Answer:
Why hydrogen is the only non-metal elements which loses electron to form positive ions ? ... When hydrogen bonded with most electronegative element then it forms a positive ions but when it bonded with less electronegative element then it forms a negative ion.
Answer: The value of 
is 1118 .
Explanation:
To calculate the number of moles, we use the equation:
The balanced chemical reaction is:
Given :
Energy released when 0.288 mole of 
is reacted = 161 kJ
Thus Energy released when 2 moles of is reacted = 
Thus the value of is 1118.
I think the correct answer from the choices listed above is option C. The statement that best explains why a crystal is incompressible would be that there is little, if any, space left between its adjacent molecules. Hope this answers the question. Have a nice day.
The mass of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride is 15.26 g.
The balanced chemical reaction is :
<em> 2Na + Cl₂ → 2NaCl</em>
<em />
Given data :
Mass of sodium = 10.0 g
Number of moles of Na -
Number of moles = <u> Given mass </u>
Molar mass
Number of moles = <u> 10.0 g</u> = 0.43 mol
23 g
Comparing moles of Na and Cl₂ from the balanced chemical equation,
Na : Cl₂
2 : 1
0.43 : <u> 1 </u> x 0.43 = 0.215 mol
2
Mass of chlorine gas :
(molar mass of chlorine = 71 g)
Mass of chlorine = number of moles x molar mass
Mass = 0.215 mol x 71 g/mol
= 15.26 g

Answer:
<em>Rate</em> = k * [C₄H₆]²
Explanation:
It is possible to write the reaction as:
The differential rate law for a simple second order reaction of the type 2A → B is:
With the above information in mind, the rate law for the reaction of butadiene would be:
- <em>Rate</em> = k * [C₄H₆]²
