Answer:
30 moles of water will produced.
Explanation:
Given data:
Number of moles of O₂ react = 15 mol
Number of moles of water formed = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Now we will compare the moles of water with oxygen.
O₂ : H₂O
1 : 2
15 : 2×15 = 30 mol
30 moles of water will produced.
No, It can't be chemical because it has something to do with being mechanical, an example of a chemical change would be some thing like metal rusting or wood turning to ash after being burned.
Answer:
magnetite
Explanation:
proportion of iron in haematite = 3.5/5 x 100% = 70%
proportion of iron in magnetite = 7.2/10 x 100% = 72%
The average rate of a reaction is a good approximation of an instantaneous rate when the concentration is measured during relatively brief time intervals.
At any point during such a little period, the average rate will be extremely near to the instantaneous rate. The average rate will differ from the instantaneous rates inside the period more when time intervals are longer.
The concentration change during a chosen time period is the average rate. When you take the measurements makes a difference.
The rate at a specific moment is known as the instantaneous rate. Finding the slope of the tangent to the concentration vs. time curve at that point yields the answer.

The importance of the Galapagos to Darwin theory is chances Darwin discovered several species of finches that varied from island to island .
A big part of reason it is so famous is because of Darwin finches.
which are 12 <span>species ,also the Darwin theory is only gradually accepted because people don't believe in them today</span>
