<h2>Hello!</h2>
The answer is: 
<h2>Why?</h2>
First, we need to look for the K molecular mass:
Also, we need to remember that 1 mol of a compound or element is equal to 
of that compound.
From the statement, we are asked to calculate how many atoms of K are present in 195,49 of K.
So, doing the calculations, we have:
So, we have atoms of K in 195,49 grams of K.
Have a nice day!
Answer:
5 × 10⁵ molecules (500,000 molecules)
Explanation:
Step 1: Convert 3 × 10⁻¹⁶ g to moles
We will use the molar mass of TCDD (321.97 g/mol).
3 × 10⁻¹⁶ g × 1 mol/321.97 g = 9 × 10⁻¹⁹ mol
Step 2: Convert 9 × 10⁻¹⁹ mol to molecules
The required conversion factor is Avogadro's number (6.02 × 10²³ molecules/mol).
9 × 10⁻¹⁹ mol × 6.02 × 10²³ molecules/1 mol = 5 × 10⁵ molecules
Answer:
The answer lies with carbon's unique properties. Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen
Explanation:
Answer:
Explanation:
According to the experiment, the very nucleus of the atom is conformed by protons and neutrons, whereas electrons are diminute and have low mass in comparisson to protons and neutrons. So then, the nucleus accounts for the size and the mass of the atoms.
Answer:
Grignard reagent is a chemical compound having a halogen group along with magnesium and organic group.
Explanation:
When cyclopentanol reacts with thiogyl chloride, it gives chlorocyclopentane as the product which on further reaction with magnesium metal gives Grigmard reagent as the main product.
A Grignard reagent is a chemical compound which have the chemical formula of R−Mg−X. Here, R is an organic group, Mg is magnesium and X is halogen. The organic group may be aryl or alkyl.
The reaction and the final product is given below at the attachment.
