These are characteristics of viruses.
In an aqueous solution of lithium chloride (LiCl), the ions present in solution are lithium cations (Li+) and chloride anions (Cl-), and the water molecules (H2O).
Lithium chloride is an ionic salt, and therefore, fully dissociates or ionizes upon dissolution in water. From the chemical formula of lithium chloride, we can say that 1 lithium ion (positively-charged) only needs 1 chloride ion (negatively charged) to form the salt. Thus, upon dissociation of 1 molecule of LiCl, only 1 lithium ion, and 1 chloride ion form.
Water is a molecule formed by covalent bonds and <u>generally</u>, does not dissociate to form ions. However, if we consider the very minor contribution of the dissociation of water, hydroxide (OH-) ions and hydronium (H3O+) ions will also be present. However for water, very few molecules, only 1 in 550 million, are dissociated at any given time. Thus, we can consider the presence of the OH- and H3O+ ions to be negligible and just identify the molecular undissociated form of water to be present.
Answer:
4.09ₓ10²³ atoms are contained in 10g of C₃H₈
Explanation:
1 mol of C₃H₈ has 3 mol of carbon and 8 mol of hydrogen.
1 mol of C₃H₈ weighs 44 g
In 44 g of C₃H₈ we have 3 mol of C
In 10 g of C₃H₈ we'll have (10 . 3)/ 44 = 0.681 mol
1 mol of C has NA (6.02x10²³) particles
0.681 mol will have (0.681 . 6.02x10²³) = 4.09ₓ10²³ atoms
