Answer:
Explanation:
- First rearrange the whole equation by keeping t in one side and rest parameters in another side of equation
- Then plug-in all the given values for each parameters and get the solution
or,
Now plug-in all given values:
So,
1500 cm^3 ; 1 mL equals 1 cm^3
Answer:
Explanation:
Elements in the same family belong to the same group.
A group on the periodic table is the vertical arrangement of elements. Elements in the same group have the same amount of valence electrons in their outermost shell. We know that the valency of an element dictates its chemical properties. In group I for example, elements here have just a valence electron, this makes group I elements readily lose their electrons to achieve a noble configuration.
Physical properties to an extent also varies and progresses down the group steadily.
This is why elements in the same family are said to generally have similar properties
Iron (II) oxide is composed of iron with an oxidation number of +2 (shown by the II after iron) and an oxygen that has an oxidation number of -2 (oxygen almost always has an oxidation state of -2). Since the anion and cation both have a charge of +or- 2, they bond with each other with a 1 to 1 ratio and the formula should be FeO
I hope this helps. Let me know if anything is unclear.
