M/V=D
40.5/15=2.7
The density of the block of aluminum is 2.7 g/cm³.
A 3p orbital has one planar node perpendicular to the orbital's axis, and one radial node.
Outcome (dependent) variable-drinking energy drinks
Test (independent) variable- more aggressive
Mass = 5 g
volume = 20 cm³
density = mass / volume
therefore:
D = m / V
D = 5 / 20
D = 0.25 g/cm³
Answer:
2 and 4
Explanation:
The rest of the changes are chemical. 1 has a chemical reaction happen which makes light sticks glow. 3 is because browning the meat actually causes some new compounds to form and cause caramelization.
For 2, the oxygen is simply heating up and expanding which pops the balloon. 4 is just a phase change of water vapor to liquid water.
