Answers
Which of the following does not influence soil pH? a. rainfall b. hydroponic growth c. release of sulfur and nitrogen oxides into the air d. decomposition of organisms e. weathering of rock
So here we have a scale of phs and we're going to take a look at how the ph can affect different pieces of soil. So what happens is that the ph is going to affect how much minerals the soil can uh use or take up and so we have to make sure that the ph level is right and in the right environment. So take a look at a couple of different areas. Let's first look at drier areas. When I think of dry areas, I think of areas that have very little rainfall. So places like Arizona. So um anytime we have a drier regions they're going to have a typically a ph that is higher than seven. So it's going to be on this side of the scale and it tends to be alkaline in these levels here. So drier areas with less rainfall rainfall are going to have peaches that are above seven. So seven is right here neutral kind of the middle area. Now when it's tropical areas where there's lots of rainfall, Soil tends to be acidic so it's below seven and it's going to be on this side of the scale. So sit right over here and this is the weather that you're going to see from areas with lots of rainfall. So things like rainforest or tropical areas that experience very heavy rainfall throughout the year. Now what happens in these tropical areas is there's so much moisture going on that it causes really fast decaying of hummus. So what happens is the U. S. Is composed of organic material And so all this moisture is causing it to rapidly or very fast decompose. Now soil can influence if the plant roots use minerals. So we know that, so we know that depends on the soil environment. The minerals that are used up and taking up from the roots of plants can be affected in both of these different environments but know that minerals can actually be used from plants. Their roots can pick them up from rocks to or other smaller minerals. So it can use rocks as a source of minerals if needed.
So c a c 03 It can be heated and were able to generate C A. I was one of our products. So this reacts with eso to to generate cso three, where we have an assumed 70% yield in this case. So in this podcast we can look at calculating the mass of C A a C 03 that is required to remove our S 02 So our reaction is as follows we have C A. C 03 is an equilibrium of CEO at 302 so that's fully balanced. And then we take our CEO where we have a story geometric value of two with two units of aso to is an equilibrium A to C. A s at 302 So I've also included the overall combined equation below. So the mole's R C. A. C 03 that is needed is 1.25 times 10 to the power four miles. So then we use the relationship between moles on molecular weight where we can determine the molecular weight by just looking at the numbers on our periodic table and adding them all together for each atom in our compound of C A C 03 So we multiply our malls by RMR generate 1250.62 g that is needed.
So now we go to problem. 31. So 31. But we have to write chemical equation, right? This prided Apprentice it on limestone Qasem carbonate Course. Yes, Cos Scott, Come on. I even saw the which saw the wit base. So we have this our service here? No, no, we pay service and we had custom. So face it also solid. And we have hydrocarbon it asset. Right. So because this unstable when you say 02 Yes. Here. Evaporate and water. Right? And then this equation the I see. What do they ask us if a climb song sculpture were treated to farmer surfaced Layer podcasts? Um, sulfate could this how to slow down the first open secrets explained. Okay. And now you see the Russian We had access off as it is strong as it and couple nick asset is weak and sit. And the fresh on way favor to reduce quick base are strong base. A weak acid are weak base. So we have We can sit here. So the Russians on way favor to from the left of the rice. Then you say the reaction his favor to produce Ah, week asic. Right. So is always sheep from the left to the right. And now if you cover Qassam couple night with a cousin sulfide. So Carson's off. I will protect the surface of custom couple nights so the Russian cannot happen on. Then we'll continue to write. It will protect C I C o trees from reacting with several classic So yeah mm. On when you write question keeping my objection on ways favor to produce week base and we can see and then the anguish Jupiter. Right now you cover the Qassam couple of the limestone with risks. With this causes of Qasem, Sophie off, called the Russian cannot happen.
In this question For each of the following, we have to stay whether the solution at 25°C is sed neutral or basic. Okay, first if If the ph of the solution is less than seven, then the solution is a city. And if the ph of that solution is more than seven then the solution is basic. And if the ph is seven then the solution is neutral here. The first solution given is 0.1 Mueller's one more par. Later solution up try should young fast bear who's ph is given 12.0 since ph of this solution is more than seven. So the solution is basic solution is basic. Now the next one is 0.1 in solution of calcium chloride CSL two speeches given 7.0 since the ph of this solution in 7.0. Therefore this solution yes neutral. This solution is neutral. No, the next 10.2 m solution of copper sulfate whose ph is given 4.0 since ph is Less than seven. Therefore, the solution is acidic. The solution is a city. The last one is simple of Rainwater. Who's ph is given 5.7 here, since the Ph is less than seven. Therefore, rainwater simple is acidic rain water sample. Yes, acidic. Actually, I should write this rainwater simple his capacity.
