Bombardment of cobalt-59 with a neutron produces a manganese-56 atom and another particle. What is this particle?A. an alpha par
ticleB. a beta particle (electron)C. a positronD. a gamma rayE. a neutron
1 answer:
Answer:A
Explanation:
A nuclear reaction is balanced by ensuring that the Masses and charges of te reactants and products are exactly balanced on the left and right hand side of the reaction equation. If there are 60 mass units on the LHS and manganese has only 56 mass units then four mass units are left. If there is no charge on a neutron and there is a charge of 27 on the cobalt, then two charges are left. Four mass units and a charge of +2 corresponds to a helium which is actually an alpha particle.

Answer: Three things are missing:
i) Graph title.
ii) Label for the vertical axis.
iii) The scale and the units for the horizontal axis.
Justification:
1) Find the graph in the image attached.
2) What does the graph represent? You cannot tell because it does not show the tittle.
Since you are told in the statement that it is a temperature and volume graph, the appropiate title would be:
Temperature vs. Volume.
3) The vertical axis also must be properly labeled, including the units.
A good label for the vertical axis of this graph might be: Volume (cm³). It migh also be liters, gallons, or other volume unit.
4) Although the horizontal axis is labeled, it does not indicate the units and the scale. So, you know neither if the temperature shown is celsius, (°C), farenheti (°F), kelvin (K), or rankine (R) (those are the four major scales of temperature), nor how much each division represent (1, 5, 10, 10, 50, 100?)
