Imagine the following scenario involving marbles as "radioactive isotopes".

Chemistry
1 answer:
sveta [45]3 years ago
8 0

Answer:

1 million years

Explanation:

The half life of a radioactive isotope refers to the time it takes for the radioactive isotope to decay to half of its original amount.

The half life of a radioactive isotope is independent of the amount of starting material. Hence, whether the amount of starting material is small or large, the half life of the substance remains the same.

Hence the half life of 2 green marbles and 500,000 green marbles is 1 million years.

Does NH3 dissolve in acetone?
Sladkaya [172]
Acetone will react with ammonia. Acetone will act as an Lewis Acid and ammonia will act as a Lewis Base in this situation. The nitrogen in NH3 is very reactive because of its lone pair of electrons(The nitrogen is delta -ve), so it will attack the carbon cation center of the acetone (which is delta +ve).

Which is the term for an ion that has more protons than electrons
murzikaleks [220]

Answer:

The correct answer is cation. See the explanation below, please.

Explanation:

An atom with a net charge, either positive or negative, is called an ion. In the event that an atom loses an electron (or more), that is, it will have more protons than electrons, and its net charge will be positive, it will be called cation. In the opposite direction, if an atom gains electrons, it will have a negative net charge, called anion.

What is the molecular formula of each compound?<br> (c) Empirical formula HgCl (m = 5 472.1 g/mol)
beks73 [17]

The molecular formula of HgCl (m = 5 472.1 g/mol) is Hg2Cl4.

The molecular formula is an expression that defines the number of atoms of each element in one molecule of a compound. It shows the actual number of each atom in a molecule.

<h3>Molecular formula: What is it?</h3>

A chemical formula is a way to communicate information in chemistry about the proportions of atoms that make up a specific chemical compound or molecule. Chemical element symbols, numbers, and occasionally other symbols like parentheses, dashes, brackets, commas, and plus and minus signs are used to represent the chemical elements.

A molecule's molecular formula reveals which atoms and how many of each kind are included within it. No subscript is used if there is just one atom of a certain kind. A subscript is added to the symbol for an atom if it contains two or more of a certain type of atom.
