What is the coefficient for H20 when the following equation is balanced K plus H20 plus KOH plus H2?
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
Which set of coefficients balance the following chemical equation H2 02 H20?
The balanced chemical equation is 2H2 + O2 → 2H2O. This means that the coefficients are 2, 1, and 2, respectively.
What is the balance equation for zinc metal plus oxygen gas?
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
What is the balance of K Br2 2KBr?
You need to have values for K, Br2 and 2KBr in order to find out the balance. For example, if you had the values as H2 + O2 = H20 the balanced chemical equation would be 10 H2 = H20.
What is the balanced symbol equation of water?
The balanced symbol equation for water is 2H2 + O2 -> 2H2O.
What is the mistake in H2 plus O2 equals H20?
It is not balanced. There should be a 2 in front of H2 and H2O
Is H2O-H2 plus O2 a balanced chemical equation?
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
What is the coefficient for H20 when the following equation is balanced K plus H20 plus KOH plus H2?
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
Balanced reaction for the decomposition of water?
Water decomposes into Oxygen and Hydrogen gases, each of which is a 2 atom molecule: H20 -> H2 + O2 BUT that's not balanced - there's Oxygen 'appearing' from nowhere on the right side so to balance it (2) H2O -> H2 + O2 But now we have 4 Hydrogens on left and only two on right (2) H2O -> (2)H2 + O2 4 hydrogens and 2 oxygen - > 4 hydrogens and 2 Oxygens Balanced!
Which set of coefficients balance the following chemical equation H2 02 H20?
The balanced chemical equation is 2H2 + O2 → 2H2O. This means that the coefficients are 2, 1, and 2, respectively.
What is the balanced equation for the reaction between 02 and H2?
2h2 + o2 -> 2h2o All letters capitalized!!
What is the balance equation for zinc metal plus oxygen gas?
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
What is the water equation?
In order to have a balanced equation, adding the reactant H2 And O2 (H2+O2) have to come out equal on the product side and the reactant side. This would look like H2+O2 = H2O2
What is the balance of K Br2 2KBr?
You need to have values for K, Br2 and 2KBr in order to find out the balance. For example, if you had the values as H2 + O2 = H20 the balanced chemical equation would be 10 H2 = H20.
How many grams of O2 are required to completely react with 2g of H2?
The balanced chemical equation for the reaction of H2 with O2 to form H2O is: 2H2 + O2 -> 2H2O From the equation, it can be seen that 1 mole of O2 reacts with 2 moles of H2. Since the molar mass of H2 is 2 g/mol and the mass given is 2g, there is 1 mole of H2. Therefore, 1 mole of O2 is needed, which is 32g.
Is o2 a symbol or formula?
o2 is a symbol. A formula is something like O2 + H2 -> H20
What is the coefficient for water in the balanced equation C5H12 o2-Co2 H20?
The coefficient for water in the balanced equation is 6.
