I don't know what you are talking about but if you are asking about the difference between <span>electric discharge and electric current then;</span>
The electric current is the amount of electrons or charges passing through a conductor per units of time. 1 ampere = 1 coulombs / 1 second.
Electric discharge is the consequence of disrupting an isolator (for example, air), thus causing a sudden flow of electricity.
Answer:
2.567
Explanation:
To change milliliters into liters you divide by 1000
So when you divide 2567 by 1000 you get 2.567
Answer:
6.92; neutral
Explanation:
Kw = [H^+][OH^-] = 1.47 × 10^-14
pKw = pH + pOH = 13.83
At neutrality, [H^+] = [OH^-] and pH = pOH
2pH = 13.83
pH = 6.92
The pH will be 6.92.
At 303 K, this will be the neutral pH, because [H^+] = [OH^-]
The answer is 'lipids'
hopefully this helps
Answer:
3.1 moles of ammonia
18.67× 10²³ molecules
Mass = 52.7 g
Explanation:
Given data:
Number of atoms of hydrogen = 5.68×10²⁴ atoms
A) Number of molecules of ammonia = ?
Solution:
First of all we will calculate the number of moles of hydrogen.
1 mole = 6.022× 10²³ atoms
5.68×10²⁴ atoms × 1 mol / 6.022× 10²³ atoms
0.94×10¹ mol
9.4 moles of hydrogen
Moles of ammonia:
3 moles of hydrogen are present in one mole of ammonia.
9.4 moles of hydrogen = 1/3×9.4 =
3.1 moles of ammonia
Number of molecules of ammonia:
1 mole contain 6.022× 10²³ molecules.
3.1 mol × 6.022× 10²³ molecules / 1 mol
18.67× 10²³ molecules
c) Mass of sample = ?
Mass = number of moles × molar mass
Mass = 3.1 moles × 17 g/mol
Mass = 52.7 g
