The negative impact of the hydroelectric dam is local drought and massive flood by dam breakage.
The hydroelectric dam is the local water storage body that is used to convert the energy of the water to electrical energy. The plants are a huge source of electricity.
<h3>What is the dam's negative impact?</h3>
The dam is prepared in order to collect the local water in the bodies for the production of electricity. The collection of water required a larger force and pressure-bearing ability, thus dams are constructed with high-quality material.
The dams provide hydroelectricity, but the collection of water has been caused by the local drought conditions in the area. The dam breakage leads to massive floods as well.

Answer:
2HNO3 + Ca(OH)2 ===> Ca(NO3)2 + 2H2O
Explanation:
This a neutralisation reaction. The first thing to note is that this type of reaction forms salt and water.
Note that the formula of water is H2O. So write this at the right hand side.
==> H2O
Next note that the salt should contain the acid radical (NO3) and the metallic part of the base (Ca) written well following the rule for writing chemical equation; thus
==> Ca(NO3)2 + H2O
The next step is to write the reactants at the right hand side of the equation;
HNO3 + Ca(OH)2 ==> Ca(NO3)2 + H2O
The final step is to count the number of atoms in each side of the equation to make sure they are equal and balanced.
In the above equation, H atoms are three at the left hand side add 2 to to H- containig compound on both side as to balance up. Thus
2HNO3 + Ca(OH)2 ===> Ca(NO3)2 + 2H2O
The equation 2HNO3 + Ca(OH)2 ===> Ca(NO3)2 + 2H2O is balance.
Answer:
C = (5/9) F - (160/9)
They both read equal at Z = - 40
Explanation:
We are looking for a linear function so we can write the following condition
Y = aX + b
Applying it to the exercise we got C = a F + b
Let's use the facts that C = 0 when F = 32 and C = 100 when F = 212
0 = 32 a + b (1)
100 = 212 a + b (2)
From (1) b = - 32 a , when we replace this in (2) we obtain a = (5/9)
and b = - (5/9)32 = - 160/9
Finally the linear function is C = (5/9) F - (160/9)
Both readings are equal at a Z number so
Z = (5/9) Z - 160/9
(4/9) Z = -160/9 and Z = - 40
Answer:
Explanation:
Hello.
In this case, since the acid is monoprotic and the KOH has one hydroxyl ion only, we can see that at the equivalence point the moles of both of them are the same:
Thus, since we are given 1.70 g of the acid, we compute the moles of acid that were titrated:
Which equal the moles of KOH. In such a way, since the molarity is defined as moles over liters (M=n/V), the liters are moles over molarity (V=n/M), thus, the resulting volume is:
Best regards!
