Answer:
Neutrons
Explanation:
Protons have a positive (+) charge.
Electrons have a negative (-) charge.
Neutrons have a neutral (0) charge.
I think it should be none of those
The average kinetic energy of a mole of gas can be determined through the equation KE= 1.5 nRT where R is the gas constant equal to <span>8.314 J/K-mol and T is temperature, The temperature for this problem is 125 Kelvin and n is equal to 1 mole. KE then is equal to 1558.88 Joules.</span>
Answer: 1044 kPa
Explanation: To find the total pressure of a system, you add up all the partial pressures. 5.00+4.56+356+678=1043.56, but since you need to account for significant figures it is 1044.
In addition, the amount of significant figures is the number with the smallest amount of decimal places. In this case you have no decimal places, since 356 and 678 have no decimal places. Remember that for the numbers 0-4 you round down and 5-9 you round up.
