When Raymond observes certain natural phenomena, he often forms ideas about their causes and effects. Suppose that Raymond surmi

ses that leaves change color in autumn due to scarcity of sunlight. In order to test whether his idea is accurate, he must first construct a falsifiable that defines a clear relationship between two variables. Raymond’s next step is to that would isolate and test the relationship between the two variables. This task can be pretty daunting because Raymond will need to identify and eliminate any variables that could confuse test results.

Answer:

The two variables involved here are sunlight and color of the leaves.

A statement is falsifiable if some observation might show it to be false. In this case, the falsifiable is:  leaves change color in autumn due to scarcity of sunlight. If anybody observes leaves with no change in color after a scarcity of sunlight, then the hypothesis is false.

Consider the following system at equilibrium:
Vika [28.1K]

Answer:

1) Rightward shift

2) Rightward shift

3) Leftward shift

4) Leftward shift

5) Leftward shift

6) Rightward shift

7) No shift

8) No shift                                                              

   

Explanation:

To evaluate each case we need to consider Le Chatelier's Principle, which states that the adding of additional reactants or products to a system will shift the equilibrium in the opposite direction, to maintain the equilibrium of the system. On the contrary, if we remove a reactant or a product in the system, the equilibrium will be shifted in the direction of the reactant or product reduced, to produce more of it (and thus maintain balance).        

Taking into account the above, let's see each statement, in the following equation:

A(aq) + B(aq)  ⇄  2C(aq)    (1)

1) Increase A. This will cause a rightward shift in equation 1 in order to consume the reactant added.

2) Increase B. Same as 1), this will cause a rightward in equation 1.

3) Increase C. This will cause a leftward shift in order to consume the excess of product in the system.  

4) Decrease A. This will produce a leftward shift to produce the reactant that is being reduced.

5) Decrease B. Same as 4), a leftward shift.

6) Decrease C. This will produce a rightward shift to produce the product that is being reduced.

7) Double A, half B. The double A will cause a rightward shift and the half B will produce a leftward shift, which results in no shift.

8) Double both B and C. Double B will produce a rightward shift and double C will produce the contrary, a leftward shift, so the final result is no shift.

               

I hope it helps you!

A mixture is made by combining 1.62 lb of salt and 5.20 lb of water.
WINSTONCH [101]

Answer:

23.8

Explanation:

Formula

weight % = weight of solute/ weight of solution x 100

weight of solution = weight of salt + weight of water

weight of solution = 1.62 lb + 5.20 lb = 6.82 lb

weight % = 1.62 / 6,82 x 100

weight % = 0.238 x 100

weight % = 23.8

Which property of chlorine explains why it is likely to form a compound with an alkali metal
Aleksandr [31]

Answer:

a. It will accept one electron to complete its outer shell.

Explanation:

Chlorine is in Group 17, so it has <em>seven valence electrons</em>, one short of a complete outer shell.

Thus, it will accept an electron from sodium to complete its outer shell.
