Answer: Option (C) is the correct answer.

Explanation:

A property that does not cause any difference in the chemical composition of the atom is known as a physical property.

For example, boiling point, mass, density, melting point, solubility etc are physical properties.

On the other hand, a property that that cause difference in the chemical composition of a substance is known as a chemical property.

For example, combustion, toxicity, flammability etc are chemical properties.

Therefore, we can conclude that out of the given options solubility is a physical property.

Bowling with a volleyball instead of a bowling ball. Will this make it easier or harder to knock over pins?

Answer:

Definitely harder, since volleyballs are nowhere near as heavy as bowling balls, it’ll be harder too since there wont be much force to knock over pins

Compound A reacts with Compound B to form only one product, Compound C, and it's known the usual percent yield of C in this reac

frez [133]

Given :

Compound A reacts with Compound B to form only one product, Compound C.

The usual percent yield of C in this reaction is 40%.

10.0 g of A are reacted with excess Compound B, and 6.4 g of Compound C

To Find :

The theoretical yield of C.

Solution :

We know, % yield is given by :

$\%\ yield = \dfrac{actual\ yield}{theoretical\ yield }\times 100$

Putting given values , we get :

$40 = \dfrac{6.4}{theoretical\ yield }\times 100\\\\theoretical\ yield=\dfrac{6.4\times 100}{40}\\\\theoretical\ yield=16\ g$

Therefore, theoretical yield of C is 16 g.

Hence, this is the required solution.

At standard temperature and pressure. 0.500 mole of xenon gas occupies

ANEK [815]

Answer:

0.500 mole of Xe (g) occupies 11.2 L at STP.

General Formulas and Concepts:

Gas Laws

STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Stoichiometry

Mole ratio
Dimensional Analysis

Explanation:

Step 1: Define

Identify.

0.500 mole Xe (g)

Step 2: Convert

[DA] Set up: $\displaystyle 0.500 \ \text{mole Xe} \bigg( \frac{22.4 \ \text{L Xe}}{1 \ \text{mole Xe}} \bigg)$
[DA] Evaluate: $\displaystyle 0.500 \ \text{mole Xe} \bigg( \frac{22.4 \ \text{L Xe}}{1 \ \text{mole Xe}} \bigg) = 11.2 \ \text{L Xe}$
