Calculate the volume of a 0.15 mol dm-3 Ba(OH)2 solution required to completely neutralize 45 cm3 of a 0.29 mol dm-3 HNO3 solution. Note: Ba(OH)2 + 2HNO3 --> Ba(NO3)2 + 2H2O
Answers
Answer:
[tex]V_{base}=43.5cm^3[/tex]
Explanation:
Hello there!
In this case, given the neutralization chemical reaction of barium sulfate and nitric acid, it is possible to evidence the 1:2 mole ratio between them; thus, at the equivalence point we have:
[tex]2n_{base}=n_{acid}[/tex]
Which in terms of molarities and volumes is:
[tex]2M_{base}V_{base}=M_{acid}V_{acid}[/tex]
In such a way, by solving for the volume of base, we proceed as follows:
[tex]V_{base}=\frac{M_{acid}V_{acid}}{2M_{base}} \\\\V_{base}=\frac{45cm^3*0.29mol*dm^{-3}}{2*0.15mol*dm^{-3}} \\\\V_{base}=43.5cm^3[/tex]

Air is made up mostly of O2, N2, and CO2. If the total pressure of air is 765mmHg and P(N2) = 0.79 atm and P(CO2) = 0.05 atm, then what is the partial pressure of the O2?
Answers
Answer:
the partial pressure of the O2 is 0.167 atm
Explanation:
The computation of the partial pressure of the O2 is shown below:
As we know that
P = P_N2 + P_O2 + P_CO2
P_O2 = P - P_N2 - P_CO2
= (1.007 - 0.79 - 0.05)
= 0.167 atm
Hence, the partial pressure of the O2 is 0.167 atm
we simply applied the above formula

Indium-110
Palladium-109
Answers
Answer:
Rhodium-122 < Palladium-109 < Silver-109 < Cadmium-106 < Indium-110
Explanation:
Atomic number - Number of protons.
The number displayed at the end of the element in this question represents the mass number (Number of protons + Number of neutrons).
The atomic number of the isotopes are given below;
Silver-109 --> 47
Cadmium-106 --> 48
Rhodium-122 --> 45
Indium-110 --> 49
Palladium-109 --> 46
Arranging in order of increasing atomic number from lowest to highest;
Rhodium-122 < Palladium-109 < Silver-109 < Cadmium-106 < Indium-110
Scientist are studying photosynthesisIn in a forest ecosystem that has plants animals and decomposers
Answers
Answer:
Ecosystem is food web of primary and secondary producers and consumers.
Explanation:
In an ecosystem, there exist primary producers, primary consumers, secondary consumers, and tertiary consumers such as detritivorous such as viruses and bacteria that act on the living bodies and recycle the nutrients back to plants through the soil. The primary producers such as all green plants and others make their own food being autotrophs they use sunlight and carry out photosynthesis process. On the depend on the herbivorous they eat grass etc. The secondary consumers are carnivores as heterotrophs that feed on herbivores.If the Earth were to spin half as fast as it does now, how many hours would be in one day (one complete spin)?

What would happen to Earth's temperature if the energy absorbed from the sun (solar radiation) was less than the emitted (thermal) energy leaving the Earth?
Answers
Answer:
The Earth would become cooler until it probably attains a new equilibrium between absorbed solar energy and emitted solar energy.
Explanation:
The earth's energy balance refers to the balance between the energy absorbed from the sun (solar radiation) and the emitted (thermal) energy leaving the Earth. This balance ensures that the earth's surface temperature remains fairly constant.
When energy from the sun reaches the earth, it is absorbed and used by various features of the earth which uses it for their energy needs. Eventually, any excess radiant energy is sent back or emitted from the earth back into space such that the balance between absorbed and emitted energy is maintained.
However, if there is an imbalance whereby more energy is emitted than is absorbed, this would result in the earth losing more heat than it receives. This would result in the earth becoming more significantly colder until it probably attains a new equilibrium between absorbed solar energy and emitted solar energy.
Explain how low atomspheric oxygen levels affected alligators growth in terms of celluar respiration
Answers
Answer:
Answer: Hyperoxic alligators show significantly lower breathing rates than their siblings in normoxic and hypoxic groups. Conversely, each breath supports greater oxygen consumption in hyperoxic animals than in other groups. Statistical significance between groups was calculated by ANOVA with post hoc Tukey-Kramer
The explanation regarding the less atmospheric oxygen levels impacted the alligators growth should be because of Hyperbolic alligators.
What is Hyperbolic alligators?There should be less breathing rate and the consumption of the oxygen should be high per breath.
The compensatory cardiopulmonary remodeling, the growth of the hypnotic alligators should be constrained by the less temperature with respect to the supply of the oxygen that should limited the food utilization capacity.

If both samples contain the same amount of gas, which sample has a greater volume? use your knowledge of gas laws to explain your answer
Answers
Answer:A modern statement is: Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
Explanation:
The Avogadro's law is used here to determine the volume of the gas. Here the both samples have equal volume since they contain the same amount of gas.
What is Avogadro's law?The Avogadro's law states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules. Mathematically the law can be expressed as:
V ∝ n
The gases show great uniformity in their behaviour irrespective of their nature. Some useful generalisations have been deduced from the behaviour of gases which are known as gas laws.
The Avogadro's law follows that the volume of a gas is directly proportional to the number of molecules. But the number of molecules (N) of any gas is directly proportional to its number of moles (n).
So here if both samples contain the same amount of gas, both of them have the equal volumes. We cannot determine one with greater volume.
