Answer 2

Answer:

0.05  moles

Explanation:

In a mole of any substance, there exist 6.02

⋅   10

^23 units of that substance.

So here, we got:

3.01 ⋅ 10^22 Mg atoms ⋅ 1 mole / 6.02 ⋅ 10^23 Mg atoms

= 0.05  moles

Hope that helps!

Liquid water (H2O) is formed when two gases, hydrogen (H2) and oxygen (O2), react. Why are the properties of water different than those of the reactant gases?

Answers

Answer:

Liquid water (H2O) is formed when two gases, hydrogen (H2) and oxygen (O2), react. ... The difference in the properties of water can be attributed to physical changes to the hydrogen and oxygen atoms on a subatomic level. The properties of the gases are combined to give water its properties.

identify ways to reduce the risk of liquid bumping while heating.

Answers

The most common way of preventing bumping is by adding one or two boiling chips to the reaction vessel. However, these alone may not prevent bumping and for this reason it is advisable to boil liquids in a boiling tube, a boiling flask, or an Erlenmeyer flask.

Look at the window on the left side of the simulation. It shows the reaction A + BC ⇌ AB + C. How does this reaction differ from the reaction by which ammonia is synthesized?

Answers

Answer:

A + BC → AB + C "single replacement reaction" while ammonia synthesis is a "synthesis reaction".

Explanation:

A single replacement reaction, is a reaction by which one element replaces an/other element in a compound.

It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The reactants may be elements or compounds, while the product is always a compound.

Example: ammonia synthesis,

N₂ + 3H₂ ⇄ 2NH₃

When forming an ionic bond, how does the configuration of valence electrons change

Answers

Answer:

Ionic bonds are a class of chemical bonds that result from the exchange of one or more valence electrons from one atom, typically a metal, to another, typically a nonmetal. This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond.

Explanation:

Answer:

The electrons are transferred from one atom to another. The atom that loses electrons becomes positive.

Cual es el %en masa de una disolución de 30g de azucar en 70g de agua

Answers

La fórmula para averiguar un % en masa es:
% en masa de soluto = masa de soluto · 100
masa de disolución

:
% en masa de soluto = 30 (g de azúcar) · 100 = 3000g = 30g.
100 (g de disolución) 100g

30g es el % en masa de una disolución preparada con 30 g de azúcar en 70 g de agua.

ILL GIVE YOU BRIANLIEST! PLEASE HELP: Every compound is a molecule, but every molecule is not a compound. Why is this? Give an example with your answer.

This is because some molecules contain only one chemical element, and a compound, by definition, contains 2 or more elements.

Explanation:

Consider molecular Hydrogen (H₂) as an example. It is a molecule, albeit very simple, because it is made up of multiple atoms (2 Hydrogen atoms, to be precise). It is not a compound, however, because it only contains one chemical element: Hydrogen.

Lead has a density of 11.4 grams per mL. If I make a statue out of 3.78 grams of lead, what is the statues volume

Answers

Answer:

0.332mL

Explanation:

11.4g/mL is 11.4 for every one mL

11.4g / 1mL needs to be the same ratio as 3.78g to an unknown value, let's call it x.

11.4g/1mL = 3.78g/x

We cross multiply: 1*3.78 = 11.4*x

3.78 = 11.4x

Now isolate x by diving 11.4 on both sides: 0.331578974mL = x

In chemistry, we usually round to significant figures, so our answer would be 0.332mL

Why does the total mechanical energy stay the same as kinetic and potential energy change?

Answers

total mechanical energy is the sum of kinetic energy and potential energy so it will remain same always

Answer:

Explanation:

Because the kinetic and potential energy are constant. A good example of kinetic and potential energy are throwing a ball up. It leaves your hand with kinetic energy. When it reaches the top it doesn’t have any kinetic force but potential energy equal to the kinetic energy the ball had when you threw it up. And, when it comes back to your hand it has the same kinetic energy it had when it left your hand. Thus, the sum of the kinetic energy plus potential energy is a constant.
