HNO3
Explanation:
hydrochloric acid (HCl), sulfuric acid (H 2start subscript, 2, end subscriptSO 4start subscript, 4, end subscript), nitric acid (HNO 3start
You would get 15 Fe because you can multiply the reactants by eachother to get the fe.
Mark as braliest please.
Hope this helps!
Answer:
The molar mass of the vapor is 43.83 g/mol
Explanation:
Given volume of gas = V = 247.3 mL = 0.2473 L
Temperature = T = 100
= 373 K
Pressure of the gas = P = 745 mmHg (1 atm = 760 mmHg)
![P = \displaystyle \frac{745}{760} \textrm{ atm} = 0.9802 \textrm{ atm}](https://tex.z-dn.net/?f=P%20%3D%20%5Cdisplaystyle%20%5Cfrac%7B745%7D%7B760%7D%20%5Ctextrm%7B%20atm%7D%20%3D%200.9802%20%5Ctextrm%7B%20atm%7D)
Mass of vapor = 0.347 g
Assuming molar mass of gas to be M g/mol
The ideal gas equation is shown below
![\textrm{PV} =\textrm{nRT} \\\textrm{PV} = \displaystyle \frac{m}{M}\textrm{ RT } \\0.98026 \textrm{ atm}\times 0.2473 \textrm{ L} = \displaystyle \frac{3.47 \textrm{ g}}{M}\times 0.0821 \textrm{ L.atm.mol}^{-1}.K^{-1}\times 373\textrm{K} \\M = 43.834 \textrm{ g/mol}](https://tex.z-dn.net/?f=%5Ctextrm%7BPV%7D%20%3D%5Ctextrm%7BnRT%7D%20%5C%5C%5Ctextrm%7BPV%7D%20%3D%20%5Cdisplaystyle%20%5Cfrac%7Bm%7D%7BM%7D%5Ctextrm%7B%20RT%20%7D%20%5C%5C0.98026%20%5Ctextrm%7B%20atm%7D%5Ctimes%200.2473%20%5Ctextrm%7B%20L%7D%20%3D%20%5Cdisplaystyle%20%5Cfrac%7B3.47%20%5Ctextrm%7B%20g%7D%7D%7BM%7D%5Ctimes%200.0821%20%5Ctextrm%7B%20L.atm.mol%7D%5E%7B-1%7D.K%5E%7B-1%7D%5Ctimes%20373%5Ctextrm%7BK%7D%20%5C%5CM%20%3D%2043.834%20%5Ctextrm%7B%20g%2Fmol%7D)
The molar mass of the vapor comes out to be 43.834 g/mol
The reactants are A: Carbon Dioxide and water
Anything that happens on Earth leaves a record in the rocks: sandstone is the remains of sands that were once sediment in a river or ocean, lava is the remains of past volcanic eruptions, fossils are the remains of once-living things that got buried and preserved. Additionally, there are some simple logical rules as well: if you lay some layer of sediment or rock down from the water, then it will be lying on top of whatever was underneath it, and, therefore, younger sediments will be on top of older sediments.
The predictions come from what we call the "principle of uniformitarianism", which states that the processes acting on the earth in the past are the same as the processes acting on the earth today and are the same as the processes that will act on the earth in the future. This is an assumption that we make, indeed that all science makes, which is that the universe has rules that describe how it behaves. For instance, if we look at the debris from a flood that happened yesterday, and then we look at debris from the past that look the same, we can infer that the previous debris were created in a flood. If we look through the record and see that floods of some scale happen every thousand years or so, then we can predict that they will continue to do so into the future.
