How is the reaction of displacement shown?
In a displacement reaction, a more reactive element displaces a less reactive element from a compound. This is shown by the change in color, formation of a precipitate, or evolution of gas in the reaction mixture. The displacement reaction follows the pattern: A + BC -> AC + B.
What does a chemical reaction show?
It shows the preservation of mass and of matter.
What is a chemistry integer?
In chemistry, an integer is a whole number that represents the stoichiometry or ratio of atoms or molecules in a chemical reaction or compound. It helps in determining the exact amounts of reactants needed and products formed in a reaction.
The proportions of the reactants and products involved in a chemical reaction are shown by the what in the balanced equation describing the reaction?
The coefficients in a balanced chemical equation show the proportions of the reactants and products involved in a chemical reaction. Each coefficient represents the number of moles of each substance in the reaction.
Is the products of the reaction shown in a balanced chemical equation?
. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
What kind of chemical relation is shown 2H2 plus O2 equals 2H2O?
A balanced chemical reaction.
What law is shown by a balanced equation?
The law of conservation of mass is shown by a balanced chemical equation, which states that matter cannot be created or destroyed in a chemical reaction. This means that the number of atoms of each element must be the same on both sides of the equation.
What type of reaction is shown below Sr(s) plus Cl2(l) SrCl2(s)?
This is a single replacement reaction where strontium (Sr) replaces chlorine (Cl) in the compound, forming strontium chloride (SrCl2).
How many grams of oxygen are produced when 11.5 grams NO2 is formed?
For every 1 mole of NO2 produced, 1 mole of oxygen is also produced. The molar mass of NO2 is 46.01 g/mol. 11.5 g of NO2 is equivalent to 0.25 moles. Therefore, 0.25 moles of oxygen (O2) will be produced, which is equal to 5.65 grams.
What symbolic representation of a chemical reaction?
A chemical reaction can be symbolically represented using a chemical equation, where reactants are shown on the left side and products are shown on the right side. The equation includes chemical formulas of the substances involved and indicates the balance of atoms before and after the reaction.
How is the law of conservation of mass shown by a balanced equation?
In stoichiometry, the equation is balanced by using molar ratios. Because each item on either side of the equation has a specific molar mass, it can be demonstrated that all mass is conserved through the chemical reaction.
What is the theoretical number of moles of hydrogen gas should be produced when 0.068 mol of sodium metal reacts?
The balanced chemical equation for the reaction of sodium metal with water is: 2Na + 2H2O -> 2NaOH + H2 Therefore, 2 moles of sodium react with 2 moles of water to produce 1 mole of hydrogen gas. Since you have 0.068 mol of sodium, the theoretical number of moles of hydrogen gas produced would be 0.034 mol.
How is the law of conversion of mass shown by a balanced chemical equation?
The law of conservation of mass is shown by a balanced chemical equation because the total mass of the reactants must equal the total mass of the products. This is achieved by ensuring that the number of atoms of each element is the same on both sides of the equation. Therefore, mass is conserved in a chemical reaction.

How many milliliters of a 2.00 M solution of nitric acid are needed to completely react with 15.0 g of sodium hydroxide according to the chemical reaction shown below?
The balanced chemical equation for the reaction is 2HNO3(aq) + 2NaOH(aq) → 2NaNO3(aq) + 2H2O(l). Using the given information, we first find the moles of sodium hydroxide by dividing the mass by the molar mass. Then, we use the mole ratio from the balanced equation to find the moles of nitric acid needed. Finally, we use the definition of molarity to find the volume of the solution required.
