Boiling water on a stove is an example of thermal energy. Thermal energy is produced when the atoms and molecules in a substance vibrate faster due to a rise in temperature.
Compound X meits at 801°C and is a good electrical conductor when dissolved in water.
Compound Y boils at 77°C. is insoluble in water and is a non-conductor of electricity.
Which type of bonding is present in X and in Y?
Answer:
I'm sorry but I cant answer.
Compound X meits at 801°C and is a good electrical conductor when dissolved in water. Compound Y boils at 77°C. is insoluble in water and is a non-conductor of electricity. Compound X is ionic bonding and compound y is covalent bonding.
What is ionic bonding ?The main interaction in ionic compounds is ionic bonding, a type of chemical bonding that involves the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.
The sharing of electrons between two or more atoms forms a covalent connection. When two or more ions join in contact, they can create ionic bonds that are held together by charge differences.
In most cases, ionic compounds are created when a metal reacts with a nonmetal (or a polyatomic ion). The reaction between two nonmetals produces covalent compounds. Binary compounds containing hydrogen are typically covalent compounds since hydrogen is a nonmetal.
Thus, Compound X is ionic bonding and compound y is covalent bonding.

A tank consists of a gaseous mixture of 3.83 g of triselenium diiodide, 2.62 g of ammonium telluride, and 1.82 g of iridium (i) sulfate. What is the partial pressure in atm of ammonium telluride if the total pressure in the tank is 2.795 atm?
Answer: The partial pressure in atm of ammonium telluride is 1.48 atm
Explanation:
According to Raoult's law, the partail pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the total pressure
[tex]p_A=x\times p_{total}[/tex]
where, x = mole fraction
[tex]p_A[/tex] = partial pressure of A
[tex]p_{total}[/tex] = total pressure
[tex]x_{\text {ammonium telluride}}=\frac{\text {moles of ammonium telluride}}{\text {total moles}}[/tex],
[tex]x_{\text {ammonium telluride}}=\frac{\frac{2.62g}{164g/mol}}{\frac{2.62g}{164g/mol}+\frac{3.83g}{333g/mol}+\frac{1.82g}{673g/mol}}=0.53[/tex]
[tex]p_{\text {ammonium telluride}}=0.53\times 2.795atm=1.481atm[/tex]
Thus the partial pressure in atm of ammonium telluride is 1.48 atm

What is the difference between a pure solvent and a solution? Do they have the same physical properties?
Answer:
The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.

Look at this glass of soda. Use your knowledge of thermal energy transfer to explain how heat is affecting the following things: ice, soda, glass, and surrounding air.
Explanation:
Technically, the ice cube melts because the water cools down. This may sound ridiculous at first, but you must consider the fact that the ice melts because it has drawn "heat" (energy) from its surroundings. The "surroundings" being the air and water that surround it (but the water's more important since it's a better conductor of thermal energy).
The surrounding air looses energy while the ice in the glass gains energy.
We know that thermal energy is transferred from a hotter body to a cooler body. If we look as the glass, we will notice that the surrounding air has a greater energy compared to the contents of the glass. The surrounding air looses this energy resulting in the condensation of water vapor in air around the glass.
Similarly, the ice in the glass gains energy and melts. A change of state occurs from solid to liquid as a result of the energy absorbed from the surrounding air.

If a sample contained 3.01 x 1023 atoms of tellurium, how many grams would this be A) 127.6 g B) 255.2 g C) 63.8 g D) 382.8 g
If a sample contained 3.01 x 10²³ atoms of tellurium, that would be 63.8grams.
HOW TO CALCULATE MASS:The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass. However, the number of moles contained in 3.01 x 10²³ atoms of tellurium need to be calculated by dividing the value by Avogadro's number as follows:no. of moles = 3.01 x 10²³ ÷ 6.02 × 10²³
no. of moles = 0.5mole
Mass of tellurium = 127.6g/mol × 0.5
Mass of Tellurium = 63.8grams.
Therefore, if a sample contained 3.01 x 10²³ atoms of tellurium, that would be 63.8grams.

What causes lava to not instantly melt ice sheets when it is poured onto it?
Answer:
Dry ice
Explanation:
Answer:
The lava doesn't melt through ice because the steam ice sits on top of a blanket of steam rather than on top of the ice itself. This means the friction between the lava and the ice is very low.

Explanation:
A.P.E.X
The statement that describes the difference between covalent bonds and Vander Waals forces is that covalent bonds form when two atoms share valence electrons, while Van der Waals forces cause an attraction between nonpolar molecules.
What is covalent and Vander waal bonding?Covalent bonds are bonds formed as a result of sharing of electrons between atoms of a compound. Examples of covalent compounds are C2H2, CO2.
On the other hand, van der waal forces are weak electrostatic forces that attract neutral molecules to one another. Examples of van der waal forces are hydrogen bonding.
Therefore, statement that describes the difference between covalent bonds and Vander Waals forces is that covalent bonds form when two atoms share valence electrons, while Van der Waals forces cause an attraction between non polar molecules.
