<span>According to the question-
1 mol C3H8O = 60.096 g C3H8O
2 mol C3H8O = 9 mol O2
1 mol O2 = 31.998 g O2
[(3.00 g C3H8O)/1][(1 mol C3H8O)/(60.096)][(9 mol O2)/(2 mol C3H8O)][(32.998 g O2)/(1 mol O2)] = 7.1880435 g O2
Since 7.1880435 g of O2 is needed, and 7.38 g of O2 is available, 0.199565 g of O2 will be left over and oxygen is present in excess.
Next, we need to convert 0.199565 g of O2 into moles of O2:
[(0.199565 g O2)/1][(1 mol O2)/(31.998 g O2)] = 0.005999 mol O2, or 0.006 mol O2</span>
Answer:
1.04 mol
Explanation:
CO₂ is produced in a closed 100 L vessel according to the following equation.
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
At equilibrium, the pressure of carbon dioxide remains constant at 1.00 atm.
First, we need to conver the temperature to the absolute scale (Kelvin scale) using the following expression.
K = °C + 273.15
K = 898°C + 273.15
K = 1171 K
Now, we can find the moles of carbon dioxide using the ideal gas equation.
Answer:
synthesis reaction
The chemical reaction 2H2+O2→2H2O 2 H 2 + O 2 → 2 H 2 O is classified as a synthesis reaction
Answer:
A. The lens spreads light.
Explanation:
The convex lens will converge the light that passes through it. The direction of light will be bend to be closer to the middle point. This is the lens used for the eyeglass that treat people with hypermetropia. That is why the convex lens also called a converging lens or a plus lens. The strength of the convex lens depends on its focal length, index of the material used, and the radius of curvature.
