Which procedure would best allow a scientist to observe a chemical property of hydrochloric Acid (Hci) solition?
My answer is B
And I chose b
B is correct although I don't like the wording of the sentence.
I would prefer that it say something like "Adding zinc to the HCI solution and noting that a gas is produced."
He is lying don’t trust him
A cooling the HCI solution until it becomes solid and measure in this temperature
B Adding zinc to the HCI solution and examine whether or not bubbles are produced
C placing a conductivity probe into a beaker of HCI solution to determine if it conducts electricity
D Measuring the mass of an volume of a sample of HCI solution to find its density
youre welcome is right
lol im a water bottle doing a......a 80... question practice.... i hate this
You didn't give any choices so your choice must be right?? BTW, hydrochloric acid is HCl.
Okay, The correct answers to this test are as following, I just took the test using the last answers given, and got two questions wrong.
1. B
Reactivity
2. B
Adding zinc to the HCI solution and observing whether or not bubbles are produced.
3. C
He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.
4. D
A chemical change occured, so even if Cash heats it the solid will remain.
5. D
If the substance is a liquid or a solid, the production of odor would indicate a chemical change.
6. A
One
7. A
In Transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.
8. A
Production of odor.
_____
I hope this helps^^ Stay safe, and remember to wash your hands^^
The correct answers are
1. B
2. B
3. A

An amount of nitrogen undergoes a physical change and increases its volume. What can be known about this physical change?
The density changed.
Which tools would Sara use to find an irregularly shaped object's mass and volume?
A balance, water, and a beaker.
What is conserved in physical changes?
mass
What happens to the total mass of a substance undergoing a physical change?
it stays the same
Which property of physical changes explains why matter is conserved in a physical change?
The bonds between atoms do not break; it is only the arrangement that changes.
Marco wants to investigate the chemical properties of sodium bicarbonate, or baking soda. He plans to carry out the tests below.
Test 1: Mix a teaspoon of sodium bicarbonate into a cup of warm water to see if it dissolves.
Test 2: Mix a teaspoon of sodium bicarbonate into a cup of vinegar to see if it fizzes.
Test 3: Heat a teaspoon of sodium bicarbonate in the oven to see if its melting point is less than 400 degrees Fahrenheit.
Which statement provides the best assessment of his tests?
Only Test 2 will indicate a chemical property of sodium bicarbonate. Tests 1 and 3 will show a physical property of the substance.
Four students are analyzing four different substances and recording their findings in this table.
Which most describes this table?
Leonna has a solid, Xiao has a liquid, Blake made a mistake, and Amir has a gas.
Which example illustrates a chemical change?
burning wood
When hydrogen peroxide bubbles, it is undergoing a chemical change. Which statement best describes what is happening?
The atoms in hydrogen peroxide are breaking apart and forming new types of molecules.
Ella makes this table to organize her notes on whether atoms gain or lose energy during the changes of state.
Which changes of state should she place in the column titled "Lose Energy"?
freezing, deposition, and condensation
Which state(s) of matter have no definite shape or volume?
gasses
A substance that will change shape to fit its container but has a definite volume is in a __________ phase of matter.
liquid
The atoms in a sample are close together but can slide past one another. As the atoms lose energy, they move slower. The atoms become locked in place because of attractive forces between them.
Which change of state is taking place?
liquid to solid
