When writing a chemical equation what must be written first?
First write down what you know. Reactants go on the left, followed by an arrow, with products on the right. Balance the equation.
What is a balanced chemical equation for the decomposition of copper 2 sulfate pentahydrate?
There is a balanced equation to use for decomposition of copper II sulfate pentahydrate. It is the following: CuSO4.5H2O+heat -->CuSO4(anhydrous)+5H2O.
How do you determine the stoichiometry of a reaction?
To determine the stoichiometry of a reaction, you must first write out a balanced equation describing the reaction and then use the coefficients of this statement to represent molar ratios.
Hydrochloric Acid and Magnesium reaction?
First, the balanced equation of the reaction must be considered: Mg + HCl = MgCl2 + H2 Mg + 2HCl = MgCl2 + H2. Notable results in the reaction are the liberation of the H2 which causes bubbles, and the formation of the MgCl2 which causes a foul odor.
What is the term for the maximum amount of product that can be formed from given amounts of reactants?
The maximum amount of product that can be formed is found by first writing out the balanced equation for the reaction. Calculate the number of moles of starting material you have (moles = mass/molar mass) Use the equation to figure out how many moles of product this will produce. Convert this to grams by multiplying by the mole mass (of the new substance this time.)
What is the balanced equation of Caci2 and Na2cO3?
First it's CaCl2, with a lowercase L, not an i. The balanced equation is: Na2CO3(aq) + CaCl2(aq) --> 2NaCl(aq) + CaCO3(s)
What is the balanced equation for ethylcyclohexane in combustion?
This equation, for complete combustion, is C8H16 + 12 O2 => 8 CO2 + 8 H2O. (The first formula in the equation is a molecular formula for ethylcyclohexane.)
The first step in writing a net ionic equation is to write the ions present in what?
It is usually useful to start with a full balanced chemical equation. Then, if dealing with aqueous reactants, see if any solid precipitates are formed. Only the ones in the precipitates should be in your equation. Those still in aqueous solutions are merely spectator ions.
When balancing an equation with carbon dioxide and water what is the first element used to balance this equation?
Whatever you want. You can start with whichever element that isn't balanced

What is the balance equation for NaCl plus BaCl2?
This equation does not balance because 2 chlorine salts do not react with eachother. However, they are both highly soluable in water. By adding H2O, this equation can be balanced.
What do you mean by balanced chemical equation?
A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide. Unbalanced chemical equation: Mg(s) + O2(g) --> MgO(s) Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction. Balanced chemical equation: 2Mg(s) + O2(g) --> 2MgO(s) This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.

What is a balanced chemical reaction?
In a balanced chemical equation there should be the same amount of atoms present in the products as there were in the reactants and only whole molecules can be formed or used (no half molecules). For example... CH4 + 2O2 = Co2 + 2H2O. If you add up the various atoms in the reactants you find 1 x Carbon, 4 x Hydrogen and 4 x Oxygen. The products contain 1 x Carbon, 4 x Hydrogen and 4 x Oxygen. The equation is therefore balanced. You will note also that 2 molecules of O2 were used as reactants in order to produce complete molecules of products.
