Answer:
50 Meters North
Explanation:
Displacement is the distance/direction from the start point to
the ending point, regardless of which route you took from the start to the end.
So, you would simply subtract:
1,500 meters North- 1,450 meters South= 50 meters North
Answer:
I think it is mixture and of chemical reaction
Answer:-
HCl is a volatile acid. It easily evaporates at room temperature. So the concentrated HCl which is supposed to be 12 M is no longer 12 M since some of the HCl has already escaped as vapor.
Hence when a solution of 6M HCl is made from a stock of concentrated HCl by adding an equal volume of water, the concentration of the solution is only an approximate concentration since the concentration of the stock concentrated solution is also approximate.
Answer:
5.56g of FeCl2 can be produced
Explanation:
To solve this question we must find the moles of each reactant. With the moles and the chemical equation we can find limiting reactant. With limiting reactant we can find the moles of FeCl2 and its mass as follows:
<em>Moles HCl:</em>
1.5L * (0.25mol / L) = 0.375 moles HCl
<em>Moles Fe -Molar mass: 55.845g/mol-</em>
2.45g * (1mol / 55.845g) = 0.0439 moles Fe
For a complete reaction of 0.375 moles HCl are needed:
0.375 moles HCl * (1mol Fe / 2mol HCl) = 0.1875 moles Fe
As there are just 0.0439 moles Fe, <em>Fe is limiting reactant</em>
<em />
1mol of Fe produce 1 mole of FeCl2, 0.0439 moles Fe produce 0.0439 moles of FeCl2. The mass is:
<em>Mass FeCl2 -Molar mass: 126.751g/mol:</em>
0.0439 moles Fe * (126.751g / mol) =
<h3>5.56g of FeCl2 can be produced</h3>
