How would an ash cloud from a volcano affect the flow of matter, cycling of energy, and organisms in an ecosystem?

1 answer:

3 0

Ash cloud from a volcano can greatly affect so many systems in the earth. The flow of matter is greatly affected by energy because without energy matter does not move. The cloud of valcano affects cycle of energy because it blocks the energy of the sun the enters the earth which will result to reducing temperature. Example of it the erruption of mt. pinatubo in ph, the earth temperature substanctailly reduces. The ecosystem will greatly be affected due to different temperature and different weather pattern that will occur that will be new to the orgnisms.

Molar mass in sulfuric acid

EleoNora [17]

Hey there!

Sulfuric acid: H₂SO₄

H: 2 x 1.008 = 2.016

S: 1 x 32.065 = 32.065

O: 4 x 16 = 64

--------------------------------

98.081 g/mol

The molar mass of sulfuric acid is 98.081 g/mol.

List the ions in solution in the electrolysis of conc.sodium chloride<br>

Licemer1 [7]

Chloride ions Cl –(aq) (from the dissolved sodium chloride) are discharged at the positive electrode as chlorine gas, Cl 2(g) sodium ions Na +(aq) (from the dissolved sodium chloride) and hydroxide ions OH –(aq) (from the water) stay behind - they form sodium hydroxide solution, NaOH(aq)

Different "substances" are forms of matter (having volume and taking up space) with different _______________ from each other. a

ExtremeBDS [4]

Answer:

properties

Explanation:

The properties of matter are the various ways in which matter behaves under certain circumstances.

Various substances have different volumes and shapes. These differences account for the various properties of matter.

Using the solubility graph place the substances in order from most soluble (#1) to least soluble at 40°C. KNO3, NaClO3,KBr, NaCl

mestny [16]

Answer:

NaClO₃ > KBr > KNO₃ > NaCl.

Explanation:

The attached file contains the graph with the solubility curves for the four substances, KNO₃, NaClO₃, KBr, NaCl.

To determine the solubility of each salt at a certain temperature, you read the temperature on the horizontal axis, labeled Temperature (ºC), and move upward up to intersecting the curve of the corresponding salt. Then, move horizontally up to insersceting the vertical axis, labeled Solubility (g/100g of H₂O), to read the solubility.

The higher the reading on the vertical axis, the higher the solubility.

The red vertical line that I added is at a temperature of 40ºC.

The number in blue indicate the order in which the solubility curves are intersected at that temperature:

4: NaCl: this is the lowest solubility
3: KNO₃: this is the second lowest solubility
2: KBr: this is the third lowest solubility
1: NaClO₃: this is the highest solubility.

Thus, the rank, from most soluble to least soluble is:

NaClO₃ > KBr > KNO₃ > NaCl.
