Answer:
spring tide
Explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tide
Answer:
Effective nuclear charge and ionization energy decreased down in the column.
Explanation:
Along Group:
As we move from top to bottom in group the atomic size increases with increase of atomic number. The electron is added into the next shell hence the valance electrons farther away from the nucleus and hold of nucleus become weaker on the valance electrons. The addition of electrons also increase the shielding and protect the outer electrons from the hold of nucleus. Thus it becomes easier to remove the electron from an atom and less energy is required that's why ionization energy decreases from top to bottom and effective nuclear charge also decrease because of shielding effect.
Along period:
As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons and shielding remain constant due to addition of electron in same shell. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases.
Answer:
3 Both mass and charge are conserved.
Explanation:
The equation of the reaction is;
Cu(s) + 2Ag+ (aq) → Cu2+ (aq) + 2Ag(s)
A redox reaction is an acronym for oxidation-reduction reaction. This refers to a reaction in which the oxidation number of one specie is increased while the oxidation number of the other specie is decreased.
This means that one specie looses electrons while the other specie gains electrons. Here, Cu(s) looses electrons while Ag+(aq) gains electrons from left to right in the reaction.
In a redox reaction, both mass and charge are conserved. This means that the total mass and charge on the reactants side is the same as the total mass and charge on the products side.
Answer:
A: plants give off water vapor as a waste product as they process energy
Explanation:
Evapotranspiration in plants is defined as the process whereby water is evaporated from its leaves through transpiration during the process of photosynthesis. Different factors like wind, humidity, temperature and availability of water could make it vary.
Comparing all the options, to this definition, the correct answer is Option A.
Answer:
If the pressure of the system increases then the boiling point will increase.
If the pressure of the system decreases then the boiling point will decrease. If there is no change in pressure then the boiling point will remain constant.
