d1i1m1o1n [39]3 years ago
5 0

Answer:

Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)

Explanation:

Given:

Number of atom in (Ca) = 9 x 10¹⁶

Find:

Number mole of calcium (Ca)

Computation:

Number mole of calcium (Ca) = Number of atom in (Ca) / Avogadro's number

Number mole of calcium (Ca) = (9 x 10¹⁶) / (6.023 x 10²³)

Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)

The properties of substances can be used to put the into groups.

<h3>Grouping of substances</h3>

In chemistry, it is often necessary to put substances into groups based  on similarity in their properties. This is what led to the idea of a periodic table of elements.

Similarly, when we have unknown substances, we can group them according to the similarities in their properties.

Answer: The size of actual bed is 75 inches

Explanation: Scale refers to the ratio of the original dimension to the dimension on paper (miniaturised dimension). Since it is a ratio, it has no dimension.

Scale= original dimension/miniaturised dimension

Given that scale is 1:25

It means that every 1 inch on paper would correspond to 25 inches in reality.

The length of the model bed= 3 inches

Hence, the length of the original bed is 25*3 = 75 inches

Which of the elements below has the greatest electronegativity? <br> He <br> F <br> Fr <br> Rn
Law Incorporation [45]

F.
it's the greatest electron "hogger"
as you get closet to it, the stronger the electro negitivity.
He is halogen : they don't like to gain electrons. they are already stable.

Fr and Rn
are metals as far is I can remember. they would prefer losing electrons.

Which of the following is NOT a physical change?
andrey2020 [161]
Your answer is the last option, the explosion of fireworks. This is because all of the other options are physical changes because they don't change the substance, they only affect it in some way. However the explosion of a firework clearly changes a substance inside the initial 'rocket' into fireworks.

I hope this helps!
