Which will become completely dissociated when dissolved in water? Ammonia pyridine sulfuric acid or acetic acid

Answers

Answer 1

Answer:

Answer:

sulfuric acid

Explanation:

Sulfuric acid is a strong electrolyte.

- Strong electrolytes dissolve completely in water.

Acetic acid and Ammonia is a weak electrolyte.

- Weak electrolytes only partially dissolve in water.

- Hope this helps! If you need further explanation or more help please let me know; I would be glad to help anytime.

Which units express heat capacity

Answers

Answer:

Heat capacity units: J/K

Explanation:

Heat capacity (C) is the amount of heat (Q) required to raise the temperature(T) of a substance by a unit degree.

$C = (Q)/(T)$

It is usually expressed in terms of J/K

Heat capacity is an intensive property i.e. it is not dependent on the amount of the substance. i.e, the amount of heat required to raise the temperature of 1 g of copper per kelvin would be the same as that corresponding to 100 g.

the heat capacity of a defined system is the amount of heat (usually expressed in calories, kilocalories, or joules) needed to raise the system's temperature by one degree (usually expressed in Celsius or Kelvin). It is expressed in units of thermal energy per degree temperature. To aid in the analysis of systems having certain specific dimensions, molar heat capacity and specific heat capacity can be used. To measure the heat capacity of a reaction, a calorimeter must be used. Bomb calorimeters are used for constant volume heat capacities, although a coffee-cup calorimeter is sufficient for a constant pressure heat capacity.

Answers

The difference between heat and temperature is that heat is a type of temperature and temperature is the measure of heat. Hope this helps.

Based on my knowledge, heat is like basically a feeling of warmth/heat. A temperature basically measures the heat like the warmth. Like, heat is climate and temperature measures weather/climate.

Oceans, lakes, ice caps, streams, and clouds are considered to part of what?A. Biosphere
B. Athenosphere
C. Hydrosphere
D. Geosphere

Answers

Hydrosphere is the correct option.Oceans, lakes, icecaps, streams and clouds are considered to be part of hydrosphere. The correctoption in regards to the given question is option “C”.Hydrosphere includes the total mass of water on the surface,underground or over the surface of earth. About 75% of the earth’s surface arecovered by oceans and so a huge part of our planet is covered in water and so hydrosphereis an important aspect. Hope I have answered your question as per your asking.

Answer=C

The hydrosphere is the total amount of water on the planet, encompassing water underground, on the surface of the planet, and in the air. This would include oceans, lakes, ice caps, streams and clouds.

An atom that has 84 protons and 86 neutrons undergoes a reaction. At the end of the reaction, it has 82 protons and 84 neutrons. What happened to the atom?

Answers

During a nuclear reaction, an atom must emit an alpha particle, which consists of 2 protons (positively charged) and 2 neutrons (neutrally charged). Thus, the alpha particle has a charge of +2 (there are no electrons, which are negatively charged, to balance out the two protons). When an atom emits an alpha particle, it will lose this particle, thus losing 2 protons and 2 neutrons as well. Since the atom in the equation goes from 84 protons to 82, and 86 neutrons to 84, it lost 2 protons and 2 neutrons, indicating that it emitted an alpha particle.

C- it emitted an alpha particle in a nuclear reaction (just took the edg test)

These statements describe three different reactions. 1 - An atom shares electrons with another atom.
2 - The nucleus of an atom is split apart.
3 - An atom gains an electron from another atom.

Which reaction(s) most likely release the greatest amount of energy?
1
2
1 and 3
2 and 3

Answers

Answer: Option (b) is the correct answer.

Explanation:

When an atom shares electrons with another atom then it results in the formation of covalent bond.

Whereas when an atom transfer electrons from one atom to another then it results in the formation of ionic bond.

When nucleus of an atom splits then it represents nuclear fission reaction and energy is released during this process.

For example, $^(235)_(92)U \rightarrow ^(144)_(56)Ba + ^(89)_(36)Kr + 3n + 177 MeV$

Therefore, we can conclude that out of the given options, the nucleus of an atom is split apart most likely release the greatest amount of energy.

The answer is number 2. That releases massive amounts of radiation and by the way, that is how atomic bombs are made to detonate.
