The elements that fill the d orbitals on the periodic table are called transition metals.
Answer:
the answer is nitrogen
Explanation:
u can right this for explain your answer-
( nitrogen is unreactive
nitrogen doesn't support burning )
orrrrr
(contains no oxygen
all the other jars contain oxygen)
Answer:- 29.6 moles of carbon.
Solution:- We have been given with 3.7 moles of 
and asked to calculate the moles of C.
Looking at the formula of the compound, there are 8 carbons in it means 1 mol of he compound has 8 moles of C. So, if we multiply the given moles of the compound by 8 then we get the moles of C.
= 29.6 mol C
Hence. there are 29.6 moles of C in 3.7 moles of .
The Bohr Model, which was proposed by Niels Bohr in 1913
Energy is required to change the phase of a substance, such as the energy to break the bonds between molecules in a block of ice so it may melt.
During a phase change energy my be added or subtracted from a system, but the temperature will not change. The temperature will change only when the phase change has completed. No temperature change occurs from heat transfer if ice melts and becomes liquid water (i.e., during a phase change). For example, consider water dripping from icicles melting on a roof warmed by the Sun. Conversely, water freezes in an ice tray cooled by lower-temperature surroundings. Energy is required to melt a solid because the cohesive bonds between the molecules in the solid must be broken apart so that the molecules can move around at comparable kinetic energies; thus, there is no rise in temperature.
