Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth

Newton's Second law of motion states that "the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object."

How many grams of barium chloride are produced when 1.25 x 1023 molecules of HCl reacts with barium?

Answers

Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.

Balanced reaction

The balanced reaction is

2 HCl + Ba → BaCl₂ + H₂

Moles of HCl that react

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?

amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms

amount of moles of HCl= 0.2075 moles

Then, 0.2075 moles of HCl react.

Reaction stoichiometry

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

HCl: 2 moles Ba: 1 mole BaCl₂: 1 mole H₂: 1 mole

Mass of barium chloride produced

Then you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?

[tex]amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}[/tex]

amount of moles of BaCl₂= 0.10375 moles

Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:

[tex]0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams[/tex]

Finally, the mass of barium chloride produced is 21.6 grams.

Each cart below is pushed across a room with the same amount of force. Which cart will result in the greatest change in speed?

F.A 75 kg cart being pushed with a 200 N force
G.A 125 kg box being pushed with a 200 N force
H.A 350 kg box being pushed with a 200 N force
J.A 450 kg cart being pushed with a 200 N force

Answers

The cart with the greatest change in speed is the cart with a mass of 75 Kg

Acceleration is defined as the change in velocity of an object with time. Also, acceleration is related to the force and mass according to the following equation:

Acceleration (a) = Force (F) / mass (m)

a = F / m

To answer the question, we shall determine the acceleration of each cart.

For cart of mass 75 kgMass (m) = 75 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 75

a = 2.67 m/s²

For cart of mass 125 kgMass (m) = 125 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 125

a = 1.6 m/s²

For cart of mass 350 kgMass (m) = 350 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 350

a = 0.57 m/s²

For cart of mass 450 kgMass (m) = 450 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 450

a = 0.44 m/s²

From the above illustrations, we can see that the cart with a mass of 75 K has the greatest change in speed (i.e 2.67 m/s²)

How many moles are there in 10 dm3 of sulfur dioxide gas

Answers

Taking into account the room temperature and pressure, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.

RTP refers to Room Temperature and Pressure. Pressure is 1 atm and Temperature is 298K. In this case, one mole of any gas has a volume of 24 dm³ or 24,000 cm³. This volume is called the molar volume of a gas.

In other words, the molar volume (the amount of space occupied by one mole) of any gas is 24dm³ (1 mol of gas molecules occupies 24.0 dm³).

Therefore, the amount of volume occupied by any gas can be calculated by multiplying the number of moles of gas by 24dm³:

Volume = Moles of gas× 24 dm³

So, the number of moles can be calculated as:

Moles of gas= Volume÷ 24 dm³

In this case, you know that volume if sulfur dioxide gas is 10 dm³. So, replacing:

Moles of gas= 10 dm³ ÷ 24 dm³

Solving:

Moles of gas= 0.4167

Finally, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.

Kelli and Jarvis are members of the stage crew for the Variety Show. Between acts, they must quickly move a Baby Grand Piano onto stage. After the curtain closes, they exert a sudden forward force of 524 N to budge the piano from rest and get it up to speed. The 158-kg piano experiences 418 N of friction. a. What is the piano's acceleration during this phase of its motion? b. If Kelli and Jarvis maintain this forward force for 1.44 seconds, then what speed will the piano have?

Answers

If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.

Kelli and Jarvis exert a force of 524 N on a 158- kg (m) piano.

The friction force, which opposes this force, is 418 N.

The net force (F) is the difference between both forces.

F = 524 N - 418 N = 106 N

We can calculate the acceleration (a) of the piano using Newton's second law of motion.

What is Newton's second law of motion?

Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force and inversely proportional to the mass of the object.

a = F/m = 106 N/158kg = 0.671 m/s²

The piano start from rest (u = 0 m/s) and moves with an acceleration of 0.671 m/s² for 1.44 s.

We can calculate its final velocity (v) using the following kinematic equation.

v = u + a × t

v = 0 m/s + 0.671 m/s² × 1.44 s = 0.966 m/s

If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.

If the energy of the H–H bond is 452 kJ/mol. The energy of the O=O bond is 598 kJ/mol. The energy of the O–H bond is 367 kJ/mol, which bond would be the strongest? Which bond would be the weakest?

Answers

Taking into account the bond energy, the O=O bond is the strongest and the O–H bond is the weakest.

The bond energy is the average total energy that would be released by the formation of a mole of chemical bonds, from their constituent fragments (all in the gaseous state).

In other words, the normal or standard bond enthalpy is defined as the change in enthalpy or heat released, under standard conditions of 1 atmosphere and 25ºC, that accompanies the reaction of formation of one mole of bonds from the isolated atoms in gaseous state.

The higher the bond energy, the stronger and more stable the bond will be.

So, taking into account all the previous, the O=O bond is the strongest and the O–H bond is the weakest.
