The water molecules are moving so slow that they end up sticking together to form a solid
Answer:
Quantum mechanics or physics
Explanation:
Answer:
M = 1.04 M
Explanation:
Given data:
Molarity of solution = ?
Mass of HCl = 6.27 g
Volume of solution = 163 mL (163 mL× 1L /1000 mL = 0.163 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of HCl:
Number of moles = mass/molar mass
Number of moles = 6.27 g / 36.5 g/mol
Number of moles = 0.17 mol
Molarity:
M = 0.17 mol/ 0.163 L
M = 1.04 M
Answer:
The answer to your question is:
atomic number (Z): 6
mass number (A) : 13
Explanation:
Carbon has an atomic number of 6 and a mass number of 12,
Mass number = # protons + # neutrons
12 = 6 + # neutrons
#neutrons = 12 - 6 = 6
For the carbon isotope the atomic number does not change is still 6
13 = 6 + # neutrons
# neutrons = 13 - 6
# neutrons = 7
Answer:
1 that is 100%
Explanation:
here it is given that Fermi energy of the of the metal = 5 e.V
work function= 4 e.V
we have to find the probability that an incident electron will tunnel out if E=109 V/m
WORK FUNCTION : work function is defined as the energy required to withdraw an electron completely from the metal surface.
now the energy per unit volume in electric field is given by
E= 
E=
E=
in electron volt E=4.427\times 10^{6}joule × 6.24\times 10^{18}
E=
hence the applied energy per unit volume is greater than the work work function of electron so there is probability of 100% that electron will tunnel out
