According to Boyle's law, temperature being constant the volume of the balloon at pressure 3.3 atmospheres is 138.18 ml.

Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.

Mathematically, it can be stated as,

P∝1/V or PV=K. The equation states that the product of of pressure and volume is constant for a given mass of gas and the equation holds true as long as temperature is maintained constant.

According to the equation the unknown pressure and volume of any one gas can be determined if two gases are to be considered.That is,

P₁V₁=P₂V₂

Substitution in above equation gives, V₂=1×456/3.3=138.18 ml.

Thus, the volume of balloon is 138.18 ml.

Answer: Friction

Explanation: Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.  Please give me brainliest!!!!!!!

Answer: friction: The resistance an object meets when moving over a surface or through a gas or liquid; it is the force that resists the motion of two surfaces that are touching each other.

Answer:

88%.

Explanation:

The percentage yield of lead sulfate in this experiment is 88% if 2.53 is divided by 2.85 and multiply by 100. The percentage yield can be calculated when the experimental yield is divided by theoretical yield and then multiply by 100. The percentage yield tells us about the actual yield that is gained in the end of experiment which is lower than theoretical yield.

Answer: D: 1.43

The expected density of the given sample of oxygen gas at STP can be calculated using the ideal gas law equation:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

At STP, the pressure is 1 atm and the temperature is 273 K. We are given that the mass of the oxygen gas is 4.8 g. To find the number of moles of oxygen gas, we can use its molar mass, which is 32.00 g/mol:

n = mass / molar mass = 4.8 g / 32.00 g/mol = 0.15 mol

Using the molar volume of an ideal gas at STP, which is 22.4 L/mol, we can find the volume of the oxygen gas:

V = n × molar volume = 0.15 mol × 22.4 L/mol = 3.36 L

Therefore, the expected density of the given sample of oxygen gas at STP is:

density = mass / volume = 4.8 g / 3.36 L = 1.43 g/L

Therefore, the expected density of the given sample of oxygen gas at STP is 1.43 g/L.

Answer:

0.234 mol

Explanation:

m(CaCO3) = 23.4g

n(CaCO3) = ?

M(CaCO3) = 100.09 g/mol

n = m/M

n(CaCO3) = 23.4 / 100.09

                 = 0.234 mol (3 s.f.)

Explanation:

Answer:

mass of CO₂ produced = 5.06 g of CO₂

Explanation:

Equation of the reaction: 2CH₃CH₃ + 5O₂ ---> 4CO₂ + 6H₂O

From the equation of the reaction, 2 moles of gaseous ethane reacts with 5 moles of oxygen gas to produce 6 moles of water.

molar mass of ethane = 30 g/mol

molar mass of oxygen gas = 32 g/mol

number of moles of ethane present in 1.8 g = 1.8/30 = 0.06 moles

number of moles of oxygen gas present in 4.6 g = 4.6/32 = 0.14375 moles

mole ratio of oxygen gas to ethane  = 2.4 : 1

Therefore, oxygen is the limiting reactant

0.14375 moles of oxygen will react with 0.06 moles of ethane to produce 4/5 * 0.14375 moles of CO₂ = 0.115 moles of CO₂

molar mass of CO₂ = 44 g/mol

mass of CO₂ produced = 0.1725 * 44

mass of CO₂ produced = 5.06 g of CO₂

The question is complete, the complete question is;

16.1g of bromine are mixed with 8.42g of chlorite to give an actual yield of 21.1g of bromine monochloride.

Answer:

91 %

Explanation:

Br2 + Cl2 ------>2BrCl

Number of moles of Chlorine = 8.42/71 = 0.119 moles

If 1 mole of Cl2 yields 2 moles of BrCl

0.119 moles of Cl2 will yield 0.119 moles * 2/1 = 0.238 moles of BrCl

Number of moles of Br2 reacted = 16.1/160 = 0.1 moles

If 1 mole of Br2 yielded 2 moles of BrCl

0.1 moles of Br2 yields 0.1 * 2/1 = 0.2 moles of BrCl

Bromine is the limiting reactant.

Mass of BrCl produced = 0.2 moles * 115.357 g/mol = 23.07 g

Theoretical yield = 23.07 g

Actual yield = 21.1 g

Percentage yield = Actual yield/Theoretical yield * 100

= 21.1/23.07 * 100 = 91 %

Molarity of the solution = 0.08 M

Further explanation

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

MW silver nitrat - AgNO₃ = 169,87 g/mol

mol AgNO₃ :

Molarity :

Answer: The molarity of solution is 3.37 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n = moles of solute = 0.614  

[tex]V_s[/tex] = volume of solution in ml = 182 ml

Now put all the given values in the formula of molarity, we get

[tex]Molarity=\frac{0.614\times 1000}{182}=3.37M[/tex]

Therefore, the molarity of solution is 3.37 M
