What mass of PCl5 will be produced from the given masses of both reactants which is 839 moles of P4 and 316 moles of Cl2 Answer needs to be submitted in grams though please?
Our lower number of moles is .316 so we will use that. The total molar mass of PCl5 is 208.2. So we will multiply the lower number of moles by our total mass. .316mol X 208.2 g/mol = 65.8g <------ answer.
How does a balanced chemical equation show that mass is never lost or gained in a chemical reaction?
Because the Balanced equation can correctly add the reactants and it will equal the sum of the products.If a chemical equation is balanced correctly, there will be the same number of each element on both sides. Since each element has a given and known mass, the total mass on each side of the balanced equation must be equal.
What is a chemical equation in which both reactant and product have an equal number of atoms of a given element?
A chemical equation where both the reactant and product have an equal number of atoms of a given element is called a balanced chemical equation. This means that the law of conservation of mass is satisfied, and the total number of each type of atom is the same on both sides of the equation.
What is the general formula of a chemical equation?
Generally it is REACTANTS ===> Products Symbollically it can be written as A + B = C + D Where 'A' & 'B' are the reactants and 'C' and 'D' are the products, NB All Chemical reactions obey the Law of CONSERVATION of MASS. So the total of the masses on both sides of the equation MUST be equal . This leads to all chemlcal reaction equations MUST be balanced , because each symbol no only represents an element but also represents a mass. ; Different elements have different masses. But overall the tota, ON BOTH sidesL must BE Equal. e.g. 20 g of A + 15 g of B = 30g of 'C' + 5g of 'D'. 20 + 15 = 30 + 5 = 35 Similarly 2NaOH + H2SO4 = Na2SO4 + 2H2O Notice there are 2 sodiums(Na) on both sides (2 x 23 = 46) 6 oxygens on both sides (6 x 16 = 96) 4 hydrogens on both sides ( 4 x 1 = 4) 1 sulphur on both ( 32 x 1 = 32). Since each element has its own atomic mass , the numbers of each element are the same on both sides, then it follows that the total masses are the samer on both sides. Hence the Law of CONSERVATION of MASS is obeyed. S
How does a balanced chemical equation shows that mass is conserved?
A balanced chemical equation shows that mass is conserved because the total mass of the reactants before a chemical reaction must equal the total mass of the products after the reaction. This is achieved by ensuring that the number of atoms of each element is the same on both sides of the equation. Therefore, what is consumed on the reactant side is equal to what is produced on the product side, preserving total mass.

Which step of the Krebs cycle requires both nad and ADP as reactants?
The step of the Krebs cycle that requires both NAD and ADP as reactants is the conversion of isocitrate to alpha-ketoglutarate, catalyzed by isocitrate dehydrogenase. NADH and ATP are produced in this step.

What is the reactant of sodium and water?
Both are reactants in this reaction.
In making CO2 what is the limiting reaction?
It depends of how much of your reactants you have. start off with just one of the reactants and use dimentional analysis, which is difficult to do on a computer but i bet you should know how to do it. you just start off with one of the given amounts and use the molar ratio in the balanced chemical equation and judging on both of your reactants choose the one that is completely used up in the RxN.
What is doubling the mass of both masses would result in a change of force between the masses of?
IF you're talking about the mutual forces of gravitational attraction between thetwo masses, then doubling both of their masses increasesthe magnitude of theforces by a factor of 4 ... provided the distance between the masses doesn'tchange.
How can two objectes with different masses execute the same force?
If the weight of both masses are the same.
Gravitational force between two objects depend on the masses and what factor between them?
both masses, and the square of the distance between both centers of mass

What represents the correct way to write a chemical equation reactants--products products equals reactants reactants equals sum sum--- reactants?
The correct way to write a chemical equation is: Reactants -> Products. This means that the reactants on the left side of the arrow are converted into products on the right side. The double arrow symbol <=> can be used to indicate that the reaction can proceed in both directions to reach an equilibrium.
What is to the left in a chemical equation?
By convention, the reactants are to the left and the products are to the right. For equilibrium equations, since the reaction goes both ways it's more or less arbitrary.
Where do the reactants from respiration come from?
from the blood stream, both carbohydrates and oxygen.
