39. Chromium and chlorine form an ionic compound whose formula is CrCl3. The name of thiscompound is
a. chromium (III) chloride
c. monochromium trichloride
b. chromium chlorine
d. chromium(III)trichloride

Answers

Answer:

a. chromium (III) chloride

Explanation:

Chromium chloride is also binary ionic compound composed of only two element chromium and chlorine.

When naming these compounds the name of metal or cation is written first and anion is written after the cation. The anions are non meals.

The anion name is end with suffix " ide".

such as chromium chloride.

The (III) shows the oxidation number of metal. In given compound the oxidation state of chromium is +3 while chlorine chow the oxidation state of -1 that's why three chlorine atoms are attached with one chromium atom.

is it possible for a cup of tea and tea pot that is full of tea to have the same thermal energy? explain

Answers

Answer:

Yes, this is possible.

Explanation:

It is possible that a cup of tea and teapot filled with tea has the same thermal energy. This often occurs in the real world, when two different thermal energy bodies are placed next to each other.

When two bodies are placed next to each other and these two bodies have different temperatures, there is a transfer of thermal energy between them, which allows them to present the same thermal energy.

With that we can conclude that the teapot received thermal energy from the stove and passed that energy to the tea that was inside it, in this way, tea and teapot had equal thermal energy. This tea, with high thermal energy, was placed in a cup with low thermal energy. The tea promoted a transfer of heat between him and the cup, allowing them to equalize their temperatures and consequently the thermal energy.

In this way, the cup has the same temperature as the tea, which has the same temperature as the teapot.
it is quite possible as you can see when a teapot is hot a cup of tea can be hot using a thermometer u can cheak the temperature

Tamara pours hot tea into a cold mug. A few moments later, she picks up the mug, and it is now warm.What is the main form of energy transfer involved in heating the mug?

Answers

Answer: Conduction

Explanation: MODES OF HEAT TRANSFER

Conduction: This type of heat transfer happens when there is direct contact between the two object.

Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).

Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

Thus as there is direct contact between the mug and the tea, the heat transfer occurs through conduction.
Conduction. Conduction is the transfer of heat through touch. The hot tea gave some heat to the cold mug by touching the mug, therefore it is conduction.
