The answer to this question would be: <span>its concentration is half that of the cl− ion.
When CaCl2 molecule dissolved, it will split into one Ca2+ ion and two Cl- ion. That means for every 1 CaCl2 there will be 3 ions formed. In this case, the amount of Ca2+ should be half of Cl- ion. An element with higher valence tends to have less atom in a molecule than an element with lesser valence </span>electron.
C2H6 (g) + O2 (g). --> CO2(g)+H2O (g)
2C2H6 (g) + 7O2 (g). --> 4CO2(g)+6H2O (g)
(8.45 x 10^23)/(6.022x10^23) = 1.403 moles H2O
1.403 moles H2O x (4molCO2/6molH2O)= .935 moles CO2
.935 moles CO2 x (6.022 x10^23)= 5.63 x 10^23 molecules CO2
Chromium exhibits a wide range of possible oxidation states, where the +3 state is the most stable energetically. The +3 and +6 states are the most commonly observed in chromium compounds, whereas the +1, +4 and +5 states are rare.
Atomic mass units is a unit of measurement of mass, same with grams. Therefore, we can convert the two measurements back and forth using a conversion factor. For every 1 amu, there are 1.66054×10⁻²⁴ grams. The solution is as follows:
(1.674×10⁻²⁴ g)(1 amu/1.66054×10⁻²⁴ g) = <em>1</em><em>.008 amu of neutrons</em>
Answer:
I think emi should put it in a metal container and put it in the direction of the sun cause this will help produce heat as the sun shines on the metal container
