Answer:
Option D:
evaporation from lakes and rivers
Explanation:
The water cycle is a natural cycle that shows how water moves and circulates within a natural environment. Water usually moves between the hydrosphere and the atmosphere through evaporation and condensation.
When water evaporates from the hydrosphere (the water bodies), it goes up into the atmosphere where it cools to become clouds. As more water evaporates, the clouds formed increase in mass. Once the clouds are too heavy to be held up in the sky, they fall down as precipitation (rain, snow, hail) into the water bodies and surrounding land below.
Balanced:
2NaOH + CO2 → Na₂CO₃ + H₂O
Explanation:
To balance an equation, the amount of atoms on each side must be <u>equal.</u>
Atom Count on Reactant Side:
Atom Count On Product Side:
As you see, to simply balance the equation, put the 2 in order for the atom count on the reactant side to be equal to the product side. The 2 will add one more of each atom so that its the same as the product side.
Answer:
1.58L
Explanation:
Given parameters:
Initial volume = 1.2L
Initial temperature = 28.5°C = 28.5 + 273 = 301.5K
Final temperature = 125°C = 125 + 273 = 398K
Unknown:
New volume = ?
Solution:
Volume and temperature relationship is resolved using the Charles's law.
The law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the the pressure is constant".
So;
=
V1 is the initial volume
T1 is the initial temperature
V2 is the new volume
T2 is the new temperature
=
301.5V2 = 477.6
V2 = 1.58L
The human eye see objects through light reflects off
objects, enters the eyes, and is detected by the optic nerve in the retina. The
answer is letter B. The rest of the
