Answer:
FALSE!!! Thermal energy can be transformed to heat.
Explanation:
Answer is: 550,021 kWh of energy is needed to heat the water
V(water) = 51 gal = 51·3,78 = 189,3 L.
ΔT(water) = 25°C.
d(water) = 1000 g/L.
m(water) = V(water) · d(water)
m(water) = 189,3 L · 1000 g/L
m(water) = 189300 g.
Q = m(water) · ΔT(water) · C(water)
Q = 189300 g · 25°C · 4,184 J/°C·g
Q = 19800780 J = 19800,78 kJ ÷ 3600 = 550,021 kWh.
It would have filtered already within the time frame of 2 to 3 hours because of the molecular injection ignited by the co2 within the strip so you would observe the UNDERSIDE OF THE PAPER and the molecular tear within it
Answer:
C. hydration number
Explanation:
When we dissolve an ionic compound (a charged species) the charges can <u>interact with the water molecule</u>. In the case of <u>cations</u> (positive charges) the negative <u>dipole</u> of water (generated in the oxygen) will interact with the positive charge at the same time the <u>anions</u> (negative charges) the positive <u>dipole</u> of water (generated in the hydrogen).
The amount of water molecules that can interact with a single ion (cation or anion) is called <u>hydration number</u>. In the example, we have a hydration number of "4" for the sodium cation.
I hope it helps!
