When working with a Bunsen burner what precautions should be taken with respect to your clothing and hair?

Explanation:

Place the Bunsen burner away from any overhead shelving, equipment or light fixtures by at least 12 inches.

Tie-back any long hair, dangling jewelry, or loose clothing.

Your personal appearance before you even light the flame is a key safety consideration. Anything that is loose or dangling can potentially come into contact with the flame. Wear clothing that fits snugly to reduce the chances of the material catching fire. Participants with long hair should secure it away from the face so it doesn't fall down into the flame. Remove any long jewelry that might reach the flame. Wear goggles when using the flame, especially if you're heating a glass container or using chemicals.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
