The true statement about the balanced equations for nuclear and chemical changes is; both are balanced according to the total mass before and after the change.
A basic law in science is called the law of conservation of mass. Its general statement is that mass can neither be created nor destroyed.
Both in chemical and nuclear changes, mass is involved and in both cases, the law of conservation of mass strictly applies.
This means that for both chemical and nuclear changes; total mass before reaction must be equal to total mass after reaction.
Hence, both reactions are balanced according to the total mass before and after the change.

Answer:
0. 414
Explanation:
Octahedral interstitial lattice sites.
Octahedral interstitial lattice sites are in a plane parallel to the base plane between two compact planes and project to the center of an elementary triangle of the base plane.
The octahedral sites are located halfway between the two planes. They are vertical to the locations of the spheres of a possible plane. There are, therefore, as many octahedral sites as there are atoms in a compact network.
The Octahedral interstitial void ratio range is 0.414 to 0.732. Thus, the minimum cation-to-anion radius ratio for an octahedral interstitial lattice site is 0. 414.
 
        
             
        
        
        
Answer:

Explanation:
We are given the formula: 

This is a molecular formula, because it contains nonmetals. 
1. Name the first element 
The first element is phosphorous (P). Since this is the first element and there is only one, we don't need a prefix. 
2. Second element 
The second element is chlorine (Cl). It has a subscript of 5, so we must add the prefix of <u>hepta</u>-. 
- Phosphorous heptachlorine 
Add the ending of -ide. 
- Phosphorous heptachloride 
The prefix used for the second element is hepta. The compound name is phosphorous heptachloride. 
 
        
             
        
        
        
Answer:
Explanation:
There are 3 types of plastids :-
1) Chloroplasts:- The green plastids which contain chlorophyll pigments for photosynthesis.
2) Chromoplasts:-The coloured plastids for pigment synthesis and storage.
3) Leucoplasts:- The colourless plastids for monoterpene synthesis found in non- photosynthetic parts of the plants.
They are of three types:-  
a) Amyloplasts- stores starch.
b) Proteinoplasts-  stores proteins.
c) Elaioplasts- stores fats and oils.
 
        
             
        
        
        
You may tell when a solution os formed when the item or particle, such as sugar or salt,
dissolves completely in the solvent, such as water. 
Basically, you know when a solution is formed when the material you have placed in the solvent disappears :P
