When added to water, the substance quickly falls to the bottom and then dissolves.
The substance has disappeared after being poured into the water.
The substance makes the water cloudy and then forms a layer on top of the water.
The water remains clear after the substance is stirred into the water with a spoon.
Answer:
Explanation: “Insoluble” generally means that a substance does not dissolve in water. Some examples include: sand, fats, wood, metals, and plastic. When we put them in water and try to mix them, they will not dissolve.

Explain what the color change indicated about the changes in the concentrations of Co(H2O)62+ and CoCl42– in each trial.
Trail one
starting color: purple
added 3 drops of Hcl(aq)
end color:blue
Trail two
start color is :blue
added 3 drops of AgNOv3(aq)
and White stuff forms at the bottom.
end color is: light pink
Addition of HCl leads to te formation of blue CoCl4^2– while the addition of AgNO3 leads to the formation of pink Co(H2O)6^2+.
What is equilibrium?Dynamic equilibrium is said to have been attained in a reaction when the rate of forward reaction is equal to the rate of reverse reaction. Now we have the equilibrium as shown in the image attached.
When we add HCl as in trial 1, the equilibrium position is shifted to the left and blue CoCl4^2– is formed. When we add AgNO3, the Cl^- is precipitated out of solution and the equilibrium shifts towards the left to yield pink Co(H2O)6^2+.

Pots A and B both have plain soil, bean seeds, and the same amount of light. Pot B receives more water (see table). After 50 days the plants are measured. Based on the data, which of the following conclusions can NOT be drawn from the data table?
A plant that receives more water will have more mass
The amount of water a plant receives affects its growth
The taller a plant is, the more mass it has
A plant that receives more water will grow t
A. water per day: 20 m/ height: 24cm/ mass: 3.1g B. Water per day: 60 ml/ height: 24cm/ mass: 9.6g
I think that the answer to this question is the third option. These two plants are of the same height but plant B has more mass. So therefore the statement is not true.
If this is a multiple-choice, then I would also select the fourth option along with the third. Plant B received more water, but it is the same height as plant A.
I hope my answer is satisfactory, and that I was of help to you.

How many joules are required to eat 5.25 g of titanium from 85.5 celsius to 132.5 celsius
The amount of energy required to eat 5.25 g of Titanium from 85.5 celsius to 132.5 celsius is 129 joules.
How do we calculate required heat?Absorbed or released amount of heat will be calculated by using the below formula as:
Q = mcΔT, where
m = mass of titanium = 5.25g
c = specific heat of titanium = 0.523 J/gram degree celsius
ΔT = change in temperature = 132.5 - 85.5 = 47 degree celsius
On putting these values on the above equation we get,
Q = (5.25)(0.523)(47) = 129 joules
Hence required heat is 129 joules.

Calculate the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL.
Considering the definition of dilution, the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL is 0.93 mL.
What is diluionFirst of all, you have to know that when it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeMolarity of the solution in this caseIn this case, you know:
Ci= 4 M Vi= 7 mLCf= ?Vf= 30 mLReplacing in the definition of dilution:
4 M× 7 mL= Cf× 30 mL
Solving:
(4 M× 7 mL)÷ 30 mL= Cf
Cf= 0.93 mL
In summary, the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL is 0.93 mL.

6. Zn + 2HCl → ZnCl2 + H2 How many moles of HCl are produced from the reaction of 2.25 moles of zinc?
Answer:
E. 16.6 mol HCl
Explanation:
The equation for the reaction is;
Zn + 2 HCl --> ZnCl2 + H2
From the reaction 2 moles of HCl produces 1 mole of ZnCl2
Therefore; 8.3 moles of ZnCl2 will be produced by;
= 8.3 moles ×2
= 16.6 Moles of HCl
Therefore; E. 16.6 mol HCl
