Answer:

The correct answer are vinegar, sugar water, and soda pop in a sealed bottle.

Explanation:

A mixture that exhibits a similar composition and a uniform appearance throughout is known as a homogenous mixture. Various kinds of homogenous mixtures are generally considered as solutions, as homogenous mixtures are evenly mixed on a molecular or at an atomic level. The homogenous mixtures are difficult to separate. In the given question the examples of homogenous mixtures are vinegar, sugar water, and soda pop.

Which two scenarios illustrate the relationship between pressure and volume as described by Boyle’s law?
Airida [17]

The correct answer is option 2 and 3.

The two scenarios that illustrate the relationship between pressure and volume as described by Boyle’s law are as follows:

2. The volume of an underwater bubble increases as it rises and the pressure decreases.

3. The pressure increases in an inflated plastic bag when the bag is stepped on.

According to Boyle's law, pressure of a gas is inversely proportional to its volume at constant temperature. This means that pressure rises as the volume increases and vice versa.

Arrange the bromine-containing compounds CaBr2, Br2, NBr3, CBr4 in order of increasing predicted boiling point.
Fudgin [204]

Explanation:

In an ionic compound, there will be strong force of attraction between the combining atoms due to the opposite charges present on them.

For example, CaBr_{2} is an ionic compound where calcium has a +2 charge and each bromine atom has a -1 charge.

Therefore, in order to break the bond we need to provide more heat. Hence, boiling point of calcium bromide will be the highest.

NBr_{3} is a covalent compound and as nitrogen is more electronegative in nature and also has a lone pair of electron hence, there will be a net dipole moment.

CBr_{4} is also a covalent compound. And, as bromine is more electronegative than carbon atom so, dipole moment is in the outwards direction. Hence, in CBr_{4} there will be zero dipole moment.

Therefore, its boiling is less than the boiling point of NBr_{3}.

Br_{2} is a covalent compound and there will be no dipole moment.

Thus, we can conclude that given bromine-containing compounds are placed in their increasing boiling point order as follows.

    Br_{2} < CBr_{4} < NBr_{3} < CaBr_{2}
