because they have delocalized electrons
Answer:
1 mole
Explanation:
The mole (mol) is the amount of a substance that contains the same number of entities as there are atoms in exactly 12 g of carbon-12. One mole (1 mol) contains 6.022x1023 entities (to four significant figures).
Physical properties are describing the object.
-White
-Grainy
-Small
-Sweet
etc.
Answer:
K.E = 19125 j
Explanation:
Given data:
Mass = 150 Kg
Speed of car = 15 m/s
K.E = ?
Solution:
Formula:
K.E = 1/2 (mv²)
K.E = Kinetic energy
m = given mass
V = speed
now we will put the values in formula.
K.E = 1/2 (mv²)
K.E = 1/2 (150 Kg) (15²)
K.E = 1/2 150 Kg × 225 m²/s²
K.E = 0.5 × 225 m²/s² ×150 Kg
K.E = 19125 j
