Answer:
K₂O +2Li --> Li₂O +2K
Explanation:
On the left side, K has 2 atoms and O has one combines with Li having 2 atoms. When the process starts Li burns and got atoms from O.
Hence O has 2 ions and Li has 1 ion
so to complete the bond, Two Li will have 2 ions which can complete O by sharing his 2 icons. i.e. Li₂O
and Two atoms of K can exist like 2K
So the equation will be like
K₂O +2Li --> Li₂O +2K
Answer:magnesium plus nitrogen is : magnesium nitride
Explanation:
Boyle's Law
G: V1= 130 mL
P1= 0.97 atm P2= 1 atm (standard pressure)
U: V2=?
F: V2 = V1 P1/P2
S: V2 = (130 mL) (0.97 atm) / 1 atm
Answer : V2 = 126.1 mL volume of the gas occupy @ STP
Answer: T2= 962.2 K
Explanation:
The ideal gases is often written like PV=nRT, where P is pressure, V is volume, n is moles, R is the universal constant of the gases and T is Temperature.
So, in this problem there is a container that is a closed system, therefore n is constant and volume too. The initial point is 1 and the final point is 2, so
V1=V2 ⇒

Spring a has more potential energy then spring b
