An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Dude, writing someone else’s story or essay isn’t allowed, so i’ll just give some pointers
so the dude on the throne, a monarch, most likely the king, has a diamond or some other precious object in his hand. meanwhile, there’s a dude sitting on the floor, he looks unhappy, distressed, and maybe a little surprised. so what do you think happened to get to this point? what or who gave the king the diamond? why is the dude on the floor upset? then what’s going to happen? what’s the upset dude gonna
do? what’s the king gonna do? think of answers to the questions and it should start to form
pH scale is used to measure the acidity or alkalinity on a scale of 0-14 where 0-6.9 is the acidic region , 7.1-14 is the basic region and 7 is for the neutral substance. We can calculate the concentration of proton from pH.
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
where ![[H^+]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D)
is the concentration of proton
As per the question ,the pH of coffee is 5.6 and we need to find the concentration of proton so putting the values in the above equation, we get
![5.6=-log[H^+]](https://tex.z-dn.net/?f=5.6%3D-log%5BH%5E%2B%5D)
![-5.6=log[H^+]](https://tex.z-dn.net/?f=-5.6%3Dlog%5BH%5E%2B%5D)
![antilog(-5.6)= [H^+]](https://tex.z-dn.net/?f=antilog%28-5.6%29%3D%20%5BH%5E%2B%5D)
![[H^+]= 2.511\times10^-^6 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D%202.511%5Ctimes10%5E-%5E6%20M)
During most processes, energy is exchanged between the system and the surroundings. If the system loses a certain amount of energy, that same amount of energy is gained by the surroundings. ... for an exothermic process is negative because the system is losing heat.
