2HNO3 + Ba(OH)2 --> Ba(NO3)2 + 2H2O
Ba(NO3) or barium nitrate is the salt formed
Iron is described as an element because it is a pure substance. A pure substance is where the atoms are similar and cannot be divided into smaller.
Cesium because it is the only one that belongs to the alkali group.
The particles will spread out more, and have more space between them
Answer:
90MJ
Explanation:
Energy= mc^2
Where c= speed of light
m= mass of the object
Mass= m = 1 ug ( then we need to convert from micro gram to micro Joule)= 0.000000001
C= 3× 10^8 m/s
E= = [0.000000001 × (3× 10^8 )^2]
E = [0.000000001 × 89 875 517 873 681]
= 89 875 517.9 joule
Then we can convert to megajoules as
90MJ
