Answer:

its axis

Explanation:

the earth rotates on its axis 24 hrs a day in relation to the sun.

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.

The amount of energy required to eat 5.25 g of Titanium from 85.5 celsius to 132.5 celsius is 129 joules.

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.

Explanation:

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+.

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+.

The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

The volume of a given gas can be calculated using the following Charle's law equation:

V1/T1 = V2/T2

Where;

9/325 = V2/450

325V2 = 4050

V2 = 4050/325

V2 = 12.46L

Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

Explanation:

The compounds that can dissociate in water from the options given below are;

Ba(NO3)2

CaSO4

Mg3(PO4)2

Dissociation of compound is the process by which compounds degraded into smaller unit which can also recombine to form larger one in another condition.

When ionic compounds dissociate in water, the water molecules separate the ionic crystal. This is because of the attraction between the positive and negative ions in the crystal.

Therefore, The following compounds dissociate in water.

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.

First 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

In this case, you know:

Replacing 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.

Answer:

2C6H6 + 15O2 = 12CO2 + 6H2O

Explanation:

This is a combustion reaction meaning a substance (in this case Benzene or C6H6) reacts with oxygen gas (O2) and releases energy in the form of light and heat.

so Benzene (C6H6) and Dioxygen (O2) are reactants meaning they are on the left side of the equation

Carbon Dioxide (CO2) and Water (H2O) are the products meaning they are on the right side of the equation

To balance an equation you need an equal amount of each element/compound/polyatomic on each side of the equation

so 2C6H6 + 15O2 = 12CO2 + 6H2O:

(2•6) = 12 C = (12•C) = 12 C ~ 12C = 12C

(2•6) = 12 H = (2•6) = 12 H ~ 12H = 12H

(15•2) = 30 O2 = [(12•2) • (6•1)] = 30 O2

~ 30 O2 = 30 O2

so the equation is now balanced
