Putting solar panels on houses is a great idea, for it provides a renewable source of energy and heat, which is the sun. It will help prevent pollution and the mass-use of non-renewable resources, such as fossil fuels, which are used and burned for energy.
Although, having solar panels, there will be some downsides. For example, solar panels can only receive energy during time where there is light from the sun, which is daylight. therefore, the solar panels will not and cannot be able to collect energy from the sun during night time. although, depending on the solar panels, some can store energy, from the sun, that can be used at night time, like as if you're charging a battery with energy from the sun for later use. one big problem is that, solar panels are not cheap and rather quite expensive, which not all homes and families can afford. although, through time, solar panels will get cheaper.
but, all in all, I believe that solar panels give a great contribution to Earth, thus I agree to the use of solar panels.
Answer:
The answer is c) charged balloon
Answer:
B
Explanation:
A chemical reaction equation is balanced if the number of atoms of each element on the right hand side of the reaction equation is the same as the number of atoms of the same element on the left hand side of the reaction equation.
By inspection, the chemical reaction written in the question is a balanced chemical reaction equation.
However, the statement in option B that more molecules of N2 are needed to produce NH3 than molecules of H2 is a false statement since only one mole of N2 and three moles of H2 are required to produce NH3 according to the reaction equation as written in the question.
