Answer:When a bus suddenly starts, the passengers sitting or standing in the bus tend to fall backward. This is due to inertia of rest and can be explained as follows: when the bus suddenly starts, the lower part of the body of the passenger which is in contact with the bus moves along with the bus while the upper part of the body tends to retain its state of rest due to inertia. As a result, the passenger falls backward.

What is the volume of 1.60 grams of O2 gas at STP? (5 points)

tiny-mole [99]

Answer:

1.12 liters

Explanation:

Calculating number of moles

Molar mass of O₂ = 32 g
n = Given weight / Molar mass
n = 1.6/32
n = 0.05 moles

At STP

One mole of O₂ occupies 22.4 L
Therefore, 0.05 moles will occupy :
22.4 L x 0.05 = 1.12 L

To minimize the sharp ph shift that occurs when a strong acid is added to a solution

adell [148]

To minimize the sharp pH shift that occurs when a strong acid is added to a solution, IT IS PRACTICAL TO ADD A WEAK BASE.
When a strong acid is added to a solution, it usually brings about a sharp change in the pH of the concerned solution. To avoid this, one can add a weak base to the solution first. The weak base will serves as a buffer for the strong acid and prevents the solution from experiencing sharp pH variations.
