Describe the sequence of events in the formation of an evaporite

1 answer:

3 0

- Water enter from creeks, bringing whatever material it has dissolved in its way

- The materials is being build up throughout time in the lake or sea, causing its salinity to increase

- when this saline solution is evaporated, the ions in the water precipitate, forming an evaporite

How many joules are required to boil 150. grams of water?

gizmo_the_mogwai [7]

Ans: 47,070 J

Thus, 47,070 J are needed to increase the temperature of 150 g of water from 25 degrees C to its boiling point of 100 degrees C. One can follow a similar procedure to determine the energy needed to heat water from one temperature to another.

1. AA, AAA, C and D cells all deliver the same voltage( 1.5V) when the batteries are fully charged. However,as the size of the b

tigry1 [53]

Answer:

A. The increase in size of the battery results in a smaller internal resistance and hence, a larger current delivery.

B. Zinc serves as the anode

Explanation:

A. The current that a battery can deliver is affected by the internal resistance of the battery.

The internal resistance resistance, r, is the resistance to flow of current within the battery. The smaller the internal resistance for a given emf, the more current and the more power the source can supply.

The relationship between current, I, emf, E, the external load ,R, and internal resistance is given by the equation:

I = E / (R + r)

The bigger the size of a battery, the smaller its internal resistance and thus, the larger the current the battery can deliver.

B. In a battery, the cathode is reduced by accepting electrons from the anode, while the anode is oxidized to zinc ion by giving up its electrons to the cathode.

From the equation of the reaction, metallic zinc is oxidized by giving up two electron to the cathode.

Zn(s) ----> Zn2+ + 2e-

Therefore, metallic zinc serves as the anode.

Starting with a vessel of temperature 50.1°C, a pressure of 6263.MmHg and volume 461.1mL, what is its final volume, in liters, i

il63 [147K]

Answer:

The value of final volume inside the vessel $V_{2}$ = 5.17 ml

Explanation:

Initial pressure $P_{1}$ = 6263 mm Hg = 8.24 atm = 835 K pa

Initial temperature $T_{1}$ = 50.1 ° c = 323.1 K

Initial volume $V_{1}$ = 461.1 ml = 0.0004611 $m^{3}$

Final temperature $T_{2}$ = - 95.8 ° c = 177.2 K

Finial pressure $P_{2}$ = 411 atm = 41644.6 K PA

We know that

$P_{1} \frac{V_{1} }{T_{1} } = P_{2} \frac{V_{2} }{T_{2} }$

Put all the values in the above equation

⇒ 835 × $\frac{0.0004611}{323.1}$ = 41644.6 × $\frac{V_{2} }{177.2}$

⇒ $V_{2}$ = 5.07 × $10^{-6}$ $m^{3}$

⇒ $V_{2}$ = 5.17 ml

This is the value of final volume inside the vessel.

If a 500 ml sample of water contains 2.6 x 10-6 g of iron, what is the concentration of iron in ppb?

Anastasy [175]

The concentration of iron in ppb is 5.2 ppb

In atmospheric chemistry, PPM( parts per million) and PPB( parts per billion) units are used to express the concentration of gases. PPB stands for parts per billion, while PPM stands for parts of gas per million parts of air.

2.6 × 10⁻⁶ grams of iron in 500 ml of water.

Now, converting milliliter into liter:

500 mL = 500 mL × ( 1L / 1000 mL ) = 0.5 L

Now for ppm, mass must be in mg.

2.6 × 10⁻⁶ grams = 2.6 × 10⁻⁶ grams × ( 1000 mg / 1 grams ) = 2.6 × 10⁻³ mg

Then, the concentration of iron in ppm will be:

2.6 × 10⁻³ mg / 0.5 L = 5.2 × 10⁻³ ppm

Now, 1 ppm = 1000 ppb

Therefore,

5.2 × 10⁻³ ppm × 10³ = 5.2 ppb
