In order to expand agriculture and urban areas to meet increased demand for growing populations, water supplies often have to be diverted. In three to five sentences, construct a potential chain of consequences for what could happen when water is diverted from large bodies like lakes and rivers

Answers

Answer 1

Answer:

Decrease occur in the amount and flow of water bodies.

Explanation:

There is decrease in the amount and flow of water from water bodies such as rivers and lakes etc occur when the river is diverted from large water bodies because the water flows to the diverted sides and decrease occurs in the amount of water in the rivers and lakes. Those regions from where this river passes can also be negatively affected due to low amount of water they receives for their daily needs or for cultivation of crops so we can say that this diversion has adverse effect on other populations.

Answers

Answer: The volume of given ball is 21 L.

Explanation:

Given : Pressure = 1.0 atm, no. of moles = 0.85 mol

Temperature = [tex]25^{o}C = (25 + 273) K = 298 K[/tex]

According to the ideal gas equation, formula used is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

[tex]PV = nRT\\1.0 atm \times V = 0.85 mol \times 0.0821 Latm/mol K \times 298 K\\V = 21 L[/tex]

Thus, we can conclude that the volume is 21 L.

9.49.8 grams of Kl is dissolved in 1.00 kg of solvent. What is the molality?

Answers

Answer:

Molality = 9.498 mol k g − 1

Explanation:

A final way to express the concentration of a solution is by its molality. The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride.

molality = number of moles of solute/ mass of solvent in kg

number of moles of KI = mass of KI / molar mass of KI

number of moles of KI = 9.49.8 g / 1.00 g m o l − 1

number of moles of KI = 9.498 moles

molality = 9.498 moles / 1kg

molality = 9.498 mol k g − 1

Si la masa de una muestra de un compuesto Y es de 196 gramos y contiene 2 mol, la masa molar de Y es

Answers

Answer:

98 g/mol

Explanation:

La masa molar de un compuesto es la cantidad de materia (medida como masa) que hay en 1 mol de dicho compuesto. Por lo tanto, puede calcularse como sigue:

masa molar = masa/número moles

Tenemos los siguientes datos del compuesto Y:

masa Y = 196 g

número de moles de Y = 2 mol

Entonces, podemos calcular la masa molar de Y de la siguiente manera:

masa molar Y = (masa Y)/(número de moles de Y) = 196 g/2 mol = 98 g/mol

How many grams of oxygen are present in 10g of H2 SO4?

H2SO4 molecular weight is 98g/mol.

out of 98g 64g is due to oxygen

one mole of oxygen is 32g

Then 2moles of oxygen in H2SO4.

If you want to know the mass percent of a substance in a compound.

Simple formula:

Mass percent=Mass of the substance×100/Total mass of the compound

Ex:

Mass percent of oxygen in H2SO4=mass of the oxygen ×100/Total mass of the H2SO4

(i.e 16×4×100/98=65.3061%)

Here oxygen mass is multipled by 4 because there are 4 Oxygen atoms in H2SO4.

The greater the force that is applied to an object of a given mass, the more the object will accelerate. The greater the mass of an object, the less it will accelerate when a given force is applied.

Answer:133.4

Explanation: Explanation:

Molarity is number of moles of solute divided by number of litres of solution.

Rearrange for V to give

Number of moles of KCl is the mass divided by the molar mass of KCl which is 75.5 g/mol, so (5/75.5) = 0.0667 moles.

Now plug in the numbers:

0.0667

So you need to add 0.1334 litres of 133.4

A sample of gas as a volume of 425 mL at 25°C at and 760 tour what volume with this gas sample have at STP

Answers

Answer:

[tex]\Rightarrow V_2 = 389mL[/tex]

Explanation:

To solve this question, we could use Charles' law since both the number of mole and pressure are constant

At STP pressure P = 760 tor and Temperature = 273K

V1 =425mL, T1 =298K and T2 =273K

and [tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]

[tex]\Rightarrow V_2 =T_2\times\frac{V_1}{T_1}[/tex]

[tex]\Rightarrow V_2 =273\times\frac{425}{298}[/tex]

Therefore, [tex]\Rightarrow V_2 = 389mL[/tex]

How many calories of heat were added to 167.9 g of water to raise its temperature from 25oC to 55oC?

Answers

Answer:

Q = 5036.9 calories

Explanation:

Given that,

Mass, m = 167.9 g

The temperature raises from 25°C to 55°C.

The specific heat of water,c = 4.184 J/g °C

We need to find the heat added to water. We know that,

[tex]Q=mc\Delta T\\\\=167.9 \times 4.184\times (55-25)\\\\=21074.8\ J[/tex]

Q = 5036.9 calories

So, 5036.9 calories of heat is added.

If 4.04g of h2 gas react with oxygen gas to create 36.36g of water, how many grams of oxygen reacted?

Answers

Answer:

gO₂ = 32.32 g

Explanation:

In this case, let's write the general equation:

2H₂ + O₂ -------> 2H₂O

In this case, we can use the 1° law, which is mass conservation. If the product has 36.36 g of water, then in the reactants we should have the same 36.36 g.

According to this, we already have 4.04 of hydrogen, then the remaining to reach the 36.36 g would be:

gO₂ = 36.36 - 4.04

gO₂ = 32.32 g

What is the purpose of a buffer?

Answers

The main purpose of a buffer solution is just to resist the change in pH so that the pH of the solution won't be much affected when we add an acid or base into it. The added acid or base is neutralized.

Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.
