Why does toothpaste contain a mild alkali?
Toothpaste contains alkali to neutralise the acid your teeth make so that you don't have to get fillings but it can't be too strong or it can damage your teeth too and also alkali's taste nasty.
Is baking soda safe for brushing teeth?
Yes, and very helpful too. If you put it on your teeth , mixing it with toothpaste , it is a great way to whiten and remove stains from your teeth!
Is a halogen gas that is yellow and explosive?
Fluorine is a pale yellow gas and very reactive. Chlorine is a pale green - which could look yellow depending on the lighting. it too is highly reactive. Of the two, you would probably be looking for fluorine as the best answer.
Why does fluorine bond with xenon but not argon?
Because the xenon atom's electrons in its lower orbitals (5s and 5p) are promoted to a higher shell (5d). This allows the fluorine to bond with these unpaired electrons. Argon would have to promote 3s and 3p to 3d (too high of an energy gap).See the link below.
Calculate the volume of F2 gas at stp produced by the electrolysis of 8.2g of KF?
The gram formula mass of KF = 39.098 + 18.999 = 58.097. Therefore, 8.2 g of KF contains 8.2/58.097 = 0.141 mole of fluorine atoms. Each mole of F2 requires two fluorine atoms, so that 0.070 moles of fluorine gas will result. An ideal gas at stp occupies 22.4 liters per mole, so that the volume of gas produced will be about 0.070 X 22.4 = 1.6 liters to the justified number of significant figures, unless fluorine gas at stp deviates too much from ideality.
What family does fluorine belong too?
Halogen
Fluorine does not form oxiacids- why?
Fluorine is too strongly electronegative to donate electrons to any other atom.
What will coke do to your teeth?
Coco-Cola will make your teeth become kinda yellowish-brown if the soda touches your teeth too much...I suggest you use a straw
What are the effects on teeth from soda?
Loss of tooth enamel which make you lose your teeth quicker so try not to drink too much.
Why does toothpaste contain a mild alkali?
Toothpaste contains alkali to neutralise the acid your teeth make so that you don't have to get fillings but it can't be too strong or it can damage your teeth too and also alkali's taste nasty.
Is brushing for too long bad for teeth?
It probably is not bad for you but if you brush your teeth too hard AND too long then that's too bad for you.
Can a salamander bite a human?
salamanders do bite but they wont if you dont make them mad
Why do baby rabbits use their teeth?
too where there teeth down
Is teeth have bones too?
Yes. Teeth are actually bones!
Where do you find fluorine?
You can find fluorine in toothpaste and in some city water supplies, because fluorine strengthens teeth and helps prevent tooth decay. It does not affect the taste, scent, or appearance of water, however. You can't find pure fluorine anywhere (well, other than from a specialty gas supplier), because it's too reactive to exist in nature. It reacts explosively with carbon and hydrocarbons, as the first person to try to make flurocarbons found out (he lost two labs that way).
Is metal nonresistant?
Care to clarify? The question is way too broad to give a useful answer. What type of metal? resistant or non-resistant to what?
Does candy shrink you?
No, candy is safe in that way, but if you have too much of it, it's not very good for your teeth and can make you fat.
