The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13–18; the transition metals in the columns labeled 3–12; and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row ...
atoms are made of 3 types of subatomic particles ; protons, neutrons and electrons.
Atomic number is the number of protons. Atomic number is characteristic for the element. So atoms of the same element will have the same number of protons.
mass number is the sum of protons and neutrons
Isotopes are atoms of the same element with different mass numbers. So since they are the same element the number of protons will be the same. But different mass numbers means number of neutrons will be different
therefore the three known forms of hydrogen are called A. isotopes
each of these forms will have the same number of A. protons
but different numbers of B. neutrons in their nuclei
Hello!
Order of magnitude of a measure is an estimate of the base power 10 closest to a given measure.
The scientific notation (N) of 0.000000000333 (x), being (number of decimal places) y, knowing that the scientific notation according to the rule of scientific notation, before the comma can only have the numbers 1 to 9, let's see:
note: Moved 10 decimal places to the right negatively
I Hope this helps, greetings ... DexteR! =)
Answer:
False, we cannot made 16 muffins from 3 eggs.
Explanation:
2 cups flour + 1 egg + 3 oz blueberries → 4 muffins
According top recipe, 2 cups of flour, 1 egg and 3 oz of blueberries are made into batter to give 4 muffins.
Then 16 muffins will made from:
For each muffin we need =
Then for 16 muffins we will need:
4 eggs will be required to make 16 muffins
From 1 egg we can made 4 muffins
Then from 3 eggs we can made = 3 × 4 muffins = 12 muffins
12 muffins will made from 3 eggs.
We cannot make 16 muffins from 3 eggs.
Besides nylon, HCl is formed from the reaction of adipoyl chloride and 1,6- diaminohexane , but HCl is the byproduct molecule.
<h3>What is formed when adipoyl chloride and 1,6-diaminohexane reacts with each other and what are the by products?</h3>
- Adipoyl chloride is the monomer and hexamethylinediamine is also the monomer which reacts together to form polymer.
- The polymer formed is named nylon6,6 which is a co polymer and nylon 6,6 find its use in various other activities of life.
- Nylon6,6 is a copolymer since the participation of two monomers , and not a single monomer undergoing decomposition.
- Nylon6,6 is formed with an elimination of small molecule of HCl which is considered to be a by product .
- It is formed by a condensation reaction and hence HCl is the product formed from the reaction of adipoyl chloride and 1,6- diaminohexane.
