Answer:
Mechanical energy
Kinetic energy
Explanation:
The mechanical energy is the sum of the kinetic and potential energy of the particles that make up the baseball.
Mechanical energy is made up of kinetic energy and potential energy. When the baseball is in motion, the particles make use of the kinetic energy, also known as motion energy and when the ball is not in motion the particles make use of the potential energy, also known as stored energy.
The reaction represents the law of conservation of mass (a balanced chemical equation :
2NaN₃ → 2Na + 3N₂
<h3>Further explanation
</h3>
Conservation of mass applies to a closed system, where the masses before and after the reaction are the same, so balanced chemical equations show that mass is conserved in chemical reactions.
So we just have to look at the amount of each type of element present in the reactants and products must be the same
1. Hg + O₂ → HgO
not balanced, because element O not equal(2 in left, 1 in right)
2. 2NaN₃ → 2Na + 3N₂
balanced, because element in reactant and product are the same
Na, left = 2, right=2
N, left =2x3=6, right=3x2=6
3. C+O → CO₂
not balanced, because element O not equal(1 in left, 2 in right)
4. CH₄ + O₂ → CO₂ +H₂O
not balanced, because element O and H not equal
Can u send a picture so I know wat ur talking about
For every 3 Fe there is only 1 Fe3O4 producing.
So, ratio would be: Fe3O4 / Fe = 1 / 3
In short, Your Answer would be: 1 : 3
Hope this helps!
Answer:
C. METHANE
Explanation:
The blue color of both the ice giants can be contributed to the presence of methane in their upper atmospheres. Methane absorbs most of the red light incident on the planets which makes them appear blue in color.
