Answer:

C, E, H, A, B, F, K, D, L, G, J, I.

Explanation:

Hello,

In this case we are dating each layer based on its deepness as the deeper the layer is, the farther back in time it is (older). In such a way, the youngest layer is C and henceforth by going down, we find older and older layers no matter if the layer is horizontal or diagonal, we just go down by straight line, therefore, from youngest to oldest, the order turn out into:

C, E, H, A, B, F, K, D, L, G, J, I.

Best regards.

Answer:

"2.48 mole" of H₂ are formed. A further explanation is provided below.

Explanation:

The given values are:

Mole of Al,

= 3.22 mole

Mole of HBr,

= 4.96 mole

Now,

(a)

The number of mole of H₂ are:

⇒  \frac{Mole \ of \ H_2}{3} =\frac{Mole \ of HBr}{6}

or,

⇒  Mole \ of \ H_2=\frac{1}{2}\times Mole \ of \ HBr

⇒                      =\frac{1}{2}\times 4.96

⇒                      =2.48 \ mole

(b)

The limiting reactant is:

= HBr

(c)

The excess reactant is:

= Al

What substance is produced at the cathode during the electrolysis of a mixture of molten calcium bromide, cabr2(l), and molten m
Afina-wow [57]
<span>The substance that is produced at the cathode during the electrolysis of a mixture of molten calcium bromide, cabr2(I), and molten magnesium iodide, mgi2(I), can be expressed as Ca2+ + 2eâ’ --> Ca. At the anode, the substance can be expressed as 2Brâ’ â’ 2eâ’ --> Br2. At the cathode for magnesium iodide can be expressed as Mg2+ + 2 eâ’ --> Mg, and 2 Iâ’ â’ 2 eâ’ --> I2 at the anode.</span>

If the length of one side of a square is 12.0 m, what is the perimeter of the square? Express the perimeter with the appropriate
Cerrena [4.2K]

The perimeter of a square whose length is 12.0 m is 48 cm.

<h2>Further Explanation </h2><h3>Area </h3>
  • Area is a measure of how much space is occupied by a given shape.
  • Area of a substance is determined by the type of shape in question.

For example;

  • Area of a rectangle is given by; Length multiplied by width
  • Area of a triangle = 1/2 x base x height
  • Area of a circle = πr². where r is the radius of a circle,
  • Area of a square = S², Where s is the side of the square.etc.
<h3>Perimeter </h3>
  • Perimeter is defined as the distance along a two dimension shape.  Perimeter of different shapes is given by different formulas

For example;

  • The perimeter of a rectangle = 2(length+width)
  • The perimeter of a triangle = a+b+c; where a, b and c are the sides of the triangle. etc.

In this case;

We are given one side of a square as 12.0 cm

But Perimeter of a square is given by; 4 × s

Thus; Perimeter = 4 × 12 units

                           = 48 units
