Answer:  Ductility

Explanation:  Copper is used in wiring because -

1. It is a metal which is a good conductor of heat and electricity due to the motion of the free electrons.

2. It has high ductility and malleability.

Ductility is the feature in which the metals can be stretched in to thin wires and Malleability is the feature n which the metals can be made into thin sheets.

3. These wires can withdraw a wide load of electric current.

If wind is eroding an area at a rate of 2 mm per year and depositing it in a smaller area at a rate of 7 mm per year, how much l
amid [387]

Answer:

After 2000 years, the first after will be 4m lower.

After 2000 years, the second area will be 14m higher.

Explanation:

From the given information:

At the first area:

if the wind is eroding at 2 mm/year, then after 2000 years; we have:

2 mm/year × 2000 year = 4000 mm

4000 mm to meters, we have:

=4000 \ mm \times \dfrac{1 \ m}{ 1000 \ mm}

= 4 m lower

At the second smaller area:

Given that the wind is depositing it at the rate of 7 mm per year;

Then:

7 mm/year × 2000 year = 14000 mm

=14000 \ mm \times \dfrac{1 \ m}{ 1000 \ mm}

=14 m higher

A quantity of liquid methanol, CH3OH, is introduced intoa rigid 3.00-L vessel, the vessel is sealed, and the temperature israise
Tom [10]

Answer:

74,3 grams is the mass of methanol that was initially introduced into the vessel

Explanation:

                         CH3OH(g)        ---->          1 CO(g)    +   2 H2(g)

initial:             Idk what i have (X)                    -                    -

react:                initial - react                        react              react

equilibrium:    A concentration                  A conc.         0.426 M

                         in equilibrum                      in eq      

                         

See that in equilibrium are formed 2 moles of H2 with this concentration, 0,426M and you form 1 mol of CO, so the moles that are formed of H2 are the double of CO, because stoychiometry.

                            CH3OH(g)        ---->          1 CO(g)    +   2 H2(g)

initial:                 Idk what i have (X)                   -                    -

react:                    initial - react                     react              react

equilibrium:        A conc. in eq                     0,213 M         0.426 M

So we have concentrations of products in equilibrium, and we have Kc, now we can find concentration of reactants in equilibrium

Kc = ([CO] . [H2]*2) / [CH3OH]

6,9X10*-2 = (0,213 . 0,426*2) / [CH3OH]

[CH3OH] = (0,213 . 0,426*2) / 6,9X10*-2

[CH3OH] = 0,560 M

You know that 1 mol which reacted has this concentration in equilibrium, 0,213 M so I can know what's my initial concentration of reactive

Initial - react = equilibrium

initial - 0,213M = 0,560M ---> Initial = 0,773 M

0,773M is initial concentration of CH3OH, but this is molarity, (moles in 1L). My volume is 3 L so

1 L _____ 0,773 moles

3 L _____  3L . 0,773moles = 2,319 (the moles that i used)

Molar mass CH3OH = 32.06 g/m

Moles . molar mass = grams ---> 2,319 moles . 32,06 g/m  = 74,3 g

What chemical reaction occurs when one element replaces another compound
S_A_V [24]
<h2>The chemical reaction occurs when one element replaces another compound.</h2>

Explanation:

Chemical reaction : It is the reaction in which two or more substances react to form some new substance .

Like : Burning of fuel etc

We have different types of reactions occurring  around us like:

  • Combination reaction
  • Decomposition reaction
  • Displacement reaction
  • Double decomposition reaction
  • Redox reaction

Displacement reaction

it is a reaction between element and a compound in which more reactive element displaces less reactive from its compound  

i.E  CuSO₄  +  Zn --> ZnSO₄ + Cu

(copper sulphate )      (Zinc sulphate )

In this we follow reactivity series and accordingly we come to know whether the reaction will occur or not .

Like if the above asked reaction is modified as this :

ZnSO₄   +  Cu ------> No reaction

This is because copper being less reactive than Zn cant displace zinc .Hence , no reaction occur .
