Answer:

Zoology is the part of biology relating to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct.

In other words, is the study of animals.

Astronomy is the study of the physical universe beyond the Earth's atmosphere including the process of mapping locations and properties of the matter and radiation in the universe.

In other words, is the study of the physical universe beyond the Earth's atmosphere.

Hope it helps.

Brainliest please.

Zinc reacts with hydrochloric acid according to the reaction equation Zn ( s ) + 2 HCl ( aq ) ⟶ ZnCl 2 ( aq ) + H 2 ( g ) How ma
REY [17]

Answer:

34.7mL

Explanation:

First we have to convert our grams of Zinc to moles of zinc so we can relate that number to our chemical equation.

So: 6.25g Zn x (1 mol / 65.39 g) = 0.0956 mol Zn

All that was done above was multiplying the grams of zinc by the reciprocal of zincs molar mass so our units would cancel and leave us with moles of zinc.

So now we need to go to HCl!

To do that we multiply by the molar coefficients in the chemical equation:

\frac{0.0956g Zn}{1 } (\frac{2 mol HCl}{1molZn})

This leaves us with 2(0.0956) = 0.1912 mol HCl

Now we use the relationship M= moles / volume , to calculate our volume

Rearranging we get that V = moles / M

Now we plug in: V = 0.1912 mol HCl / 5.50 M HCl

V= 0.0347 L

To change this to milliliters we multiply by 1000 so:

34.7 mL

A flashlight battery is hooked to a toy motor, and then the battery and the connections are sprayed with a water-proof coating.
denis-greek [22]

Explanation:

Formula to calculate work done by motor is as follows.

         Work done by motor = mass \times g \times height

where,   g = gravitational constant = 10 m/s^{2}

Therefore, work done by motor is as follows.

 Work done by motor = 1.00 kg \times 10 m/s^{2} \times 10.0 m  

                                  = 100.0 J

Now, heat lost by water will be calculated as follows.

            q = mC \times \Delta T

                = g \times 4.184 J/g^{o}C \times 0.024^{o}C

                = 10.0 J

Hence, heat gained by motor = heat lost by water

As, heat gained by motor = 10.0 J

So, change in energy = heat gained - work done

Therefore, change in energy will be calculated as follows.  

   Change in energy = heat gained - work done

                                  = (10.0 J) - (100.0 J)

                                   = -90.0 J

Thus, we can conclude that change in the energy of the battery contents is -90.0 J.
