Answer:

The answer to your question is:  PCl₃

Explanation:

Data

P = 10.15 mg

Cl = 34.85 mg

Convert mg to moles

                                  31 mg of P ----------------- 1 mmol

                                  10.15 mg  ------------------   x

                                  x = 0.327 mmol of P

                                   35.5 mg of Cl ------------  1 mmol

                                    34.85 mg -----------------  x

                                  x = 0.982 mmol of Cl

Divide by the lowest number of mmoles

For P = 0.327 / 0.327 = 1

For Cl = 0.982 / 0.327 = 3

Empirical formula

                               PCl₃

Use bond enthalpy values to calculate the enthalpy change for the following reaction. Then, label if the reaction is endothermic
Mila [183]

Based on the bond energies given, the enthalpy change for the reaction of is -33 kJ and the reaction is exothermic.

<h3>What is the change in bond energy of a reaction?</h3>

The change in bond energy of a reaction is calculated using the formula below:

  • change in bond energy = sum of energies of bonds broken - sum of energies of bonds formed

A reaction is exothermic if the change in bond energy is negative.

A reaction is endothermic if the change in bond energy is positive.

Given the bond enery values above:

sum of energies of bonds broken = 4 × C-H + Br-Br

sum of energies of bonds broken = 4 × 413 + 193 = 1845 kJ

sum of energies of bonds formed = 3 × C-H + C-Br + H-Br

sum of energies of bonds formed = 3 × 413 + 276 + 363 = 1878 kJ

Thus;

change in bond energy = 1845 - 1878 = -33 kJ

  • The reaction is exothermic because the change in bond energy is negative.

Therefore, the enthalpy change for the reaction of is -33 kJ and the reaction is exothermic.

Find the time Δt it takes the magnetic field to drop to zero. Express your answer in terms of some or all of the quantities a, B
Mekhanik [1.2K]
Δt= \frac{NB_0 \pi a^2 }{IR}

This because ε = dΦ/dt, and emf is a voltage so it can also be written as dΦ/dt = IR

Because ΔΦ= ABcosθ for each of the N loops and cosθ is just 1 here only A needs to be replaced, and it can be replaced with A=πr^2, which makes that part of the equation ΔΦ_m=N*B0*πa^2

Why is one side of the moon called "the dark side of the moon"?
dlinn [17]
The 'dark side' of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. ... It is only 'dark' to us, as that hemisphere can never be viewed from Earth due to a phenomenon known as 'Tidal Locking'
