The equation is not balanced. If we combine hydrochloric acid (HCl) and calcium (Ca), it will look like this:
2HCl + Ca → CaCl2 + H2↑The H2 here is hydrogen gas.

What is the chemical equation potassium and lead nitrate react to form potassium lead nitrate and lead?
through a double displacement reaction. 2Ca + Pb(NO3)4 = Pb + 2Ca(NO3)2
What causes the chemical reaction of calcium carbonate in an egg and acetic acid?
The reaction is:CaCO3 + 2 CH3COOH = (CH3COO)2Ca + H2O + CO2
For the reaction calculate how many moles of the product form when 0.046mol of O2 completely reacts. Assume that there is more than enough of the other reactant. 2Ca(s) O2(g)2CaO(s)?
0,092 moles CaO
What is the balanced equation for fluorine and calcium chloride?
F2 + 2CaCl --> 2FCl + 2Ca submitted by Ethan + JD FTW
What is 3ac plus 2ca?
3ac + 2ca = 3ac + 2ac = (3 + 2)(ac) = 5ac
Calcium plus Hydrochloric acid?
2Ca+4HCl->2CaCl2+2H2 or more simply... Ca + HCl -> CaCl2 + H2
How do you balence Ca plus O2 plus C equals CaCO3?
2Ca + 3O2 + 2C -> 2CaCO3
Can anyone help me with maths 6ab-5bc plus 2ca plus ab plus 6bc-10ac this is a sample of what I have to do. Can you please show working so I get an idea. Thanks?
This is an algebra question. All you can do is sum similar terms. You get 6ab-5bc+2ac (same as 2ca) +ab+6bc-10ac = 7ab-8ac+bc
Which of the following are elements in this equation 2Ca s plus O2g 2CaO s?
Calcium (Ca) is element. O2 and CaO are molecules.
What is the equation of oxidation of calcium?
2Ca + O2 = 2 CaO
What is the symbol equation for calcium oxide?
2Ca + O2 ------> 2CaO
What is the chemical formula for calcium ethanoate?
Formula: (CH3COO)2Ca
A plus b plus c whole square?
(a+b+c) 2=a2+ab+ac+ba+b2+bc+ca+cb+c2a2+b2+c2+2ab+2bc+2ca [ ANSWER!]
What happens when metals react with air water and acids?
Do you mean seperately?If yes, then:When they react with air, it is combustion: 2Ca + O2 --> 2CaOWith water, they simply come to be hydroxides: Na + H2O --> NaOH + H2When they react with acids then a salt and hydrogen gas is formed: Zn +2HCl --> ZnCl2 + H2
If a2 plus b2 plus c2 - ab - bc - ca equals 0 then prove a equals b equals c?
a2 + b2 + c2 - ab - bc - ca = 0 => 2a2 + 2b2 + 2c2 - 2ab - 2bc - 2ca = 0 Rearranging, a2 - 2ab + b2 + b2 - 2bc + c2 + c2 - 2ca + a2 = 0 => (a2 - 2ab + b2) + (b2 - 2bc + c2) + (c2 - 2ca + a2) = 0 or (a - b)2 + (b - c)2 + (c - a)2 = 0 so a - b = 0, b - c = 0 and c - a = 0 (since each square is >=0) that is, a = b = c
