Answer and Explanation:
Metals are lustrous (shiny), malleable (that means that can be hammered) and ductile. They are usually solid at room temperature (except mercury which is liquid). They are good conductors of heat and electricity. They are made of metallic bonds. Examples: iron (Fe), silver (Ag).
Ionic compounds are hard and usually brittle. They form crystals (solid at room temperature) and they have high melting points. They only conduct electricity when are dissolved in water. They are made of ionic bonds Examples: sodium chloride (NaCl), magnesium oxide (MgO).
Molecular compounds are gases, liquids or low-melting solids. They are poor conductors of heat and electricity. They have low melting and boiling points. They are made of covalent bonds. For example: methane (CH₄) and ozone (O₃).
A. Potassium oxide
B. Calcium chloride
C. Magnesium nitride
D. Sodium hypochlorite
E. Potassium nitrate
Answer:
Rate will increase by 3 times
Explanation:
According to the law of mass action:-
The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.
Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.
The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.
Given that:- Rate law = ![k[NO_2][CO]](https://tex.z-dn.net/?f=k%5BNO_2%5D%5BCO%5D)
Thus, if the pressure is increased from 0.2 atm to 0.6 atm, means 3 times, rate will also increases 3 times.
A. Because that is basically referring to riots. Attacking the oppositions personality instead of thinking logically about the actual problem.
matching element is as below
calcium -ca
iron- Fe
nickel=Ni
copper-Cu
gold- Au
<h3><u>explanation</u></h3>
symbols is a code for a chemical element. some element are given symbols from their first two letters for example calcium symbol Ca is from first two letters. some symbols are from latin words example symbol Au for gold is from a latin word Aurum
