Explanation:
Equimolar amounts of Cl2(g) and CO(g) are injected into an evacuated, rigid container, where they react according to the equation below. Cl2(g)+CO(g)⇄COCl2(g) ΔHrxn=−109kJ/molrxn (a) If 7.0 g of CO(g) is consumed in the reaction with excess Cl2(g), how many moles of COCl2(g) are produced? (b) Which element is oxidized in this reaction? Justify your answer in terms of oxidation numbers.
Answer:
0.25 moles of COCl₂ are been produced
The element that is oxidized is C, it changed the oxidation state from +2 in CO to +4 in phosgene.
Explanation:
Equilibrium reaction:
Cl₂(g) + CO(g) ⇄ COCl₂(g)
Let's convert the mass of CO to moles:
7g . 1mol /28g = 0.25 moles
As ratio is 1:1, we can say that 0.25 moles of COCl₂ are been produced.
1 mol of chlorine reacts to 1 mol of carbon monoxide in order to produce 1 mol of phosgene.
Chlorine is been reduced:
Cl₂ + 2e⁻ ⇄ 2Cl⁻
Change the oxidation state, from 0 (ground state) to -1. Oxidation state decreased.
Carbon is been oxidized.
In CO, carbon has +2 as oxidation state. In phosgene the oxidation state is +4. This oxidation state was increased, that's why it has oxidized.
The element that is oxidized is carbon whose oxidation number was increased from +2 to +4.
The equation of the reaction is;
Cl2(g) + CO(g) ⇄ COCl2(g)
We have been told that the chlorine gas is the reactant in excess hence the carbon monoxide is the limiting reactant.
Number of moles of CO = 7.0 g/28 g/mol = 0.25 moles
Since the reaction is 1:1, 0.25 moles of COCl2 is produced.
The element that is oxidized is carbon whose oxidation number was increased from +2 to +4.

Suppose a particle has 4 protons, 5 neutrons, and 2 electrons. What is its
charge?
Answer:
It's going to be a postive charge because although theres a lot more neutrons then the rest of them, neutrons are neutral, which won't have much of an effect to the charge of the atom. 4 protons has a larger proportion to the rest.

Describe how molecules in a solid are different from molecules in a gas.
Answer:
The difference between solid, liquid and gas can be drawn clearly on the following grounds:
A substance having structural rigidity and has a firm shape which cannot be changed easily is called solid. A water-like fluid, that flows freely, having a definite volume but no permanent shape, is called liquid. Gas refers to a state of matter, do not have any shape but conform to the shape of the container, completely, in which it is put in. While solids have certain shape and volume, liquids only have definite volume but not shape, gases neither have shape nor volume. The level of energy is highest in gases, medium in liquid and lowest in solids. The compression of solids is difficult, liquids are nearly incompressible, but gases can be easily compressed. Molecular arrangement of solids is regular and close, but liquids have irregular and sparse molecular arrangement and gases, too have random and more sparse arrangement of molecules. The molecular arrangement in solids is well organised. However, the layers of molecules slip and slide over one another, in the case of liquids. In contrast, the particles in gases are not at all organised, due to which the particles move randomly. When it comes to fluidity, solids cannot flow, however, liquids can flow and that also from the higher level to lower level. As against this gases flows in all directions. The spaces between the molecules and the kinetic energy are minimum in solids, medium in liquid and maximum in gases. So, the motion of molecules is negligible in solids, whereas in liquids, the erratic, random motion of molecules can be seen. Unlike gases, which have the free, constant and random motion of molecules. In solids, the particles are held tightly by strong intermolecular attraction, although in liquids the attraction between particles is intermediate. As against this, the particles are loosely held, because the intermolecular attraction is weak. The speed of sound is highest in solids, while the speed is a bit slower in liquids and minimum in gases. As solid have a definite shape and size, they do not require a container for storage. Liquids cannot be stored without a container. Conversely, for storing gases, a closed container is required.
Explanation:
Definition of Solid
By the term ‘solid’ we mean the type of matter which is rigid in structure and opposes the change in its shape and volume. The particles of a solid are tightly bound and well-arranged in a regular pattern, which does not allow the particles to move freely from one place to another. The particles continuously vibrate and twist, but there is no motion, as they are too close to each other. As the intermolecular attraction is maximum in solids, and because their shape is fixed, and the particles stay, where they are set. In addition to this, the compression of solid is very tough, as the spaces between molecules are already very less.
Definition of Liquid
A free flowing substance of constant volume having consistency is called as the liquid. It is a type of matter which do not have its shape but takes the shape of the vessel, in which it is held. It contains small particles, which are held tightly by intermolecular bonds. One of the unique property of liquid is surface tension, a phenomenon which makes the fluid possess the minimum surface area. The compression of liquid is a nearly difficult, due to less gap between particles. The particles are closely bound, but not as tightly as in the case of solid. Thus allowing the particles to move around and mix with one another.
Definition of Gas
Gas is described as a state of matter which diffuses freely in all directions and fills the entire space available, regardless of the quantity. It is made up of particle that does not have a certain shape and volume. The particles can be individual atoms or elemental molecules or compound molecules. In gases, the molecules are loosely held, and so there is a lot of space between molecules to move freely and constantly. Due to this characteristic, the gas has the ability to fill any container, as well as it can be easily compressed.
Answer:
the spaces between the molecules and the kinetic energy are minimum in solids, medium in liquid and maximum in gases. So, the motion of molecules is negligible in solids, whereas in liquids, the erratic, random motion of molecules can be seen. Unlike gases, which have the free, constant and random motion of molecules.

Knowing that a meteorologist is a scientist whose job requires special training, Leandra interviewed a local meteorologist for a science assignment. She wanted to find out what the important job duties of a meteorologist are. Choose the two that apply.
A. collect and analyze data to make predictions about the weather
B. guess what the weather will be and report it on television
C. carry out investigations of insects and how they affect the environment
D. use observations and technology to determine how global patterns affect weather
She was curious about the important job duties of a meteorologist, which include collecting and analysing data to make weather predictions and comparing weather data from various local, regional, and global sources.
What is the most important role a meteorologist has?Meteorologists perform both observation and investigation. They study maps, satellite data, and radar data to learn about the physical conditions of the atmosphere above them.In addition, they compare weather data from local, regional, and global sources.Many people believe that the person who gives the weather forecast on television is a meteorologist.However, television meteorologists make up a small percentage of all meteorologists.Meteorologists conduct research, teach, consult, and forecast. Meteorologists collect and analyse weather data in offices and research facilities. A weatherman, on the other hand, broadcasts live weather conditions, alerts, and forecasts.To learn more about Meteorologist, refer to:
