Answer:

Option C, spontaneous or nonspontaneous depending upon the temperature of the surroundings and pressure

Explanation:

AT room temperature, the temperature is favorable for ice to melt and hence melting of ice at room temperature is spontaneous but when the temperature is below the melting point and even then the ice melts then it is called non spontaneous. In this case, the enthalpy and entropy together create a positive change in the free energy for melting.

Hence, option C is correct

Muiltplying 2.5 x 10^10 by 3.5 x 10^-7
andrey2020 [161]

<u>Answer: </u>

The value of \left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right) is 8750

<u>Solution: </u>

\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)

\Rightarrow\left(2.5 \times 10^{10} \times 3.5 \times 10^{-7}\right)

\Rightarrow\left(2.5 \times 3.5 \times\left(10^{10} \times 10^{-7}\right)\right)

\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)

\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)

\Rightarrow(2.5 \times 3.5) \times 10^{3}

\Rightarrow 8.75 \times 10^{3}

\Rightarrow 8.75 \times 1000=8750

What atom or ion make up 2 protons and 10 electrons?
Gala2k [10]
The atom that is made up of two protons is He. The number of neutrons is also two. The number of electrons matters in the charge. So to make 10 electrons, we add 8 more. hence, 4/2 He 8-.

Which unit conversion allows you to convert 21.0 gallons into milliliters?
Romashka-Z-Leto [24]

79470.2mL

Explanation:

Given:

  Volume = 21gallons

  problem, convert to milliliters;

   

  gallons to milliliters

 1 liter = 1.057 quarts

1 gallon = 4 quarts

we can simply solve this by establishing and using a conversion factor of 1 ;

     

   1 gallon = 4 quarts

   1.057 quarts = 1 liter

   0.001L = 1mL

21gallons x \frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}  = 79470.2mL

we say;

From; \frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}

1gallon = 3784.2mL
