Answer : The area of the field is, 480000cm^2

Explanation : Given,

Length of rectangular field = 8.0 m = 800 cm

Width of rectangular field = 6.0 m = 600 cm

Conversion used : (1 m = 100 cm)

Formula used :

Area = Length × Width

Now put all the given values in this formula, we get the area of the field.

Area = 800 cm × 600 cm

Area = 480000m^2

Therefore the area of the field is, 480000cm^2

<h3>Answer:</h3>

CuO(s) + H₂(g) →  Cu(s) + H₂O(l)

<h3>Explanation:</h3>
  • Assuming the reaction is the reduction of CuO by H₂
  • Then the balanced equation for the reaction is;

CuO(s) + H₂(g) →  Cu(s) + H₂O(l)

  • The equation shows the reducing property of hydrogen gas, such that hydrogen reduces metal oxides such as copper(ii)oxide to the respective metals.
  • The law of conservation requires chemical equations to be balanced so as the mass of reactants will be equal to that of products.
  • In this case; there is 1 copper atom, 1 oxygen atom and 2 hydrogen atoms on both side of the equation and thus the equation is balanced.

Answer:

Q = 2.60 • 10^{3} J

Explanation:

Our specific heat capacity equation is:

Q = mC∆T

Q is the energy in joules.

m is the mass of the substance.

∆T is the temperature chance.

Let's plug in what we know.

  • We have 76.0 g of octane
  • The specific heat capacity of octane is 2.22 J/(g•K)
  • The temperature increases from 10.6º to 26.0º (a 15.4º increase)

Q = 76.0(2.22)(15.4)

Multiply.

Q = 2598.288

We want three significant figures.

Q = 2.60 • 10^{3}

or

Q = 2590 J

Hope this helps!
