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.

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.

Based on the concentrations given, the volume of vinegar required is 5.04 mL.

The concentration of a solution is the amount of solute in a given volume of solution.

Concentration can be expressed as:

The 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.

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.

Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.

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.
