I believe the correct answer would be that b<span>oiling points and melting points are similar because they both involve the change in a state of a material, but they are different because boiling point involves a change from a liquid to a gas and melting point involves a change from a solid to a liquid. Boiling and melting are phase changes that can happen to a substance however they differ in the process that happens.</span>
The balanced chemical equation for the reaction is as below
KBr (aq) + AgNo3 → KNO3(aq) + AgBr(s)
Explanation
from the equation above the stoichiometric coefficient before KBr is 1, before AgNo3 is 1 , before KNO3 is 1 and before AgBr is also 1. Therefore 1 mole of KBr reacted with 1 mole of AgNO3 to form 1 mole of KNO3 and 1 mole of AgBr.
Answer:
Chemical differentiation
Explanation:
The process by which minerals crystallize out of magma is termed chemical differentiation. Some times, it is referred to as magmatic differentiation.
- Minerals have different properties and at certain environment, it comfortable for the settle out of magma.
- Some minerals can crystallize out at very high temperature.
- Some will form at medium temperature whereas, some are low temperature minerals.
- Based on the properties of the minerals in a melt, a minerals will differentiate at various temperature and pressure regimes.
Answer:
The correct answer is : The particles within all three states of matter are constantly moving.
Explanation:
The particles in the solid, liquid and gaseous states are in motion. In the latter is where they present greater movement and high kinetic energy, then follow the liquid state and finally the solid where the movement is more restricted (in this case, the particles vibrate).
Answer:
60
Explanation:
there's 5 lines, and 800-700=100 each line represents 20 because 20×5=100.
from a to b, there's 3 lines and 3×20=60
