<span>A fast way to separate the mixture would be to use a magnet. Iron is magnetic while copper is not. The second method would be to visually separate them since iron and copper distinctly different colors.</span>

How many protons z and how many neutrons n are there in a nucleus of the most common isotope of silicon, 2814si?
zheka24 [161]
The 28 is the sum of the protons and neutrons in the element silicon.
ALL silicon atoms have 14 protons in the nucleus, so we can turn this into an equation:
#protons + #neutrons = 28
14 + #neutrons = 28
#neutrons = 14
#protons = 14

If 85.0 L of helium at 29.0°C is compressed to 32.0 L at constant pressure, what is the new temperature?
Feliz [49]

Answer:

113.69°k

Explanation:

V1=85L of helium                         V2=32L

T1= 29°C +273= 302°K                 T2=?

     T2=<u>TIV2</u>

              V1

    T2=<u>(302)(32)</u>= <u>9664</u>

                85           85

    T2=  113.69°K

6. A piece of solid gold was heated from 274K to 314K. 35.73 of energy was needed to raise the temperature.
ivanzaharov [21]

From Q = mcΔT, we can rearrange the equation to solve for mass, m = Q/cΔT. The specific heat capacity, c, of solid gold is 0.129 J/g °C. I'm assuming that the energy is given in joules, as it's not specified in the question as written.

m = Q/cΔT = (35.73 J)/(0.129 J/g °C)(40.85 °C - 0.85°C)

m = 6.92 g of gold was present
