C. Uprooted plants dry and die. Why?​

Answers

Answer 1

Because:

Their roots are no longer in the soil. Thus, can't absorb water and mineral ions needed for plant growth via photosynthesis.

Hope this helps!

Answer 2

Answer:

Yes

Explanation:

Well this is because when a plant is planted water goes from the soil, into the roots then finally distributed to other parts of the plant.

So when plants have been plucked or uprooted water no longer has access to the plant which may result to the plant being dried up and will possibly die

Name the following carboxylic acid
COOH
A. 3-ethyl-2-methylheptanoic acid
B. 2-ethyl-1-methylhexanoic acid
C. 2-methyl-3-ethylheptanoic Acid

Answers

The name of the carboxylic acid would be 2-methyl-3-ethylheptanoic acid.

Naming or carboxylic acids

Carboxylic acids are named based on the longest carbon chain and the counting starts from the carboxylic acid's functional group.

Thus, in this case, the compound would be a heptanoic acid because the longest chain towards the functional group has 7 carbons.

This means 2 branches exist in the compound. The first one has a single carbon while the second one has 2 carbon atoms. This means they are methyl and ethyl groups respectively.

The branches are located on the second and third carbon on the main chain. Thus the compound's name is 2-methyl-3-ethylheptanoic Acid.

what volume of a 0.25M solution can be prepared with 28.5g of k2s? (molar mass=110.26g)

Answers

Answer:

volume = 1.04 dm^3

Explanation:

Data:

volume = ?

Molarity, M = 0.25M

mass = 28.5g

Molar mass = 110.25g

Moles = ?

Solution:

First find number of moles,

 moles = mass in gram / molar mass

             = 28.5 / 110.25

              = 0.258

              ≈ 0.26 moles

Now,

          Molarity = [tex]\frac{no. of moles}{volume in dm^3}[/tex]

So,

           Volume in dm^3 = [tex]\frac{no. of moles}{molarity}[/tex]

                                       =  0.26 / 0.25

                         Volume  = 1.04 dm^3

A liquid, solid, or gas's volume is the amount of three-dimensional space it occupies. Although there are many different units that may be used to indicate volume, the most common ones are liters, m³, gallons, milliliters, teaspoons, as well as ounces.

Gases have a volume equal to the internal capacity of the container since they fill their containers to the brim. Containers with a designated volume or one whose interior form is known are frequently used to measure liquids. Measuring cups, graded cylinders, flasks, as well as beakers are a few examples of the tools used to quantify liquid volume.  3.0x10⁻¹²kiloliters represents the greatest volume.

1. At constant temperature, the volume of a gas was found to be 500cm³ at a pressure of 760mmHg. If the pressure of the gas is doubled what will be the new volume of the gas?​

Answers

Answer:

SEE BELOW

Explanation:

Given   500 cm^3 = V1    760 mm = P1     (760*2) = P2

Required   V2

P1V1 = P2V2

RE-ARRANGE  TO    P1V1/P2 = V2

(760)(500) /(760*2) = V2

V2 = 250 ML

According to Boyles law

So if pressure is increased volume will be decreased and vice versa

Now pressure is doubled means multiplied by 2

What is a Balanced Chemical Equation ?

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

There are two types of numbers that appear in chemical equations.

There are subscripts, which are part of the chemical formulas of the reactants and products;

and there are coefficients that are placed in front of the formulas to indicate how many molecules of that substance is used or produced.

Balance The Equation:

Pb²⁺ + Au²⁺ = Pb⁴⁺ + Au

Answers

Based on the molar mass of the protein, the concentration of the unknown protein is 0.0011 mM (millimolar).

What is concentration?

Concentration is the amount of a solute present in a given volume of substance.

Concentration = moles/volume

Moles of protein = mass/molar mass

molar mass of protein = 118 × 64 = 7552 g/mol

Moles of protein in 8.3 g = 8.3/7552 = 0.0011 moles

Concentration = 0.0011 mole/mL = 0.0011 mM.
