There are 360 degrees in a circle. How many arcminutes will be in 86% of a circle?
Leokris [45]

Answer:

There are 18572.9 arcminutes in 86% of a circle.

Explanation:

The degrees in 86% of a circle is:

degrees = \frac{86}{100}*360 = 309.6 ^{\circ}

Now, we need to find the number of arcminutes in 309.6°:

arcminute = \frac{59.99 arcminute}{1 degree}*309.6 degrees = 18572.9

Therefore, there are 18572.9 arcminutes in 86% of a circle.

I hope it helps you!

In a galvanic cell, electrons are transferred from one half cell to the other as the redox reaction progresses. what happens in
Sidana [21]

The half cell in which the electrode gains electrons is where reduction occurs, and the half cell in which the electrode loses electrons is where oxidation occurs.

<h3><u>What is a Galvanic cell ?</u></h3>

Voltaic or galvanic cells are electrochemical devices that use spontaneous oxidation-reduction events to generate electricity. In order to balance the overall equation and highlight the actual chemical changes, it is frequently advantageous to divide the oxidation-reduction reactions into half-reactions while constructing the equations.

Two half-cells make up most electrochemical cells. The half-cells allow electricity to pass via an external wire by separating the oxidation half-reaction from the reduction half-reaction.

<h3><u>Oxidation:</u></h3>

The anode is located in one half-cell, which is often shown on the left side of a figure. On the anode, oxidation takes place. In the opposite half-cell, the anode and cathode are linked.

<h3><u>Reduction:</u></h3>

The second half-cell, cathode, which is frequently displayed on a figure's right side. The cathode is where reduction happens. The circuit is completed and current can flow by adding a salt bridge.

What is a limitation of using a chemical formula, such as CGH1206, to represent a compound?
Tpy6a [65]

Answer:

The chemical formula does not show how the atoms are connected to one another.

Explanation:

With a chemical formula, you can see the types of elements that make up the compound, the number of atoms of each element in a molecule, and the chemical symbols of the elements in the compound.

Under which conditions of temperature and pressure does a real gas behave most like an ideal gas
castortr0y [4]

Answer:

Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
