonia (a strong base) to form ammonium and hydroxide ions. In this case, water acts as an acid.

Which option correctly describes the reason for this phenomenon?

1. Water is a neutral compound. It can act as a base when coupled with a strong acid, or as an acid when coupled with a strong base.

2.Every substance can act as a base or an acid depending on the reaction they partake in. This property of substances is called amphotericity.
3. Water acts as a conjugate acid when coupled with a strong acid, or as a conjugate base when coupled with a strong base.

A chemist has 2. 0 mol of methanol (CH3OH). The molar mass of methanol is 32. 0 g/mol. What is the mass, in grams, of the sample? 16 grams 30 grams 32 grams 64 grams.

Answers

The mass, in grams, of the sample of methanol (CH₃OH) is 64 grams.

How we calculate mass from moles?

Mass of any substance can be calculated by using moles as:

n = W/M, where

W = required mass

M = molar mass

In the question that:

Moles of methanol = 2mole

Molar mass of methanol = 32g/mole

On putting these values in the above equation, we get

W = n × M

W = 2mole × 32g/mole = 64g

Hence, 64 grams is the mass of the sample.
