Assume there are 100 g of the substance.
Masses:
Si: 46.8 g
O: 53.2 g
Moles:
Si: 46.8 / 28 = 1.67
O: 53.2 / 16 = 3.32
Dividing by the smaller number:
Si: 1.6 7/ 1.67 = 1
O: 3.32 / 1.67 = 2
Thus, the formula:
SiO2
The person who discovered universal gravitation was newton.
Given,
P1 = 0.98 atm
V1 = 0.5 L
V2 = 1.0 L
P2 = ?
Solution,
According to Boyle's Law,
P1V1 = P2V2
0.98 × 0.5 = 1.0 × P2
P2 = 0.98 × 0.5 × 1.0
P2 = 0.49 atm
Answer - The new pressure is 0.49 atm.
Answer:velocity of molecules within a body
Explanation:
Temperature is defined as the average kinetic energy of the molecules of a body. The kinetic energy of a body depends on the velocity of the molecules of the body. When the temperature of a body increases, its particles acquire greater kinetic energy and move at higher velocity. Hence temperature depends on the velocity of the molecules of a body while heat is a form of energy.
Answer:
TRUE
Explanation:
remember newtons laws of motion. Every action has an equal and opposite reaction. LOL
