Answer: it would be D
Explanation:
A moving average trendline uses a specific number of data points averages them, and uses the average value as a point in the trendline. If Period is set to 2, for example, then the average of the first two data points is used as the first point in the moving average trendline.
5- sr +2 O -2. SrO
6- Mg +2 F-1 MgF2
7- B+3 P-3 BP
8- Li +1 N-3 Li3N
9- Ba +2 Br -1 BaBr2
10- Al +3 P -3 AlP
Answer: B. The molecules move faster and become less dense
Explanation:
Liquid is the state of matter in which particles are less tightly bound as compared to solids as they have weak inter molecular forces as compared to solids.
Thus when a solid is heated, the molecules start moving in random motion due to an increase in the kinetic energy. The molecules move apart as the forces will be weak and thus less molecules will be present per unit volume. Thus it will become less dense.
