3. The cities listed below, from Chicago to Pittsburgh, lie in a roughly straight west to east line. Data on temperature, barometric pressure, and sky conditions for each city are shown in the table below. Use the data to explain what types of air masses are present and/or moving among these cities and how this accounts for the weather. What will Pittsburgh’s weather be like within the next 24 to 48 hours? City Temp (oF) Pressure (in.) Conditions
Chicago, IL 73 29.94 rising Clear
Indianapolis, IN 75 29.93 falling Partly cloudy
Columbus, OH 78 28.20 falling Light rain
Pittsburgh, PA 74 29.90 steady Mostly sunny

Explanation:

expect light rain in pittsburgh over the next 24 to 48 hours. The lower/falling pressures in cities to the west indicate that a low pressure system is moving from west to east toward pittsburgh. Low pressure systems are normally associated with precipitation. The fact that you do not see a big drop in temperature in the more western cities indicates the low pressure system is moving with a warm front, so only light rain would be expected. Heavy rains or more violent weather is only normally associated with cold fronts, where the warm air is pushed up and over a cold front rapidly. This rapidly rising air (convection) is what gives you heavier torrential rains, and other potentially severe weather conditions.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
