Answer:
C.
Explanation:
if I am wrong I am so sorry
Answer:
The unbalanced chemical equation: H₂O₂ → H₂O + O₂.
The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.
Explanation:
- Hydrogen peroxide is decomposed into oxygen and water, which is a slow reaction.
- It is can be catalyzed by using yeast.
The unbalanced chemical equation: H₂O₂ → H₂O + O₂.
The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.
1.0 mol of H₂O₂ is decomposed to 1.0 mol of H₂O and 0.5 mol of O₂.
Answer:D. Ratio of oxygen/nitrogen
Explanation: the ratio will never change no matter the air pressure!
Answer:
Explanation:
The period law state that when elements are listed in order of their atomic numbers, the elements fall into recurring groups, so that there is a recurrence of similar properties at regular intervals.
Na and K in the periodic table fall into the same group, this is because they both have one electrons in their outermost shell.
Na 11 -1s2 2s2 2p6 3s1
K 19 - 1s2 2s2 2p6 3s2 3p6 4s1
They share similar chemical and physical properties. Na and K are very reactive metals, they can loose/donate their outermost electron to non metals in other to attain stable octet state.
The form ionic compound when they react with non metals.
The result is the sound will be louder. This is due to the high amount of energy in the sounds.
