Answer:
B. Chemical changes produce new substances; physical changes do not.
Explanation:
Physical changes only alter appearances, while chemical changes are interactions that create new chemical formulas.
The number of protons defines what element it is and also determines the chemical behavior of the element.
Answer: The charge on the plates are 88.4 picafarad
Explanation:The equation used in measuring charge in a plate is given as:
C=Q/V =E A/D
Where E= dielectric content
A= Area of plates
d= distance between plates
Using dielectric constant for Air=8.84×10-12F/m
A=100cm2=0.01m2
d=10mm=0.001m
C= 8.84×10-12×0.01/0.001
C= 88.4 picafarad
<span>Chemical formulas are written from the most metllic
for example group Alkali Metals are the most metallic, so they will be written first.</span>
