Correct me if I am wrong, but I don't think radiation transfers heat.
Answer:
P = 5.868 atm
Explanation:
- Pt = (PN2O)(XN2O) + (PO2)(XO2)
assume T = 25°C = 298.15 K
∴ PN2O = 1 atm
∴ XN2O = nN2O/nt
∴ n = PV/RT....ideal gas
⇒ nN2O = ((1atm)(1L))/((0.082atm.L/K.mol)(298.15K)) = 0.041 mol N2O
∴ PO2 = 6 atm
∴ XO2 = nO2/nt
∴ nO2 = ((6atm)(6L))/((0.082atm.L/K.mol)(298.15K)) = 1.472 mol O2
⇒ nt = nN2O + nO2 = 0.041 + 1.472 = 1.513 mol
⇒ XN2O = 0.041/1.513 = 0.03
⇒ XO2 = 1.472/1.513 = 0.973
⇒ Pt = ((1atm)(0.03)) + ((6atm)(0.973))
⇒ Pt = 5.868 atm
Light is energy that travels in a ray which is a narrow beam of light. We can see things because light bounces off things and goes into our eyes. You can also see things that give off their own light.
Light comes from many different sources which is the place where something begins or comes from. The largest light source is the sun and without it, Earth would be cold and dark. Stars make light too. So do things like lightbulbs, candles, computers, and TVs.
Explanation:
Defining law of definite proportions, it states that when two elements form more than one compound, the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers.
A. One of the oxides (Oxide 1) contains 63.2% of Mn.
Mass of the oxide = 100g
Mass of Mn = 63.2 g
Mass of O = 100 - 63.2
= 36.8 g
Ratio of Mn to O = 63.2/36.8
= 1.72
Another oxide (Oxide 2) contains 77.5% Mn.
Mass of oxide = 100 g
Mass of Mn = 77.5 g
Mass of O = 100 - 77.5
= 22.5 g
Ratio of Mn to O = 77.5/22.5
= 3.44
Therefore, the ratio of the masses of Mn and O in Oxide 1 and Oxide 2 is in the ratio 1.72 : 3.44, which is also 1 : 2. So the law of multiple proportions is obeyed.
B.
Oxide 1
Mass of Mn per 1 g of O = mass of Mn/mass of O
= 77.5/22.5
= 3.44 g/g of Oxygen.
Oxide 2
Mass of Mn per 1 g of O = mass of Mn/mass of O
= 77.5/22.5
= 3.44 g/g of Oxygen.
Quick summary:
Homeostasis describes an environment that supports the survival of cells. It is achieved by making sure the temperature, pH (acidity), and oxygen levels (and many other factors) are set just right. All of your body's systems work together to maintain homeostasis inside your body.
key sentences:
-Homeostasis is a term that is used to both describe the survival of organisms in an ecosystem and to describe the successful survival of cells inside of an organism.
-Organisms and populations of organisms can maintain homeostasis in an environment when they have a steady level of births and deaths.
-It is similar to the idea of equilibrium.
-All of your body's systems work together maintain homeostasis inside of your body.
-Homeostasis is achieved by making sure the temperature, pH (acidity), and oxygen levels (and many other factors) are set just right for your cells to survive.
Summary paraphrased a bit: (<em>Might not 100% make sense grammatically, but it can be a decent guide)</em>
Homeostasis describes an environment which promotes cell survival. It is done by ensuring that the levels of temperature , pH (acidity), and oxygen (and several other variables) are set just right. To maintain homeostasis within your body, all of your body's systems work together.
