C-Cl bond is polar.
As Cl is more electronegative than C,
Cl pulls the shared electrons towards its side making the C-Cl bond polar.
Polar meaning C gets a partial positive charge and Cl gets a partial negative charge. Thus C-Cl bond becomes polar.
CCl4 molecule is tetrahedral.
And its shape is symmetrical.
That means its similar on all corners or all planes and it can be cut into equal halves from any plane.
C-Cl bond is polar.But the C-Cl polairty gets cancelled out as its pulled equally from all sides.
Since the molecule is symmetrical CCl4 is non polar.
Can you take picture of the whole question? I can’t see.
KE=3070.625 J
Height = 3.686 m

mass of bike+rider=85 kg
velocity = 8.5 m/s
Conservation of energy :
(KE+PE)₁ (downhill) = (KE+PE)₂ (up the hill)
PE₁=0⇒h=0
KE₂=0⇒v=0(stop), so equation becomes :
KE₁=PE₂
Answer:
Correct option: A
Explanation:
Equilibrium means the state of reaction which there is no net changes occur it means the rate of forward reaction and rate of backward reaction become same and also it does not mean that the concentration of both side i.e. reactant and product become equal. after gaining equlibrium position the concentration of reactant and product remain same and also chemical reaction does not stop and it continues.
Answer:
8.324 g
Explanation:
First we <u>convert 750.0 mL into L</u>:
- 750.0 mL / 1000 = 0.750 L
Then we <u>calculate the required number of moles of CaCl₂</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- Molarity * liters = moles
- 0.100 M * 0.750 L = 0.075 mol
Finally we <u>convert 0.075 moles of CaCl₂ into grams</u>, using its <em>molar mass</em>:
- 0.075 mol * 110.98 g/mol = 8.324 g
