physical, mathematical, and conceptual are the 3 types of models an example of a conceptual model is a model of our solar system or even a rocket a limitation of them is they are not realistic in scale but allow us see arrangements of things. mathematical models could be something like a formula graph charts ect we benefit from the visual steps however the downfall is there's lots of user error and a physical model is something like an atom model it allows to see the thing but it's physical states limits us

The burning of propane gas can be represented as a balanced chemical reaction as follows: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g) Calcula
Snezhnost [94]

Answer: 20L of H2O

Explanation:

C3H8 + 5O2 → 3CO2 + 4H2O

Recall 1mole of a gas contains 22.4L at stp

5moles of O2 contains = 5 x 22.4 = 112L

4moles of H2O contains = 4 x 22.4 = 89.6L

From the equation,

112L of O2 produced 89.6L H2O

There for 25L of O2 will produce XL of H2O i.e

XL of H2O = (25 x 89.6)/112 = 20L

The surface temperature on Venus may approach 757 K. What is this temperature in degrees Celsius?
kotykmax [81]

Explanation:

1 ) Temperature of Venus in Kelvins =  757 Kelvins

0^oC=273 Kelvins

Temperature of Venus in degrees Celsius =757-273 K=484 K

2 ) Temperature on Mercury at night = -269^oF

(T)^oC=((T)^oF-32)\times \frac{5}{9}

(T)^oC=((-269)^oF-32)\times \frac{5}{9}=167.22^oC

Temperature on Mercury at night in degree Celsius = 167.22° C
