The correct response is A. The inner she'll contains 2 electrons and the outer shell contains 4 electrons.
Answer:
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat capacity which we'll refer to as simply "heat capacity", meaning it takes more energy to increase the temperature of water compared to other substances.
Explanation:
Area measured in squares (or square units). We can count the squares or we can take the length and the width multiplication. The rectangle above has an area of 15 square units.
Answer:
The temperature would be 304, 87 K
Explanation:
We use the formula PV= nRT:
T= PV/nR = 1,00 atm x 100L /4,00 mol x 0,082 l atm/K mol=<em>304, 87 K</em>
Answer:
Electron loss is always associated with an increase in oxidation number- True
An exothermic reaction occurs when the energy required to break bonds in reactants is less than the energy released by bond formation in the products. True
The concentrations of pure liquids and pure solids are never included in an equilibrium constant expression because such concentrations never change. True
Explanation:
Oxidation implies loss of electrons. When a specie looses electrons, its oxidation number increases. For instance; Fe(s) -----> Fe^2+(aq) + 2e implies an increase in oxidation number of Fe from 0 to +2.
In an exothermic reaction, the energy required to break the bonds in the reactants is less than the energy released when new bonds form in the products.
We do not include the concentrations of pure liquids and pure solids in the equilibrium constant expression because the concentration of these do not change significantly throughout the reaction.
