Consider the terms elements, compounds, and mixtures. What do you think each of
these is?
Answer:
Explanation:
Element -
It is the basic unit of matter, which cannot be broken down into substances by any way but can be combined to form new substances.
It is a pure substance.
It classifies into metals, non-metals, metalloids and noble gases.
Example - Hydrogen, Carbon, Oxygen
Compounds -
It is a combination of two or more elements.
It is a pure substance.
Through chemical reactions, they can be broken down into metals.
Example - Water, Carbon dioxide
Mixtures -
It is a combination of two or more elements or compounds or both.
The substances combined in a mixture are in a particular ratio.
Example - Chalk powder, Washing Soda

Name the property of salt investigated in the above experiment
which experiment please involve a clip
in the photoelectric effect, what happens when light hits the metal
Answer:
electrons are knocked off atoms, causing electricity to flow.
Explanation:
write the importance of exothermic reactions
Answer: An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.
Exothermic reactions are important to forensic sciences and particularly to fire and explosion investigation. When a chemical reaction requires heat (rather than producing it) and results in cooling down the surroundings, it is conversely called endothermic.
Example-
Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake.

How many moles of Ba(OH)2 are present in 205 mL of 0.600 M Ba(OH)2?
Answer:
Explanation:
0.180 moles of Ba(OH)2 are present.
Answer:
[tex]\boxed {\boxed {\sf 0.123 \ mol \ Ba(OH)_2}}[/tex]
Explanation:
Molarity is a measure of concentration in moles per liter. It is calculated using the following formula:
[tex]molarity= \frac{moles \ of \ solute}{liters \ of \ solution}[/tex]
The molarity of the solution is 0.600 M Ba(OH)₂. 1 molar (M) is also equal to 1 mole per liter, so the molarity is 0.600 moles of Ba(OH)₂ per liter.
The volume of the solution is 205 milliliters, however, we need to convert the volume to liters. Remember that 1 liter contains 1000 milliliters.
[tex]\frac { 1 \ L}{1000 \ mL}[/tex][tex]205 \ mL * \frac { 1 \ L}{1000 \ mL} = \frac {205}{1000} \ L = 0.205 \ L[/tex]Now we know the molarity and volume, but the moles are still unknown.
molarity = 0.600 mol Ba(OH)₂/ L moles of solute = x liters of solution = 0.205 LSubstitute these values into the formula.
[tex]0.600 \ mol \ Ba(OH)_2 /L = \frac{x}{0.205 \ L}[/tex]
We are solving for x or the moles of solute, so we must isolate the variable. It is being divided by 0.205 liters. The inverse of division is multiplication. Multiply both sides by 0.205 L.
[tex]0.205 \ L *0.600 \ mol \ Ba(OH)_2 /L = \frac{x}{0.205 \ L} * 0.205 \ L[/tex]
[tex]0.205 \ L *0.600 \ mol \ Ba(OH)_2 /L =x[/tex]
The units of liters cancel.
[tex]0.205 *0.600 \ mol \ Ba(OH)_2 =x[/tex]
[tex]0.123 \ mol \ Ba (OH)_2 = x[/tex]
The original measurements had at least 3 significant figures. Our answer currently has 3 sig figs, so we don't need to round.
There are 0.123 moles of barium hydroxide.

Hydrogen bromide is found in volcanic gas. What is the chemical formula for
this compound?
Answer:
Hydrogen bromide, anhydrous appears as a colorless gas with a pungent irritating odor. Corrosive. Heavier than air. Prolonged exposure to fire or intense heat may result in the violent rupture and rocketing of the container. Long-term exposure to low concentrations or short-term exposure to high concentrations can result in adverse health effects from inhalation. Used to make other chemicals and as a catalyst in the manufacture of chemicals. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 2 ppm Source/use/other hazard: Chemical manufacturing industry; very corrosive.
