The answer would be
A) Increases; left to right.
This is the answer because if you notice it says period and a period in the periodic table is a horizontal row that goes from left to right.
Answer:
0.000025mol/L
Explanation:
pH = -log[H3O+]
Here, we know that pH = 4.6 while the concentration of [H30+] is what we are to find. This can be obtained as follows:
4.6 = -log[H30+]
[H3O+] = -Antilog(4.6)
= 0.000025mol/L
<h3>
Answer:</h3>
H₂O
<h3>
Explanation:</h3>
The additional product that balances the reaction is water (H₂O).
- Therefore, the complete balanced equation for the reaction is;
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + H₂O(l)
- Balancing a chemical equation ensures that the law of conservation of mass is obeyed by the reaction.
- The reaction is an example of a neutralization reaction where an acid, H₂SO₄, reacts with a base, NaOH to form a salt and water.
- In this case the salt formed is sodium sulfate (Na₂SO₄)
The constant use of water flow throwout nature and the way that we use it now isint good and most likly we will be out of water by the year 2055
The net ionic equation of the reaction could be determined by cancelling out the like ions between both sides of the reaction. These ions are called spectator ions. They are called as such because they do not actively participate in the reaction. The spectator ions are Na+ and Cl-. When you cancel those, the equation would become letter D.
