Answer:
Protons, electron, and neutrons
Explanation:
Answer: C
Explanation:
The one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals.
If I'm correct, the crater is actually a circular-shaped area around the volcano's central vent. My answer is false
The molarity of the stock solution of luminol is 1.2 M
<u><em>calculation</em></u>
step 1: find the moles of luminol using (moles= mass/molar mass) formula
molar mass of Luminol= 177 g/mol
moles is therefore= 16.0 g/ 177 g/mol=0.0904 moles
Step 2: find the molarity using (molarity= moles/volume in liters) formula
convert Ml into liters = 75.0/1000= 0.075 L
molarity is therefore= 0.0904 moles/ 0.075 L= 1.2M
Answer:
D
Explanation:
What an interesting amusing question.
The formula for KE = 1/2 m v^2.
v implies that there is motion.
The answer you are looking for is the body of water that has 0 for v.
A cloud moves, so it is not the answer.
A hailstone moves until it hits the ground. I'm assuming it's either on it's way down or it is caught in some sort of updraft in a cumulonimbus cloud. So it has motion.
Same comment for a raindrop. It has a v until it hits the ground so I'm assuming it is not the answer.
I've never seen a puddle of water move. It can only evaporate. So of all your choices, this one (D) is likely the right answer.
