Answer:
the salt is a solute in this instance
Answer:
A
Explanation:
OH is generally basic, while H is generally acidic so the greater the OH concentration, the more basic the solution will be.
Answer:
1.0625 g
Explanation:
Number of moles in 5g of NH4NO3 = 5.0g/80g/mol = 0.0625 moles
Again the balanced reaction equation is;
NH3 + HNO3 → NH4NO3
So,
1 mole of NH3 yields 1 mole of NH4NO3
x moles of NH3 yields 0.0625 moles of NH4NO3
x = 0.0625 moles of NH3
Mass of NH3 = number of moles * molar mass
Mass of NH3 = 0.0625 moles * 17g/mol
Mass of NH3 = 1.0625 g
Number one is the correct answer
Answer:
Electron gain enthalpy becomes more and more negative from left to right in a period. As we move across a period from left to right the atomic size decreases and the nuclear charge increases
