Living organisms all contain fats that are called lipids<span>. Lipids are long non polar biologic molecules, formed by functional blocks called fatty acids.Lipids are responsible for the storage of energy and make up the structure of the cell membranes. Fatty acids are long chain carboxilic acids.</span>
1 mole has 6.023*10^23 molecules
0.6*6.023*10^23=3.6138*10^23 molecules
Answer:
0.05 L
Explanation:
The density is the mass that is occuping a volume, or the mass in each unity of the volume, so to calculate the volume, we just divide the mass by the density:
V = 55.0/1.10
V = 50.0 cm³
Knowing that 1 cm³ = 0.001 L, so V = 0.05 L.
Answer: Proton
Explanation:
hydrogen ion is the basis of the pH scale. H:– = Hydride. Hydride is a hydrogen atom which has an extra electron.
Answer: hot
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and the system will be cold and surroundings will be hot.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and the system will be hot and surroundings will be cold.
As heat is absorbed, the reaction is endothermic and the system will feel hot.
