Question

X=2 and y=2. For both problems 1. Find the total positive charge of all the protons in x gm of CO2 gas. 2. A metallic sphere has a charge of + x nC. A negatively charged rod has a charge of -y nC. When the rods touches the sphere, x*10^9 electrons are transferred. What are the charges of the sphere and rod now? Please type in response and not upload! Won't see! X=2 and y=2.

Explanation / Answer

1)

1) carbon atom = 6 protons

2 oxygen atoms = 8*2 = 16 protons

1 molecule of CO2 = 16 + 6 = 22 protons

1 mole = 44 grams

1 mole = 6.023 x 10^23 molecules

x grams = (1/44)* x * ( 6.023 x 10^23) * 22 = 3.011 * 10^23 x protons

  charge on 1 proton = 1.6 x 10^-16 C

Total positive charge = 1.6 * 10^-16 * 3.011 * 10^23 x = 4.18 * 10-7 x C = 4.18 x 10^-7 x 2 = 8.36 x 10-7 C

2)

Charge on sphere = x * 10^-9 - x * 10^9 * 1.6 *10^-19 = 2 * 10^-9 - (2*10^9*1.6*10^-19) = 1.68 nC

Charge on rod = - y * 10^-9 + x * 10^9 * 1.6 *10^-19 = - 2 * 10^-9 + (2*10^9*1.6*10^-19) = - 1.68 nC
