A test tube containing a mixture of compound x,y,and a very small amount of z weight 27.8645 g. The tube is emptied into a beaker and the empty tube is reweighed giving a value of 12.7472g.the mixture is separated into tow components by dissolving in water filtering off the insoluble material (component x)and then crystallizing one component (y)from the filtrate. The following data was obtained mass of filter paper /Lg.watch glass 13.1245g /mass of filter paper/Lg.watch glass+x 23.5899g /mass of filer paper/Sm.watch glass 9.4332g /Mass of filter paper/Sm.watch glass+y 12.1622g . Calculate the following 1. mass of sample ? 2. Mass of x recovered? 3. Mass of y recovered ?4.% X in the sample? 5. %y in the sample? 6. Assuming the actual composition is 69.75%X and 30.25%Y calculate the %error for each component. Indicate if the % Error represents a high or low error relative to the accepted values.

My samsung cop-365w says there is an error and I need to replace or install waste toner container - all my toners have high percentages - how can i make it work?


The sensor seems to send light through 3 small, clear "windows" on the left side of the waste container. I emptied the small amount of waste into a plastic bag for disposal and then used compressed air (outside) to blow out the remainder of the container, making sure the windows were clear. Presto! All good in the hood.

Whats a beaker


beakers are generally used for measureing small amounts of water
or other liquids for scientific purposes or any time precise control is
required. These clear containers ( also called graduates) are marked
like a kithen measuring cup but FAR more accurate.

Ice forms on the bottom shelf of the frost free freezer. We have no ice maker. What could be wrong? It's seven years old. It's a Whirlpool


I expect that when you check - the drain tube behind the inside back wall of the freezer compartment is clogged with debris and / or ice.

First, disconnect the the fridge from power at the plug.

Inspect the evaporator pan under the fridge. It is probably dry. If not, empty it and replace it.

Gather some towels & rags, a wet vac if you have one and a blow dryer to defrost and soak up / pick up melting ice. Also get a flexible piece of wire (coat hanger will do), turkey baster and a pail or container. A small amount of bleach will be needed, too.

You'll have to empty the freezer compartment of food and remove the back panel to gain access to the pan and drain. Some freezers have a plastic shelf pan that covers and is screwed to the freezer floor - if yours does, you should remove it, too. Keep clear of the coil, heater and controls that are protected by the panel. Plan on two - three hours to do the work, and an additional 2+ hours for the freezer to get cold again if all goes well. It will take much longer if you do not accelerate the defrost process (chipping, use of a blow dryer, etc.). If you can store food in a neighbor's freezer - that will be ideal.

Next, defrost the freezer. CAREFULLY chip away ice on the floor of the freezer. Do no chip in the area that was behind the back panel. Direct the hot air from the blow dryer at the ice in this area instead. Use towels and wet vac to pick up the water. Fill the container with hot water, and fill the turkey baster with the hot water and discharge the hot water at the ice / drain opening to speed the defrost process. Try to keep splashing to a minimum. Remove the blow dryer from this area when using hot water to melt the ice. Once the ice ice clear, check the evaporator pan again. Carefully remove it. If no water is present, the tube is still blocked. Replace the pan and continue to melt ice in the drain and check again. Repeat as needed. it is possible that a spider has taken up residence in the drain pipe - or there is some mold growing inside it. Use the coat hanger to gently "snake" down the tube to clear any obstruction. Once water begins appearing in the evaporator pan, empty it again and replace.

Mix up 4 ounces or so of water and 1 once of bleach and draw into the turkey baster. Place the opening as close to the drain opening as possible and gently squeeze the mixture into the drain. The mixture will kill any mold, spider, etc. that has been growing in the tube.

Almost done, CAREFULLY remove the evaporator pan again after allowing enough time for the tube to drain and empty in sink. This is a bleach mixture so be extra careful not to spill anywhere that bleach will cause damage.

Lastly, clean up with disposable rags (don't ruin towels picking up the bleach mixture) and reassemble back panel and floor pan. Restock freezer and plug the fridge back into outlet.

I hope this helps & good luck. Please rate my replay. Thank you.

The empty container/pc light comes on after approx 5 mins of drying cycle even when the container is empty


at the back of the dryer there should be a plastic tube from top to bottom ( this is the overflow pipe from the water container that needs to be emptied after each use, if the container is allowed to fill up, the water gts picked up by this pipe and collects at the base of the machine, stupid idea, i know) undo the clip at the bottom and empty the tube, also, with the tube still of, tilt the dryer and if loads of water comes out where u disconnected the tube you just need to get the water out. re connect the tube and bobs your uncle. hope this helps. p.s u may want to remove the top cover ( 2 screws ) and blow down the tube to make sure it aint blocked. when re fitting the tube, dont be scared of bending it to get it back into the slot where it tucks into the machine

Small rip on seam of tahiti k79hf


Use JB WELD, this is a super strength epoxy you can get at your local hardware store.

How does it work?

J-B WELD is packaged in two tubes. One contains liquid steel/epoxy resin, and the other contains hardener. When mixed together in equal portions, a chemical reaction occurs that turns the mixture into a compound as hard and tough as steel -- and with similar properties.

My air conditioner is leaking water


The air conditioner have water runs into the plastic container and when the container is full of water the weight will switch off the whole unit until you empty this container.
The tube that deliever the water into this plastic container blocked up with dirt that stop the water runs into the container and overfill the condenser drain pan that water runs all over the floor. Clean this condenser pan outlet and the connecting tube then you will be ok.
