Using the reactivity series shown in the handbook, tell whether the following reactions

1 answer:

6 0

The possibility of metals replacing each other is dependent on the relative positions of the metals in the activity series.

The activity series is an arrangement of elements in order of decreasing reactivity. The elements that are higher in the series can displace the elements that are lower in the series.

Before we make a decision in each case, we must consider what metal is lower or higher in the series;

Between Na and K, Na is lower in the series so the answer is no
Between Co and Cu, Co is higher than Cu in the series so the answer is yes
Since Zn and Zn^2+ are just a specie and its ion, the answer is no.
Since Ba is higher than Ni, Ni can not replace Ba so the answer is no

Consider two gases, A and B, are in a container at room temperature.

The rate of reaction would increase because as pressure increases the molecules are more likely to bump into each other leading to a more likely hood of the molecules colliding properly to react leading to an increase in the reaction rate of the substance.

PLZ HELP!!

A and B are experiencing winter. The picture which isn't available here in this question is attached below.

Option C.

<h3><u>Explanation:</u></h3>

The earth is tilt by an angle of 23.2° to the vertical plane. This makes the seasonal variation of earth, because in some time of the year, the northern hemisphere faces the sun directly, experiencing summer and then southern hemisphere is away from summer experiencing winter and vice versa. The summer occurs when the place directly faces the sun. And the winter happens when the place obliquely faces the sun or doesn't face the sun at all.

Here in this diagram, we can see that the points A and B are the north pole and the part in northern hemisphere respectively which aren't facing the sun directly, whereas C and D are facing the sun. Thus the southern hemisphere is experiencing summer and the northern hemisphere the winter.

The density of solid Cr is 7.15 g/cm3. How many atoms are present per cubic centimeter of Cr?

Masja [62]

To calculate the number of atoms of Cr, we first find the number of moles per unit of cubic centimeter of Cr. Then, use avogadros number for the number of atoms. Calculations are as follows:

1 cm^3 (7.15 g/cm^3) (1 mol / 51.996 g Cr) = 0.14 mol Cr

0.14 mol Cr ( 6.022 x 10^23 atoms Cr / 1 mol Cr ) = 8.28 x 10^22 atoms Cr

How many federal agencies are responsible for managing land resources in the United States?

dimulka [17.4K]

The answer would be 4.

The agencies are:

Department of Agriculture's Forest Service (AFS)

Department of the Interior's Bureau of Land Management (BLM)

Fish and Wildlife Service (FWS)

National Park Service (NPS)

These four agencies cover around 95% of the land and are the only federal agencies.

I learned about these agencies in school.
