Answer:
Magnesium - Metallic lattice
Nitrogen - Molecules
Lithium - Metallic lattice
Potassium - Metallic lattice
Explanation:
Metals exist in metallic lattices. In this lattice, metal ions are held together with a sea of electrons by strong electrostatic forces.
All metals possess this metallic lattice, hence; potassium, lithium and magnesium all consist of metal lattices.
Nitrogen is a nonmetal and consists of molecules of N2.
Answer:
3 NADH molecules are made from each molecule of acetyl CoA through the Krebs Cycle.
Explanation:
First, 1 NADH is produced from each carbon lost from the 6-carbon citric acid (2 NADH total). Lastly, 1 additional NADH is made from the transformation of malate into oxaloacetic acid (acceptor molecule for acetyl CoA).
The smaller number is the number of protons, and the greater number is the mass.
Answer:
96 g of O
Explanation:
Mg(OH)₂ → Magnesium hydroxide
Molar mass → 24.3g/mol . 1 + 16g/mol . 2 + 1g/mol . 2 = 58.3 g/mol
We determine the moles of hydroxide → 175 g . 1mol/58.3g = 3 moles
Let's make some rule of three:
In 100 g of compound we have 54.87 g of O
In 58.3 g of compound we may have (58.3 . 54.87) / 100 = 32 g
So, 1 mol of hydroxide has 32 g of oxygen
3 moles of hyroxide may have (3 .32)/1 = 96 g of O
Answer:
I cant really do that but I will give u the material to make a table
Explanation:
Solid is the state of matter in which the substance has a definite shape and volume. Liquid is the state in which the substance takes the shape of its container but has a definite volume.Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.
