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

Chemistry

gayaneshka [121]2 years ago

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.

When 70.4 g of benzamide (C7H7NO) are dissolved in 850. g of a certain mystery liquid X, the freezing point of the solution is 2
Arlecino [84]

Answer:

1.62

Explanation:

From the given information:

number of moles of benzamide  =\dfrac{70.4 \ g}{121.14 \ g/mol}

= 0.58 mole

The molality = \dfrac{mass \ of \ solute (i.e. \ benzamide )}{mass \ of \ solvent  }

= \dfrac{0.58 }{0.85 }

= 0.6837

Using the formula:

\mathbf {dT  = l   \times  k_f  \times m}

where;

dT = freezing point = 27

l = Van't Hoff factor = 1

kf = freezing constant of the solvent

∴

2.7 °C = 1 × kf ×  0.6837 m

kf = 2.7 °C/ 0.6837m

kf = 3.949 °C/m

number of moles of NH4Cl = \dfrac{70.4 \ g}{53.491 \  g /mol}

= 1.316 mol

The molality = \dfrac{1.316 \ mol}{0.85 \ kg}

= 1.5484

Thus;

the above kf value is used in determining the  Van't Hoff factor for  NH4Cl

i.e.

9.9 = l × 3.949 × 1.5484 m

l = \dfrac{9.9}{3.949 \times 1.5484 \ m}

l = 1.62

Which of the following statements about trends in solubility is accurate?
Kipish [7]

"The solubility of gases decreases as temperature rises" statements about trends in solubility is accurate.

<u>Option: D</u>

<u>Explanation:</u>

A substance's solubility is the quantity of that component that is needed at a defined degree of temperature to produce a saturated solution in any set quantity of solvent. Some compounds like hydrochloric acid, ammonia, etc  have solubility that reduces with rising temperature. They are both standard-pressure gases.

When heating a solvent with a gas absorbed in it, both the solvent and the solute spike in the kinetic energy.When the gaseous solute's kinetic energy rises, the molecules have a higher propensity to overcome the solvent molecules' connection and migrate to the gas phase. Thus, a gas's solubility reduces with rising temperature.

A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HNO3 in a coffee cup calorimeter. If both solutions
Mars2501 [29]

Answer:

Qm  = -55.8Kj/mole

Explanation:

NaOH(aq) + HNO₃(aq) => NaNO₃(aq) + H₂O(l)

Qm = (mc∆T)water /moles acid

Given => 100ml(0.300M) NaOH(aq) + 100ml(0.300M)HNO₃(aq)

=> 0.03mole NaOH(aq) + 0.03mole HNO₃(aq)

=> 0.03mole NaNO₃(aq) + 0.03mole H₂O(l)

ΔH⁰rxn = [(200ml)(1.00cal/g∙°C)(37 – 35)°C]water / 0.03mole HNO₃

= 13,333 cal/mole x 4.184J/cal = 55,787J/mol = 55.8Kj/mole (exothermic)*

Heat of reactions comes from formation of H-Oxy bonds on formation of water of reaction and heats the 200ml of solvent water from 35⁰C to 37⁰C.
