An unknown amount of gas has a volume of 12 L and a pressure of 5.6 atm. If the temperature is 205K, how many moles of gas are present
The number of moles of the gas present is 4 moles.
To calculate the numbers of moles of the gas present, we use the formula below.
Formula:
PV = nRT............. Equation 1Where:
P = PressureV = Volumen = Number of moles of the gasR = molar gas constantT = Temperature.Make n the subject of the equation
n = PV/RT............ Equation 2From the question,
Given:
P = 5.6 atmV = 12 LT = 205 KR = 0.0821 L.atm.K⁻¹.mol⁻¹Substitute these values into equation 2
n = (5.6×12)/(0.0821×205)n = 67.2/16.8305n = 3.99n ≈ 4 molesHence, the number of moles of the gas present is 4 moles.

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()bao2 ()h2so4 → ()h2o2 ()baso4
Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.
What is balanced equation?Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.
Given chemical reaction is:
BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄
Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.
Hence the required coefficients is 1.

If force of 6.0 N causes a 1.0 kg block to accelerate 4.0 m/s2 to
the right, then what is the force of friction acting on the block?
The force of friction acting on the block is -2N.
To find the force of a friction, the given datas are,
Force = 6N
Mass = 1 kg
Acceleration = 4 m/s².
What is the force of friction?The push or pull on an object that made the changes in the velocity with the mass. The object's or body's is to be at motion or at rest will be determined by Force. It has both the magnitude and direction.
The Net Force of the object can be written by:
Fnet = ma
where m is the mass of the object in kg
a is the acceleration of the object in m/s^2
Substituting the values in the formula,
Fnet = (1.0)(4.0)
= 4 N
We also know that Net force is also the sum of all forces acting on an object. In this case Friction and the Pushing Force is acting on the object. Hence we can write that:
Fnet = Pushing Force + (-Friction)
6N = 4 N - Friction
Friction = - 2N
Hence the force of friction is -2 N.

identify the particles that facilitate the electric conductivity of sodium metal
Answer:
Sodium metal will conduct electricity in both a solid and liquid state, due to 'a sea' of delocalised electrons which can move and are able to carry charge
Sodium metal will conduct electricity only when it is in a liquid state or in solution because of the ionic state which are free to move in this state, allowing them to carry charge and conduct electricity.
What are free electrons ?An electron within a conducting substance (as in a Sodium metal) but not permanently attached to any atom.

If your sample of vinegar is approximately 4.76% (w/w), what volume should you use so that approximately 40 mL of 0.1 M NaOH is required to neutralize your sample of vinegar
Based on the concentrations given, the volume of vinegar required is 5.04 mL.
What is the concentration of the vinegar solution?The concentration of a solution is the amount of solute in a given volume of solution.
Concentration can be expressed as:
molar concentration percentage concentrationThe concentration of the vinegar solution is 4.76% (w/w). This means that 4.76 g of vinegar is present in 100 g of solution.
Mass of vinegar = 4.76 g
molar mass if vinegar = 60 g/mol
moles of vinegar = 4.76/60 = 0.0793 moles
volume of solution/water = 100 mL or 0.1 L
Molarity of vinegar = 0.0793/0.1 = 0.793 M
1 mole of vinegar reacts with 1 mole of NaOH
let the volume of vinegar required be V
0.793 M × V = 40 × 0.1
V = 4/0.793
V = 5.04 mL
Therefore, the volume of vinegar require is 5.04 mL.

Explanation:
Avogadro's number, 10 x 10^{23}, represens the number of atoms in a single mole of any substance.
Since we already of have the mole amount and don't need to calculate that from the grams of the substance, we can simply multiple Avogadro's number by the amount of moles given.
