Answer:
the answer is true
Explanation:
it is the smallest particle in an element that takes part in a chemical reaction
According to the given reaction, 2 moles of As react with 6 moles of NaOH. Use this ratio to find how many moles of NaOH react with 492 moles of As.
It means that you need 1476 moles of NaOH to use 492 moles of As all up.
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
The balanced reaction is:
<span>2Al (s) + 3Fe(NO3)2 (aq) = 3Fe (s) + 2Al(NO3)3 (aq)
</span>
We are given the amount of <span>iron (II) nitrate solution with its purity. This will be the starting point of our calculation.
265 (.845) gram </span>iron (II) nitrate (1 mol Fe(NO3)2 / 179.85 g Fe(NO3)2) ( 3 mol Fe / 3 mol <span>Fe(NO3)2) (55.85 g Fe / 1 mol Fe) = 69.54 g Fe</span>
