# Of the three main states of matter, only gases can be compressed significantly. TRUE FALSE

Answer: False! The three states of matter are solid, liquid, and gas. We can not touch gas, so it can not be compressed.

(A) The dissociation reaction of will be:

The equilibrium expression :

(B) The dissociation reaction of will be:

The equilibrium expression :

(C) The dissociation reaction of will be:

The equilibrium expression :

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

20 POINTS! The CDC (Centers for Disease Control) is a federal agency that monitors the spreading of various diseases and health issues. They have done extensive research on the effects of tobacco on a person's health.

The CDC does a study on smoking with the hypothesis, "If a person smokes more cigarrettes, then they are more likely to develop heart disease". Which of the following should be a controlled variable for this experiment? Choose all that apply.

1. Amount of smoking a person does
2. weight class of the person
3. state where the person lives
4. Whether or not the person develops heart disease

The correct options would be

OPTIONS 1 & 2

The state which a person lives in has nothing to do with the experiment, although it would most likely make it easier to observe. Wheter they develop heart disease or not is the results of the experiment.

A solution of H 2 SO 4 ( aq ) with a molal concentration of 1.94 m has a density of 1.119 g / mL . What is the molar concentration of this solution?

For water should be the same. 1.94 M

Explanation:

Molarity and molality can be the same in some cases. For instance 1 liter of water weighs 1 kg. What is molality? Molality can be defined as the number of moles of substance (known as the solute) that is found in a certain mass of solvent given in kg, that it is dissolved in. The formula for calculating molality is : m = mole solute / kg solvent

However 1.94 m does not make sense with 1.119 density

1.119g/ml= 1119g/1000

1119 g=1000g water + 119g sulfuric acid=

119g/92g/mol=1.29 mol

Therefore= 1.29 molar does not make sense

What does a high boiling point temperature mean about a substance

I dont know if this is the answer you are looking for, but substances with higher boiling points have larger specific heat capacities.

For example water has a specific heat capacity of 4.186 J/g, while gold has a specific heat capacity of 0.129 J/g

The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. ... A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure.

How much pv work is done in kilojoules for the reaction of 0.68 mol of h2 with 0.34 mol of o2 at atmospheric pressure if the volume change is -4.1 l ?

The delta H of -484 kJ is the heat given off when 2 moles of H2 react with 1 mole of O2 to make 2 moles of H2O. You don't have anywhere near that much reactants, only 1/4 as much

actual delta H = 0.34  moles H2 x (-484 kJ / 2 moles H2) = 823 kJ

delta E = delta H - PdeltaV = 823 kJ - 0.41 kJ = 822 kJ
