What is 2h20?
2H2O is two molecules of H2O. H2O is water -> 2 molecules of water.
2H2 02---2H20 - how many molecules and number of atoms of each element in the equation?
The chemical equation represents the reaction of 2 molecules of dihydrogen (H2) and 1 molecule of dioxygen (O2) to form 2 molecules of water (H2O). In total, this reaction involves 6 atoms of hydrogen (2 in each H2O molecule) and 2 atoms of oxygen (1 in each O2 molecule).
What are the first three steps to the label method?
Select an item to label. Determine the category or label that best describes the item. Attach the label to the item using a label maker or adhesive label.
Which of following is an example of a decomposition reaction?
Decomposition involves a compound molecule , breaking down ( decomposing) into either smaller compounds or elements. If left for a period of time hydrogen peroxide (H2O2) spontaneously decomposes into water and oxygen . 2H2O2 ==> 2H2O + O2 A thermal decompostion reaction is the heating of limestone ( Calcium carbonate). It decomposes to Caclcium oxide and carbon dioxide. Being a thermal decomposition the limestone has to be heated to red (glowing ) heat. CaCO3(s) ==ht==> CaO + CO2
What does a yellow label mean?
In science, a yellow label indicates a medium hazard level.
What is catalase's substrate in this reaction.2h202 and 2h20 plus 02?
Catalase breaks down hydrogen peroxide into water and oxygen. Therefore, its substrate in this reaction is hydrogen peroxide (H2O2).
What is the balanced formula for water?
4h+02 --> 2h20
Does 2h20 plus 2h20 plus 4h2o make a chemical reaction?
It shouldnt.
How can you make a sample of potassium sulphate?
2koh + h2so4 = k2so4 + 2h20
Why does h202 break down into water and oxygen?
Because H2O2 is an unstable molecule - It naturally decays or breaks down into water H20 and the spare oxygen atom combines with another spare to form O2 The furmula is... 2H202 = 2H20 + O2
What is 2h20?
2H2O is two molecules of H2O. H2O is water -> 2 molecules of water.
What is balanced in an acidic solution?
So42- + 4H+ + 2e- goes to SO2(g) + 2H20(I)
What is the balanced in an acidic solution?
So42- + 4H+ + 2e- goes to SO2(g) + 2H20(I)
Balance 2H2S plus SO2-H2o plus 3s?
2h2s + so2 - 2h20 + 3s
What would be the next label after 75oN?
That depends entirely on how the labeled lines are spaced on your particular map or globe. There is no standard. On my mapping software, the next label north of 75° N is 75° 00' 02" N. The next label south of 75° N is 74° 59' 58" N.
Are these balanced co2 plus 4h2 equals ch4 plus 2h20?
Yes. Except that the word is equals, not eqauls.
Which substance is the substrate in the equation 2 H2O2 ------- 2 H2O plus o2?
Hydrogen peroxide (H2O2) is the substrate in the given equation. It is broken down into water (H2O) and oxygen (O2) by the enzyme catalase.
