Answer:
Explanation:
We can use the formula for momentum to calculate the mass.
Answer:2 Li+CO2+H2O=LiHCO3+H2
Explanation:
Explanation:
Formula to calculate the atomic packing factor is as follows.
APF =
=
It is given that atomic radius is 0.123 nm and density of metal is 7.45 .
Hence, number of atoms will be calculated as follows.
No. of atoms = = 4
APF =
= 1.3905
Thus, we can conclude that atomic packing factor if the unit cell has a tetragonal symmetry is 1.3905.
Answer: -
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
Explanation: -
The mass number for ¹³C = 13
The atomic number for ¹³C = 6
Number of electrons present in ¹³C = atomic number = 6
Number of protons present in ¹³C = atomic number = 6
Number of neutrons present in ¹³C = mass number - atomic number = 13 - 6 = 7
For ¹³C ⁻ ion,
Number of electrons present = 6 + 1 = 7
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
Answer:
2NaOH + 2Al +2H2O = 2NaAlO2 +3H
Explanation:
Aluminum is an amphoteric element it reacts with both bases and acids to form a salt and hydrogen gas.The reaction is highly exothermic.
