Calculate the percent yield if a student produces 3.3 grams of a substance from a reaction when they shouldve produced 5,5 grams based on their calculations

Answer:

134.5 g

Explanation:

Let us recall that 1g of water = 1cm3 of water

Hence;

1,640 g of water =  1,640 cm3 of water or 1.64 L

This is now the volume of the solution

Now;

m/M = CV

m = mass of the solute

M = molar mass of the solute

C = concentration of the solution

V = volume of the solution

m/84.9947 g/mol = 0.965 M *  1.64 L

m = 0.965 M *  1.64 L * 84.9947 g/mol

m = 134.5 g

An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H+ cation and the anion of the acid.

Answer:

B: The transport oxygen and nutrients around your body and help to get rid of wastes

Explanation:

The circulatory system carries oxygen and nutrients to the body, but it can also help get rid of waste (though that isn't a huge function of it).

Explanation:

11. The correct option is B. The range for polar covalent bond is; 0.3 - 1.4

12. C. This is because there is uneven distribution of the charge. Unlike in the other options which are molecules of the same atoms with equal electronegativity.

13. A. Resonance structures is the correct option. It describes electrons in certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula.

14. A. Lower electronegativity values means the electrons are more likely to be shared than transferred (gain/lost).

15. D. H2O is more polar than H2S because of the electronegativity of oxygen. H2O also has hydrogen bonds.

16. C. Due to the geometry of the other molecules, the polarity are cancelled.So they have a net polarity of zero.

Answer:

The Major features of the ocean floor are:

Explanation:

1. Continental Shelf: This refers to the part of the land on every continent that is covered with water that is not too deep. The types of animals that can be found on the continental shelf are:

Crab, Tuna, Lobster, Dungeness cod, etc. Within the Continental shelf, there are permanent rocks that house other organisms such as sponges, anemones, clams, sponges, oysters. The continental shelf also contains the route of migration for bigger animals such as sea turtles dolphins and even whales.

2. Continental Slope: This spans from the shelf break to the continental rise.  It can slope up to 4 degrees. Slopes can be created by faulting, slumping of huge boulders of sediments, rifting, etc.

Some of the aquatic animals that can be found in this region include but are not limited to:

Sablefish, Dover sole rockfish, etc.

3. Continental rise

This part of the ocean floor usually has a very steep gradient or angle slope. It slopes very steeply into the abyssal plain of the ocean.

The following can help form continental rise:

4. Abyssal Plain.

This is the real bottom of the ocean. There is a very high probability that one would find animals such as nematodes, polychaetes, etc which are all types of worms down there. The Abyssal plain is also home to molluscs,  and echinoderms.

5. Oceanic Trench

Sometimes there is a long and narrow indenture or depression along the seafloor. These are called Trenches. Trenches are sometimes formed by the boundaries between one lithospheric plate and another. The deepest trench on earth is found in the Pacific Ocean. It has been nick-named the Challenger Deep and said to be the deepest point known on earth reaching almost 11 kilometers.

6. Mid-Ocean Ridge

This is a mountain range underneath the ocean. It is formed when there is an upward push by convection currents of the mantle beneath the oceanic crust. When this happens and molten magma is ejected or created at the boundary between the plates, the result is a Mid-Oceanic Ridge.

Answer:

Be^2+

Explanation:

The atomic number indicates the number of protons so the element is Be (beryllium)

So now we know that a neutral atom contains four electrons but there are 2 so that means two electrons were taken away, making it positive. It would be a 2+ charge.

Answer:

If 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.

Explanation:

The balanced reaction is:

CuO + CO₂ → CuCO₃

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

You can see that the stoichiometric relationship between CuO and CO₂ is 1: 1. In other words, for each mole of CuO that reacts, one mole of CO₂ will also react.

So if 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.

Answer:

~0.14

Explanation:

There are roughly ~0.14 moles in 4.5g of Sulfur. 1 mol = 32.06 g of Sulfur, so we just find the ratio and then multiply.

Answer:

[tex]\boxed {\boxed {\sf About \ 0.14 \ mol \ S }}[/tex]

Explanation:

To convert from grams to moles we must use the molar mass. This can be found on the Periodic Table.

We can use this number as a ratio or fraction.

[tex]\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Multiply by the given number of grams: 4.5

[tex]4.5 \ g \ S *\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Flip the fraction so the grams of sulfur cancel.

[tex]4.5 \ g \ S *\frac{1 \ mol \ S }{32.07 \ g \ S}[/tex]

[tex]4.5 *\frac{1 \ mol \ S }{32.07 }[/tex]

[tex]\frac{4.5 \ mol \ S }{32.07 }[/tex]

[tex]0.140318054 \ mol \ S[/tex]

The original measurement of grams had 2 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place.

The 0 in the thousandth place tells us to leave the 4.

[tex]0.14 \ mol \ S[/tex]

There is about 0.14 moles of sulfur in 4.5 grams.

Answer:

(C5H7)8

Explanation:

It's empirical formula is given as; C5H7

Molar mass of carbon(C) = 12 g/mol

Molar mass of hydrogen(H) = 1 g/mol

We are told that it's molar mass is 536 g/mol.

To find the molecular formula;

Molecular formula = n × empirical formula

Thus;

n = 536/((12 × 5) + (1 × 7))

n = 8

Thus;

Molecular formula = (C5H7)8

Answer:

A. two atoms of the element from the first column and one atom of the element from the sixteenth column.

Explanation:

If an ionic compound formed between an element from the first column of the periodic table and another from the sixteenth column, you would expect the compound to include two atoms of the element from the first column and one atom of the element from the sixteenth column.

The periodic table is arranged in rows and columns. The rows are periods while the columns are groups.

The first column of the periodic table contains elements that form univalent ions hence they have a valency of 1. The elements in the sixteenth column usually form divalent negative ions and have a valency of 2.

An example of an element of the first column is sodium while an example of an element of the sixteenth column is sulphur.

During ionic bond formation, there is an exchange of valency such that the formula of a compound formed between sodium and sulphur is Na2S.

Therefore, when an ionic compound formed between an element from the first column of the periodic table and another from the sixteenth column, you would expect the compound to include two atoms of the element from the first column and one atom of the element from the sixteenth column.
