What is a natural resource that is plentiful, but strong enough to be used as currency?

Chemistry
1 answer:
gayaneshka [121]3 years ago
5 0

Answer:

The two characteristics — “plentiful” and “currency” — are not really related.

Money is a symbolic tool to expedite trade. In earliest days, people might carry bushels of wheat to exchange for jars of oil. But that is cumbersome, and the search costs are too high. It’s hard to find another party who both wants what you have, AND who also has what you want!.

Instead, we all agree on trading with “money.” The farmer gives the store milk and gets money. Later you give the store money and get milk.

SO… The most important characteristic of currency is that it is hard to fake. That is to prevent cheating. Gold and silver were scarce so made good coins. Then printed currency was made hard to counterfeit. Trade with money is based on confidence in the money.

In an entirely different direction are the natural resources we take for granted - like air and water.

If you explain your question further in the comments, glad to respond.

Explanation:

Nature.

Real value equals nature which sustains all life.

This is indisputable & real value, nature & life are inseparable.

Nature is a singular compound billions years old recreative self-sustainable real value system of living organisms. Humans are a mere millions years old failing species of mammal.

Nature must and will inevitably be repaired, restored and expanded as the only source of REAL life sustaining value on the planet.

Value inequality concerns natures real life sustaining value and over billions of years through evolution nature has acheived some degree of balance. This has been disrupted by the human species using the failed fake value system of economics to create fake income inequality

Real value is not *emotional* or *symbolic* (wealth) and for mammals like we humans consists of life sustaining matter created solely by nature.

Fake “value“ or wealth is created by failed economics which creates fake income inequality that is used to manipulate the masses access to real value. Fake value is “shadow wealth” used by capitalists to control and manipulate access to natures real value.

Wealth is a fake value lien placed by the wealthy (capitalists) on natures real life sustaining value and is facilitated by economics and capitalism in particular.

Write the electronic configuration of Cr^2+ (z=24) and predict the number of electrons having n+1 value equal to 3
leonid [27]

Answer:

(a) Cr²⁺: 1s² 2s²2p⁶ 3s²3p⁶ 3d⁴; (b) eight  

Explanation:

(a) Electron configuration of Cr

(i). Locate chromium in the Periodic Table.

It's Element 24, so  in Period 4, Group 3.

(ii). Write its electron configuration

Remember that Cr is one of those exceptions to the Aufbau principle.

Instead of the predicted electron configuration of [Ar] 4s²3d⁴, we get the configuration [Ar] 4s3d⁵.

The reason is that this this configuration minimizes electron repulsion.

(b) Write the electron configuration for Cr²⁺.

Now, we must remove two electrons from a chromium atom.

The electron in the 4s orbital is removed first, because this orbital is further from the nucleus, making electrons easier to remove.

So, we remove the 4s electron, and  then a 3d electron.

The electron configuration of Cr²⁺ is

[Ar]3d⁴ or 1s² 2s²2p⁶ 3s²3p⁶ 3d⁴

(c). Electrons with n + l = 3

The orbitals with n + l = 3 are those covered by the third arrow down in the order of orbital energies:

2p (n = 2, l = 1) and 3s (n = 3, l = 0)

The 2p orbitals can hold six electrons, and the 3s orbital can hold two.

Both subshells are filled in a Cr²⁺ ion, so there are eight electrons

with n+ l = 3.

HELP Consider this equation...
Mashcka [7]

Answer:

it is not correct I have an answer for ''why''

Explanation:

You need to balance it

s= 2

0=2

S+30•2 --------> SO•3

2 2 2 2

S +3O•2-------->SO•2......MULTIPLY

2 4 2 4......LCM IS 4

2 1 2 1....DIVIDE BY 4

SO NOW WE GOT THE BALANCE NO. WE CAN PUT IT IN THE EQUATIONS.

2S+3O•2 -----> 2SO•3

now you can check the both sides its balances the correct answer is this

An electron can be added to halogen atom to force a halide ion with
Lilit [14]

An electron can be added to halogen atom to force a halide ion with 8 valence electrons

<h3>What is an atom?</h3>

An atom can be defined as the smallest part of an element which can take part in a chemical reaction.

However whenever, an electron is added to halogen atom to force a halide ion with 8 different valence electrons

So therefore; an electron can be added to halogen atom to force a halide ion with 8 valence electrons

The concentration of hydroxide ions is greater than the concentration of hydronium ions for acidic solutions.
Katena32 [7]

Answer:

True

Explanation:

It's true because the pH is a measure of how basic or acid a solution is. In an acidic medium, the pH scales goes from 0 to 7. While in a basic medium goes from 7 to 14. The lower the pH value of the most acid the solution is.

1. The expression pH = -log(molar concentration of hydronium) allow to calculate the pH of a solution.

2. On the other hand, the expression pOH = -log(molar concentration of hydroxide) allow to determine the pOH of a solution.

The values of pH and pOH always obey the following expression:

pH + pOH = 14

Thus if for instance the pH becomes smaller the pOH must become bigger in order to fulfill the equation. Which means that the concentration of hydronium ions is greater than the hydroxide concentration.

For example, in an acidic medium:

if pH= 3, pOH= 11

In this case the molar concentration of hydronium is 0,001M. And the molar concentration of hydroxide ions is just 0,00000000001M.
