Answer:
Using the proportions of the amount of the molecules, we can convert from any reagent or product to any other reagent or product. In the context of this reaction, for every mole of N2 and every 3 moles of H2 we obtain 2 moles of NH3.
Explanation:
Hydrogen is the limiting reactant. In other words, Hydrogen will run out before Nitrogen because it takes 3 mole of H2 and just 1 mole of N2 to make 2 mole NH3. What is the greatest amount of MgO (in moles) that can be made with 7.8 moles of Mg and 4.7 moles of

how does newton’s third law effect bowling?
Answer:
The bowling ball will remain in motion until an unbalanced force acts on the bowling ball. ... When the ball hits the pins, they push on the ball with the same amount of force in the opposite direction. This means that the ball will slow down, and the pins will fall, which is the reaction.
Explanation:
Answer: His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.
Explanation: this means that when you throw the ball the wind pushes against the ball and so does the bolling pints.

When vinegar is added to baking soda, Carbon dioxide is formed. Name the reactant(s) and product(s)
(Earn 15 points)
Answer: The "equation" here is vinegar + baking soda = carbon dioxide. The reactants are vinegar and baking soda. The products are carbon dioxide.
Explanation: The reactants are the "ingredients," or the two or more substances you mix in order to form the product, the ending result. In this situation, you mixed vinegar and baking soda, so those are the reactants. You ended up making CO2, the product.

How many moles contain 9.15 x 1022 atoms of Ag?
Select the correct response.
0.152 mol
9.15 mol
0.325 mol
5.51 mol
Answer:
0.152 molExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{9.15 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.151993...[/tex]
We have the final answer as
0.152 molesHope this helps you

Consider the compound Al(OH)3. What type of
solid does it form?
crystal lattice
glass
metal
molecule
Answer:
crystal lattice
Explanation:
The Aluminium Hydroxide forms a crystal lattice solid structure, the correct option is A.
What is a Crystal Lattice?The symmetrical, three-dimensional structural configuration of points representing atoms, ions, or molecules that make up a crystalline material is known as the crystal lattice.
It can be described as the geometrical arrangement of the crystalline solid's atoms, ions, or molecules as points in space.
Al(OH)3 is called Aluminium hydroxide, It is found in nature as the mineral gibbsite.
It is an amorphous white powder and is insoluble in water but soluble in acidic and alkaline solutions.
It can be used to relieve indigestion and stomach discomfort.
Al(OH)₃ is composed of two layers of hydroxyl groups, with aluminum ions filling two-thirds of the octahedral holes in the center of the structure.
There are four identified polymorphs. Each has layers of octahedral aluminum hydroxide units connected by hydrogen bonds.
So, the solid form of the compound Al(OH)₃ has a crystal lattice structure.

Like Gravity, electrostatic forces always attract
An atom with an equal number of protons and electrons can pull with an electrostatic force
An ion with a negative charge will repel another ion with a negative charge
Electrostatic forces are a fundamental force in the universe
Answer:
Option 3 or C An ion is all in Electrostatic forces so it's c if its not I'll work it out for you
An ion with a negative charge will repel another ion with a negative charge is the correct statement.
What is electrostatic forces?The electrostatic force is the force that exists between electrically charged particles or objects at rest means that objects having similar charge repel each other whereas objects having different charges attract each other.
An ion with a negative charge will repel another ion with a negative charge is the statement true about electrostatic forces because electrostatic force always occur between static object having charges on it.
