Answer:
9.00 atm
For total pressure, you would add all the pressures together
<em><u>Voltaic cells convert chemical energy to electrical energy by means of an oxidation-reduction reaction. Electrolytic cells convert electrical energy to chemical energy, so they are the opposite of voltaic cells. ... This is because the sites of oxidation (the anode) and reduction (the cathode) are switched.</u></em>
Answer:
7.00
Explanation:
When the solutions are mixed, the HCl dissociates to form the ions H+ and Cl-. The ion H+ will react with the NH3 to form NH4+. The stoichiometry for this is 1 mol of HCl to 1 mol of H+ to 1 mol of Cl-, and 1 mol of H+ to 1 mol of NH3 to 1 mol of NH4+.
First, let's find the number of moles of each one of them, multiplying the concentration by the volume:
nH+ = 0.15 M * 25 mL = 3.75 mmol
nNH3 = 0.52 M * 25 mL = 13 mmol
So, all the H+ is consumed, and the neutralization is completed, thus pH will be the pH of the solvent (water), pH = 7.00.
Among these three halogen Bromine has the greatest atomic radius. As Bromine is present in 4rth period it outermost electrons are present in 4rth shell, so greater the number of shells greater is the size of an atom. While, in case of chlorine and fluorine they are present in group 3 and 2 respectively.
Answer:The sun creates energy through nuclear fusion. Kinetic energy creates heat and light.
