<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

Liquid state is the second state of matter. In this state, the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. The intermolecular forces between the particles are less as compared to the solid state.

The liquids have a definite volume but does not have a fixed shape as they can take up the shape of container in which they are kept.

The particles have spaces in between them, thus they have high molecular motion.

Hence, the correct answer is Option D.

What's a trend in electron affinity?
Elodia [21]

Electron affinity is the change in energy of an atom with a neutral charge when an electron is added to form an anion. A more negative electron affinity corresponds to a greater attraction for an electron. Electron affinity become less negative down a group and from left to right in the periodic table.

What error in the data is likely to occur if the hydrated salt is heated strongly
Lubov Fominskaja [6]

Answer:

If the hydrated salt is overheated, it causes the anhydrous salt to decompose, causing the product to be lost as gas. The reported percentage of water loss will be too high because the gap between the initial measurement and final (which will be lower due to loss of sample) measurement will widen.

How many molecules of CH4 are in 48.2 g of this compound? A) 2.00 x 1023 B) 5.00 x 10-24 C)1.81 x 1024 D) 4.00 E) 4.64 x 1026 10
Tasya [4]

<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of methane = 48.2 g

Molar mass of methane = 16 g/mol

Putting values in above equation, we get:

\text{Moles of }CH_4=\frac{48.2g}{16g/mol}=3.0125mol

According to mole concept:

1 mole of compound contains 6.022\times 10^{23} number of molecules.

So, 3.0125 moles of methane will contain = 3.0125\times 6.022\times 10^{23}18.141\times 10^{23}=1.81\times 10^{24} number of molecules.

Hence, the correct answer is Option C.

Which compound is correctly balanced by charge in the following reaction?
Mumz [18]

Answer:A,D

Explanation:

Option a:

Sodium has charge +1

Hydroxide has charge -1.

So,sodium hydroxide is balanced.

Option b:

Magnesium has charge +2

Two sulphates has a charge of -2\times 2=-4.

So,magnesium sulphate is not balanced.

Option c:

Magnesium has charge +2

Two hydroxides have a charge of 2\times -1=-2.

So,magnesium hydroxide is balanced.

Option d:

Sodium has charge +1

Sulphate has charge -2.

So,sodium sulphate is not balanced.
