How is gold extracted from Auric chloride?
1st dilute A c with 2parts water let sit so clorine evaporats 2nd use supersatured solution of sodiummetabisulfite (smb) 3rd add smb to auric chloride a little at a time and let stand as gold oxide presipatates out of solution now the brown at the bottom is gold oxide next amalgamate with borax and lots of heat voala shyknee gold stuff
Heat-treatment of 6000 series alloy?
Yes, 6000 series aluminum is heat treated with various methods. for Example. A "natural age" is used to achieve a T4 state in certain alloys by allowing the material to sit. However the typical method of ageing an aluminum extrusion is to temper it in an age oven by "baking" the aluminum for a determined amount of time at a specific temperature.
What does sit back and steam mean?
That means your a bit angry so you sit on a chair and settle yourself.
Why do Styrofoam cups keep liquid warmer then plastic cups?
This experiment works by assuming a heat balance. You assume that all of the heat in the iron goes into the water and that none of it leaves the system, so you want your experimental apparatus to be as insulating as possible.If you use a cup with poorer insulative properties, you will estimate a lower value for the specific heat of iron. The styrofoam cup is not a perfect insulator, but it is better than plastic or ceramic.You can get a feel for this by pouring three cups of kettle water into plastic, ceramic and styrofoam cups. Leave them sit for a set time. Which one feels the hottest? That one is the best insulator. Which one feels the coolest? That one is the poorest insulator.
How is heat created?
Matter is made up of atoms and molecules (groupings of atoms) and these atoms and molecules are constantly jiggling around, bumping into each other. When the molecules (for example a water molecule in the air) bump into our skin, there is a transfer of energy. If they hit our skin with less force than the molecules making up our skin already are hitting each other with, our skin-molecules will go a bit slower, and the other molecules will go a bit faster after the collision, and we will feel colder. If they hit with more force than the skin-molecules had, the skin-molecules will go faster and we will feel warmer. The energy that speeds the atoms and molecules up in the first place comes from many, many different sources. For example when you burn wood, the chemical reaction between the wood and the oxygen in the air to produce ash, CO2 and water spits out the new molecules with a pretty decent force, and it is therefore not smart to hold a burning log in your hand. They get such great speed that they begin to glow, what we see as a flame (a phenomenon that has to do with electromagnetism). When this light hits your body, the molecules in your skin absorb it and starts to jiggle faster, which is why you can feel the heat from a fire even when you are not touching any of the fast molecules from the reaction. This is the same reason why you want to sit in the shade on a hot summer day. You want to absorb as little of the light from the sun as possible. The thing that makes the sun so incredibly hot in the first place is another way to get heat: fusion. Here several light atoms combine to create a heavier atom, and afterwards spit out a particle with insane speed, enough to heat the interior of the sun to millions of degrees. In the end almost every physical process creates some amount of heat. Rubbing your hands together takes chemical energy stored in your muscles and turns it into heat, both in the muscles themselves and in the skin of your hands. Stopping a car takes the kinetic-, movement-energy of the car, and turns it into heat in the breaks. Reading this sentence takes energy stored in chemicals delivered to your nerve-cells by your blood and turns it first into heat and electrical impulses, which are your thoughts, before they too ultimately become heat due to the electrical resistance in your brain.
Why does the jacks sit next to you?
Because they feel sorry for him.
Why should kids be able to sit anywere at lunch?
They should not be allowed to sit anywhere, what if they sat on a road, or on a campfire. Children need to be kept safe
Can you sit a fridge next to a freezer?
Yes, no problem, as long as there is sufficient air flow behind them to dissipate the heat.
What type of heat transfer are you experiencing when you sit next to a bright light?
Radiant. Consider the warmth you get from the Sun.
How do you know how a boy feel for you?
If a boy fancy you they will play with you, sit next to you, make you laugh and always make you happy.
Do you feel hot when you sit by a fire because of ultaviolet radiation?
it's the heat coming off of the fire that's making you warm
How do you get the girl you like to sit with you without saying anything?
Fined out what she likes. Then find out if she likes you. Then she might feel comfertable sitting next to you.
How can your body lose heat by conduction?
When you touch something that is colder than your body temperature, the heat from your body will transfer to the colder item. The temperature of your body and the item you touched tries to equalize. The perfect example of this is when you sit on one end of a couch for a while. When you get up and put one hand on the area where you sat and the other hand on an area where you did not sit you will feel difference in warmth between the two places. The hand that is on the place where you sat should feel warmer than the hand where you did not sit. This is also why when you sit on cement or a rock that has been in the shade you will start to feel much cooler.
How can you get a girl to sit next to you at the movies in 6th grade?
ask her to, or ask if you can sit next to her.
When was Can I Sit Next to You Girl created?

Is Hardwood smoke toxic?
To a varying degree, all smoke is toxic to humans, but not enough that you can't sit around a campfire and get a dose of it now and then.
What it feels like to sit by a campfire?
It feels warm and calm but when your face gets the temperature hot, you would feel a little bit uncomfortable. I am not sure of a lot of details but I am telling this answer because I have a fireplace at my house. I am sorry if I had a mistake, but it is a good question. Keep on using your skills!!!!!!!!
