Mass of Iron (Fe): 55.845Mass of Bromine (Br): 79.904
You need to multiply the mass of Br by 3 because there are 3 Bromine atoms.
(79.904)(3)+ 55.845= 239.712+55.845 = 295.557 g/mol
Answer:
I hope this will help you....and please mark me as Brilliant
Explanation:
1 moles N2 you can produce 2 moles of NH3, (see equation)
5 mol N2 gives 10 mole NH3
molar mass of NH3 = 17.03 g/mole
10 moles NH3 is 10 * 17.03 gram = 170.3 gram NH3.
Balanced equation:
N2(g) + 3 H2(g) → 2 NH3(g)
C. 4 decorated cupcakes.
Because 12 divided by 3 = 4, so you can have 4 cupcakes each with 3 cherries
<u>Answer:</u> 0.943 M of potassium hydroxide solution is required.
<u>Explanation:</u>
A neutralization reaction is defined as the reaction in which an acid reacts with a base to form a salt and water molecule.
To calculate the molarity of potassium hydroxide, the equation used is:
........(1)
where,
are the n-factor, molarity and volume of acid that is
are the n-factor, molarity and volume of the base that is KOH
We are given:
Putting values in equation 1, we get:
Hence, 0.943 M of potassium hydroxide solution is required.
In a redox reaction electrons are lost and gained in equal numbers. The species that is oxidized gives electrons to the species that is reduced. I hope this helps. Let me know if anything is unclear.
