30g of ammonium dichromate and 20 g of magnesium sulfate combined which will be the limiting factor?

Reactants: 30 g (NH4)2Cr2O7, 20 g MgSO4 30 g (NH4)2Cr2O7 / 252.07 g/mol = 0.119 mol 20 g MgSO4 / 120.41 g/mol = 0.166 mol Since they react in a 1:1 ratio to form magnesium dichromate and ammonium sulfate, ammonium dichromate is the limiting reagent (only 0.119 mol of MgSO4 is needed to react with all the (NH4)2Cr2O7).

What is the limiting factor in the reaction of hydrochloric acid and magnesium?
the limiting factor varies between the magnesium and hydrochloric acid as there needs to be enough hydrogen for every magnesium..
What is the limiting reagent if 6 moles of magnesium react with 6 moles of nitrogen to form magnesium nitride.?
This is the amount of magnesium.
What is the limiting reagent when 0.343 g of magnesium chloride is reacted with 10.0 mL of 2.00 M sodium hydroxide?
The limiting reagent is sodium hydroxide.
Why is ammonium nitrate a good fertiliser?
nitrogen is often (though not always) the limiting factor in plant growth, and since both the ammonium (NH3) and the nitrate (NO3) both contain nitrogen (N) and plants can absorb both these molecules, it can inhance plant growth.
A limiting nutrient is an example of a?
For plants, there are three main limiting factors that affect the rate of photosynthesis. >Light and its intensity >Carbon dioxide concentration >Temperature As for nutrients .. Magnesium is up taken by the plants roots through osmosis in the root hairs.. to help in production of chlorophyll.
How 2 moles of Magnesium oxide are formed when 4 moles of Mg reacts with O?
2Mg + O2 -----> 2MgO So two moles of magnesium oxide are formed if x moles of magnesium are allowed to react with only 1 mole of oxygen molecules. The oxygen has become the limiting ingredient.
What is the theory yield of magnesium chloride when 5.6 grams of magnesium is reacted with elemental chlorine there is an excess of elemental chlorine the 5.60g magnesium is the limiting reactant?
magnesium + chlorine --> magnesium chloride Mg (s) + Cl2 (g) --> MgCl2 (s) 5.60 g Mg x 1 mol Mg x 1 mol MgCl2 x 95.21 g MgCl2 = 21.9 g MgCl2 ..................24.31 g Mg. 1 mol Mg........ 1 mol MgCl2
How many moles of magnesium nitrate are produced when magnesium reacts with 8 moles of nitric acid?
Mg2+(s) + 2HNO3(l)= Mg(NO3)2(aq) + H2(g) since the only mole value given is 8 I must assume this is the limiting reactant. Because of the 2:1 ratio of Nitric acid to Magnesium Nitrate, meaning there must be 2 moles Nitric acid for every 1 mole Magnesium Nitrate formed, 4 moles of Magnesium nitrate will be formed.
What restricts the number of individuals in a population is a what factor?
Limiting factor
Why is the term limiting used to describe the limiting reactant?
The term "limiting" is used because the limiting reactant limits the amount of product produced.
How much magnesium sulphide can be made from 1.0gram of magnesium and 1.0gram of sulphur?
The formula of magnesium sulphide is MgS, showing that a formula unit has one atom of each element. The gram atomic mass of magnesium is 24.305 and that of sulphur is 32.06. Therefore, when magnesium and sulphur are present in equal amounts by mass, sulphur is the limiting reactant. 1.0/32.06 or 0.031 moles of sulphur atoms are present. Therefore, the maximum amount of MgS that can result from reaction is 0.031 formula units of MgS. The gram formula mass of MgS is 56.365, so that 0.031 formula units of MgS will have a mass of 1.7 grams, to the justified number of significant digits.
In the reaction MgCl2 plus 2KOH gives magnesium hydroxide plus 2KCl if 3 moles of MgCl2 are added to 4 moles KOH what determines how much magnesium hydroxide is made?
MgCl2(aq) + 2KOH(aq) --> Mg(OH)2(s) + 2KCl(aq)It is the molar ratio in the equation. Every mole of magnesium chloride requires 2 moles of potassium hydroxide. Thus 3 moles would need 6 moles of alkali for complete reaction. We don't have that much, so potassium hydroxide is the limiting reactant and we can only use 2 moles of the magnesium chloride and produce 2 moles of magnesium hydroxide.
