Answer:
+125.4 KJmol-1
Explanation:
∆H C4H10(g) = -2877.6kJ/mol
∆H C(s)=-393.5kJ/mol
∆H H2(g) = -285.8
∆H reaction= ∆Hproducts - ∆H reactants
∆H reaction= (-2877.6kJ/mol) - [4(-393.5kJ/mol) +5(-285.8)]
∆H reaction= +125.4 KJmol-1
Answer: 19.71 feet
Explanation:
Given: Speed of Charlotte =58.6 mi/h
Since 1 hour = 3600 seconds
and 1 mile = 5280 feet
So, Speed of Charlotte =
mi/ sec
She looks down at her phone and takes her eyes off the road for 4.36 s.
Since , Distance = 
So, Distance = 
Hence, Charlotte traveled 19.71 feet during this time.
Answer:
false,soil damage and nutrient loss can be a major problem so it can not gain nutrients quickly
Answer:
Hexane.
Explanation:
Hello!
In this case, since the general reaction of the compound C4H14 with chlorine is:

Which stands for a substitution chemical reaction in which one chlorine is able to replace one hydrogen and therefore hydrogen chloride gives off; we infer that the initial compound, C4H14, shows off the
formula characteristic of alkanes; in such a way, as it has six carbon atoms, we infer it is hexane.
Best regards!
