A cube of zinc and a cube of silver have the same volume. The mass of the zinc is 55lbs (pounds). What is the mass of the silver
Dovator [93]

Answer:

Explanation:

Convert 55lbs to kg

(55 lb)*(453.6 g/lb) = 24948 g or 249.48 kg

Density of zinc = 7140 kg/m^3

Find the volume occupied by 249.48 kg:

  (249.48 kg)/(7140 kg/m^3) = 0.055 m^3

Density of silver = 10,490 kg/m^3

Mass of Ag in 0.055m^3:

  (0.055m^3)*(10,490 kg/m^3) = 577 kg

Which is warmer 10c or 30f
OleMash [197]

Answer:

your answer is 30f

Explanation:

The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.

2Na+S→Na2S
Sedbober [7]

Answer:

2.0 moles S

Explanation:

To find the number of moles of S, you need to convert the moles Na to moles S via the mole-to-mole ratio. This ratio is represented by the coefficients in the balanced equation. Because you wish to find moles S, you want to put this number in the numerator. Because you want to eliminate the moles Na, this number should be in the denominator.

2 Na + 1 S ---> Na₂S

4.0 moles Na             1 mole S
----------------------  x  ---------------------  =  2.0 moles S
                                 2 moles Na

Why does increasing the number of trials increase confidence in the results of the experiment?
valkas [14]
<span>It rises confidence for the reason that the more times you conduct the similar experiment over and over should either demonstrate your hypothesis right and wrong and remove any random incidences that might touch your results. Meaning it permits to have a more accurate measure or conclusion.</span>
