When neutron numbers are changed an ISOTOPE of the element is formed...
the atom becomes an ISOTOPE
If M is the molar concentration of
, n is the number of moles and V is the volume of the solution:
Answer:
C
Explanation:
inertia
inertia is the reluctance of an object at rest or moving to change its state of rest or motion
because the car was moving, the dummy moves with the speed of the car..so when the crash happened the dummy continued to move..it was feeling reluctant to come to rest so was moving
Explanation:
The given balanced reaction equation is as follows.
The given data is as follows.
Mass of solution (that is sample) = 0.5 g
Therefore, calculate the mass of solute as follows.
= 0.178704 g Fe
Now, calculate the percent by mass Fe in the ore as follows.
Percent by mass of Fe in the ore =
=
= 35.7%
Thus, we can conclude that percent by mass of iron in the ore is 35.7%.
