Explanation:
In order to balance a chemical equation, it is required that the number of reactant atoms or molecules should equal the number of product atoms or molecules.
For this, we first of all write the chemical formulas and symbols on both reactant and product side. Then we count the number of individual atom on the reactant and product side followed by multiplication or division of according to the count of respective atom.
For example,
Here the number of nitrogen atoms on reactant side should be equal to the number of nitrogen atoms on product side. Similarly, the number of hydrogen atoms on reactant side should be equal to the number of hydrogen atoms on product side. Only then this equation will be balanced.
Therefore, we can conclude that out of the given options, the statements which are not true are as follows.
- Subtract the total amount of elements from the products.
- Add all the elements together.
The following exist:
Artificial photosynthesis: Plants can photosynthesize, but we can do it artificially to power anything requiring energy.
Solar thermal energy or STE is a process where the light is reflected from a mirror or lense to heat up anything.
Photovoltaics or Heat collectors (Solar panels): they absorb the sun's electromagnetic energy and converts it into electricity.
All of these technologies are very similar to each other... this was a good question
Concept:
Significant Figures: In the measured value of a physical quantity, the number of digits about the correctness of which we are sure plus the next doubtful digit, are called Significant Figures.
There are certain values of physical quantities which are defined; like irrational numbers ∛2, √3, the speed of light ( 299792458... m/s), converted value of centimeter in to inches (2.54...), refractive index of the glass with respect to the water ( 1.333....) etc. These values are defined but they have no limit of significant figures because we can consider the measurement up to any extent which differ from the measurement to the measurement.
Answer:
The two most obvious ways to restore balance to carbon cycles are:
1. To move away from our dependence on fossil fuels.
2. To farm in ways that retain more carbon for longer periods than conventional farming methods currently do.
Explanation:
look up.
Answer:
lose
Explanation:
its lose because if its positive, assume the electron is a person who has already eaten, theyre full and dont want more, therefore they would want to lose the weight, so its lose.
