This is not a good idea u never know what the chemicals could do when in contact with metal or pipes or even water. always ask your chem teacher and make sure they tell u before. also alert them if this has happened because they can alert the school and act as needed

Answer:

That's a major lab mistake! Never pour chemicals in sink unless otherwise stated by the lab instructor. They should go in a properly labelled waste jar or similar container. Apparatus should not be left in sink, it should be washed and cleaned, and returned to where it came from.

What is the partial pressure of carbon dioxide in a container that contains 3.63 mol of oxygen, 1.49 mol of nitrogen, and 4.49 m
lana66690 [7]

Answer:

Partial pressure of CO₂ is 406.9 mmHg

Explanation:

To solve the question we should apply the concept of the mole fraction.

Mole fraction = Moles of gas / Total moles

We have the total moles of the mixture, if we have the moles for each gas inside. (3.63 moles of O₂, 1.49 moles of N₂ and 4.49 moles of CO₂)

Total moles = 3.63 mol O₂ + 1.49 mol N₂ + 4.49 mol CO₂ = 9.61 moles

To determiine the partial pressure of CO₂ we apply

Mole fraction of CO₂ → mol of CO₂ / Total moles = P. pressure CO₂ / Total P

Partial pressure of CO₂ = (mol of CO₂ / Total moles) . Total pressure

We replace values: (4.49 moles / 9.61 moles) . 871 mmHg = 406.9 mmHg

DaniilM [7]
<span>Africa was more south and west and South America was more south and east of their current positions. I would say this would be because because South America and Africa used to be together in Gondwanaland millions of years ago and then apparently drifted apart as Wegener thought and then with the advent of plate tectonics it became apparent that the mid-Atlantic ridge runs between them and due to spreading along it Africa and S America got separated.</span>

Write the value represented by 4.5x10-6 g
monitta

the value represented by 4.5x10-6 g is 0.0000045 g it is a representation  in standard notation

To express enormous figures which are in standard notation like 1,300,000 or exceedingly minuscule quantities like 0.0000000000045, scientists use scientific notation. Scientific notation, also referred to as exponential form, is one of the earliest mathematical techniques. It is well regarded by practitioners. People use scientific notation to handle situations where numbers are too large or too small to be calculated easily. Scientists, engineers, and mathematicians all use this technique. where as standard notation is way writing numbers in normal decimal form. The scientific method id most convenient denoting numbers as the numbers will be either too big or too small.

Ozone located in the troposphere is _______. A. Considered a pollutant b. Beneficial to living organisms c. Higher in concentrat
Aleonysh [2.5K]

The presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.

The atmosphere has been divided into five layers based on the availability and the composition of different elements.

<h3>Troposphere</h3>

The troposphere has been the lowest layer of the atmosphere. It has been closed to the earth surface and provides with clouds and maintain weather.

The gases on the troposphere are used by the organisms for living purpose. The ozone has been a harmful gas for living organisms.

Thus, the presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.
