A. only volume (cm^3)

Explanation:
The independent variable is typically represented as x. It is the variable that you change during the experiment. In this graph, as volume increases, it increases the mass too. Hope this helps!

How many grams of aluminum is produced when 82.4 grams of aluminum chloride
yKpoI14uk [10]

Answer:

16.6 g of Al are produced in the reaction of 82.4 g of AlCl₃

Explanation:

Let's see the decomposition reaction:

2AlCl₃ →  2Al  + 3Cl₂

2 moles of aluminum chloride decompose to 2 moles of solid Al and 3 moles of chlorine gas.

We determine the moles of salt:

82.4 g . 1mol/ 133.34g = 0.618 moles

Ratio is 2:2. 2 moles of salt, can produce 2 moles of Al

Then, 0.618 moles of salt must produce 0.618 moles of Al.

Let's convert the moles to mass → 0.618 mol . 26.98g /mol = 16.6 g

The gravitational force between which two objects would be the most difficult to notice? A. The moon and the earth b. The moon a
Ghella [55]

Answer:

d. A water particle and an air particle

Explanation:

The force of gravity (F) between two objects of masses m1 and m2 and separated by a distance r is given as:

F = G\frac{m1*m2}{r^{2} }

where G is the gravitational constant

This force is therefore, directly proportional to the masses and inversely related to the distance between them.

Based on the given options, since the masses of the water and air particles are very small (masses of earth, moon and sun is relatively huge), the gravitational force between them would be negligible and difficult to measure.
