Question 3 options:
Truck A has greater kinetic energy.
Truck A will have a greater stopping distance.
Truck B will have a greater stopping distance.
Truck B has less kinetic energy.
Answer:
C, Truck B will have a greater stopping distance. Took the test got it right.
Explanation:
Answer:
the answer is c
Explanation: the truck with less kg means that it will be more likely to stop fast but if you have a high kg it will slide till it stops thus the answer is c

How many atoms of each element are in the compound AgNO3? (Hint: Ag is the
symbol for silver, N is the symbol for nitrogen, and O is the symbol for oxygen.)
1 silver, 1 nitrogen and 3 oxygen
Subscripts show the number of atoms of each element in a compound
There is no subscript after Ag which shows there is only one silver atom. There is no subscript after N which shows there is only one nitrogen atom. However, there is a 3 in the subscript after O which shows there are 3 oxygen atoms

How many grams of sodium hydroxide are present in 250.0 mL of a 0.300 M NaOH solution?
Why must you continue to increase the temperature as you perform distillation ?
Answer:
It is possible to separate several distinct compounds according to their varying volatilities by altering the temperature of the distillation process. A nonvolatile solute, on the other hand, will always remain in the solution if you have a nonvolatile solute in your solution.
Explanation:
Hope it helps:)
Answer:
The reason for this is that the composition of the vapor that is distilling varies continuously during the distillation

which choice is an element? Air, oxygen, water, or sodium cholride
Answer:
Oxygen is an element.
Explanation:
Out of the choices listed, oxygen is the only element. The other choices are incorrect because air is a mixture of nitrogen, oxygen, carbon dioxide, water vapors, and some other gases; water is a compound of hydrogen and oxygen; and sodium chloride is a compound of sodium and chloride ions; meanwhile, oxygen is a pure element.
Why is it important that you not breathe on the baking soda test?
Baking soda is a salt of sodium and bicarbonate ions. In a soda test, the breath will raise the temperature as it contains water vapor and decomposes the soda.
What is the baking soda test?The baking soda is also called sodium bicarbonate, and the test uses sodium bicarbonate as a reactant. It is also a leavening agent that is used in the preparation of food.
Breath contains some amount of water vapor that alters the test by diluting it and resulting in the clouding of the test. The water vapor decomposes the baking soda and alters the test results.
Therefore, breath contains water vapor.

In your own words, what is the conservation of mass?
Answer:
In chemistry, the law of conservation of mass states that the mass of the products (the chemical substances created by a chemical reaction) will always equal the mass of the reactants (the substances that make the chemical reaction). Think of it as being similar to balancing an algebraic equation.
Explanation:
(winks and runs off)
Answer:
Mass cannot be created or destroyed.
Explanation:
Conservation of mass is "a principle stating that mass cannot be created or destroyed" (Oxford Languages).

NaC2H3O2 HOH --> HC2H3O2 NaOH Since the two products are a weak acid and a strong base, we expect this mixture to be basic. When NaF reacts with water in the same manner, the products would be NaOH and _______.
The products of the reaction would be NaOH and HF
From the question,
We are to determine the products of the reaction between NaF and water in the same manner as the given reaction.
To determine the other product, we will write the equation for the reaction
The equation for the reaction is
NaF + H₂O → NaOH + HF
Hence, the products of the reaction would be NaOH and HF.

why are metals generally good conductors of electric current?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.
The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.
The density of gold is 19. 3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = ). 25 cm3. 67 cm3 1. 48 cm3 2. 50 cm3.
Answer:
0.67 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\[/tex]
From the question
mass = 13 g
density = 19.3 g/cm³
We have
