Sp^3d hybridization means that there is a total of 5 electron regions, with two lone paid, the molecular shape would be T-shaped
That would be BaSO4(s) ( s means solid)
Answer:
165 ml
Explanation:
We are given;
Initial volume; V_a = 55 ml
Initial molarity; M_a = 3 M
Molarity of desired solution; M_b = 0.75 M
Volume of desired solution; V_b = (55 + x) ml
Where x is the volume of water to be added.
To solve for V_b, we will use the equation ;
M_a•V_a = M_b•V_b
V_b = (M_a•V_a)/M_b
V_b = (3 × 55)/0.75
V_b = 220 mL
Thus;
(55 + x) = 220
x = 220 - 55
x = 165 mL
Answer:
Chemical equilibrium is also called as dynamic equilibrium because it in chemical equilibrium, the equilibrium can shift towards both sides that is reactant and product known as equilibrium shifting. And in chemical equilibrium, the reaction is going on but the rate of formation of reaction is equals to the rate of formation of product.
Hope this helps!
Answer:
2040 cm-1
Explanation:
The vibrations frequency is obtained from;
v=1/2πc √k/μ
Where;
k= force constant = 240kgs-2
μ= reduced mass = 1.627×10^-27 kg
c= speed of light= 3×10^10cms-1
v= 1/2×3.142×3×10^10√240/1.627×10^-27
v= 5.3×10^-12 × 3.84×10^14
v= 20.4×10^2
v= 2040 cm-1
