Answer:  TRUE

Explanation:  Transition elements are those which have electrons in the d orbitals in their outermost valence shell. They are also known as d block elements.

Thus Copper, Iron, Nickel etc are d block elements because their electrons are in the d orbital as shown-

Copper (Cu) = [Ar] 3d10 4s1

Iron (Fe) = [Ar] 3d6 4s2

Nickel (Ni) = [Ar] 3d8 4s2

Thus as shown in the electronic configuration above, the given stateent is true.

If the half-life of Carbon-14 is 5700 years, how many years would it take a sample to decay from 1 gram to 31.3 mg
andrew-mc [135]

Answer:

28500 years

Explanation:

Applying,

A = A'(2^{x/y})............... Equation 1

Where A = Original mass of Carbon-14, A' = Final mass of carbon-14 after decaying, x = total time, y = half-life.

From the question,

Given: A = 1 g, A' = 31.3 mg = 0.0313 g, y = 5700 years.

Substitute these values into equation 1

1 = 0.0313(2^{x/5700})

2^{x/5700} = 1/0.0313

2^{x/5700}  = 31.95

2^{x/5700} ≈ 32

2^{x/5700} ≈ 2⁵

Equating the base and solve for x

x/5700 ≈ 5

x ≈ 5×5700

x ≈ 28500 years

What is the approximate mass of 72 cm3 of silver, if the density is 10.5 g/cm3?
77julia77 [94]

Answer:

<h3>The answer is 756 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of silver = 72 cm³

density = 10.5 g/cm³

We have

mass = 10.5 × 72

We have the final answer as

<h3>756 g</h3>

Hope this helps you
