Answer:
it will probably flame up or explode or maybe start boiling
It will take 15 s to travel 6 cm
<h3>Further explanation</h3>
Given
distance versus time graph
Required
time travel
Solution
Caterpillar motion is a straight motion with a constant speed, so that the graph between distance and time forms a diagonal line
If we look at the graph, we can determine the time taken when the distance reaches 6 cm (y axis) by drawing a line to the diagonal line and cutting the x-axis as time, and we get 15 s
Or we can also use the formula for motion at constant speed:
d = v x t
With v at point 2,5 of 2/5 m / s, so the time taken:

Answer:
ΔH°c = - 1605.1 KJ
Explanation:
- CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
∴ ΔHf CH4(g) = - 74.6 KJ/mol
∴ ΔHf CO2(g) = - 393.5bKJ/mol
∴ ΔHfH2O(g) = - 241.82 KJ/mol
standard enthalpy of combustion (ΔH°c):
⇒ ΔH°c = (2)(ΔHf H2O) + ΔHfCO2 - ΔHfCH4
⇒ ΔH°c = (2)(- 241.82) + ( - 393.5 ) - ( - 74.6 )
⇒ ΔH°c = - 802.54 KJ/mol
⇒ ΔH°c = ( - 802.54 KJ/mol )( 2 mol CH4 )
⇒ ΔH°c = - 1605.08 KJ
