1. What is the potential energy of a 8 kg ball that is at a height of 20 m?
weqwewe [10]

Answer:

1. 1568 J

2. 0 J

3. 1176 J

Explanation:

PE = mgh

(PE = Potential Energy) = (m = mass)(g = gravitational force which is 9.8)(h = height)

1. (3)(9.8)(20) = 1568 J

2. PE = (3)(9.8)(0) = 0 J

3. (5)(9.8)(24) =  1176 J

46g of a mineral contained 16g copper, 14g iron and 16g sulphur. Calculate the empirical
pochemuha

Answer:

CuFeS2

Explanation:

Calculate the moles of each substance by doing moles= mass/relative atomic mass. you should get 0.25 moles of copper and iron and 0.5 moles of sulfur. Then divide all of those numbers by 0.25 (as its the lowest value) you should get 1 for copper and iron and 2 for sulfur. This represents the ratio that they are in within the mineral.

A solution has 500 mL and contains 0,5 moles of AlCl3. What is its molarity?
deff fn [24]

Answer:

The molarity is: 1 M

Explanation:

We define molarity as an amount of moles in 1000ml of solution (1 liter)

500ml---------0,5 moles AlCl3

1000ml------x= (1000ml  x 0,5 moles AlCl3)/500ml = 1 moles ACl3--> 1 M
