Which one of the following chemical equations is balanced A B C D?
If you are doing PF then it's KOH + H2SO4 � KHSO4 + H2O APEX- 2ca(s)+o2(g) --> 2cao(s)
What type of chemical reaction is CH4 plus 2 O2 -- CO2 plus 2 H2O?
Burning, oxidation.
What type of redox reaction is shown below HgS s plus O2 g Hg l plus SO2 g?
combustion
Could you Balance NH4NO3 - N2 O2 H2O?
2NH4NO3->2N2+O2+4H2O
What is Einstein's Rik equals O2?
relativity intensity kelvin=0xygen2
What is the balanced equation of calcium and oxygen to produce calcium oxide?
2Ca+O2---->2CaO
What is the symbol equation for calcium oxide?
2Ca + O2 ------> 2CaO
What is wrong with the equation CaO O gives CaO?
Ca + O2 gives 2CaO
What is the balanced symbol equation for calcium and oxygen gas with state symbols?
2Ca(s) + O2(g) ----> 2CaO(s)
Calcium metal reacts with oxygen gas to produce solid calcium oxide?
Correct 2 Ca + O2 ------> 2CaO
What is the balanced equation for CaCO3 Cao(s0 plus CO2(g)?
The equation is:CaCO3.......................→CaO + CO2
Which of the following are elements in this equation 2Ca s plus O2g 2CaO s?
Calcium (Ca) is element. O2 and CaO are molecules.
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
Which of the following are elements in this equation 2Ca s plus O2 g 2CaO s?
Calcium, Ca, and oxygen, O2, are elements (first is mono-atomic, the second is diatomic). Calcium oxide, CaO, is a molecule made of two elements.
What would be produced when calcium is heated in air?
Calcium most likely will react with the oxygen in the air. 2Ca(s) + O2(g) -->2CaO(s). It would form solid calcium oxide.
What is the product when calcium is burnt?
Ca + 1/2 O2 => CaO, or quicklime. A more common reaction is the heating of calcium carbonate (limestone or marble) to produce oxygen and quicklime. CaCO3 => CaO +O2
How many moles of the product form when 0.016 mol of O2 completely reacts 2Ca plus O2 ----- 2CaO?
.183mol CaO Ca is your limiting reactant, O2 is your excess reactant. thus 7.34g Ca = .183mol Ca, since the balanced reaction is 2Ca + 1 O2 -> 2 CaO, 1 mol Ca = 1 mol Cao and .183mol CaO is produced.
