The requirement for a balanced equation is that the numbers of each kind of atoms in the reactants must match the number of each kind of atoms in the products. The number of atoms in each molecule in the equation is the product of the coefficient and the subscript affixed after each element symbol in the formula to which the coefficient applies. For example, 2 Na + Cl2 = 2 NaCl. The coefficients on the left side total 3 but those on the right side total only 2. However, the number of atoms of each of sodium and chlorine total 2 on each side.
What else can I help you with?
Write the balanced equation for Aluminum hydroxide and sodium nitrate react to produce aluminum nitrate and sodium hydroxide thank you and please explain?
Al(OH)3 + 3NaNO3 >> Al(NO3)3 + 3NaOH This is a double displacement reaction between metals ( Aluminum is a transition metal, but has only a 3+ oxidation state. ) and polyatomic ions of negative charge. Both are 1- in charge. Sodium is 1+ in charge. This is why the atoms are arranged as they are with the polyatomic ions enclosed in parentheses where needed. Remember, botgh sides of the equation musr contain the same number of atoms. Count carefully and you will see this is the case.
Why does a chemical equation have to be balanced?
Balancing Chemical Equations is absolutely essential if you want to determine quantities of reactants or products. An unbalanced chemical equation gives only the identify of the beginning reactants and the final products using the appropriate formulas as well as the conditions of temperature, physical state, and pressure conditions under which the reaction is to operate under. However an unbalanced equation can say nothing about the quantities involved until the equation has been balanced. A balanced equation assures that the conservation law of matter is obeyed. The total mass of reactants must equal the total mass of products. A balanced equation tells you the proportional quantities of each substance involved.
Why is a chemical reaction rate doubled when the concentration of one reactant is doubled explain this in terms of collision theory?
Pretty simple, really. For any one "A" molecule, if there are twice as many of the other "B" molecule present then the odds of it colliding with one of them are twice as high. The same equations for effective collisions hold, so doubling the concentration doubles the reaction rate.
What happens in a reaction between calcium carbonate and acetic acid?
Answer2CH3COOH(aq)+1Ca(OH)2(s)---2H2O(l)+1Ca(CH3COO)2(aq)Can also be written as2 HC2H302 (aq) + 1 Ca(OH)2 (aq) --> 2 H20 (l) + Ca(C2H302)2 (s)I had a question in my chemistry class that was stated: "Write a balanced chemical reaction from the following word equation: Acetic acid is neutralized with aqueous calcium hydroxide."Writing acetic acid in the second form shown makes it easier to see what salt will be formed after the neutralization.
What do red boxes mean in a chemical equation?
There is no specific meaning for this. It would normally be used to draw attention to particular parts of the system. The author should explain what it's being used for. One example might be 'Is the substance in the red box an oxidising agent, reducing agent or neither?'
Briefly explain what a balanced equation describes.?
Yes
Explain how the balancing of chemical equation shows that mass is conserved?
Balancing a chemical equation ensures that the number of atoms of each element on the reactant side is equal to the number on the product side. This conservation of atoms implies the conservation of mass. When the equation is balanced, the total mass of the reactants is equal to the total mass of the products, demonstrating the law of conservation of mass.
Explain the difference between a constant and a coefficient?
A constant is a fixed value that does not change in an equation, while a coefficient is a number that multiplies a variable. Constants remain the same throughout a mathematical expression, whereas coefficients can vary based on the context of the equation.
Explain what a coefficient in a balanced chemical equation represents?
The coefficients in a chemical equation represent the amount of moles of each substance involved in the reaction. On a smaller level, it also represents the amount of particles that have to collide or are produced in the reaction. Consider the following example: CH4(g) + 2O2(g) (arrow) 2H2O(l) + CO2(g) The coefficent behind oxygen in the reactants means that 2 molecules of oxygen have to collide with 1 molecules of methane to react. The coefficients in the products mean that this reaction produces 2 molecules of water and 1 molecule of carbon dioxide.
Explain how to solve for the variable in a multiplication equation such as 2.3a equals 4.6?
2.3a = 4.6 In order to leave the variable alone (without the coefficient), divide by 2.3 to both sidesa = 2
Explain how a balanced chemical equation show that mass is conserved?
A balanced chemical equation demonstrates the law of conservation of mass because the total mass of the reactants equals the total mass of the products. This means that no atoms are created or destroyed during a chemical reaction; they are simply rearranged to form new substances.
Explain what is meant by a chemical equation being balanced?
A balanced chemical equation has the same number of each type of atom on both the reactant and product sides. This means that the total mass and charge are conserved during a chemical reaction. Balancing the equation involves adjusting the coefficients of the reactants and products to achieve this equality.
Is it possible for a coefficient of variation to be negative Explain.?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
List a balanced chemical equation for a biochemcial reaction and explain how it is used in your example above?
Glucose + Oxygen -> Carbon dioxide + Water This is the balanced chemical equation for the cellular respiration process in living organisms, where glucose and oxygen react to produce carbon dioxide and water, releasing energy that is vital for cellular processes.
6CO2 plus 6H20 C6H1206 plus O2 explain why this equestion is not correct throungh a correct balanced?
The equation is not correct because there are not the same number of each element on each side of the equation.6CO2 + 6H2O ==> C6H12O6 + 6O2
As the equation is written which element is not in balance Explain?
An equation written may or may not be balanced. It is balanced if the number of elements on both sides of the arrow, that is before and after the reaction, is equal. Sometimes the number of elements is not the same on both sides of the arrow, then we need to balance the equation. This is done in accordance to the law of conservation of mass which states that the mass of a substance does not get destroyed or created due to a chemical reaction.
Explain how a balanced equation supports the law of conservation of mass?
A balanced chemical equation shows that the total mass of reactants equals the total mass of products, which supports the law of conservation of mass. This law states that mass cannot be created or destroyed in a chemical reaction, only rearranged. By balancing the equation, we ensure that the number of atoms of each element is the same on both sides, preserving mass.
