Answer:
The first two options are correct
Explanation:
The first two options are part of the benefits of a parallel connection of bulbs in a circuit. Here, the voltage of each connecting bulb is the same as the voltage of the bulb in the circuit hence all the bulbs have the same voltage running through them. Thus, when one bulb is removed/burns out, it does not affect the remaining bulbs (those ones will remain lit). Also, the addition of bulb(s) does not cause the remaining bulbs in the circuit to get dimmer (since they will all have the same voltage).

Let's do it like this...
The question says write a balanced equation for the reaction between aqueous lead(II) nitrite and aqueous potassium chloride to form solid lead(II) chloride and aqueous potassium nitrite...
Analysising
________________________________________________________
Aqueous Lead(II) Nitrate written as a Formula is Pb(NO3)2 and Aqueous potassium written as a Formula is KOH.......and.......here the statement says they form Solid lead(ll) chloride which is PbCl₂ and aqueous potassium nitrite which is KNOH3
so The unbalanced equation will be
Pb(NO3)2 + KCL ====> PbCl2 + KNOH3
________________________________________________________
New Balanced Equation
________________________________________________________
Pb(NO3)2 + 2KCL ====> PbCl2 + 2KNOH3
(Balanced) RHS = LHS
Explanation:
Balancing The Equation
Lead (Pb) Has a coefficient of 1 both side.(Balanced)
Nitrate (NO3) has 2 as their coefficient both sides. (balanced)
Potassium (K) has a coefficient of 2 in the left so in the right. (balanced)
Chlorine (Cl) has also a coefficient of 2 in the right so in the left. (balanced)
Therefore the equation is balance the LHS equals to the RHS
NB : There's no any balanced equation than this

Answer:
Explanation:
Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. Here follows the most common kinds of variation.
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. In the following equation y varies directly with x, and k is called the constant of variation:
y=kx
Another form of variation is the inverse variation which works when there is a relationship between two variables in which the product is a constant. When one variable increases the other decreases in proportion so that the product is unchanged.
