Lithium: 0.98
beryllium: 1.57
boron:2.04
carbon:2.55
nitrogen:3.04
lithium is the answer. it means that the atoms in the left side of the periodic table have the lowest electronegativity value
and the right side atoms have the highest
hope this helps
Answer: Methylamine when heated with an alcoholic solution of KOH and CHCl3CHCl3, it gives an offensive smell of methyl cyanide.
Explanation:
Answer:
10mL
Explanation:
Using the formula as follows:
CaVa = CbVb
Where;
Ca = concentration of acid, HBr (M)
Cb = concentration of base, Sr(OH)2 (M)
Va = volume of acid, HBr (Litres)
Vb = volume of base, Sr(OH)2 (Litres)
According to the information given in this question;
Ca = 0.24M
Cb = 0.24M
Va = ?
Vb = 10.0ml
Using CaVa = CbVb
0.24 × Va = 0.24 × 10
0.24Va = 2.4
Va = 2.4 ÷ 0.24
Va = 10mL
10mL of HBr is needed.
Answer:
The Equilibrium will shift to the left.
Explanation:
The reaction at equilibrium is as follow,
CH₃COOH ↔ CH3COO⁻ + H⁺
According to Le Chatelier's Principle," When a system (reaction) at equilibrium is subjected to any stress (like change in Concentration, Pressure, Temperature e.t.c) the system (reaction) tends to adjust itself in such a way so as to minimize the effect of that change".
Hence, in above reaction when Sodium Acetate (source of CH₃COO⁻) is added the equilibrium will shift in left side and will decrease the concentration of CH₃COO⁻ions.
How do you find volume at STP? It can be written as: V = nRT/P. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature. Record the molar gas constant “R”.
