What else can I help you with?
What is the equation called when you use greater than less than or equal to?
This is called an inequality.
What can the discriminant tell you about a quadratic equation?
It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.
Sorry What does the algebraic symbol less than greater than mean in an equation?
It means that one factor is greater than (>) or less than (<) some other factor.
Why quadratic equations have two solutions?
If the discriminant of b2-4ac of the quadratic equation is greater the 0 then it will have 2 solutions.
In the quadratic equation ax2 plus bx plus c 0 if b2 - 4ac?
If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.
What is heat included in the equation of an endothermic reaction?
In an endothermic reaction, heat is included as a reactant in the chemical equation to show that the reaction absorbs energy from the surroundings in the form of heat to proceed. The reaction is usually represented as products being greater in energy content than the reactants due to the input of heat.
What is the definition of excess reactant?
An excess reactant is a reactant in a chemical reaction that is present in a quantity greater than required for the reaction to take place. It is not completely consumed during the reaction, leaving some of it leftover.
How can one determine whether a reaction is product-favored or reactant-favored?
One can determine if a reaction is product-favored or reactant-favored by comparing the equilibrium constant, K, to 1. If K is greater than 1, the reaction is product-favored, meaning more products are formed. If K is less than 1, the reaction is reactant-favored, meaning more reactants are present at equilibrium.
When is b greater than 25 in this equation?
That depends on the equation and the question which have not been given.
Can the arrow in chemical equation indicate which compounds have greater mass?
No, the arrow indicates which way the reaction proceeds, often with 2 arrows being used pointing in both directions indicating the reaction is in equilibrium. The compound's mass can be calculated using the molecular mass of the compound from the periodic table.
Looking at a free energy diagram for an equilibrium reaction which of the following scenarios will favor the formation of more reactant?
If the free energy of the reactants is lower than the products in the free energy diagram, then increasing temperature or decreasing pressure will favor the formation of more reactants.
0.400mol of octane is allowed to react with 0.800mol of oxygen Which is the limiting reactant?
To determine the limiting reactant, compare the moles of each reactant to the stoichiometry of the balanced. In this case, the balanced equation is: 2 C8H18 + 25 O2 → 16 CO2 + 18 H2O The moles ratio between octane (C8H18) and oxygen (O2) is 2:25. Calculate the ratio for each reactant: Octane: 0.400 mol * (25 mol O2 / 2 mol C8H18) = 5.00 mol O2 needed Oxygen: 0.800 mol O2. Since the actual moles of oxygen available (0.800 mol) are greater than the moles needed for the reaction with octane (5.00 mol), oxygen is in excess and octane is the limiting reactant.
What is a equation product greater than 1?
2*3 =
What is a excess reagent?
In most reactions there are two types of reactant. One of them is completely consumed and the other is only partially consumed. The reactant that is only partially consumed is the excess reactant.
Why amount of reactant and product do not change in reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
How is the rate of a reaction affected by reactant surface area?
That there is a bigger area of a solid exposed, so there is a greater chance of collisions causing a reaction.
Why does a reaction proceed faster when the reactants have greater surfaces area?
A greater the surface area will cause the reaction will proceed faster because there are more available sites where another reagent or catalyst can "attack" the reactant.
