Answer:
Drought can affect water sources, land, fish and wildlife and plant communities, and can also affect trees directly by slowing or arresting growth, and causing injury or death
Explanation:
<u>Answer:</u> The rate law for the given chemical equation is
<u>Explanation:</u>
Rate law is defined as the expression that expresses the rate of the reaction in terms of the molar concentration of all the reactants each term raised to the power their stoichiometric coefficient in the given balanced chemical equation.
For the given balanced chemical equation:
Rate law expression for the reaction:
Order with respect to Li = 1
Order with respect to NaCl = 1
Hence, the rate law for the given chemical equation is
Answer : The enthalpy change for the reaction is, 201.9 kJ
Explanation :
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The balanced reaction of will be,
The intermediate balanced chemical reaction will be,
(1)
(2)
(3)
(4)
Now we will multiply the reaction 1 by 2, revere the reaction 2, reverse and half the reaction 3 and 4 then adding all the equations, we get :
(1)
(2)
(3)
(4)
The expression for enthalpy of the reaction will be,
Therefore, the enthalpy change for the reaction is, 201.9 kJ
Answer:
The first row fits in period 2
The second row fits in period 3
Explanation:
Elements arranged vertically in the periodic table in groups that share similar chemical properties.
Elements are also organized horizontally in rows or periods
The length of each period is determined by the number of electrons that can occupy the sublevels being filled in that period.
