Answer:
1.The reaction that opposes the change
Explanation:
Consider the reaction;
A + B ⇄ C + D
If a constraint such as a change in temperature, pressure or volume is imposed on this chemical system in dynamic equilibrium, the equilibrium position will shift so as to annul the constraint.
This shift in the equilibrium position will favour either the forward or reverse reaction depending on the type of constraint imposed on the system.
Hence, If a chemical system is at equilibrium, any change in the system will always result in an increase of the reaction that opposes the change.
Answer:
Phosphorus can act as an acceptor while galium can act as a donor
Explanation:
In electronics, pentavalent atoms are used as acceptors while trivalent atoms are used donors. Hence the answers provided above.
Answer:
C.
Explanation:
The heat island effect or the the urban heat island effect, is where the temperature of an area is higher than close rural areas. This is because materials suh and concrete and asphalt absorb the sunlight and store it, causing extreme weather.
Explanation:
Radioactive isotopes are unstable isotopes whose neutron/proton ratio differs from its stability ratio.
- These isotopes will naturally decay and break down on their own.
- A nucleus with neutron/proton ratio combination which is different different from its stability ratio will be unstable and split into one or more other nuclei.
- This is accompanied by the emission of small energetic particles.

The percentage of the mass of cellulose can be calculated by dividing the mass of the mass of cellulose in the sample by the total mass of the sample and then multiplying the output by 100 to get the percentage.
Mass of cellulose in sample = 0.38 grams
Total mass of sample = 3.35 + 0.38 + 8.76 = 12.49 grams
mass percent of cellulose = (0.38/12.49) x 100 = 3.0424%
