Helium: The new volume of the balloon is 0.6182 L.
Colorless, odourless , tasteless, inert, non-toxic helium is a monatomic gas. It is the lightest element in the periodic table and the second most abundant element in the universe.
The new volume of the balloon can be calculated using the ideal gas law, which states that PV = nRT, where P is the n represents the number cubic moles of gas, V represents the volume, R is the real gases constant, and the temperature is T.
First, we need to calculate the number of moles of helium in the balloon after the additional 0.670 grams have been added:
n = 0.670 g He/4.003 g/mol = 0.167 mol
The total number of moles in the balloon is now 0.267 mol. We can use the ideal gas law to calculate the new volume:
V = (0.267 mol)(0.0821 L·atm/K·mol)(273 K)/1 atm = 0.6182 L

Which equation obeys the law of conservation of mass? h2(g) o2(g) → h2o(g) h2(g) o2(g) → h2o(g) 4he(g) 2h2(g) o2(g) → 2h2o(g) h2(g) → h2o(g) h2(g) o2(g) → 2h2o(g)
2H(g) + [tex]O_{2}[/tex] ⇒ 2H2O This equation obeys the law of conservation of mass.
The law of conservation of mass states that mass is neither created nor destroyed in chemical reactions. For example, carbon atoms in coal become carbon dioxide when burned. A carbon atom changes from a solid structure to a gas, but its mass remains the same.
In a chemical reaction, the mass of the chemical components before the reaction equals the mass of the components after the reaction. Therefore, for chemical reactions and low-energy thermodynamic processes in isolated systems, the total mass of reactants or starting materials must equal the mass of the products.

The rate of effusion of a particular gas was measured and found to be 21.0 mL/min. Under the same conditions, the rate of effusion of pure methane (CH4) gas is 47.0 mL/min. What is the molar mass of the unknown gas
the particular gas effusion was 21.0. and the methane effusion rate is 47.0 The molar mass of the unknown gas is approximately 28.6 g/mol
The process through which a gas manages to escape through with a small hole or highly permeable barrier is known as effusion. A gas's rate of effusion is inversely proportional to its molar mass squared. The following equation describes this relationship: rate1 / rate2 = (sqrt(molar mass2) / sqrt(molar mass1)). where rate1 and rate2 are the rates of effusion of the two gases and molar mass1 and molar mass2 are the molar masses of the two gases.Given the rate of effusion of the unknown gas is 21.0 mL/min, and the rate of effusion of pure methane (CH4) is 47.0 mL/min, we can use the above equation to find the molar mass of the unknown gas:
(21.0 mL/min) / (47.0 mL/min) = sqrt(molar mass unknown) / sqrt(16.04 g/mol)
Squaring both sides of the equation, we get:
(21.0 mL/min)^2 / (47.0 mL/min)^2 = (molar mass unknown) / (16.04 g/mol)
Solving for molar mass unknown we get:
molar mass unknown = (16.04 g/mol) * (21.0 mL/min)^2 / (47.0 mL/min)^2
The molar mass of the unknown gas is approximately 28.6 g/mol
Please note that the above calculation is based on the assumption that the temperature and pressure are the same for both gases and that the gases are ideal

Why do different substances have different properties?
Different substances have different properties because of the differences in their atomic and molecular structure, bonding types, and strength of their chemical bonds. These differences can be due to the number of atoms, the arrangement of atoms, and the types of electrons involved in the bonding.
The properties of elements and compounds are determined by the types and arrangements of the atoms that make up the substance. For example, water (H2O) and hydrogen peroxide (H2O2) have different properties due to their different molecular structures. Water is made up of two hydrogen atoms and one oxygen atom, while hydrogen peroxide is made up of two hydrogen atoms and two oxygen atoms. may have different characteristics. The strength of chemical bonds between atoms or molecules can be affected by the number and type of electrons involved in the bond. Because of this, some substances are more stable than others and have higher melting and boiling points.

An ideal gas is a gas composed of a large number of identical molecules that obey the ideal gas law.
What do you mean by Gas?
Gas is a state of matter made of atoms and molecules that are not bound together, allowing them to move freely and take the shape and volume of their container. It is one of the four fundamental states of matter (the others being solid, liquid, and plasma).
The heat exchanged in a two-step process is given by
q = CpΔT + (P1V1 – P2V2)
where Cp is the specific heat capacity of the gas, ΔT is the change in temperature, P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
For the two-step process,
q = CpΔT + (2.00 atm x 6.40 L – 2.50 atm x 3.20 L)
For the one-step process,
q = CpΔT + (2.50 atm x 6.40 L – 2.50 atm x 2.56 L)
The difference in q for the two-step process and the one-step process is
q2 – q1 = (2.50 atm x 3.20 L – 2.00 atm x 6.40 L)
q2 – q1 = (7.68 L atm – 12.80 L atm)
q2 – q1 = -5.12 L atm
Since 1 L atm = 101.3 J, the difference in q for the two-step process and the one-step process is
q2 – q1 = -5.12 L atm x 101.3 J/L atm
q2 – q1 = -517.4 J.
Hence, the difference is -517.4 J.

Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones,mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones.

which of the folowing molecules has the most polar bond between the bonded atoms in terom of greatedst end
The correct response is b) N - H. Because nitrogen is one of the most electronegative elements in the periodic table, its bond with hydrogen will be the most polar of all.
What exactly is a polar bond?A polar covalent bond is a covalent association in which the atoms' electron attraction is uneven, resulting in unequal electron sharing. In a polar covalent bond, also known as a polar bond, the distribution of electrons surrounding the molecule is no longer symmetrical. Polar covalent bonds have an unequal distribution of electrons. The difference in electronegativity between the two elements would be between 0.4 and 1.7. The electronegativity gap between polar and nonpolar bonds is less than 0.4.
In this case, the right answer is b) N - H. Because nitrogen is one of the periodic table's most electronegative elements, its bond with hydrogen will be the most polar of all.
