Answer:
Jose is right
Explanation:
As the book is sitting still on the table, it is being acted upon by two forces of equal magnitude and opposite direction. Theses are;
i) The weight of the book
ii) The normal reaction on the book
The weight of the book acts downwards while the normal reaction acts upwards. These two forces exactly counterbalance each other hence the book sits still on the table.

1.List one extensive and one intensive property of marker ink.
Intensive property is a property that is independent of the amount of sample such as the color of the ink. Extensive property is the opposite which is dependent to the amount such as volume.
2.Define mixture.
Mixture is a system that contains two or more substances which are agitated but not chemically bonded.
3.Is tap water a heterogeneous or homogenous mixture?
Tap water is a homogenoeus mixture because it has uniform properties in every sample you get.
4.Is isopropyl alcohol (rubbing alcohol) a heterogeneous or homogenous mixture?
I think the rubbing alcohol is a homogeneous mixture since it has uniform properties as well.
1) Use the fact that 1 mol of gas at STP occupies 22.4 liter
=> 1 mol / 22.4 l = x / 0.125 l => x = 0.125 l * 1 mol / 22.4 l = 0.00558 mol
2) Now use the molar mass of the gas
molar mass of CO2 ≈ 44 g / mol
Formula: molar mass = mass in grams / number of moles =>
mass in grams = molar mass * number of moles = 44 g/mol * 0.00558 moles
mass = 0.246 g
Answer: 0.246 g
