The closer the atoms are the more the nitrogen will be come bigger or the oppisite
An element is defined as a substance made up of atoms with a specific number of protons.
Answer:
The root mean squared velocity for CF2Cl2 is 
Explanation:
From the question we are told that
The temperature is 
Root Mean Square velocity is mathematically represented as
Where T is the temperature
MW is the molecular weight of gas
R is the gas constant with a value of 
For CF2Cl2 its molecular weight is 0.121 kg/mol
Substituting values
Answer:
19.4 mL Ba(OH)2
Explanation:
H2(g) + Cl2(g) --> 2HCl(aq) (make sure this equation is balanced first)
At STP, 1 mol gas = 22.4 L gas. Use this conversion factor to convert the 100. mL of Cl2 to moles.
0.100 L Cl2 • (1 mol / 22.4 L) = 0.00446 mol Cl2
Use the mole ratio of 2 mol HCl for every 1 mol Cl2 to find moles of HCl produced.
0.00446 mol Cl2 • (2 mol HCl / 1 mol Cl2) = 0.00892 mol HCl
HCl is a strong acid and Ba(OH)2 is a strong base so both will completely ionize to release H+ and OH- respectively. You need 0.00892 mol OH- to neutralize all of the HCl. Note that one mole of Ba(OH)2 contains 2 moles of OH-.
0.00892 mol OH- • (1 mol Ba(OH)2 / 2 mol OH-) • (1 L Ba(OH)2 / 0.230 M Ba(OH)2) = 0.0194 L = 19.4 mL Ba(OH)2
