What is the equation for measuring the change in thermal energy?

Daniel [21]

Answer:

Explanation: I think...

Thermal Energy formula Q = mcΔT

Q = Thermal Energy(J)

m = Mass(kg)

c = Specific Heat(J/kg°C)

ΔT = Change in Temperature(°C)

you have to write the equation based on what you are working on

250 mL 0.1 M HCl solution is mixed with 250 mL

pishuonlain [190]

Answer:

The concentration of OH⁻ in the mixture is 0.05 M

Explanation:

The reaction of neutralization between HCl and NaOH is the following:

H⁺(aq) + OH⁻(aq) ⇄ H₂O(l)

The number of moles of HCl is:

$n_{HCl} = C*V = 0.1 mol/L*0.250L = 0.025 moles$

Similarly, the number of moles of NaOH is:

$n_{NaOH} = C*V = 0.2 mol/L*0.250L = 0.05 moles$

Now, from the reaction of HCl and NaOH we have the following number of moles of NaOH remaining:

$n_{NaOH} = 0.05 moles - 0.025 moles = 0.025 moles$

Finally, the concentration of OH⁻ in the mixture is:

$C =\frac{n_{NaOH}}{V_{T}}=\frac{0.025 moles}{0.250*2 L} = 0.05 moles/L$

Therefore, the concentration of OH⁻ in the mixture is 0.05 M.

I hope it helps you!

An 800-newton person is standing in an elevator. If the upward force of the elevator on the person is 600 Newtons, the person

IceJOKER [234]

Answer:

person is accelerating downwards

Explanation:

We are told that the force of the person standing on the elevator is 800 N acting downwards.

We are also told that the upward force of the elevator on the person is 600 Newtons.

This means that Upward force is lesser than downward force and thus the person is accelerating downwards

Calculate the maximum absolute uncertainty for R if:

Radda [10]

Answer:

ΔR = 9 s

Explanation:

To calculate the propagation of the uncertainty or absolute error, the variation with each parameter must be calculated and the but of the cases must be found, which is done by taking the absolute value

The given expression is R = 2A / B

the uncertainty is ΔR = | $\frac{dR}{dA}$ | ΔA + | $\frac{ dR}{dB}$ | ΔB
