The substances that will conduct electricity is the NaCl solution. Sodium chloride in its solid form do not conduct electricity since the compound is stable and bonded well so there are no available charge carriers. However, when this salt is dissolved in water, it ionizes or dissociates into sodium ions and chloride ions. On the other hand, solid sugar and an aqueous solution of sugar do not conduct electricity since the bond involved in this compounds is covalent, no ionization would occur. When sugar is dissolved in water it stays as a molecule so there will be no available charge carriers to let electricity flow.
Answer:
When a large, fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma radiation, and free neutrons.
Explanation:
Hope this helps. :)
Ek = (1/2)mv^2
m=7kg
v=4m/s
Ek=(1/2)(7kg)(4m^2/s^2) = 14 kg m^2/s^2
<u>Answer:</u> The number of moles of gas in bicycle tire is 0.210 moles
<u>Explanation:</u>
To calculate the moles of gas, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 737 torr
V = Volume of the gas = 5.30 L
T = Temperature of the gas =
R = Gas constant =
n = number of moles of gas = ?
Putting values in above equation, we get:
Hence, the number of moles of gas in bicycle tire is 0.210 moles
Carbon is a non metal and also has four valence electrons.
