An earthquake causes a one 100 mile square area to be fractured into four different geographical areas. Two of the areas have a

river running through them, the other two have ponds. Which of the following is a likely scenario based on the new geography? Over time, the areas with the rivers will have less animals than the areas with the ponds. Within a couple years, the areas with the rivers will have many more plants than the areas with the ponds. Animals that need access to large quantities of salt water will be found in the area with the ponds. Flying animals will be able to cross back and forth between the two areas easily.

If it is a multiple answer question, then "The areas with the rivers will have the most plants" and " The areas with ponds will have more animals" would be your best answers. If it is a single answer question, then it would be best to go with the answer with 'The areas with the rivers will have more plant life",. The reason being, is that when there is a lot of water flow, there is more plant life around.

Answer:

Within a couple years, the areas with the rivers will have many more plants than the areas with the ponds.

Explanation:

The help of running water on the area will increase and sustain the new wildlife that the area will start to have, as a risponse to the new geographic area, the ponds unless they have a way to re-fill wouldn´t be of much help for the animals and plants around them, so within a couple of years the areas with the rivers will have many more plants than the areas with the ponds.

12. If the total pressure exerted by 3 gases is 45 atm and each individual gas has the
Bumek [7]

Answer:

Partial pressure for each of the three gases, in the mixture is 15 atm

Explanation:

Remember that the total pressure of a mixture, is the sum of partial pressures from the gases contained in the mixture.

Our total pressure = 45 atm

The 3 gases have the same pressure, so we can propose this equation:

3x = 45 atm

where x is the partial pressure for each of the three gases.

x = 45/3 → 15 atm

Classify unopened root beer as an element, a compound, a homogeneous mixture, or a heterogeneous mixture
maxonik [38]

The different state of material based on its ingredients are-

1. Compound: The compound is in which there are more than one molecule in which chemical bond is there.

2. Mixture: It is basically presence of two or more compounds in which there is no chemical bonds.

The mixture may be of two types (i) homogeneous and (ii) Heterogeneous. In the homogeneous mixture there is uniformity of the mixed compound (like air in water) and some chemical process is needed to separate the compounds. Whereas heterogeneous mixtures (like chalk in water) are easily separable by any physical process.

In the root beer which is a soft drink which is obtained in different flavor sometime with caffeine and without caffeine. The unopened bottle of root beer is homogeneous mixture.

Calculate the molar mass of cacl2
kirza4 [7]

Answer:

\boxed {\boxed {\sf 110.98 \ g/mol}}

Explanation:

The molar mass is the mass of a substance in grams per mole.

To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.

The compound given is:

CaCl_2

The compound has 1 Ca (calcium) and 2 Cl (chlorine).

 

Mass of Calcium

  • The molar mass of calcium is 40.08 g/mol
  • There is only one atom of Calcium in CaCl₂, so the number above is what we will use.

Mass of Chlorine

  • The molar mass of chlorine is 35.45 g/mol
  • There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2.
  • 35.45 * 2= 70.9 g/mol

Molar Mass of CaCl₂

  • Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine.
  • 40.08 g/mol + 70.9 g/mol =110.98 g/mol

The molar mass of CaCl₂ is <u>110.98 grams per mole. </u>
