Water is made up of atoms bonded to form molecules, the chemical formula for water is H20, and 1 side has a positive charge, while the other has a negative one.
<h3>What is water?</h3>
Water is a fundamental molecule for life on the Earth due to its physico-chemical properties.
The water formula is H2O, which means that this molecule is composed of two atoms of Hydrogen and one atom of Oxygen.
In conclusion, Water is made up of atoms bonded to form molecules, the chemical formula for water is H20, and 1 side has a positive charge, while the other has a negative one.

Answer:
Explanation:
The formula for gravitational potential energy is the mass*gravity*height. Therefore, the greater the distance from the ground, the higher the gravitational potential energy.
Answer:
0.733 J/g °C
Explanation:
<u>Step 1 : Write formule of specific heat</u>
<u />
Q
=
mc
Δ
T
with Q = heat transfer (J)
with m = mass of the substance
with c = specific heat ⇒ depends on material and phase ( J/g °C)
Δ
T = Change in temperature
<u />
in this case :
Q = 38.5 J
<u>m = 17.5g</u>
<u>c= has to be determined</u>
<u>Δ
T = 3 (°C)</u>
<u />
<u>Step 2: Calculating specific heat</u>
⇒ via the formule Q
=
mc
Δ
T
38.5 J = 17.5g * c * 3
38.5 = 52.5 *c
c = 38.5 / 52.5
c = 0.733 J/g °C ⇒ 0.733 is reported to three significant digits due to the precision.
The specific heat of this metal is 0.733 J/g °C
2) amine is the correct answer
