Answer:

D. Both A and C

Explanation:

When balancing a redox equation, you'll first of all check for the oxidation equation, balance the number of moles and then the charges and move next to reduction equation and do the same. Then add up both half-equations to give the overall redox equation. The subscripts on each molecule isn't really required separately since they'll be balanced during the half equations.

Use the mole concept to calculate the number of atoms that are in a 1.75-mol sample of CHCl3.
Fiesta28 [93]
This is how I got to that answer. Since we don't know how many atoms there are in a mole, we use the number 6.02 x 10^-23. Now, just plug in what you have in the equation: 

<span>1.75 moles ChCl3 x (6.02 x 10 ^-23) / 1 mole = 1.0535 x 10^-22 atoms. </span>

Can someone help? I wasn't at school the day we did this and I don't understand.
Anton [14]
1) 2700 kg/l
2) 13.6 kg/l
3) 0.1578 kg
4) 8921.5 kg/m3
5) 1.59 kg/l
6) 1.84 kg/l
7) 0.21965 kg
8) 11331.9 kg/m3
9) 7.9167 kg/l
10) 238.095 cm3

Just divide the masses by volume to find out the density, multiply the volume with density to find out the mass and divide the mass by density to find out the volume.
To turn the result into SI unit (kg/l), divide the g by 1000 and ml by 1000.
