Two objects are described below.
mojhsa [17]

Answer:

Both objects are moving.

Explanation:

Object 1 is moving because the unbalanced force acting on the skateboard is causing it to <em>either move slower or move faster.</em> An example of this is when the skateboard is going down the hill. The unbalanced force is caused by the gravity which speeds up the skateboard.

Object 2 is also moving although it has a balance force; however, it is moving at a<em> "constant speed."</em> This is because the force of thrusting forward is being counteracted by a friction force of the <u>same magnitude.</u> Forces that are equal in magnitude and of opposing directions causing the speed to be constant. So, the bicycle is still moving.

Dovator [93]

Answer:

5 × 10^-4 L

Explanation:

The equation of the reaction is;

2KClO3 = 2KCl + 3O2

Number of moles of KClO3 = 13.5g/122.5 g / mol = 0.11 moles

From the stoichiometry of the reaction;

2 moles of KClO3 yields 3 moles of O2

0.11 moles of KClO3 yields 0.11 × 3/2 = 0.165 moles of oxygen gas

From the ideal gas equation;

PV= nRT

P= 85.4 × 10^4 KPa

V=?

n= 0.165

R= 8.314 J K-1 mol-1

T= 40+273 = 313K

V= 0.165 ×8.134 × 313/85.4 × 10^4

V=429.4/85.4 × 10^4

V= 5 × 10^-4 L
