Answer what are you asking
Explanation:
Nb, the transition metal(d) subshell will always be n-1, meaning the 3d subshell will be in row(period) 4. So if it’s 4d then it is row(period) 5, and if it has 3 valence electrons then the element is located in column V, or the third column in the transition metal section.
Answer:
Carbon dioxide is used up, and oxygen is produced.
Explanation:
For photosynthesis to occur the plant need carbon dioxide water and sunlight to convert it into glucose for it to eat and oxygen is a byproduct of the chemical reaction.
Answer:
Al
Explanation:
Aluminum (Al) is in the same group as Boron (B) so it should have three electrons or dots around it.
Hope that helps.
The gas will obey Boyles Law:
P1 V1 = P2 V2 where P1 and V1 are the original pressure and volume and P2 and V2 are the new values.
If V2 = 2V1 (given) then:
P1 V1 = P2 *2 V1
P2 = P1 V1 / 2V1
P2 = P1 / 2
In other words the pressure is halved. (answer).
