When heat energy is removed, two changes are observed:
Softa [21]

Answer: A is condensation and B is freezing.

The process in which the gas changes to the liquid phase due to the removal of heat is known as condensation. Rains are formed in this way. The water vapour rises. As it raises above it loses heat and then cools down and condenses and comes down as rainfall.

The process in which the liquid changes to a solid on removal of heat is known as freezing. Formation of ice is an example. When the heat is removed at -4 degree Celsius the water freezes to ice.

CONVERT 2 MOL OF OXYGEN TO ATOMS.<br><br>PLeasee...?
kiruha [24]

Answer:

1.2044 × 10^24 oxygen atoms

Explanation:

To convert from moles to atoms, simply multiply the number of moles by Avogadro's number, 6.022 × 10^23

2 × 6.022 × 10^23

=1.2044 × 10^24

the first three ionization energies of an element x are 590, 1145, and 4912 kj mol-1. what is the most likely formula of the com
joja [24]

<u>Answer:</u> The chemical formula is XSO_3

<u>Explanation:</u>

Ionization energy is defined as the amount of energy that is required to remove an electron from a chemical species.

The ionization energy equation for the given values follow:

X(g)\rightarrow X^+(g)+e^-;E_I=590kJ/mol

X^+(g)\rightarrow X^{2+}(g)+e^-;E_I=1145kJ/mol

X^{2+}(g)\rightarrow X^{3+}(g)+e^-;E_I=4912kJ/mol

From the values of ionization energy above, it can be seen that the ionization energy increases as every succeeding electron is removed.

Second ionization energy is a little higher than the first one but there is a huge amount of difference between the third and second ionization energy.

This implies that the ion formed during second ionization energy has a stable configuration and it requires a humongous amount of heat to release the third electron.

Hence, the ion formed will be X^{2+}

Sulfite ion is a polyatomic ion having a chemical formula of SO_3^{2-}

An ionic compound is formed between the two ions and the chemical compound formed between the two will have a formula of XSO_3

Hence, the chemical formula is XSO_3

35mL of acid with an unknown concentration is titrated to completion using 63mL of 3.0 MNaOH.
siniylev [52]

Answer:

5.4 M.

Explanation:

  • At complete neutralization: It is known that the no. of millimoles of acid equal that of the base.

<em>(MV)acid = (MV)NaOH</em>

M of acid = ??? M, V of acid = 35.0 mL.

M of NaOH = 3.0 M, V of NaOH = 63.0 mL.

∴ M of acid = (MV)NaOH / (V)acid = (3.0 M)(63.0 mL)/(35.0 mL) = 5.4 M.
