From the table the enthalpies are negative meaning the reactions are exothermic where gaseous ions bind to form an ionic solid.Lattice Energy is a type of potential energy that may be referred to as the energy required to break apart an ionic solid and convert its component atoms into gaseous ions; where the lattice energy is always positive, since the will be an endothermic reactions. Lattice energy may be also be defined as the energy released when gaseous ions bind to form an ionic solid where the energy value will be negative since the reactions are exothermic.
Here are the key events listed in chronological order with
their corresponding year.
1. Hooke coins the word cell after viewing cork cells with
primitive microscope. (1665)
2. van Leeuwenhoek discovers bacteria with his improved
microscope. (1676)
3. Brown recognizes and names the cell nucleus. (1831)
4. Schleiden & Schwann propose cell theory. (1839)
5. Virchow describes cell division; proposes that all cells
arise from other cells. (1855)
<span>6. Pasteur disproves spontaneous generation and proposes germ
theory. (1861)</span>
Flat as more oxygen and water can react over it think of it like this would a cube rust faster than a sheet
Answer: The law of conservation of mass states that mass is neither created or destroyed, so the combined mass of all the products after the reaction will be the same as the mass of all the reactants and never more, but since the flask is not closed, the gases produced from the reaction will move into the atmosphere and the product left behind , the solids and/or liquids, will be the only products that you’ll end up weighing, meaning it’ll be less weight than the original reactants. The reason I’m interchanging weight and mass is because although weight changes with gravity, so long as the gravitational force stays constant throughout the experiment, it’s pretty much the same.
