C. the square root of 2gh

Explanation:

The square root of 2gh is equivalent to Torricelli's law in the equation.

given expression:

$\frac{1}{2}$ m v² = mgh

to find v, we make it the subject of the expression:

*multiply both sides of the equation by 2:

2 x( $\frac{1}{2}$ m v² )= 2 (mgh)

mv² = 2mgh

*cancel the mass, m appearing on both sides:

v² = 2gh

* find the square root of both side

v = √2gh

An industrial chemist is studying a sample of an unknown metal. Describe two ways he could change the metal physically and two w

Trava [24]

Answer:

Some of the physical changes used by the industrial chemist in order to identify it is by scratching it with other metals in order to find the hardness of it. Trying to deform it in order to find the malleability, and to heat it and measure the temperature in order to find the melting point.

Some of the chemical changes used by the industrial chemist in order to identify it is by inserting it in water to observe that whether it reacts with it or not, if the reaction is violent, then the metal belongs to either group I or group II. The other method is to insert it in acids of distinct strength and to observe its reaction. The metals belonging to the second group react briskly with acids. The other metals react gradually with acids and others are almost inert.

What is the molarity of 2.00 L of a solution that contains 14.6 g NaCl?

White raven [17]

Answer: The molarity of the solution is 0.125 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n}{V_s}$

where,

n = moles of solute

$V_s$ = volume of solution in L

moles of $NaCl$ = $\frac{\text {given mass}}{\text {Molar mass}}=\frac{14.6g}{58.5g/mol}=0.250mol$

Now put all the given values in the formula of molality, we get

$Molarity=\frac{0.250mol}{2.00L}=0.125M$

Therefore, the molarity of the solution is 0.125 M

A 150.0 mL sample of a 1.50 M solution of CuSO4 is mixed with a 150.0 mL sample of 3.00 M KOH in a coffee cup calorimeter. The t

svp [43]

Mols CuSO4 = M x L = 1.50 x 0.150 = 0.225
mols KOH = 3.00 x 0.150 = 0.450 
specific heat solns = specific heat H2O = 4.18 J/K*C 

CuSO4 + 2KOH = Cu(OH)2 + 2H2O 
q = mass solutions x specific heat solns x (Tfinal-Tinitial) + Ccal*deltat T 
q = 300g x 4.18 x (31.3-25.2) + 24.2*(31.3-25.2) 
dHrxn in J/mol= q/0.225 mol CuSO4 
Then convert to kJ/mol
