Answer:
Option C. +150KJ
Explanation:
Data obtained from the question include:
Heat of reactant (Hr) = 200KJ
Heat of product (Hp) = 350KJ
Change in enthalphy (ΔH) =..?
The enthalphy of the reaction can be obtained as follow:
Change in enthalphy (ΔH) = Heat of reactant (Hp) – Heat of reactant (Hr)
ΔH = Hp – Hr
ΔH = 350 – 200
ΔH = +150KJ
Therefore, the enthalphy for the reaction above is +150KJ
Answer:
48 mph
Explanation:
total time= 19/12 hr
distence- 76 miles
speed- D/T=76/19/12
which is 48mph

Answer:

Explanation:
Given that,
A typical coffee mug holds about 355,000 microliters of liquid.

Also, 1 L = 0.001 kL

So, a typical coffee mug holds about
or
of liquid.
We need to convert it into Scientific notation.
We will shift 4 zeros to right. As a result,

So, the mug will hold
of liquid.
