Answer:
Jimmy wrote two expressions that are not equivalent
Explanation:
24+6=30 while 6(4+2) equals 36 because if you distribute the 6 to 4 (which equals 24) then the 6 to 2 (which equals 12) and add 24 and 12 together, you get 36. So, 24+6 =/= 6(4+2). Hopefully this is correct!
The -1 charge means that there is one more electron than protons, so there are 85 protons
Answer:
4.88 M
Explanation:
M = number moles/Volume (L)
MM AlCl3 = 133.34 g/mol
Volume = 500 mL = 0.5 L
number moles = mass/MM = 325.4/133.34 = 2.44 moles AlCl3
M = 2.44/0.5 = 4.88 M
Moles H2O = 362 / 18.02 g/mol=20
<span>2 H2 + O2 = 2 H2O </span>
<span>moles H2 = 40.5 g / 2.016 g/mol=20 </span>
<span>the ratio between H2 and H2O is 2 : 2 so the yield is 100% </span>
<span>moles O2 required = 20 / 2 = 10 </span>
<span>mass O2 = 10 mol x 32 g/mol= 320 g</span>
Answer:
What happens when an acid is mixed with water?
Explanation:
When you mix acid with water, it's extremely important to add the acid to the water rather than the other way around. This is because acid and water react in a vigorous exothermic reaction, releasing heat, sometimes boiling the liquid. When you add water to acid, the water boils and the acid may splatter and splash.
