The electron has a negative charge
the neutron has a neutral charge
the proton has a positive charge
i remember this like
neutron-NEUtral
proton-POsitive
electron-electricity hurts it always has NEGATIVE effects
an atmosphere is the masses of gas surrounding a body
Answer:
So, Luke and Sian has to increase the pH of the soil by adding base to it.
Explanation:
The pH is defined as the negative logarithm of the hydrogen ion concentration in their aqueous solution.
- With increase in hydrogen ion concentration the pH value decreases.
- With decrease in hydrogen ion concentration the pH value increases.
The pH of the soil after testing it on a kit comes out be 5.0, but they both need pH of the soil to 6.5.
Comparison of pH of soil:
= 5.0 < 6.5
= High hydrogen ion concentration > High hydrogen ion concentration
So, Luke and Sian has to increase the pH of the soil by adding base .Doing so will decrease the hydrogen ion concentration in the soil (where as addition of acid lower the pH of soil).
B:Molecules must collide.
Why: They have to collide so the chemical bonds can break.
Albert Einstein wrote this quote. Given that he was a scientist, he found the world of religion beautiful. The mystery of life. Almost every religion out there contradicts itself but still believes in something so supernatural that they have come to rule the universe. It is a reflection of the universe which we cannot perceive. The beautiful mystery not only is the world of religion but the very structure of it. Even as a scientist – someone who believed that the world may be more functional scientifically rather than being controlled by the religious beliefs of people – if you can't stand in awe and wonder at the mystery of life, then you are in a position of great danger as you live a life you don't even wonder about. "His eyes are closed", meaning he is walking blindly through life not trying to understand the beautiful mystery of life that comes with living it.
Hope that helped. If you want to change some of the words to make it sound more grade 6 level, you are welcome to do so.
