Answer:

Gravitational force decreases

Explanation:

One of Newton's remarkable discoveries was the law of universal gravitation, according to which if two bodies have mass, when they are close to each other there is a force of attraction between them. Thus, for example, the Earth attracts the Moon and the Sun to the Earth. For our purposes, the important thing about this law is that it tells us, first of all, that the force between the bodies depends on the distance between them. It does not matter to have two bodies very close to each other that are very separate. The greater the distance between the bodies, the smaller the force between them, since as the distance between two bodies is greater, the smaller the effect that one exerts on the other.

Second, the law of universal gravitation tells us how the force of distance depends. Suppose two bodies are at a distance of one meter and the force has a certain value. If the distance between these same bodies increases twice, that is to 2 m, then the force decreases to a quarter. If the distance increases to triple, that is to 3 m, the force decreases to the ninth part, and so on.

The fourth part of the force is equal to 1/4; but 4 = 2², that is, 2 raised to power 2; So the fourth part is equal to 1/2.

The ninth part of the force is equal to 1/9; but 9 = 3², that is, 3 raised to power 2; So the ninth part is equal to 1 / 3², etc. Consequently: if the distance increases 2 times, the force decreases 1/2 times; if the distance increases 3 times, the force decreases 1 / 3² times; if the distance increases 4 times, the force decreases 1/4 times, and so on.

The latter is expressed by saying that the decrease in the value of the force is like the square of the distance. In abbreviated form, u<u>sing mathematical language the above is expressed by saying that force depends inversely proportional to the square of distance. Conversely it means that increasing distance decreases force</u>

1. Balance the equation, then answer the following based on the equation
Artemon [7]

Answer:

Q1. a) 4Al + 3O₂ ➟ 2Al₂O₃

b) 7.4 moles

c) 11.1 moles

Explanation:

To balance an equation, ensure that the total number of atoms of each element on both sides are equal.

Al + O₂ ➟ Al₂O₃

On the left side of the arrow, you would find the reactants while the product(s) is found on the left hand side.

<u>Reactants</u>

Al atoms: 1

O atoms: 2

<u>Product</u>

Al atoms: 2

O atoms: 3

After balancing,

4Al + 3O₂ ➟ 2Al₂O₃

We have 4 Al atoms and 6 O atoms on both sides.

b) The balanced equation tells us the mole ratio of Al to Al₂O₃.

Al: Al₂O₃

= 4: 2 (÷2 throughout)

= 2: 1

This means that for every 1 mole of Al₂O₃, 2 moles of Al is needed.

Since we need 3.7 moles of Al₂O₃,

number of moles of Al needed

= 2×3.7

= 7.4

c) 4Al + 3O₂ ➟ 2Al₂O₃

For every 4 moles of Al, 3 moles of O are needed.

For each mole of Al,

number of moles of O needed

= 3÷4

= 0.75

For 14.8 moles of Al,

number of moles of O required

= 0.75 ×14.8

= 11.1

Which way does equilibrium shift
Natali [406]
You can use Le Chatelier's Principle to describe the equilibrium shift.

Le Chaterlier's Principle states that: "<span>If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change."

Thus, if you heat up the reaction, the equilibrium shift favors the endothermic reaction. If you increase pressure (if gases are involved), the shift favors the reaction that produces less gaseous products (to counteract pressure) and so on.</span>

Calculate the molarity of a solution obtained dissolving 10.0 g of cobalt(Ⅱ) bromide tetrahydrate in enough water to make 450 mL
Vladimir [108]

Answer:

<em><u>The molarity of the CoBr2•4H2O solution is  7.64 × 10-2 M</u></em>

Explanation:

Cobalt (II) bromide tetrahydrate

• Cobalt - A transition metal with Roman numeral (II) → charge: +2 → Co2+

• Bromide - anion from group 7A → -1 charge → symbol: Br-

• Tetrahydrate- tetra- means 4 and hydrate is H2O

The chemical formula of the compound is: CoBr2•4H2O

We then need to determine the number of moles of CoBr2•4H2O since this is the only information missing for us to find molarity. Notice that the volume of the solution is already given.

We’re given the mass of CoBr2•4H2O. We can use the molar mass of CoBr2•4H2O4 to find the moles.

•The molar mass of CoBr2•4H2O is:

CoBr2•4H2O  

1 Co x 58.93 g/mol Co = 58.93 g/mol

2 Br x 79.90 g/mol Br = 159.80 g/mol

8 H  x 1.008 g/mol H = 8.064 g/mol

4 O  x 16.00 g/mol O = 64.00 g/mol

________________________________________

                           Sum = <u>290.79 g/ mo</u>

The moles of CoBr2•4H2O is:

= 10.0 g CoBr2•4H2O x  \frac{ 1 mol  CoBr_2 . 4H_2O}{290.79 g CoBr_2 .  4H_2O}

= <u>0.0344  mol CoBr2•4H</u>

We know that the volume of the solution is 450 mL.

We can now calculate for molarity:

Convert mL to L → 1 mL = 10-3 L

Formula:

Molarity (M)= Mole of solute / Liters of solution

= 0.0344  mol CoBr2•4H  / 450 mL x 1 ml / 10^ -3 L

= 0.0764

=  7.64 × 10-2 mol/L
