Okay happy to help<3
so the answer is C beacuse the fricton is making the ball roll smoothly on the wooden floor
good luck :)
Pros- We wouldn't need to use fossil fuels as much (which we have a limited supply of) and we have an unlimited supply when using Biomass as enegy.
It actually produces more oxygen when growing biomass crops and uses up carbon dioxide.
While for cons...
There's more work when it comes to growing and handling these crops, and this lifestyle in general.
more money and resources that we do not always have.
We don't always have a certain animal waste - which can slow down the process a little more if there's not enough of a certain thing. But of course referencing the pro side of things - we will always be able to produce biomass energy through things such as dead plants, etc.
I hope this helps, and you pass! Good luck, rockstar! (:
Alkanes represent one family of organic compounds that is composed of carbon and hydrogen.
Alkanes are organic compounds that solely have hydrogen and carbon atoms in single bonds and do not have any additional functional groups. Alkanes can be divided into three groups: cycloalkanes, branched alkanes, and linear straight-chain alkanes.
The general formula for alkanes is CnH2n+2. Alkanes are also saturable hydrocarbons. Cyclic hydrocarbons like cycloalkanes have rings-shaped arrangements of their carbon atoms.
Therefore, Alkanes are an example of an organic chemical family made of carbon and hydrogen.

Answer:
Solutions are always homogeneous.
Explanation:
Solution:
Solution are considered homogeneous because in solution the ratio of solute and solvent remain the same throughout the solution. Both solute and solvent are chemically combined and form a new substance.
In solution the particles of solute can not be seen through naked eye.
When the light is passed through the solution it can not scattered.
Example:
When salt is dissolve in water it makes a solution.
The solution also exist in gaseous form. For example oxygen and many other gases dissolved in nitrogen also form a solution.
Mixture:
In mixture substance are physically combined. In mixture every every individual particle retain their properties.
It can be consist of solid, liquid and gas.
Examples:
Sand in water is also a mixture.
Oil in water form mixture.
