3 0

Beanium or signically Bn

\\ \sf\ast\Rrightarrow Atomic\:Mass=137.327u

  • Lets simplify with significant figures

\\ \sf\ast\Rrightarrow 137.33u

\\ \sf\ast\Rrightarrow 137.3u

\\ \sf\ast\Rrightarrow 137u

Calculate the osmotic pressure of a 5.5M glucose solution at 20 degrees Celsius
NeTakaya

The osmotic pressure is a colligative property which depends upon the number of molecules and not the type of molecules

The relation between osmotic pressure and concentration is

πV = nRT

where

π = Osmotic pressure [ unit atm] = ?

V = volume

n = moles

R = gas constant = 0.0821 L atm / mol K

T = temperature = 20°C = 20 + 273.15 K = 293.15 K

also

Molarity = moles / Volume

So

Molarity = n/V = 5.5 M

Putting values

π = MRT

π = 5.5 X 0.0821 X 293.15 = 132.37 atm

Osmotic pressure of given glucose solution will be 132.37 atm

Descibe the methods you will use to identify and isolate yeast and bacteria in a pineapple juice​
zalisa [80]

Answer:

The correct answer would be the use of differential and selective growth medium.

Explanation:

The mixed colonies states of certain species can be developed on the differential and specific media relying on the morphology saw in the general media. These types of selective and differential media will allow certain microorganisms to grow only and not all the rest species present on the media.

It will help in recognizing species present in the mixed colonies present in such a growth medium. Different tests like catalase can be performed to dispose of certain choices not long before the utilization of the differential and particular media.

Thus, the correct answer would be the use of differential and selective growth medium.

Compounds Lab Report
lukranit [14]

Name and Title:

Colleen DeBruin, Hillary Mulkavits, 11/18/2020, compounds lab.

Objectives(s):

to build chemical compounds from known elements

Hypothesis:

if I use oxygen hydrogen and carbon then I can make five new compounds in four minutes

Procedure:

The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using your summary questions at the end of your virtual lab activity, please clearly define the dependent and independent variables of the experiment.

Data:

Record the composition of each of your compounds below. Be sure to include the number of atoms for each element. An example has been supplied for you.

Compound Name Chemical Formula Sodium (Na) Atoms Calcium (Ca) Atoms Hydrogen (H) Atoms Oxygen (O) Atoms Carbon (C) Atoms Chlorine (Cl) Atoms

Ex: Sodium

hypochlorite NaClO 1 0 0 1 0 1

Water H20 o 0 1 2 0 0

Glucose C6H12O6 0 0 12 6 6 0

Formic/methanoic acid HCOOH 0 0 2 2 1 0

Butanoic Acid C3H7COOH 0 0 8 2 4 0

Carbon Dioxide C02 0 0 0 2 1 0

Carbon Monoxide CO 0 0 0 1 1 0

Fructose C6H12O6 0 0 12 6 6 0

0 0 0

0 0 0

0 0 0

Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.

I found as many combinations of carbon hydrogen and oxygen as possible

If there is a job that combines elements you would be doing that every day making it an every day matter

elements are like people, they are all different causing them to react differently and be more reactive

H20 has four because there are 2 oxygen and one hydrogen because of the numbers in the name of the compound

Yes because two elements can form two different types of bonds causing different outcomes

If this isn't right I'm sorry but I had it as an assignment so we will get it wrong together lol
