Which statement describes a system that consists of sugar crystals dissolving in water?

2 answers:

7 0

To know the answer, you either know what is really the nature and chemistry of a sugar solution. You can also know the answer by knowing the meaning of entropy. Entropy is often interpreted as the degree of disorder or randomness in the system. So the correct statement is that the system becomes more disordered and has an increase in entropy.

What are three ways that carbon atoms can be arranged in hydrocarbon molecules?

Slav-nsk [51]

Answer is: carbon atoms can be arranged straight chain, branched chain and ring.
Hydrocarbon is an organic compound consisting of hydrogen and carbon.
In straight chain carbon atoms are bonded with only two other carbon atoms in elongate chain.
In branched chain at least one carbon is bonded with more than two other carbon atoms.
Ring chain hydrocarbons are cyclic hydrocarbons.

Allotropes are different molecular forms of an element, such as dioxygen (O₂) and ozone (O₃). (b) Calculate the ratio of densiti

kipiarov [429]

The ratio of densities, d₀₃/d₀ is 3:2

We know that at STP all gas have the same volume that is $22.4 \mathrm{~L}$ .

Dioxygen $1 \mathrm{mLe} \mathrm{O}_{2}=32 \mathrm{gm} / \mathrm{moL} .$

Ozone 1 mole $\mathrm{O}_{3}=48 \mathrm{gm} / \mathrm{mol}$ .

$\begin{aligned} \therefore \text { density of } \mathrm{O}_{2} \text { at STP } &=\frac{\text { mass of } \mathrm{O}_{2}}{\text { volume }} \\ \text { or, } d_{\mathrm{O}_{2}} &=\frac{32 \mathrm{gm} / \mathrm{mol}_{\mathrm{o}}}{22.4 \mathrm{~L}} \end{aligned}$

$\therefore$ The ratio of densities,

$\frac{d_{3}}{d o_{2}}=\frac{\frac{48 \mathrm{gm} / \mathrm{mol}}{22.4 \mathrm{~L}}}{\frac{32 \mathrm{gm} / \mathrm{mol}}{22.4 \mathrm{~L}}}$

$\frac{d 0_{3}}{d 0_{2}}=\frac{3}{2}$

do3: do2 = 3:2

Oxygen is found naturally as a molecule. two oxygen atoms strongly bind together with a covalent double bond to shape dioxygen or O2. Oxygen is normally observed as a molecule. it is referred to as dioxygen.

After hydrogen and helium, oxygen is the third most plentiful element in the universe and the most established element in the world. two atoms of the factors combine to generate dioxygen, an odourless and colourless diatomic gasoline with the formulation O2, at ordinary temperature and stress.
