Answer: 2.796 grams
Explanation:
According to stoichiometry:
1 mole of 
reacts with 1 mole of 
0.012 moles of will react with=
of
Thus is the limiting reagent as it limits the formation of product. is the excess reagent as (0.018-0.012)=0.006 moles are left unused.
1 mole of produces 1 mole of 
0.012 moles of will produce= of
Mass of 
Thus 2.796 grams of are produced.
Answer:
2.1 M
Explanation:
The dilution equation is 
.
= the molarity of the sock solution
= the volume of the sock solution
= the molarity of the diluted solution
= the volume of the diluted solution
The stock solution would be what is doing the diluting, so "175 mL of a 3.00 M solution". So = 3.00 M. Then: Converting 175 mL to liters: 
(This is )
And converting 250 mL KCl to liters: 
(This will be )
Then, we plug in our given into the dilution equation, resulting in:
(divide both sides by 0.250 L, in order to get by itself)
So, the molarity of 250 mL KCl made by diluting 175 mL of a 3.0 M solution would be 2.1 M (mol/L).
Hopefully this helped you understand the topic a little bit better. I just finished molarity and dilutions in Chemistry last week. Good luck!
Answer:
I think its a double reaction
Explanation:
B.)C=C is the right answer.
because h<span>aving more double bonds than single bonds decreases the melting point and, hence, the fluidity of the substance this is why butter is a solid but canola oil is a liquid at room temperature.</span>
In this case, the reference forms of the constituent elements are O 2<span>(g) and graphite for carbon. </span>Using<span> the values in the above table of </span>standard enthalpies of formation, calculate the ΔHreactiono<span> for the </span>formation<span> of NO</span>2(g). The relevantstandard enthalpy<span> of </span>formation<span> values from Table 1 are: O</span>2<span>(g): 0 kJ/mol.
</span>CO(g) + H2O(g) -> CO2(g) + H2(g)=https://www.dropbox.com/s/8imewsdgt9t6m47/Screenshot%202016-10-18%2008.10.36.png?dl=0
