They need to replicate the experiment to see if the found data is relaible and consistent. #TeamAlvaxic
Answer:
Explanation:
Molarity = moles/liters of solution
moles = molarity x Liters of solution
= 0.350 m/L x 0.855 L
= 0.299 mol
mass = moles x molar mass
= 0.299 mol x 102.89 g/ms
= 30.78 grams
Answer: The loose objects will tend to move to the right inside the car.
Explanation:
The options include:
A. The loose objects will tend to move to the left inside the car.
B. The loose objects will tend to move to the right inside the car.
C. The loose objects will tend to move toward the front of the car.

Based on the question, we are informed that Mary is driving on a straight road and then a deer jumps in front of her, which made her turn her car sharply to the left.
The loose objects inside the car will move towards the opposite direction. Since Mary made a left turn, the loose objects in the car would move to the right.
Answer:
.081 g of O2
Explanation:
4Cr + 3O2 -----> 2Cr2O3
.175 g Cr x [1 mole / 52.0 g] x [2 moles Cr2O3 / 4 moles Cr] x [152 g / 1 mole] = .256 g of Cr2O3
.175 g Cr x [1 mole / 52.0 g] x [3 moles O2 / 4 moles Cr] x [32 g / 1 mole] = .081 g of O2
