The mass of the product in a chemical reaction must be equal the mass of the reactants.
PV=nRT<=> P=nRT/V=2,40*R*(273+97)/45 atm.
Calculate it. R is a number that is given, find it and use your math to solve.
Answer:the second one
Explanation:,Hydrogen bonding is a special type of dipole-dipole attraction between molecules ,not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
Answer:
Potassium
Explanation:
As potassium is larger than sodium, potassium's valence electron is at a greater distance from the attractive nucleus and is so removed more easily than sodium's valence electron. As it is removed more easily, it requires less energy, and can be said to be more reactive.
Answer:
The mass of Benadryl that should be given to the dog is 58.6 mg
Explanation:
First, let´s convert the mass of the dog to pounds:
1 pound = 0.454 kg. Then:
26.6 kg * (1 pound / 0.454 kg) = 58.6 pounds
Since the recommended dosage is 1 mg per pound, the mass of Benadryl that should be given to the dog is (58.6 pounds * (1 mg / 1 pound)) 58.6 mg.
