Answer:

In a chemical reaction, arrows separate reactants from products and points to where the reaction is going. On the other hand, the coefficients detail the amount of the components of the chemical reaction.

Explanation:

The way to represent a chemical reaction is through the chemical equation. To write this chemical equation, the following rules must be followed: The reactants are written on the left, and the products on the right, both, separated by an arrow that indicates the direction of the reaction.

The chemical equation must be balanced, leaving the same number of atoms of each of the elements. To balance a chemical reaction, numbers known as coefficients are placed in front of it, showing the relative number of atoms entering a reaction.

The arrows used by chemists means "react to produce" or "yield", such that when two substances react with each other they yield products, represented or shown by an arrow. The coefficients on the other hand, describe the lowest whole number ratio of the amounts of all of the reactants and products.

What mass of Al contains the same number of atoms as 33.5g of Au
wel
Stoich questions...

1) convert the grams of Au to moles
(33.5g)/(196.7g/mol)=___x___

2)find how many atoms are in that many moles by multiplying it by avogadro's number.

x(moles of Au)*(6.02*10^23)=?

3)now that you have found the number of atoms of gold, convert it to grams of aluminum by multiplying it by Avogadro's number and multiplying it by the atomic mass of aluminum.
( ? )(6.02*10^23)(26.98g/mol)= (mass of Al)

If a object has a mass of 10 kilograms, how much does it weigh in newtons?
Len [333]
Depends on where the object is. On earth, moon , or somewhere without any other mass (theoretically). I think you mean how much does weigh on earth. So, the average gravitational acceleration on earth is : 9.83 m/s^2 To find out how much an object weighs, this is the formula : G=m.g where m is mass of the object g is the gravitational acceleration and G is weight. So, G = 10.9,83 = 98,3 N is the answer.

Calculate the molarity of a solution prepared by dissolving 1.495 moles of lioh in enough water to give a final volume of 750. m
zhenek [66]
Molarity can be defined as the number of moles of substance dissolved in 1 L of solution.
In the given question ,
number of LiOH moles - 1.495 mol
Dissolved volume - 750 mL
molarity is calculated for 1 L = 1000 mL
In 750 mL - 1.495 mol of LiOH is dissolved
Therefore in 1000 mL - 1.495 mol / 750 mL x 1000 = 1.99 mol
