What is the equation between ammonium sulphate and magnesium oxide?
It gives: magnesium sulfate + Ammonia + Water
What flammable liquid gives off vapors at below room temperature?
Propane and butane
What is the chemical equation for the neutralization reaction of NH3 titrated with HCl?
This reaction gives ammonium chloride as the product.
What information does the coefficients provide in a balanced equation?
The coefficient in a balanced equation tells you the ratio of moles/molecules/etc of one reactant to the other reactants, and to the products. It gives you the stoichiometry of the reactions.
What does the arrow mean in a equation?
It sort of means 'equals', but more correctly means 'gives' or 'produces'
Is a liquid endothermic or exothemic?
A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.
What is the written word equation for thte process that release carbon dioxde?
Hydrocarbon when burnt in the presence of oxygen gives carbon dioxide + water. Or CnHn gives CO2+ H2O. Incomplete combustion gives carbon monoxide and water.
What are some examples of physical and chemical changes with equation?
physical change is a reversible temporary process like ice turning into water nd vice verse chemical change is irreversible permanent process like rusting of iron ,burning of L.P.G, heating of sugar 1.ice(solid) on heating water (liquid) (physical) 2.4Fe +3O2 gives 2Fe2O3 Fe2O3 + H2O gives Fe2O3.H2O (RUST) (chemical change)
How can you tell a linear function from an equation?
An equation is a statement that two things are equal. A function is a rule or process that gives you a value if you give it something in its domain (the set of things on which it is defined) as an argument. Functions on numbers that are defined by a rule can usually be expressed by an equation. A linear function is one that can be defined by a linear equation.
What equation do you use when it gives you 2 temperatures and 1 ml and you have to find volume?
An equation that gives the coefficient of thermal expansion of whatever the material is.
What is the difference between integration and derivation?
Integration results in an equation which gives the area under the original equation between the bounds. Derivation results in an equation which gives the slope of the original line at any point.
What is wrong with the equation CaO O gives CaO?
Ca + O2 gives 2CaO
What equation gives you 84?
12*7=84
What do you call the numerical value that gives a true statement when it is substituted for the variable in the equation?
You call that a "solution" of the equation.
What is the answer to x-y equals 2 2x plus 3y equals 4 using multipication and addition method?
x - y = 2 : Equation 1 2x + 3y = 4 : Equation 2 Multiplying Equation 1 by 3 gives 3x - 3y = 6 : Equation 3 Adding Equation 2 to Equation 3 gives 5x = 10 Dividing both sides by 5 gives x = 5 Substituting x=5 into Equation 1 gives 5 - y = 2 Therefore y = 3. Our final answer is therefore x=5 and y=3
Does condensation lose or gain energy?
Condensation gives off energy. Matter is moving from the higher energy vapor state to a lower energy liquid state. This is an exothermic process.
