Answer:
1. Decomposition of stone due to acid rain.
3. The pink color of a rose.
Explanation:
Chemical changes always end up with new products in an equation, or it has always something to do with chemicals. Physical changes on the other hand, do not result in new products and it just changes the physical properties and physical state of matter of the object.
That would be cause part of the sodium is pure and that means it still kind of has it properties when it was an element and that its i think.
The first object because the more mass the hard it is to hold and the density it has which is the mass, the reason why one sunk and the other didn’t is because the higher the mass the faster the object would sink
Answer:
=> 0.10 moles
Explanation:
The question is asking us to find the moles of NaCl cid formed.
We have been provided with;
0.10 L of 1.0 M NaOH.
We know that mole ratio of the reaction is 1:1 and also the molarity of a solution is contained in 1 L or 1000 mL or 1000 cm³.
This means that;
1.0 M is contained in 1.0 L.
X mol is contained in 0.10 L
= 0.10 moles of NaCl formed
