Will there ever be grams of a limiting reactant remaining after a reaction has stopped? Why or why not?
Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

1. A student predicted the reaction between hydrogen and oxygen gas would yield 125
mL of water. However, after measuring the water formed in the reaction, the
student determined that only 110mL of water was actually formed. What is the
percent yield of this reaction?
Answer:
88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88
0.88 x 100 = 88%

What geologic process could have formed the channel on Mars?
Answer:
How can we decide which geologic process formed the channel on Mars? Students figure out: The channel on Mars was probably formed by water. The rover Curiosity found rocks near the channel that were made up of many smaller rocks.
Explanation:
Hope it helps! Correct me if I am wrong :>
Can you please mark me as brainlest?
Answer:Water
Explanation:
Water could have formed the channel on Mars because some of the rocks that scientists studied from the earth looks similar to the rocks on Mars.

Which mass is made up of 6.02x10^23 atoms? none of these 23 g sodium 42 g krypton 24 g carbon 78 g potassium
Answer:
23 g sodium
Explanation:
In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).
According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23
Using the formula; mole = mass/molar mass
- Sodium = 23g/23g/mol = 1mol
- Krypton = 42g/84g/mol = 0.5mol
- Carbon = 24g/12g/mol = 2mol
- Pottasium = 78g/39g/mol = 2mol
Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

Match the items to use the analogy of time to the vocabulary of chemistry.
Answer:
1 year- 1 mole
time in general- amount of matter
1 second- 1 atom/ particle
Answer:
1 Year => 1 Mole
Time in General => Amount of Matter
1 Second => 1 Atom/Particle
Explanation:
These pairs make the most sense.

There are two suspects in a shooting investigation. Bullets are recovered from the crime scene. Both suspects own guns, and these guns have been seized by the police. How will the investigators check to see if one of these guns fired the found bullets?
Answer:
They can check if one of the bullets is gone if the gun was fully loaded or they can see if there is any particles of gun powder on the gun. I may be wrong.

In plant cells, how are chloroplasts and mitochondria related?
Answer:
Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.
