Answer: 19.25 gallons

Explanation: 1 ml = 0.0011 quart

Given:  4 quarts = 1 gallon

Thus if 1 ml is equal to 0.0011 quart

70000 ml  is equal to =\frac{0.0011}{1}\times 70000=77quart

Now if 4 quarts is equal to 1 gallon.

77 quarts is is equal to=\frac{1}{4}\times 77=19.25gallons

75000mL (1 liter/1000 mL)(1 gallon/3.785 liters)  

= [75000*1*1] / [1000*3.785] gallons  = 19.815 gallons

Why are red dwarfs not able to fuse helium to heavier elements?
ohaa [14]
Fusing helium into heavier elements requires extreme pressure and temperature. However red dwarfs' gravity is simply not enough to bring helium atom close enough to each other for fusion to occur. Therefore, red dwarfs not able to fuse helium to heavier elements.☺

A solution was prepared by dissolving 2.2 g of an unknown solute in 16.7 g of CCl4. A thermal analysis was performed for this so
laila [671]

Answer:

Molar mass of unknown solute is 679 g/mol

Explanation:

Let us assume that the solute is a non-electrolyte.

For a solution with non-electrolyte solute remains dissolved in it -

Depression in freezing point of solution, \Delta T_{f}=K_{f}.m

where, m is molality of solute in solution and K_{f} is cryogenoscopic constant of solvent.

Here \Delta T_{f}=(-22.9^{0}\textrm{C})-(-28.7^{0}\textrm{C})=5.8^{0}\textrm{C}

If molar mass of unknown solute is M g/mol then-

                 m=\frac{\frac{2.2}{M}}{0.0167}mol/kg

So, 5.8^{0}\textrm{C}=29.9^{0}\textrm{C}/(mol/kg)\times \frac{\frac{2.2g}{M}}{0.0167}mol/kg

so, M = 679 g/mol

When a capacitor has a potential difference between the plates it is said to be ? . one plate has an excess of electrons and one
Ede4ka [16]

When a capacitor has a potential difference between the plates it is said to be Constant.

Both plates have different charge which signifies that one has higher potential than the other.

Therefore, when we join them in parallel, charge will flow from higher to lower. and it continued to flow until equilibrium (the entire process took only a few seconds), indicating that the potential remains constant.
