The reaction is:
Cl2 + 2 KBr --> 2 KCl + Br2
Moles of KCl is
n = m /M = 12 /74 = 0.16 mol
As, twice the moles of KCl is producing from 1 mol of chlorine
mole of Cl2 = 0.16 /2 = 0.08 mol
Mass of Cl2
m /70 = 0.08 = 5.6 g
Hence, 5.6 g mol Cl2 consumed to produce KCl
The answer is 4 Newton
force = mass x acceleration
F= 2 kg x 2.0 <span>m<span>s2</span></span>
= 4 Newton
Two unstable elements that will react to almost anything
<u><em>Answer:</em></u>
- The correct option is B. The nonpolar substance has a lower boiling point than the polar substance.
<u><em>Explanation: </em></u>
- Substances with hydrogen bonding, an intermolecular force, will have much higher boiling points than those that have ordinary dipole-dipole intramolecular forces. Non-polar molecules have lower boiling points, because they are held together by the weak van der Waals forces.
<em><u>Note</u></em>
- However, if size of non polar increases, then its boiling point increases due to increases in van der walls forces with large size.
Answer:
$96.8
Explanation:
divide 847 by 28 because each gallon gets the car 28 miles and there's 847 miles in total and you get 30.25 and you multiple that by the cost so it be 30.25×3.20=$96.8
