So the number of moles = 0.06 moles of 4X12-2 moles.
Answer:
solar energy received at the Earth's closest and farthest locations from the sun
Explanation:
The largest effect on climate is due to changes in received solar radiation. Changes in gravity or magnetic field have not been shown to have any significant effect on climate. Day/night differences are due to the tilt of the earth's axis, and have nothing to do with earth's orbit eccentricity.
The more circular the Earth's orbit, the less the difference in solar energy received at the Earth's closest and farthest locations from the sun.
Answer: How The World Works
Explanation: Our world is made out of atoms, molecules and ions. Their behavior determines the properties of the substances we encounter in our daily lives: their structure, color, smell, and the way they interact with each other.
Answer:
118.776 mmHg
Explanation:
The equation of the reaction is;
C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H20(g)
Now the mole ratio according to the balanced reaction equation is;
1 : 6.5 : 4 : 5
Hence, the total number of moles present = 1 + 6.5 + 4 + 5 = 16.5 moles
Mole fraction of water vapour = 5/16.5 = 0.303
We also know that;
Partial pressure= mole fraction * total pressure
Partial pressure of H20(g) = 0.303 * 392 mmHg = 118.776 mmHg
Answer:
To test the accuracy of a hypothesis or any findings that have already been made
Explanation:
by performing experiments scientists get to test out any questions they have
