Question about Casio FX-270W Calculator

2 Answers

I have AP Chemistry homework that involves finding the pH level of a solution. I know the equation for solving the problem. However it requires my calculator and I do not know how to use the log feature on the calculator. I also want to know how I can change my answer to standard form using the Casio fx-270W Plus.

What is an antonym for equation


There are various ways that a mathematical expression fails to be an equation. It lacks a relational operator (symbol). It has a less than sign, or a greater than sign, or a combination of other symbols. If you language homework requires(?) that you find an antonym for equation, try non-equation.

What is the percentage increase of this equasion 5690+950=6600?


Math homework, but an English lesson involved: Proper spelling is "equation."

Offhand I see possibly that we need to set up to solve 5690/6600= X/100 and cross-multiply, then solve for X

Do again for 950/6600=Y/100 and cross multiply. Solve for Y.

At least we get to put something together that replaces the original equation with X%+Y%=100%

Now, I am leading up to Y% is the percentage change, but I need to bone-up on that point myself. Perhaps I have triggered the thought juices.

Otherwise chemistry fine?
whenever someone is vague about chemistry residual readings, but provide a pH reading, I'm always Leary.
  • bring pH up to 7.6
  • Balance Total Alkalinity at 120 ppm
  • Bring Hardness to at least 200 ppm
  • Keep Chlorine level at least 3.0 All the time
  • ISO Cyaniric acid / stabilizer at least 30, not exceeding 80 ppm
  • Use a Natural Clarifier weekly - rate = 1 ozs per 5000 gallons
  • Use Algaecide (not from Kmart!) weekly
  • Clean filter whenever pressure approaches 8# over starting
  • Filter for at least 1 turnover per day. This is usually 8 hours in most regions
Follow this, should be good

Having problems with metal staining. i was told that i should clean the heat exchanger. can i just take off the front header & flush the tubes with some d-lime. Thanks


There is a very specific method for cleaning heat exchanger tubing and using any acidic cleaner could potentially cause damage to the tubing, especially if it is erroded. As to metal staining in your tub... cleaning the heat exchanger is NOT the answer! If the staining is copper, then cleaning the heat exchanger is NOT going to correct the problem!. Your heat exchanger is likely copper and if it is the source of the copper staining, then the problem is NOT the heater, the problem is your water chemistry. In most pool service calls I have done, involving staining from copper or iron, the most common problem was low pH. If your test is showing a pH of lower than 7.2, then add pH increaser (baking soda) based on a base demand test. If after adding the needed amount of pH increaser, the pH remains below 7.2, then perform a pool stabilizer (cyanuric acid) test. If the results show higher than 80ppm, drain at least 50% of the volume and refill and retest again. A high stabilizer level in excess of 100ppm will result in a low pH and cause metals like copper to dissolve and stain the pool. Get the level down to around 30-40ppm if possible. Stabilizer is added to chlorine tablets to help hold chlorine in the water longer. You can unstabilized chlorine, but chlorine consumption is higher as a result. If the staining is copper, you should dismantle and inspect your heater for erosion and possible early stage leaks. Replacing the heat exchanger can be very costly. Proper preventive maintenance and chemistry balance will keep the staining issue under control. There are some products available on the market to assist with balance, staining treatment and overall chemistry control. I suggest looking at products by EasyCare, called Pooltec, Scaletec and Beautec. These may be beneficial for your situation.

Find the antilog on the TI-84 Plus for finding pH in chemistry problems


I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

Find the antilog on the TI-83 Plus for finding pH in chemistry problems


I reccently had the same problem, but I have a Ti-84 Plus,and I am disgusted by how poorly this matter is covered by Texas Intruments. Esp. since the solution is rather simple.

The antilog key is [2nd] [log] or the 10^x. On your screen it should apear as 10^( and then you just input the value that you want to find the antilog of.

When used to solve pH problems remember to input the pH value as a negative number, since pH= -log[H+] then [H+]= antilog(-pH).

Hope that helped))))) ^^
