<span>If the entropy is greater than the enthalpy, it will have more spontinaity</span>
Stella [2.4K]3 years ago
6 0

Explanation:

Since the given reaction is endothermic, therefore value of \Delta H is positive. Also, it is given that value of \Delta S is positive, that is, there will be increase in entropy.

Hence, relation between spontaneity and entropy is as follows.

              Delta G = \Delta H - T \Delta S

                                   = +ve - (+ve. +ve)

                                   = +ve - ve

                                   = -ve

Therefore, we can conclude that there will be increase in spontaneity of the said reaction.

As you may have experienced yourself, water alone will not remove oil from a dirty dish. Why does soap work to remove oil
Alexandra [31]

Answer:

Soap breaks up the oil into smaller drops, which can mix with the water. It works because soap is made up of molecules with two very different ends (one end of molecules are hydrophilic, so they love water; the other end of molecules is hydrophobic, so they hate water).

Q1: An object with a charge of 1.2 C is located 4.5 m away from a second object that has a charge of 0.36 C. Find the electrical
gizmo_the_mogwai [7]

Answer:

a) F= 0,19  [N]   according to problem statement

b) F = 0,19*10⁹ [N]  using the right value of K

Explanation:

The force between two electric charges is according to Coulomb´s law is:

F = K * q₁*q₂ / d²    where  q₁  and q₂ are the charges on body one and body 2 respectively, d is the distance between the two bodies and K is a constant  K = 8,988100*10⁹ N.m²/C². The problem establishes to use        K = 8,988100 N.m²/C².

NOTE: To value of is :  K = 8,988100*10⁹ N.m²/C². I am going to solve the problem using K = 8,988100 N.m²/C² if that information was an error, all we need to get the right answer is multiply the result by 10⁹

Then:

F = 8,988100 * 1,2* 0,36 / (4,5)²     [ N*m²/C² ] * [ C*C*/m²]

F = 3,882859/ 20,25  [N]

F= 0,19  [N]

The force is of repulsion since the two charges are positive and in the direction of the straight line which passes through the centers of the bodies

A toy car has a 1.5 A current, and its resistance is 2 Ω. How much voltage does the car require?
Brums [2.3K]

Answer:

Battery Voltage

Explanation:

Voltage refers to the amount of electrical potential your battery holds. The standard automotive battery in today's vehicles is a 12-volt battery. Each battery has six cells, each with 2.1 volts at full charge. A car battery is considered fully charged at 12.6 volts or higher. hope this helps you :)
