How many grams of heptane are needed to completely react with 106 g of O2?

Answers

Answer:

21.9g

Explanation:

The balanced reaction for the combustion of heptane is;

C7H16 + 11 O2 ------> 7 CO2 + 8 H2O

from the balanced reaction,

1 mole of heptane = 11 moles of O2

converting to mass

100g of Heptane = 484g of O2

xg of Heptane = 106g of O2

x = 106×100/484

x = 21.9g

Therefore, 21.9g of heptane is needed to completely react with 106 g of O2

A 7.28 g sample of chromium metal was heated to produce chromium oxide. The weight of the compound was 10.63 g. What is the percent chromium in this compound?

Answers

Answer:

68.48%

Explanation:

The percent mass of an element in a compound tells us about the amount of such element contributed to the total compound.

In this case, 7.28 g sample of chromium metal was heated to produce chromium oxide with weight of 10.63 g. The percent mass of chromium in chromium oxide can be calculated by using the formula:

%mass of Cr = mass of Cr/mass of Chromium oxide × 100%

%mass of Cr = 7.28/10.63 × 100

%mass of Cr = 0.6848 × 100

%mass of Cr = 68.48%

Why do we get hot when we exercise?

Answers

It’s your body’s way of regulating your core temperature, preventing you from overheating. Your muscles heat up as they expend energy during exertion. When this happens, your skin begins to sweat, causing your body to cool down. The spike in your body heat also alerts your brain to ensure your body remains at the normal core temperature of 98.6 degrees Fahrenheit (or 37 degrees Celsius).
While exercising the body begins to warm up. When the body begins to warm up our muscles convert stored energy into heat energy, making our bodies become warmer. As the body heats up further the brains thermostat ensures that you remain close to the normal core temperature.

Which event is fast change that occurs as a result of plate tectonics?
A. Hurricane
B. Volcanic eruption
C. Formation of an ocean basin
D. Convection current

Answers

Answer: B. Volcanic eruption

Explanation:

A volcano is firmed when molten rocks is formed to the surface of the Earth. Volcanoes release molten rocks, ash, and gases to the Earth's surface.

Volcanoes are agents of change as the eruptions lead to the formation of new landforms and also destroy several things that they come in contact with.

Volcanic eruptions also occurs due to plate tectonics. Other events that happen due to plate tectonics also include earthquakes, and tsunamis.

In the reaction of: ????2O4 (g) ⇌ 2????O2(g) If the equilibrium constant is Kc = 0.513 and the initial concentration of ????2O4 = 0.0500 ????. What are the equilibrium concentrations of ????2O4 and ????O2 under these conditions?

Answers

Answer:

[N₂O₄] = 0.00411 M

[NO₂] = 0.0918 M

Explanation:

In the reaction of: N₂O₄(g) ⇌ 2 NO₂(g) If the equilibrium constant is Kc = 0.513 and the initial concentration of N₂O₄ = 0.0500 M. What are the equilibrium concentrations of N₂O₄ and NO₂ under these conditions?

Step 1: Given data

Initial concentration of N₂O₄: 0.0500 M

Equilibrium constant (Kc): 0.513

Step 2: Make an ICE chart

        N₂O₄(g) ⇌ 2 NO₂(g)

I        0.0500           0

C           -x              +2x

E      0.0500-x        2x

Step 3: Find the value of "x"

The equilibrium constant is:

Kc = [NO₂]² / [N₂O₄]

0.513 = (2x)² / (0.0500-x)

4x² + 0.513 x -0.02565

We solve for x and we get x₁ = 0.0458942 and x₂ = −0.558894 (neglected).

Step 4: Calculate the concentrations at equilibrium

[N₂O₄] = 0.0500-x = 0.00411 M

[NO₂] = 2x = 0.0918 M
