Olegator [25]3 years ago

Answer:

Two physical properties that would allow differentiation between copper, lead and iron shot are - <u>Color</u> and <u>Density </u>

<u>COPPER -</u> <u>Color -</u> Copper has a<u> reddish brown color .</u>

                <u> Density -</u> Density of copper is<u> 8.96 </u>g/cm^{3}<u></u>

<u>LEAD </u>- <u>Color -</u> Lead is <u>grey</u> in color.

           <u>Density</u> - Density of Lead is <u>11.34</u>g/cm^{3}<u />

<u>IRON SHOT -</u> <u>Color-</u>  Iron shot is in <u>grey color with extra shine .</u>

                     <u>  Density -</u> Density of iron shot is <u>10.49 </u>g/cm^{3}

Explanation:

COPPER- Copper (Cu) is a reddish, highly ductile metal that belongs to Group 11 (Ib) of the periodic table and is a particularly excellent conductor of electricity and heat. Copper is found in nature in its free metallic state.

LEAD- Lead (Pb) is a soft, silvery white or grayish metal in Periodic Group 14 (IVa). Lead is a weak conductor of electricity and is very malleable, ductile, and thick. Lead, which has been known since antiquity and is considered the oldest of metals by alchemists, is extremely durable and corrosion-resistant, as evidenced by the continued use of lead water pipes constructed by the ancient Romans.

IRON SHOT - Small round iron balls used as projectiles are known as iron shot. Balance scales are used with simple weights. Iron balls are used in the shot put competition.

<u>Hence , the differentiation is mentioned in the above answer.</u>

Sergio [31]

<u>Answer:</u> The molecular balanced equation is written below

<u>Explanation:</u>

A molecular equation is defined as the chemical equation in which the ionic compounds are written as molecules rather than component ions.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the decomposition of bromine trifluoride follows:

2BrF_3\rightarrow Br_2+3F_2

By Stoichiometry of the reaction:

2 moles of bromine trifluoride produces 1 mole of bromine gas and 3 moles of fluorine gas

Hence, the molecular balanced equation is written above.

One way to measure temperature in some applications is to monitor the gas pressure in a rigid, closed container. What is the tem
julia-pushkina [17]

Answer:

296.43 K is the temperature of a vessel when pressure reads 1.250 atm.

Explanation:

At STP, when pressure is 1.000 atm the value of temperature is 273,15 K.

If the pressure at temperature T reads as 1.250 atm.

P_1=1.000 atm, T_1=298.15K

P_2=1.250 atm,T_2=?

Applying Gay Lussac's law:

\frac{P_1}{T_1}=\frac{P_2}{T_2} (At constant volume)

\frac{1.000 atm}{273.15 K}=\frac{1.250 atm}{T_2}

T_2=296.43 K

296.43 K is the temperature of a vessel when pressure reads 1.250 atm.

Ozone (O 3) in the atmosphere can react with nitric oxide (NO): O 3(g) + NO(g) → NO 2(g) + O 2(g). Calculate the ΔG° for this re
Mandarinka [93]

Answer:

ΔG°  = 1022. 8 kJ

Explanation:

ΔH° = –199 kJ/mol

ΔS° = –4.1 J/K·mol

T = 25°C = 25 + 273 = 298K (Converting to kelvin temperature)

ΔG° = ?

The relationship between these varriables are;

ΔG° = ΔH°  - TΔS°

ΔG° = –199 - 298 (–4.1)

ΔG° = -199 + 1221.8

ΔG°  = 1022. 8 kJ

What happens to an atom in a liquid as it freezes?
siniylev [52]
When a liquid is frozen, the atoms in the liquid slow their movement due to lack of energy so the substance becomes hard.
