Remember this---> parts over whole
we need to find the total mass first-- > 12.0 grams + 32.0 grams= 44.0 grams
O%= part of oxygen / whole ----> 32.0/ 44.0 x 100= 72.7 %
F because it NEVER forms any cations in chemical reactions
(NO3)2+H2O+NO that is the answer
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
