Answer:
A 0.239mol
Explanation:
From the equation:
We were given that 10g of iron was involved in this chemical reaction
We can establish that :
3moles of Fe would produced 4 moles of Hydrogen gas
Therefore:
Number of moles of iron = mass of Fe / mloar mass of iron
Mass of Fe = 10g
Molar Mass of Fe = 55.85g/mol
Therefore, number of moles of iron= 10/55.85
Number of moles of iron = 0.179mol
3moles of Fe would produced 4 moles of Hydrogen gas
So, 0.179mol of Fe would give 0.179x4/3
The number of mole of Hydrogen gas produced is 0.239mol.
Explanation:
When a plate moves it shifts the earth, and it can cause an earthquake.
A fault is where two of earth's tectonic plates come together. They can slide against the other, causing earthquakes, they can push against each other causing mountains to form, and they can move apart from each other, causing valleys or trenches.
Answer:
d. 103.3
Explanation:
In the given question, the National Weather Service routinely supplies atmospheric pressure data to help pilots set their altimeters. And the units of atmospheric pressure used for reporting the atmospheric pressure data are inches of mercury. For a barometric pressure of 30.51 inches of mercury, we can calculate the pressure in kPa as follow:
In principle, 3.386 kPa is equivalent to the atmospheric pressure of 1 inch of mercury. Thus, 30.51 inches of mercury is equivalent to 30.51 in *(3.386 kPa/1 in) = 103.307 kPa.
Therefore, a barometric pressure of 30.51 inches of mercury corresponds to _____103.3_____ kPa.
