Answer:
Sediment build up or the movement of water can transfer fossils to different places other than its original place.
Answer:
Natural dyes, although pure from chemicals, are often times more expensive than chemical dyes.
A Bronsted-Lowry base is that which accepts hydrogen proton, H+ from other sources. In this case, the source of the H+ is water. The dissociation of water to its ionic components is,
H2O --> H+ + OH-
Then, the quinoline being the receiver of the dissociated H+ will become,
C9H8N.
Answer:
The complete chemical equation is as;
C + O₂ → CO₂
Explanation:
According to <em>law of mass conservatio</em>n the mass in isolated system can neither be created nor be destroyed. Applying this law to given <u>synthesis reaction</u> means that,
(i) If there is one carbon atom on left hand side of the equation (reactant side) then there must be on e carbon on right hand side (product side) of the equation.
(ii) If there are two oxygen atoms on left hand side of the equation (reactant side) then there must be two oxygen atoms on right hand side (product side) of the equation.
Hence, from equation it is proved that it obeys the said law and the number of atoms on both side are equal i.e.
Reactant Side Product Side
Carbon 1 1
Oxygen 2 2
