Answer:It has the lowest effective nuclear charge of the four new elements.
Structure of an Amino Acid. Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH 2), a carboxyl group (COOH), and to a hydrogen atom.
Answer:
4.4 mol.
Explanation:
Hello!
In this case, since the formula for calculating the molarity is:

Whereas n stands for moles and V for the volume in liters; we can solve for n as shown below when we are given the volume and the molarity:

Thus, we plug in the given data to obtain:

Best regards!
Answer:
B. electron
Explanation:
B. electron
electron is a negatively charged particle
proton is a positively charged particle
Answer:
atoms of hydrogen are there in
35.0 grams of hydrogen gas.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:
1 mole of hydrogen
=
atoms
17.5 mole of hydrogen
=
atoms
There are
atoms of hydrogen are there in
35.0 grams of hydrogen gas.
