PbI₄ + CrCl₃ --> PbCl₄ + CrI₃

There is 1 Pb and Cr atom on both sides.
There are 3 Cl atoms on the left side and 4 on the right side.
There are 4 I atoms on the left side and 3 on the right side.

PbI₄ + 4CrCl₃ --> 3PbCl₄ + CrI₃
Cl atoms are now balanced

3PbI₄ + 4CrCl₃ --> 3PbCl₄ + 4CrI₃
All of the atoms are now balanced.

3PbI₄ + 4CrCl₃ --> 3PbCl₄ + 4CrI₃

Individual finance charge is usually calculated using the the person APR [Annual Percentage Rate], amount of debt owe and the time period been considered.

Two moles of ideal He gas are contained at a pressure of 1 atm and a temperature of 300 K. 34166 J of heat are transferred to th
iragen [17]

Explanation:

The given data is as follows.

       n = 2 mol,         P = 1 atm,         T = 300 K

        Q = +34166 J,         W= -1216 J (work done against surrounding)

       C_{v} = \frac{3R}{2}

Relation between internal energy, work and heat is as follows.

      Change in internal energy (\Delta U) = Q + W

                                   = [34166 + (-1216)] J

                                   = 32950 J

Also,  \Delta U = n \times C_{v} \times \Delta T

                      = 3R \times (T_{2} - T_{1})

                 32950 J = 3 \times 8.314 J/mol K \times (T_{2} - 300 K)

                \frac{32950}{24.942} = T_{2} - 300 K

                            1321.06 K + 300 K = T_{2}    

                                       T_{2} = 1621.06 K

Thus, we can conclude that the final temperature of the gas is 1621.06 K.

In which situation is no work considered to be done by a force?
Masja [62]

If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.

If the angle is 45, then there is still some work involved.

The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.

How many mL of a 0.375 M solution can be made from 35 g of calcium phosphate?
andrew11 [14]

Answer:

300 mL

Explanation:

the unit formula of calcium phosphate is Ca3(PO4)2

molar mass of Ca3(PO4)2 = (3×40 + 2×31 + 8×16) g/mol = 310 g/mol

n = m/M = 35 g/(310 g/mol)

c = n/V

V = n/c = [35 g/(310 g/mol)]/0.375 mol/L

V = 0.30 L = 300 mL
