VladimirAG [237]3 years ago
5 0

Answer:

Both densities would be equal.

Explanation:

since both the bar and the ingot are pure gold, they would have the same density, despite the amount.

How well did tossing the pennies simulate half lives?
SSSSS [86.1K]
Its a 50% chance that approx 1/2 of the pennies will land on tails. The next toss will result the same. and so on and so on. showing how a reaction would slowly eliminate 1/2 of the remaining lives per reaction, until nothing is left. I think it is a good stimulation.

A 420-N force acts on a 400-N object, and the force is from the north. In which direction will the object move?
garik1379 [7]

Answer: The object will move in the South direction.

Explanation: We are given an object of 400 N and force acting on it is 420 N from the north direction, it means the force is acting towards south.

The object will move in the direction of the net force, which is south direction.

Hence, the correct option is A.

The Change in Gibb's free energy, ΔG for the reaction at 298K is; -56.92KJ.

<h3>Gibb's free energy of reactions</h3>

It follows from the Gibb's free energy formula as expressed in terms of Enthalpy and Entropy that;

  • ΔG = ΔH - TΔS

On this note, it follows that;

  • ΔG = 14.6 - (298× 0.24)

Hence, the Gibb's free energy for the reaction is;

  • ΔG = 14.6 - 71.52
  • ΔG = -56.92KJ

Remarks: The question requires that we determine the Gibb's free energy for the reaction at 298K.

A ____________ is the smallest unit of a compound that retains the unique properties of the compound
cluponka [151]
Compounds are made up of elements that exist in a fixed proportion.  These elements are composed of atoms.  Now, the atom has subatomic particles (proton, neutron and electrons), however, these particles lack the ability to take part in chemical reactions by themselves; the smallest unit of a compound that can take part in a chemical reaction, therefore, is an ATOM. 

Thus, an AT<span>OM is the smallest unit of a compound that retains the unique properties of the compound</span>
