It is limited by the depth divers and equipment can go.
Answer:
42.3moles
Explanation:
The chemical equation given in this question is as follows:
H2 + O2 → H2O
However, this equation is unbalanced, the balanced chemical equation is as follows:
2H2 + O2 → 2H2O
This equation shows that;
2 moles of hydrogen gas (H2) will produce 2 moles of water (H2O)
Hence, If 42.3 moles of water (H2O) are produced, 42.3 × 2/2
= 42.3moles of hydrogen was reacted.
Answer: A
Explanation: frying an egg
Answer: hope it help
Explanation:
1. I assume that it is possible to create the most beneficial consequences in rural zones where agricultural production is concentrated in the region as solutions are placed in place to reduce the human effect on nature. That is because agriculture is a practice that has a huge effect so it is important to protect the climate and nature so that farming can continue.
2. The first suggestion I make to my group is that limited waste disposal should be used. This will encourage any recycled material to have no association with products that would stop recycling. When the love is recycled,
Answer:
At the second equivalent point 200 mL of NaOH is required.
Explanation:
at the first equivalent point:
H2A + OH- = HA- + H2O
initial mmoles y*100 y*100 - -
final mmoles 0 0 y*100 y*100
at the second equivalent point:
HA- + OH- = A2- + H2O
initial mmoles y*100 y*100 - -
final mmoles - - y*100 y*100
at the second equivalent point we have that y*100 mmoles of NaOH or 100 mL of NaOH ir required, thus:
at the second equivalent point 200 mL of NaOH is required.
