If the number of atoms of each element in the products equals the number of atoms of each element in the reactants the equation is?
In this case, the equation is balanced.
How can you balance Sodium carbonate and silicon dioxide to react form sodium silicate and carbon dioxide?
To balance the reaction between sodium carbonate and silicon dioxide to form sodium silicate and carbon dioxide, you need to ensure the number of atoms of each element is the same on both sides of the chemical equation. This can be done by adjusting the coefficients in front of each compound. The balanced equation for this reaction is: Na2CO3 + SiO2 → Na2SiO3 + CO2
How many grams of NaOH are formed from reacting 120g sodium carbonate with excess calcium hydroxide?
Write out the equation, and remember to balance each side.Na2CO3 + Ca(OH)2 --> 2NaOH + CaCO3Molecular WeightsNa2CO3: 106 grams/moleNaOH: 40 grams/moleAlways convert your reagents into moles.(120g Na2CO3) x (1 mole Na2CO3/106 grams Na2CO3) = 1.132 molesAccording to the balanced equation, 1 molecule of Na2CO3 generates 2 molecules of NaOH.(1.132 moles Na2CO3) x (2 moles NaOH/1 mole Na2CO3) = 2.264 moles NaOHNow determine the number of grams from 2.264 moles of NaOH.(2.264 moles NaOH) x (40 grams/ 1 mole NaOH) = 90.57 grams NaOH formed.To prevent rounding off too many times, carry out the dimensional analysis in one step:(120g Na2CO3) x (1 mole Na2CO3/106 grams Na2CO3) x(2 moles NaOH/1 mole Na2CO3) x (40 grams/ 1 mole NaOH) = 90.57 grams NaOH
Is cucl2 h2s cus 2hci a balanced equation?
CuCl2 + H2S --> CuS + 2HCl Yes, this is the balanced equation here.
How can I tell if a chemical reaction is balanced or not balanced?
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
How do you balance the equation for Naco3 HCL?
The balanced equation for NaCO3 + HCl is: Na2CO3 + 2HCl -> 2NaCl + H2O + CO2. Balancing the equation involves making sure there are the same number of each type of atom on both the reactant and product sides.
How do you determine whether the equation is balanced?
To determine if an equation is balanced, compare the number of each type of atom on the reactant side to the product side. Make sure there is an equal number of each type of atom on both sides of the equation. If the number of atoms is balanced, the equation is balanced.
How do you balance hydrochloric acid and and sodium carbonate?
To balance the chemical equation between hydrochloric acid (HCl) and sodium carbonate (Na2CO3), you first write the unbalanced equation: HCl + Na2CO3 -> NaCl + H2O + CO2. Then you balance the equation by ensuring the same number of each type of atom on both sides of the equation, which in this case would be: 2HCl + Na2CO3 -> 2NaCl + H2O + CO2.
How do you balance sodium hydroxide carbonic acid?
There are to possible reactions depending on the relative amounts of each substance. If there is an abundance of sodium hydroxide the balanced equation will be: 2NaOH + H2CO3 --> 2H2O + Na2CO3 If there is more carbonic acid: NaOH + H2CO3 --> H2O + NaHCO3
What determines if a chemical equation is balanced?
If the number of atoms of each element is the same on both sides of the equation, then it is balanced.
An equation is balanced when .?
the number and type of atoms of reactant and product are the same
If the number of atoms of each element in the products equals the number of atoms of each element in the reactants the equation is?
In this case, the equation is balanced.
How do you tell if a equation is balanced?
An equation is balanced when the number of atoms of each element is equal on both sides of the equation. This means that the total mass and charge is conserved. You can check if an equation is balanced by counting the number of atoms of each element on both sides of the equation and adjusting coefficients as needed.
Is this equation balanced CaO HCL CaCl2 H2o Yes thank you What I need to know is the number of atoms in the reactants of the chemical equation?
The equation given is not balanced. To determine the number of atoms in the reactants, you need to balance the equation first. Once balanced, you can count the total number of atoms on each side of the equation.
How many grams of HCL needed to react with 4000 g of Na2co3?
The balanced chemical equation for this reaction is 2 HCl + Na2CO3 -> 2 NaCl + H2O + CO2. From the equation, 1 mole of Na2CO3 reacts with 2 moles of HCl. Calculate the number of moles of Na2CO3 in 4000g, then use the mole ratio to find the moles of HCl needed. Finally, convert moles of HCl to grams.
