Answer:535.5g
Explanation:
1) find the volume of the object
=L*W*H
=1.8*3.5*10.0
=63cm^3
2) the original formula is solving for the dencity which we have so...
D=M/V
M=D*V
M=8.5(63)
M=535.5g
Answer:
the reaction rate of 1,000 k is 17.28 m/s
Explanation:
The computation of the reaction rate in case when NO is increased to 0.12 M is shown below:
According to the question, data provided is as follows
NO = 0.12M

Based on the above information
Reaction rate is

= 17.28 M/s
Hence, the reaction rate of 1,000 k is 17.28 m/s and the same is to be considered
Answer is: another name for groups of elements is family.
There are 18 numbered groups in the periodic table.
The elements in a group have similar physical or chemical characteristics and some groups have a specific name, for example group 17 (the halogens).
Elements in the group have the same number of valence electrons, for example, chemical elements in group 15 of the periodic table have neutral atom with a valence electron configuration of ns²np³.
