A solution of 0.2 M Sulfuric acid is titrated with a 0.2 M basic solution. In three to five sentences, explain how you can use the results of the titration as evidence for the ratio of sulfuric acid and the base in the balanced chemical reaction for the titration.
If there are 0.2 M solutions of both acid and base, the concentrations of hydrogen and hydroxide ions will be equal at equivalence point.
The reaction of sulfuric acid and a basic solution BOH occurs as follows;
H2SO4(aq) + 2BOH(aq) -----> B2SO4(aq) + 2H2O(l)
In the question, we are told that that both the solution of the sulfuric acid and the basic solution are 0.2 M.
The point where all the hydrogen and hydroxide ions have reacted according to the stoichiometry of the reaction. If there is really equimolar amounts of acid and base, the concentration of hydrogen and hydroxide ions will be equal at equivalence point.

From the stoichiometry of the reaction, the mass of AgNO3 required is 340 Kg.
Number of moles of I2 produced in the third step = 254 × 10^3 g/254 g/mol = 1000 molesIn the first step, 1 mole of AgNO3 produces 1 mole of AgIIn the second step, 2 moles of AgI produces 1 mole of FeI2
In the third step, 2 moles of FeI2 produces 2 moles of I2
Hence;In the third step;
1000 moles of I2 is produced by 1000 moles of FeI2
In the second step;2 moles of AgI produces 1 mole of FeI2
x moles of AgI produces 1000 moles of FeI2
x = 2 moles × 1000 moles/ 1 mole
x = 2000 moles
In the first step;2000 moles of AgI is produced by 2000 moles of AgNO3
Mass of AgNO3 required = 2000 moles of AgNO3 × 170 g/mol = 340 Kg

how long is a frozen turkey good for in the freezer?
Answer: Turkeys are good for up to 2 years if frozen well in a good freezer
I recommend to at least cooking it within 1 year for the best quality if you cook it in 2 years it may lose some of its quality taste-wise.
if it's not frozen well check the texture and smell to see if its gone bad. it also depends on the type of turkey you are buying, depending on the turkey you purchase always check for an expiration date such as a butterball turkey, so make sure you check their date.

Answer:
Natures such as plants captures the suns energy and make their food through photosynthesis while Organisms get it energy by eating food
Explanation:
Photosynthesis is the act of transforming sunlight into energy. This is what plants (or natures) do to make their food.
In comparison, animals (or organisms) have to eat their food either by eating the plants (herbivores) or through other animals (carnivores)
This creates a food chain that energy travels down.

Answer: It's a modern-day engineering challenge to remove human-made contaminants from
drinking water. After a quick review of the treatment processes that municipal water
goes through before it comes from the tap you will learn about the still-present
measurable contamination of drinking water due to anthropogenic (human-made)
chemicals. Substances such as prescription medication, pesticides and hormones are
detected in the drinking water supplies of American and European metropolitan cities.
The engineering design process can be used to design solutions for a real-world
problem (contaminated water) that could affect health.
Engineering Connection
The water that comes from our faucets has passed through a complex system designed
by many different types of engineers. Civil, chemical, electrical, environmental,
geotechnical, hydraulic, structural and architectural engineers all play roles in the
design, development and implementation of municipalities' drinking water supplies and
delivery systems. Hydraulic engineers design systems that safely filter the water at a
rate needed to supply a specific region and population. Chemical engineers precisely
determine the amounts and types of chemicals added to source water for coagulation
and decontamination to make the water safe to drink and not taste bad. Even so,
modern pharmaceutical and agricultural practices persist in contaminating our water
supplies.

Why is fusion not used to generate electrical power?
Answer:
One of the biggest reasons why we haven't been able to harness power from fusion is that its energy requirements are unbelievably, terribly high. In order for fusion to occur, you need a temperature of at least 100,000,000 degrees Celsius. That's slightly more than 6 times the temperature of the Sun's core.
Explanation:
Answer:
The energy requirements for fusion is too high to be used to generate electrical power.

A sample of gas exhibits ideal behavior and occupies a volume of 350. mL at 25.0C and 1.00atm. How many moles of gas are present in the sample?
The number of mole of the gas present in the sample which occupies a volume of 350 mL at 25 °C and 1 atm is 0.0143 mole
From the question given above, the following data were obtained:
Volume (V) = 350 mL = 350 / 1000 = 0.35 L
Temperature (T) = 25 °C = 25 + 273 = 298 K
Pressure (P) = 1 atm
Gas constant (R) = 0.0821 atm.L/Kmol
Number of mole (n) =?With the application of the ideal gas equation, the number of mole of the gas present in the sample can be obtained as follow:
PV = nRT1 × 0.35 = n × 0.0821 × 298
0.35 = n × 24.4658
Divide both side by 24.4658
n = 0.35 / 24.4658
n = 0.0143 moleTherefore, the number of mole of the gas present in the sample is 0.0143 mole

Calculate the mass of 6.9 moles of nitrous acid (HNO2). Explain the process or show your work by including all values used to determine the answer.
Answer:
324.4 grams
Explanation:
47.013 g/mol is the molar mass of the nitrous acid.
Therefore with weight, nitrous acid is equal to 47.013 grams.
This value can be utilized to determine the mass of 6.9 moles within the same compound.
Since a single mole = 47.013 grams, we simply multiply:
6.9 x 47.013 = 324.4
The mass of the given nitrous acid contained in 6.9 moles is 324.3 g.
The molecular mass of the given nitrous acid is calculated as follows;
HNO₂ = (1) + (14) + (16 x 2)
M = 47 g/mol
The mass of the given nitrous acid contained in 6.9 moles of the acid is calculated as follows;
m = nM
where;
n is the number of moles of the acidM is the molecular massm = 6.9 x 47
m = 324.3 g
Thus, the mass of the given nitrous acid contained in 6.9 moles is 324.3 g.
