Answer:
4p
Explanation:
3s < 3p < 4s < 4p
This arrangement is in order of increasing energy.
This explains that, 4p is the highest energy level you can reach.
Covalent network crystals usually have the highest melting points and boiling points.
Answer:
higher, left
Explanation:
Given that the reaction consumes 462 kJ of energy. It means that the reaction is a endothermic reaction.
In the energy profile of the endothermic diagrams, The reactants are at a very low level as compared to the products and hence, energy is supplied to overcome this difference.
Hence, The energy levels of products are <u>higher</u> than the energy level of reactant.
Hence, already stated, heat is required by the reaction and thus heat is written to the reactant side which is to the <u>left</u> side of the equation.
Answer:
b. ph is greatet than 7
Explanation:
ph=7 neutral
ph=7-14 basicity as you go up increase basicity
ph=0-7 acodity as you go down increasing acidity
