Which of the following functional groups acts most like an acid in water? A) carboxyl B) amino C) carbonyl D) hydroxyl.
Anestetic [448]

Answer : A - carboxyl group.


The carbon in the carboxyl group is bonded to a hydroxyl group and also it is double bonded to an oxygen group.


The carboxyl group when it is dissolved in a solution donates it's hydrogen ion(H+ ion). When it is dissolved in water, the carboxyl group loses its H+ ion to form negatively charged ion.


RCOOH + H2O⇄RCOO- + H3O+


Thus the carboxyl group act as an acid when dissolved in water.

Now describe the properties of the compound you picked(gold). Compare the properties of the compound with the properties of the
alexgriva [62]

Explanation:

Gold conducts heat and electricity. ...

Gold is ductile: It can be drawn out into the thinnest wire. ...

Gold is highly reflective of heat and light. ...

Gold is prized for its beauty. ...

Gold is malleable, so it can be flattened into extremely thin sheets.

on the other hand Gold consist of copper

Key Properties of Copper Alloys

Excellent heat conductivity.

Excellent electrical conductivity.

Good corrosion resistance.

Good biofouling resistance.

Good machinability.

Retention of mechanical and electrical properties at cryogenic temperatures.

Non-magnetic.

so the difference is that copper is less expensive and not priced with its beauty

If a particular ore contains 58.6 % calcium phosphate, what minimum mass of the ore must be processed to obtain 1.00 kg of phosp
rjkz [21]
Answer is: mass of the ore is 8.54kg.<span>

</span>ω(Ca₃(PO₄)₂ - calcium phosphate) = 58.6% ÷ 100% = 0.586.
m(P) = 1.00 kg · 1000 g/kg.
m(P) = 1000 g.
In one molecule of calcium phosphate there are two phosphorus atoms:
M(Ca₃(PO₄)₂) = 310.18 g/mol.
M(P) = 30.97 g/mol.
For one kilogram of phosphorus, we need:
M(Ca₃(PO₄)₂) : 2M(P) = m(Ca₃(PO₄)₂) : m(P).
310.18 g/mol : 61.94 g/mol = m(Ca₃(PO₄)₂) : 1000 g.
m(Ca₃(PO₄)₂) = 5007.75 g ÷ 1000 g/kg = 5.007 kg.
Mass of ore find from proportion:
m(Ca₃(PO₄)₂) : m(ore) = 56% : 100%.
m(ore) = 100% · 5.007 kg ÷ 58.6%.
m(ore) = 8.54kg.

Describe the pattern that thermal energy follows as it moves
mars1129 [50]
When you bring two objects of different temperature together, energy will always be transferred from the hotter to the cooler object.  The objects will exchange thermal energy, until thermal equilibrium<span> is reached, i.e. until their temperatures are equal.  We say that </span>heat<span>flows from the hotter to the cooler object.  </span><span>Heat is energy on the move.</span> <span> 
</span>Units of heat are units of energy.  The SI unit of energy is Joule.  Other often encountered units of energy are 1 Cal = 1 kcal = 4186 J, 1 cal = 4.186 J, 1 Btu = 1054 J.

Without an external agent doing work, heat will always flow from a hotter to a cooler object.  Two objects of different temperature always interact.  There are three different ways for heat to flow from one object to another.  They are conduction, convection, and radiation.
