If the humidity is high enough we may notice fumes rising out of the mixture containing Br solution. The fumes produced are HBr fumes.

What is hydrogen bromide? </h3>
Hydrogen bromide (HBr) is a corrosive and toxic gas. It can be fatal if it is inhaled. It is very corrosive to our respiratory system, to our eyes, and when it is in contact with skin. When it is in mist form or in a liquid form it will cause burns to all tissue if it falls upon.
<h3>Why fumes are produced? </h3>
Hydrogen Bromide is a highly irritating, corrosive, nonflammable gas having a pungent odor at room temperature. It will fume in air which have high humidity because formation of hydrobromic acid takes place; it is the diatomic molecule.
Under ordinary conditions hydrogen bromide is a gas but it can be converted into liquid. Hydrobromic acid is then formed after hydrogen bromide is dissolved in water.
Thus we concluded that the fumes produced when bromine solution is in contact with moist air is HBr fumes.

Answer:75%
Explanation:
First, the balanced reaction equation must be written out clearly as a guide to solving the problem. The molar masses of H3PO4 and K3PO4 are then calculated as they will be consistently required in solving the problem. The theoretical yield is obtained from the amount of H3PO4 reacted. Since 1 mole of H3PO4 yields 1 mole of K3PO4, 0.05 moles of H3PO4 yields 0.05 moles of K3PO4. The mass of K3PO4 is produced is then the product of 0.05 and it molar mass hence the theoretical yield. The % yield is calculated as shown.
There is a thing called gravity. Gravity in the earth causes anything to stay down. There was an experiment a person held a plastic box with bricks on earth. It was really hard to pick it up. Then in the ISS (International Space Station) the same person help and it was so much easier no hardship at all, even a baby can do it!!

Answer: An element os made up of one kind of atom.
Explanation: Dalton's concept states that all atoms of an element is identical.
