Subtract the mass number which is 157 from your atomic number which is 60. 157-60=97 neutrons.
Answer:
it's describes the velocity. since a direction was specifically given, that means it is displacement, and displacement is to velocity while distance is to speed
The graphs can be described as
So in case of inverse relationship we will obtain a curve not straight line
Easy the partial pressure is the 0.9883 as the linguistic compound of the average element of the shell is the same as the boron
Answer : The net ionic equation will be,

Explanation :
In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation,
is the spectator ion.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be,
