True
the definition of matter is any substance that has mass and takes up space.
An element that reacts similarly to the element lithium (li) is sodium (Na).
A chemical element is a species of atoms that have a given variety of protons of their nuclei, consisting of the natural substance consisting most effective of that species. unlike chemical substances, chemical factors can not be damaged down into easier materials by way of any chemical reaction.
A element that can not be damaged down into less difficult materials via chemical means. Detail consists of atoms that have the same atomic variety, this is, every atom has an equal number of protons in its nucleus as all other atoms of that detail.
The three essential organizations on the Periodic desk are the metals, nonmetals, and metalloids. factors inside each institution have similar physical and chemical properties.

The answer:rock explanation:
Answer:
maltose
Explanation:
If we intend to determine the largest molecule, then we must look at the relative molecular mass of each molecule because the larger the molar mass, the larger the molecule.
Hydrogen =2 gmol-1
Carbon dioxide = 44 gmol-1
Ammonia = 17 gmol-1
Maltose= 342.3 g/mol
Hence maltose is the largest molecule among the options.
Answer:
Molecular formula = S₂O
₆
Explanation:
Given data:
Empirical formula = SO₃
Molecular formula = ?
Molecular mass = 152 g/mol
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 80 g/mol
n = 152 g/mol / 80 g/mol
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2(SO₃)
Molecular formula = S₂O
₆
