Opposite pairs form ionic bonds, due to this the answer is D - Li and Br; They have unlike charges.
Answer:
i'd say the second choice.
Explanation:
the rise in temperature causes the particles to vibrate causing motion. they collide thus resulting to the weakening of the particles.
hope it is of use to you.

The Balance Chemical Equation is as follow,
2 HCl + Pb(NO₃)₂ → 2 HNO₃ + PbCl₂
According to equation,
331.2 g (1 mole) Pb(NO₃)₂ produces = 278.1 g (1 mole) PbCl₂
So,
870 g of Pb(NO₃)₂ will produce = X g of PbCl₂
Solving for X,
X = (870 g × 278.1 g) ÷ 331.2 g
X = 730.5 g of PbCl₂
Therefore,
Theoretical Yield = 730.5 g
Also as given,
Actual Yield = 650 g
So using following formula for percentage yield,
%age Yield = (Actual Yield / Theoretical Yield) × 100
Putting values,
%age Yield = (650 g / 730.5 g) × 100
%age Yield = 88.98 %

<span>s sublevel = s orbital
p sublevel= p orbitals
the level tells you which orbitals exactly,
so level 3,
sub level p = 3p orbitals </span>
