The volume is generally measured in Liters, milliliters, cm³, m³, etc. At constant pressure and temperature, the volume produced by six tablets will be 1200 cm³. The correct option is A.
What is volume?The term volume denotes the capacity that an object can hold. For example if a beaker can hold 100 mL of water then the volume of the beaker is said to be 100 mL. It is represented by the symbol 'V'.
The three dimensional space occupied by the matter is given by the term volume. The SI unit of volume is m³.
Here the volume of three tablets is 600 cm³. Then the volume of one tablet is:
V = 600 / 3 = 200 cm³
Hence the volume produced by six tablets is:
V = 200 × 6 = 1200 cm³.
Thus the volume of six tablets is 1200 cm³.
Thus the correct option is A.

Based on the table above, which amount of a compound dissolved in 100 grams of water at the stated temperature represents a system at equilibrium?
Select one:
a. 40 g NaCl at 70 degrees Celsius
b. 20 g KClO3 at 70 degrees Celsius
c. 80 g NaNO3at 10 degrees Celsius
d. 80 g Pb(NO3)2 at 30 degrees Celsius
Answer:
C. 80g Nano3 at 10 degrees Celsius
Explanation:
I just took the test
80 g NaNO₃ at 10 degrees Celsius of a compound dissolved in 100 grams of water at the stated temperature represents a system at equilibrium. Therefore, option C is correct.
What is solubility ?The maximum quantity of a chemical that will dissolve in a given amount of solvent at a particular temperature is referred to as its solubility.
Different compounds have very varying solubilities, which is a feature of a particular solute-solvent pair.
A substance's physical and chemical characteristics affect how soluble it is. A few other factors and circumstances can also influence it. A few of these are: temperature, pressure, kind of binding, and forces between the particles.
A system is said to be in equilibrium when 80 grammes of a substance, dissolved in 100 grams of water at 10 degrees Celsius.
Thus, option C is correct.

What season is it in earths northern hemisphere when earths northern hemisphere tilts toward the sun
Answer:
Summer
Explanation:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

How many liters of hydrogen are required to react completely with 2.4L of oxygen to form water? 2H2 + O2 --> 2H2O
Answer:
2.4 mole of oxygen will react with 2.4 moles of hydrogen
Explanation:
As we know
1 liter = 1000 grams
2H2 + O2 --> 2H2O
Weight of H2 molecule = 2.016 g/mol
Weight of water = 18.01 gram /l
2 mole of oxygen react with 2 mole of H2
2.4 mole of oxygen will react with 2.4 moles of hydrogen

Explanation:
In order to produce CO2, a student put a sample of calcium carbonate in a flask and added hydrochloric acid using the following equation: Ca(CO3) + HCl → H2O + CO2 + CaCl2 The student finds the mass of CO2 generated to be 100 g. If the student began with 200 g of HCl and there was ample CaCO3 left unreacted, what was the percent yield?
Answer:
82.9% Is the percent yield
Explanation:
First, we need to balance the equation.
Ca(CO3) + 2HCl → H2O + CO2 + CaCl2
Since the problem tells you that the excess reactant is Ca(CO3), we just need to Stoichiometry to solve for the theoretical yield.
[tex]\frac{200g HCl}{1}[/tex] x [tex]\frac{1 mole HCl}{36.46gHCl}[/tex] x [tex]\frac{1 mol CO2}{2molHCl}[/tex] x [tex]\frac{44.01CO2}{1molCO2}[/tex] =120.707 g (theoretical yield)
Take your actual yield of 100g, divide that by 120.707, then multiply that decimical by 100.
can we stir silver nitrate solution with copper spoon? why or why not? support your answer with reason.
↪ Hello miss "galaxyu035" here's your answer for the question you wrote.
Answer :
No, we cannot stir silver nitrate solution with a copper spoon because , copper is more reactive than silver. Thus,it would displace silver from the silver nitrate solution forming copper nitrate.

A cup of coffee is made in the morning by pouring water ov er ground up coffee beans in a piece of paper and by collecting the brown liquid that comes through. Which techniques used
Answer: Filtration technique
Explanation:
The technique used here is called filtration.
Filtration,is a physical separation process that separates a mixture of an insoluble solid from a liquid ( acting as the solvent) by the use of a filter barrier that allows only the fluid to pass through.
In the case from the question,
As water is poured over the ground coffee, it forms a mixture of which the insoluble solid is the coffee grounds, the water is the liquid and the filter barrier is the piece of paper which allows only the brown liquid coffee to pass through as the filtrate.

Answer:
41.88375 g Fe
Explanation:
Using stoichiometry, we can do this problem. First, we put our given. Then we create an equation using the molar mass of Fe (found on the periodic table, which was 55.845 g Fe), and the resulting equation is:
[tex]0.75 mol Fe * \frac{55.845 g Fe}{1 mol Fe}[/tex]

If a radioactive source has a half life of 2 hours how long will it take for the activity to go from 200 to 25?
Answer:
It takes 6h to the radioactive source decrease its activity from 200 to 25
Explanation:
The equation that describes the readioactive decay is:
Ln [A] = -kt + Ln [A]₀
Where [A] could be taken as activity of the source after time t, [A]₀ is initial activity and k is decay constant.
Decay constant could be written as:
k = ln2 / Half-life
k = ln 2 / 2h
k = 0.3466h⁻¹
Replacing in decay equation:
Ln [25] = -0.3466h⁻¹t + Ln [200]
-2.0794 = -0.3466h⁻¹t
6h = t
It takes 6h to the radioactive source decrease its activity from 200 to 25
