First, we calculate the kilojoules of energy per hour:
Energy per hour = 2070 x 1.055
Energy per hour = 2183.85 kJ / hr = 2.18385 MJ / hr
Hours in a year = 365 days per year x 24 hours per day
Hours in a year = 8760 hours
Energy output per year = 2.18385 x 8760
Energy output per year = 19,130 MJ per year
The anwser is atoms are destroyed
Answer:
H must pair with Fluorine, Oxygen, or Nitrogen
Explanation:
water has polar covalent bonds, the intermolecular forces are hydrogen bonds, London and Dipole forces
The atomic theory changed because as time passed by our technolgy has been improving our ability to find answers to these theories.
Answer:
The total mass of the solution = 99.7 g
Note: The question is incomplete. The complete question is given below:
<em>A "coffee-cup" calorimetry experiment is run for the dissolution of 2.5 g of lithium nitrate placed into 97.2 mL of water. The temperature of the solution is initially at 23.5oC. After the reaction takes place, the temperature of the solution is 28.3 oC. </em>
<em>1. Using a density of 1.0 g/mL for the water added and adding in the mass of the lithium nitrate, what is the total mass of the solution and solid?</em>
Explanation:
mass = density * volume
density of water = 1.0 g/mL; volume of water = 97.2 mL
mass of water = 1.0 g/L * 97.2 mL
mass of water = 97.2 g
mass of lithium nitrate = 2.5 g
A solution is made by dissolving a solute (usually solid) in a solvent (usually a liquid). The solute in this reaction is lithium nitrate and the solvent is water.
Total mass of solution = mass of water + mass of lithium nitrate
Total mass of solution = 97.2 g + 2.5 g = 99.7 g
Therefore, total mass of the solution = 99.7 g
