The FORMULA for the limiting reagent is .
4.27 grams of reactant remains after the reaction is complete.
<h3>What is a limiting reagent?</h3>The limiting reagent is the reactant that is completely used up in a reaction and thus determines when the reaction stops.
Given data:
Mass of sulfuric acid = 41.0 grams
Molar mass of sulfuric acid = 98.08 g/mol
Mass of zinc hydroxide = 36.5 grams
Molar mass of zinc hydroxide = 99.424 g/mol
Step 1:moles sulfuric acid = mass sulfuric acid / molar mass sulfuric acid
moles sulfuric acid = 41.0 grams / 98.08 g/mol
moles sulfuric acid = 0.41 moles
Step 2: moles of zinc hydroxide
moles zinc hydroxide = 36.5 grams / 99.424 g/mol
moles zinc hydroxide =0.367 moles
Step 3: Calculate limiting reactant
zinc hydroxide is the limiting reactant. It will completely be consumed.
There will remain 0.41 moles - 0.367 moles = 0.043 moles
This is 0.043 moles x 99.424 g/mol
= 4.27 grams

Newton's first law of motion predicts the behavior of objects where all existing forces are balanced. Objects at equilibrium will not accelerate. Also, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.
Newton's second law of motion: behavior of objects for and all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
