Se02 is the formula for selenium dioxide, hope this helped.
The net ionic equation is
2H+ (aq) + 2OH-(aq)→ 2H2O (l)
explanation
2HBr (aq) +Ba(OH) (aq)→ 2H2O (l) + BaBr2 (aq)
from the chemical equation above write write the ionic equation
2H +(aq) +2Br-(aq) + Ba2+ (aq) +2OH-(aq)→ 2H2O(l) +Ba2+(aq) +2Br-
cancel the spectator ions in both side( Ba2+ and 2Br-)
the net ionic equation is therefore
2H+ (aq) + 2OH-(aq)→ 2H2O (l)
<em>Answer </em>
<em>no</em><em>. </em><em>of</em><em> </em><em>moles</em><em> </em><em>=</em>
<em></em>
so, <em>mass</em><em> </em><em>(</em><em>g</em><em>)</em><em>=</em><em> </em><em>no</em><em>. </em><em>of</em><em> </em><em>mol</em><em>es</em><em> </em><em>×</em><em> </em><em>molecular </em><em>wight </em>
Explanation:
Li molecular wight equal to 6.941
mass (g)=3.29×104 <em>mol</em><em> </em><em>×</em><em>6</em><em>.</em><em>9</em><em>4</em><em>1</em><em> </em><em>=</em><em>2</em><em>3</em><em>7</em><em>4</em><em>.</em><em>9</em><em>3</em><em>g</em><em> </em><em>of</em><em> </em><em>lithium </em>
Answer : The amount of in kilojoules released is, -5.53 kJ
Explanation :
Formula used :
where,
q = heat released = ?
c = specific heat of ethanol =
m = mass of ethanol = 23.4 g
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
Therefore, the amount of in kilojoules released is, -5.53 kJ
Answer:
Explanation:
Here are the ones I'm certain of.
10, Transfer of electrons occurs in NaCl. That's another way of saying that the bond is ionic.
12. What is a polar molecule. The two hydrogens are + and the Oxygen is minus.
9. Contains just one sigma bond. H2 is made up of only 1 bond type. I'd pick this, but It's not certain.
=============
The one I'm uncertain of is 11. I'd pick E but it is a pure guess. The only other choice is CO2 but I don't think CO2 is that way. You'll have to enter the answers to find out which is which.
