24 g of Magnesium is required to displace H₂ gas from two moles of HCl
A chemical equation is said to be balanced when the number of atoms of all elements on both the reactant and product side of the equation is equal
It follows the the law of conservation of mass.
Let us take the example of balanced equation for magnesium and hydrochloric acid:
The reaction between Magnesium (Mg) and Hydrochloric acid (HCl) is given as:
Magnesium + Hydrochloric acid → Magnesium chloride + hydrogen gas
symbollically,
Mg(S) +HCl(aq) → MgCl₂ (aq) +H₂(g)
Now, we will count the number of atoms of each element on both sides of the reaction.
element reactant side product side
Mg 1 1
H 1 2
Cl 1 2
Now to balance the number of atoms of H and Cl, we will put 2 before HCl on the reactant side.
Thus, the balanced equation becomes:
Mg(S) + 2HCl(aq) → MgCl₂ (aq) +H₂(g)
1 mole of Magnesium is required to displace H₂ gas from two moles of HCl .
mass of 1 mole of magnesium is 24 g.
Thus, 24 g of Magnesium is required to displace H₂ gas from two moles of HCl .

[tex]\boxed{\boxed{\Large\textsf{$\sf mass = 3.4 \times 63.02=214.3$ g (4 s.f)}}}[/tex]
Explanation:The mass of nitric acid (HNO₃) can be determined by considering the relationship between number of moles, mass, and molar mass:
[tex]\boxed{\large\textsf{$\sf\displaystyle number\ of\ moles\ (mol)=\frac{mass\ present\ (grams)}{molar\ mass\ (g/mol)}$}}[/tex]
Rearranging this formula to find mass, therefore, mass present = number of moles ÷ molar mass:
[tex]\boxed{\large\textsf{$\sf\displaystyle mass=moles\times molar\ mass$}}[/tex]
Since we are already given the number of moles of HNO₃ present, we just need the molar mass. The molar mass of elements can be found on any standard periodic table, and the molar mass of a compound is just the sum of all the molar masses of the elements in the compound.
∴ molar mass HNO₃ = H (1.008) + N (14.01) + O₃ (3×16.00) = 63.02 g/mol.
Now plugging in all our values into the formula:

What is found outside the nucleus of the atom and is the location of all electrons in the atom?
Answer:
Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
A positron is a particle emitted from the nucleus that has the same mass as a(n) a. neutron but has a positive charge b. alpha particle c. proton emitted from the nucleus d. beta particle e. electron but has a positive charge
A positron is a particle emitted from the nucleus that has a positive charge and same mass as an electron.
What is an electron?An electron is a subatomic particle with a negative charge that can be free or bound to an atom. One of the three primary types of particles found within an atom is an electron that is bound to it; the other two are protons and neutrons.
A positron is the antiparticle of an electron. This means that it has the same mass as an electron but has the opposite charge. The mass of a particle is determined by the properties of the particle itself, while the charge is determined by the interaction of the particle with other particles or fields. The fact that positrons have the same mass as electrons but have a positive charge is a fundamental property of the universe and is a result of the symmetries that govern the behavior of subatomic particles.

Al2O3 does not use Greek prefixes since it is an ionic compound, while N2O3 does use Greek prefixes since it is a molecular compound.
What is molecular compound?A molecular compound is a chemical compound consisting of two or more atoms held together by covalent bonds. Covalent bonds are formed when atoms share one or more of their electrons with another atom in order to complete their outer electron shell.
The main difference between Al2O3 (aluminum oxide) and N2O3 (dinitrogen trioxide) is that Al2O3 is an ionic compound (made up of charged ions) and N2O3 is a molecular compound (made up of covalently bonded molecules). Therefore, the naming conventions for these two types of compounds are different. For ionic compounds, the name includes the names of the cation and anion (aluminum and oxide, respectively) and their charges (Al2+ and O3-). For molecular compounds, the prefixes are taken from the Greek language to indicate the number of atoms of each element in the molecule (di- for two nitrogen atoms and tri- for three oxygen atoms). Therefore, Al2O3 does not use Greek prefixes since it is an ionic compound, while N2O3 does use Greek prefixes since it is a molecular compound.

The reactants are in the aqueous phase, while the product is in the solid phase and water is in the liquid phase.
What is aqueous phase?Aqueous phase is a term used to describe a solution in which water is the solvent. This type of solution is commonly used in chemistry, as water is an excellent solvent for many different types of compounds. In an aqueous solution, the molecules of the solute are dissolved into the water molecules and are then evenly distributed throughout the solution. This process is driven by the strong intermolecular forces between water molecules, which allows them to attract and form strong bonds with other molecules.

Using stoichiometry, determine the amount of baking soda, in grams, needed to react with the grams of acetic acid in
15.0 mL of vinegar. Show all work.
Answer:
Explanation:
15.0 mL of vinegar is equivalent to 15.0 g of vinegar, since the density of vinegar is 1.0 g/mL. Vinegar is composed of mostly acetic acid (CH3COOH) and water. The density of acetic acid is 1.05 g/mL, so 15.0 mL of vinegar is equivalent to approximately 14.3 g of acetic acid.
The balanced equation for the reaction between sodium bicarbonate (baking soda) and acetic acid is:
NaHCO3 + CH3COOH → NaCH3COO + H2O + CO2
For every mole of acetic acid, we need one mole of sodium bicarbonate. We can use the molar mass of acetic acid (60.05 g/mol) and sodium bicarbonate (84.01 g/mol) to calculate the amount of baking soda needed.
14.3 g of acetic acid x (1 mol/60.05 g) = 0.238 mol acetic acid
0.238 mol acetic acid x (84.01 g/mol) = 19.9 g baking soda
Therefore, 19.9 g of baking soda is needed to react with the 15.0 g of acetic acid in 15.0 mL of vinegar.

h. CH3CH2CH3
He (c). He has the highest average kinetic energy per mole at 298 K.
What is kinetic energy?Kinetic energy is the energy of motion. It is energy that an object has because of its motion. Kinetic energy can be found in both moving objects and particles, such as a ball rolling down a hill, a car moving down a highway, or electrons moving around an atom. Kinetic energy is determined by the mass of the object and its velocity.
Because it has the most number of atoms per mole compared to the other gases listed (2 atoms per mole for He, compared to 2 atoms per mole for H2, 16 atoms per mole for H2O, and 32 atoms per mole for CO2). The higher number of atoms per mole means more kinetic energy per mole, resulting in He having the highest average kinetic energy per mole.
