Answer:
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. ... Methane combining with 2 oxygen to form carbon dioxide, water and heat.
Answer:
There are several ways of measuring the rate of photosynthesis in the lab. These include:
the rate of oxygen output
the rate of carbon dioxide uptake
the rate of carbohydrate production
These are not perfect methods as the plant will also be respiring, which will use up some oxygen and carbohydrate and increase carbon dioxide output.
Several factors can affect the rate of photosynthesis:
light intensity
carbon dioxide concentration
temperature
The amount of chlorophyll also affects the rate of photosynthesis:
plants in lighting conditions unfavourable for photosynthesis may synthesise more chlorophyll, to absorb the light required
the effects of some plant diseases affect the amount of chlorophyll, and therefore the ability of a plant to photosynthesise

The ability of a liquid to flow up a narrow tube which is unassisted against the gravity of the attraction between molecules of the same substance. The curvature which is of the surface of a liquid at the interface with the container, the attraction between dissimilar molecules for the resistance of a liquid to flow the elasticity of surface layer of liquid because of the liquid trying to minimize its surface area.
Answer:
34- Solid
35-Metals form metallic bonds releasing one or more valence electrons to form a common electron reservoir which contains free mobile elactrons who will conduct electricity well.
36 When the cation is formed electrons are removed and the effective positive neuclear charge increases and it makes the remaining electrons accumulate around the neucleous making the cationic radius smaller than that of the atom
