Answer:
See explanation.
Explanation:
Carbonate and Nitrate: during double resonance the double bond revolves around each oxygen. This creates an atmosphere equal to each O-C-O link, then all 1200.
Phosgene: being that the atmosphere changes for each atom the bond angle should be 120, but a deviation occurs, since oxygen is more electronegative than Cl and O, so it is doubly linked. The Cl-C-O bond increases because the O and Cl repel each other, and a 124.3 bond angle is created between Cl-C-O, decreasing the Cl-C-Cl bond angle to 111.4 degrees.
See the result in the attached graph.

THE RAIN OR PRECIPITATION WHICH IS ACIDIC IN NATURE IS CALLED ACID RAIN. WET AND DRY DEPOSITIONS ARE THE TWO TYPES OF ACID RAINS.UNIVERSAL INDICATOR IS USED TO DETERMINE COLOUR CHANGE AND HOW ACIDIC AND BASIC IS THE SOLUTION.
Explanation:
The rain which is acidic in nature is called acid rain. It is a precipitated form that contains acidic components such as sulphuric acid or nitric acid. The acid rain is of two types i.)wet deposition ii.)dry deposition
Wet deposition means the acid rain will be of wet form. Dry deposition means the acid rain contains dust,gasses, rain, snow, fog and hail.
Sulphuric dioxide and nitric oxides mix with water, oxygen and other chemicals in the air and becomes sulphuric acid and nitric acids that mix with precipitation and fall on to the ground.the precipitation is said to be acidic when its ph is below 5.2.
The different polyatomic ions that form acids are H+ and SO4-2 and H+ cation and NO3- anions.
A universal indicator is a mixture of indicators which show a colour change in a solution, which interprets how acidic or basic a solution is. A universal indicator can be in paper form or present in a form of a solution.The colours from yellow to red indicate an acidic solution, colours blue to violet indicate bases and green colour indicates that a solution is neutral.
This item can be answered by using the concept of material balance. The amount of substance used for the reaction should be the same before and after the reaction occurred.
Amount of reactants = 3.55 grams + 4.60 grams = 8.15 grams
We are also given that the amount of product accounted for is only 6.25 grams, this entails that not all copper was reacted. Subtracting this value from 8.15 g will give us an answer of 1.9 grams.
Answer: 1.9 g of copper
