What is named first the cation or anion? correct answer: Cation How many Ligands are in [Cr(NH3)6](NO3)3 correct answer: 6 How many Ligands are in K[Au(OH)4] correct answer: 4 Oxidation number of the metal in K[Au(OH)4]? correct answer: +3 explanation: hydroxide has a charge of -1, since there are a total of 4 hydroxides the total (-) charge is -4. The charge of K is +1. Therefore the charge of Au must be +3. +4 + (-4)=0 Within a complex ion ligands are named in _____________ ord...

mass of an electron - correct answer 1/2000th of a proton relative charge and relative mass of a proton, neutron, and electron - correct answer proton: charge=+1 mass=1 neutron: charge=0 mass=1 electron: charge=-1 mass=1/2000th atomic number - correct answer the number of protons in the nucleus of an atom mass number - correct answer the sum of the number of neutrons and protons in an atomic nucleus isotopes - correct answer atoms of the same element with a different mass number an...

Mole concept - correct answer mole is the chemist's counting unit. One mole of any substance- element or compound- consists of 6.02 X 10²³ formula units of the substance. Conversion of moles - correct answer number of moles = mass x molar mass N=m (g) M (g/mol-1) Molecular formula - correct answer Molecular formula is the number of each type of atom in the smallest viable unit of the substance. Atomic Mass - correct answer This is the mass of the atom of a specific element. It is ...

Bases - ANS-A substance which accepts hydrogen ions, or protons. They are also called proton acceptors. Both metal oxides and metal hydroxides can act as these.

acids and bases lab what are acids and bases according to the bronsted lowry theorem - correct answer acids are hydrogen ion donors, bases are hydrogen ion acceptors. what does the bronsted lowry theorem state - correct answer each acid has corresponding base, called the conjugate base, that is formed when acid loses hydrogen ion. what is the equation for the bronsted lowry theorem - correct answer HA + H₂O → H₃O⁺ + A⁻ acid ← hydronium conjugate base what will a bronsted l...

19.1 IntroductIon Qualitative analysis deals with the identification of inorganic substance or a mixture of substances. Gen- erally inorganic substances dissociate in water to give positive and negative ions. The positive ions are also called as basic radicals and the negative ions are called as acid radicals. The tests carried for the identification of different ions can be divided into three types 1. Preliminary tests 2. Tests for anions 3. Tests for cations 19.2 PrelImInary tests ...
