Answer:
Lateral
Explanation:
Is the opposite side of the midline
The two control bases would be water and salt.
<u><em>Answer</em></u>
<u><em>Explanation</em></u>
- In periodic table, the elements have almost same properties are present in the same group. As Mg and Sr are present in group II-A, so both behave most likely to each other due to having same valence shell electrons as well.
- Si and Sn are present in group IV-A which have same behavior but different one from Mg due to different groups.
- S is present in group VI-A which show different properties from all others one especially from Mg.
Answer:
Because of the revolution of the moon about the earth.
Explanation:
The moon is the natural satellite of the earth; which rotates about its axes and orbits around the earth. As the moon orbits the earth with respect to time, it would complete a revolution in 27.3 days.
During revolution, different phases of the moon can be observed by someone on the earth. This is due to its location at different time during the process. Therefore, Jorge was able to see different phases of the moon because of its revolution about the earth.
The balanced equation :
4Fe + 3O₂⇒ 2Fe₂O₃
<h3>Further explanation</h3>
Given
Rust reaction
Required
Balanced equation
Solution
Reaction
Fe + O₂⇒ 2Fe₂O₃
For a simple equation where one of the reaction coefficients is known, we can immediately add the corresponding coefficient using the principle that the number of atoms of <em>the components in the reactants and products is the same.
</em>
In the above reaction :
Fe, left=1, right = 4, so coefficient in the left=4
O, left=2, right = 6, so coefficient in the left=3
