Answer:
The side with lots of H+ and low pH
Explanation:
Because one of the feature of an acid is the ability to dissociate to H+.
And it has lower pH because the concentration of H+ is more than OH-
Answer:
If the numbers of each type of atom are different on the two sides of a chemical equationExplanation:
Answer:
Antimony - metalloid
Tungsten- Transition metal
Argon - Noble gas
Iron - Transition metal
Bromine- Halogen
Cesium- Alkali metal
Cerium- lanthanide
Uranium - Actinide
Calcium- Alkaline earth metal
Lithium - Alkaline metal
Explanation:
Lithium is an alkaline metal because it belongs to group 1 of the periodic table. This is the general name for the group.
Calcium is an alkaline earth metal as it belongs to group 2 of the periodic table. This is the general name of the group.
Uranium is an actinide as it belongs to the second series of the f block
Cerium is the second element in the lanthanide series after lanthanum
Cesium belongs to group 1 and hence is an alkaline metal.
Bromine is a halogen as it belongs to group 7 of the periodic table
Iron is a transition metal as it belongs to the first series of transition metals
Argon is s noble gas as it belongs to group 18
Tungsten is s transition element and it belongs to the third series
Antimony is a metalloid
Answer: 15.7 liters
Explanation: reaction is 2H2 + O2. -> 2H2O
Because all substance still are gases, volumes in
STP conditions are proportional to amount of moles.
Amount of water is same as Hydrogen. Also volume is same.
Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
