Classify the following monosaccharides according to the position of the carbonyl group and the number of carbon atoms in the molecule.

Answer:

When air is admitted into the well, the water recedes from the level of static head to the bottom of the discharge pipe. The displaced column of liquid rises up the discharge pipe. Air bubbles mix with water and this reduces the specific gravity of the column of water sufficiently to lift it to the surface.

Answer:

All of them derive from a common ancestor. They each share something in their DNA that ties into their past selves, which were more closely related. As they evolved, they became more and more distant, but we can still trace them back to the olden days.

Also they all have scales.

The formation of a gas is a clue to chemical changes. The bubbles of gas that you observed form when an antacid is dropped into water is an example of change. ... As wood burns, it turns into a pile of ashes and gases that rise into air.

Explanation:

Explanation:

Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an element. ... A substance that can be broken down into chemically simpler components (because it has more than oneelement) is a compound.

Since the molecular weight of water is about 18 g/mol, you have about 1 mol of water. So, now we know that it takes approximately 46.2 kJ of heat energy to warm 18.02g of water from 25C to 100C and then to vaporize it into steam. Hopefully this helped!

Answer:

7.22 L

Explanation:

From the question,

Applying Charles law,

V₁/T₁ = V₂/T₂...................... Equation 1

Where V₁ = Initial volume of gas, V₂ = Final volume of gas, T₁ = Initial Temperature of gas in Kelvin, T₂ = Final Temperature of gas in Kelvin

Make V₂ the subject of the equation

V₂ = (V₁×T₂)/T₁................. Equation 2

Given: V₁ = 5.00 L, T₁ = 20 °C = (20+273) K = 293 K, T₂ = 150 °C = (150+273) K = 423 K

Substitute these value into equation 2

V₂ = (5.00×423)/293

V₂ = 7.22 L

Sedimentary basins are regions of the Earth where long-term subsidence creates accommodation space for accumulation of sediments. As the sediments are buried, they are subject to increasing pressure and begin the processes of compaction and lithification that transform them into sedimentary rock.

Copper(II) sulphate – sodium hydroxide reaction

The reaction between copper(Il) sulphate and sodium hydroxide solutions is a good place to start. If you slowly add one to the other while stirring, you will get a precipitate of copper(II) hydroxide, Cu(OH)2.

Answer:

Due to warm temperature.

Explanation:

There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.

Answer:

83.674 grams of Fe

Explanation:

9.02 x 10²⁸ atoms

To convert from atoms to grams, we first need to convert atoms to moles. To do this, divide the atoms by Avogadro's Number, 6.02 x 10²³

9.02 x 10²⁸ ÷ 6.02 x 10²³

= 1.498 moles of Fe

Now we need to convert moles to grams. To do this, multiply the moles by the molar mass of Fe. The molar mass can be found on the periodic table.

1.498 • 55.845

= 83.674 grams of Fe

Hope this helps!

The answer is Option B, NaOH is the solution student should use as the base solution in this acid-base titration experiment to determine the amount of ascorbic acid in different brands of juice.

What is an Acid Base Titration ?

An acid–base titration is a method of quantitative analysis.

It is used for determining the concentration of an acid or base by neutralizing it with a standard solution of base or acid of known concentration.

An indicator is used to monitor the progress of the acid–base reaction.

Ascorbic acid, HC₆H₇O₆ is an acid. So can be titrated with a base , sodium hydroxide, NaOH using the indicator, phenolphthalein.

HC₆H₇O₆(aq) + NaOH(aq) → NaHC₆H₇O₆(aq) + H₂O(l)

Among the options , HCl is an acid , LiBr , CaCl₂ are salts , NaOH is the only base.

Phenolphthalein changes from colorless to pink (or red) when all of the acid gets neutralized.

Therefore NaOH is the solution student should use as the base solution in this acid-base titration experiment to determine the amount of ascorbic acid in different brands of juice.

Answer:

10 moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​.

Explanation:

The balanced reaction is:

N₂ + 3 H₂ → 2 NH₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Then you can apply the following rule of three: if by reaction stoichiometry 1 mole of nitrogen produces 2 moles of ammonia, 5 moles of nitrogen produces how many moles of ammonia?

[tex]moles of ammonia=\frac{5 moles of nitrogen*2 moles of ammonia}{1 mole of nitrogen}[/tex]

moles of ammonia= 10

10 moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​.
