Answer:
Hi i got , B. He is right, because there will be more successful collisions between reactants in the 1.0 M solutions.
Explanation: Hope it helps !!
The statement that gives correct explanation is:
B. He is right, because there will be more successful collisions between reactants in the 1.0 M solutions.
Relationship between collisions and concentration:With an expansion in the centralization of any responding substance, the opportunities for crashes between atoms are expanded on the grounds that there are more particles per unit of volume.
As the concentration increases, the collisions between the molecules increases. The solution having 1.0 M concentration will have more collisions due to the increase in the concentration as compared to the solution having 0.5 M.
Thus, option B is correct.

Pure gold has a density of 19.3 g/ml. A gold bracelet has a mass of 412 g and a volume of 22.4ml. Is the bracelet pure gold? Explain.
Answer:
[tex]\boxed {\boxed {\sf No, \ the\ densities \ aren't \ equal}}[/tex]
Explanation:
First, let's find the density of the gold bracelet.
Density can be found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the bracelet is 412 grams and the volume is 22.4 milliliters.
[tex]m=412 \ g\\v= 22.4 \ mL[/tex]
Substitute the values into the formula.
[tex]d=\frac{412 \ g}{22.4 \ mL}[/tex]
Divide.
[tex]d=18.3928571 \ g/mL[/tex]
Let's round to the nearest hundredth.
The 2 in the thousandth place tells us to leave the 9 in the hundredth place.[tex]d \approx 18.39 \ g/mL[/tex]
The density of the bracelet is about 18.39 grams per milliliter.
Now, let's compare the bracelet's density to pure gold's density.
[tex]bracelet= 18.39 \ g/mL\\pure \ gold=19.3 \ g/mL[/tex]
It's quite clear that the two values are not equal. Therefore, the bracelet cannot be made of pure gold, because it's density doesn't match pure gold's.

The temparature of boiling water cannot be measured by _______ temparature
Answer:
Temperature of boiling water cannot be measured by a Clinical thermometer The reason behind this is that the range of clinical thermometer varies between only 35° C to 42° C.
Answer:
It cannot be measured using clinical thermometer.
Explanation:
Thermometer is an instrument use for measuring temperature that is the degree of hotness and coldness
The temperature of boiling water cannot be measured by clinical temperature or thermometer because it can only measure temperature ranges from 30 to 40°c and the temperature for boiling water is 100°c.
How many moles contain 9.15 x 1022 atoms of Ag?
Select the correct response.
0.152 mol
9.15 mol
0.325 mol
5.51 mol
Answer:
0.152 molExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{9.15 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.151993...[/tex]
We have the final answer as
0.152 molesHope this helps you

What are the properties of solids? Of liquids? Of gases?
Answer: Hope this helps.
Gas: assumes the shape and volume of its container particles can move past one another, compressible, lots of free space between particles.
Liquid: assumes the shape of the part of the container which it occupies particles can move/slide past one another, not easily compressible, little free space between particle.
Solid: retains a fixed volume and shape, rigid - particles locked into place, not easily compressible, little free space between particles.
When vinegar is added to baking soda, Carbon dioxide is formed. Name the reactant(s) and product(s)
(Earn 15 points)
Answer: The "equation" here is vinegar + baking soda = carbon dioxide. The reactants are vinegar and baking soda. The products are carbon dioxide.
Explanation: The reactants are the "ingredients," or the two or more substances you mix in order to form the product, the ending result. In this situation, you mixed vinegar and baking soda, so those are the reactants. You ended up making CO2, the product.

Like Gravity, electrostatic forces always attract
An atom with an equal number of protons and electrons can pull with an electrostatic force
An ion with a negative charge will repel another ion with a negative charge
Electrostatic forces are a fundamental force in the universe
Answer:
Option 3 or C An ion is all in Electrostatic forces so it's c if its not I'll work it out for you
An ion with a negative charge will repel another ion with a negative charge is the correct statement.
What is electrostatic forces?The electrostatic force is the force that exists between electrically charged particles or objects at rest means that objects having similar charge repel each other whereas objects having different charges attract each other.
An ion with a negative charge will repel another ion with a negative charge is the statement true about electrostatic forces because electrostatic force always occur between static object having charges on it.

Consider the compound Al(OH)3. What type of
solid does it form?
crystal lattice
glass
metal
molecule
Answer:
crystal lattice
Explanation:
The Aluminium Hydroxide forms a crystal lattice solid structure, the correct option is A.
What is a Crystal Lattice?The symmetrical, three-dimensional structural configuration of points representing atoms, ions, or molecules that make up a crystalline material is known as the crystal lattice.
It can be described as the geometrical arrangement of the crystalline solid's atoms, ions, or molecules as points in space.
Al(OH)3 is called Aluminium hydroxide, It is found in nature as the mineral gibbsite.
It is an amorphous white powder and is insoluble in water but soluble in acidic and alkaline solutions.
It can be used to relieve indigestion and stomach discomfort.
Al(OH)₃ is composed of two layers of hydroxyl groups, with aluminum ions filling two-thirds of the octahedral holes in the center of the structure.
There are four identified polymorphs. Each has layers of octahedral aluminum hydroxide units connected by hydrogen bonds.
So, the solid form of the compound Al(OH)₃ has a crystal lattice structure.
