Explanation:
The mass of octane in the sample of gasoline is 0.02851 * 482.6 = 13.759 g of octane.
The balanced equation is:
2C8H18(l) + 25O2(g) ----> 16CO2(g) + 18H2O(g)
From the equation, using atomic masses:
228.29 g of octane forms 704 g of CO2 and 324.3 g of H2O
So the mass of CO2 formed from the combustion of 13.759 g of octane = (704 * 13.759) / 228.29
= 42.43 g of CO2.
Amount of water = 324.3 * 13.759) / 228.29
= 19.55 g of H2O.
Answer:
The correct answer is by adding surface roughness to increase friction.
Explanation:
Land plants need to be tall and the vascular tissues are what provide rigidity to the plant’s cells.
Land plants need to photosynthesize and the vascular tissues is where this process occurs.
Land plants don’t really need these structures as they can absorb water from the air through their leaves.
A. the plant in closet will die.
B. plants only need soil to grow.
c. plants only need water to grow.
d.it does not matter where he puts the plant.
