Explanation:
thank you!
have a great week
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.

Common Name Tetraselenium tetranitride
CAS Number 12033-88-4 Molecular Weight
Density N/A Boiling Point
Molecular Formula Se4N4 Melting Point
MSDS N/A Flash Point
Chemical formulas are the representation of the chemical elements with their symbols. The chemical formula for the tetraselenium tetranitride compound is S₄N₄.
What is a chemical formula?
A chemical formula is the representation of the chemical molecule and compound by their symbols and the number of the constituent in the structure. It is represented by the use of the chemical symbol, numbers in superscript and subscript, parentheses, and signs like - and +.
The chemical formula for the tetraselenium tetranitride compound must contain the element symbol of selenium (S) and nitride (N). There are four numbers of both the elements and hence can be represented by, S₄N₄.
Therefore, S₄N₄ is the chemical formula for tetraselenium tetranitride.

Why isn't there a lunar eclipse every time Earth is in between the sun and
the Moon?
There is no lunar eclipse every time Earth is in between the sun and
the Moon as a result of the orbit of the moon being tilted relative to the
orbit of the Earth around the sun.
What is Lunar eclipse?This is a phenomenon which occurs when the Sun, Earth, and Moon are
closely aligned with Earth being between the other two bodies.
The orbit being tilted ensures that the moon often passes below or above
Earth which is the main reason why lunar eclipse doesn't occur all the time
and makes it most appropriate.

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.

How many moles of iron is needed to react completely with 5.00 moles of sulfur to form iron
Fe + S -->
no
Answer:
5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur
Explanation:
The balanced equation in this question is
Iron + Sulfur = Iron(II) Sulfide
Fe (II) + S --> Fe(II)S
Thus one mole of sulfur reacts with one mole of Fe(II)
Hence, 5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur

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.
