Answer:
I THINK 25,000 CG CONVERTS TO 250G
Explanation:
also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1). The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutron in the nucleus.
Answer : The partial pressure of nitrogen gas in the mixture is, 9.88 atm
Explanation :
According to the Dalton's Law, the total pressure of the gas is equal to the sum of the partial pressure of individual gases.
Formula used :
where,
= total pressure of gas = 13.6 atm
= partial pressure of helium gas = 1831 torr = 2.41 atm
= partial pressure of argon gas = 997 torr = 1.31 atm
Conversion used: (1 atm = 760 torr)
= partial pressure of nitrogen gas = ?
Now put all the given values in the above formula, we get:
Thus, the partial pressure of nitrogen gas in the mixture is, 9.88 atm
Answer is: A. covalent bonds.
Insulator most likely has covalent bonds, because it must have low electrical conductivity.
1) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.
2) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.
3) Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
