Answer:
O=O bond
Explanation:-
Note it down that the bond having highest Hydrogen enthalpy has strongest bond.
Now
- O=O(495KJ/mol)
- O-O(146KJ/mol)
- O-H(467KJ/mol)
- H-H(432KJ/mol)
Hence
Answer:
hi there !!
B) Water evaporates into steam.
this is correct because only physical state changes, steam can be cooled down to get water again.
Answer:
Acid/String Electrolyte
Explanation:
Litmus paper turning red means it is an acidic solution. A pH of more than 7 is Base while pH of less than 7 is an acid. Since the pH is 2, less than 7, it s is an acid. Since it has a high electrical conductivity, it must be a strong Electrolyte.
Answer:
I think that gravity can be considered a force.
Explanation:
As the object falls, it moves faster and faster. Gravity is considered a universal force because it acts between any two masses anywhere in the universe. For example, there is a gravitational pull between the Sun and the Moon. Even small masses attract one another.
Hope this helped! :)
