How do you write the balanced equation between an acid and a base?
An example is:2 KOH + H2SO4 = K2SO4 + 2 H2O
What makes up a mloecule of water?
two hydrogen and oxygen H2O (small 2)
How calcium carbonate is formed write chemical equation?
Ca(OH)2 + CO2 = CaCO3 + H2O
When organic compounds are burned they react with oxygen to form CO2 and H2O. Write balanced equations for C2H6O?
The chemical equation is:C2H5OH + O2 = 2 CO2 + 3 H2O
What is the composition of oxygen in the present atmosphere?
H2O (small 2!) - 2 hydrogen atoms bonded to one oxygen atom.
How do you write H2O in HTML code?
To write the elemental definition of water (H20) in HTML, use the <sub></sub> element to surround the 2. SUB designates a particular portion of text as subscript. So... <p>H<sub>2</sub>O</p> Will give results similar to: H2O
What is the balanced equation of calcium oxide reacts with water to form calcium hydroxide?
how do you write a balanced chemical formula for this question CaO + H2O ---> Ca(OH)2
Are you suppossed to write in the dude book?
yes ur supposed 2 do everything it tells u to do to it
Why is water supposed to be h8O?
its H2O and its because water is made up of 2 Hydrogen atoms and 1 Oxygen atom. H= Hydrogen O= Oxygen
How would you write this balanced C2H6 plus O2 ---- CO2 plus H2O?
C2H6 + O2 = CO2 + H2O There are two carbons in the reactant, so there are two carbon in 'CO2', by writing '2CO2' . Hence C2H6 + O2 = 2CO2 + H2O Similarly, there are six hydrogen in the reactant, so there are six hundreds in H2O , by writing ' 3H2O . Hence C2H6 + O2 = 2CO2 + 3H2O To balance the oxygens, we now think ' backwards'. We note in the products there are 2 x 2 = 4 oxygen in CO2. and 3 x 1 = 3 in H2O. So we need 4 + 3 = 7 oxygens in the reactants. We already have '2' oxygen in the reactants as 'O2' . To make this up to '7' , we write ' 3 1/2' as the molar ratio/. ( 2 x 3 1/2 = 7) Hence C2H6 + ( 3 1/2)O2 = 2CO2 + 3H2O Chemists do NOT like fractions in the molar ratios. So to remove the '3 1/2' we multiply the whole reaction eq'n by '2'. Hence 2C2H6 + 7O2 = 4CO2 + 6H2O is the balanced reaction eq'n. NB Note the number of each type of atom are equal on both sides. 4 carbons 12 hydrogens 14 oxygens. NNB When doing these combustion eq'ns for alkanes, alkenes, alkynes, etc., Think to forward balance the carbons and hydrogens, then 'Back' think of the number of oxygens.
How do you write chemical formula of water?
2 hydrogen molecules 1 oxygen molecule H2O
