If 13 grams of copper sulfate is reacted with zinc how much of each product is produced?

Answers

Answer 1

Answer:

No. Of Moles of zinc = m/Ar

= 13/ 65.38 = 0.198 moles

From balanced equation, Mole ration between CuSO4 and Zn is 1 : 1

So only 0.198 moles of CuSO4 reacts, it is in excess

Mass = no of Moles X Mr

Mass = 0.198 X 159.5 = 31.59 grams

Volume = mass m denisty

Volume j 31.59 / 3.6 = 8.78 ml

What do modern scientist use in classifying organisms that Linnaeus did not use?

Answers

Answer:

The taxonomic units in modern taxonomy are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class, order, family, genus, and species.

The evidence used by scientists use to classify organisms are essentially form and evolutionary relationships.

Evolutionary relationships.

The diversity of living organisms on earth is very overwhelming. Human beings have come up with ways of organizing, or classifying, biological diversity throughout human history.

Organisms can be classified according to any number of criteria, including overall similarities, colors or ecological factors. It was agreed that the most useful way for scientists to organize biological diversity is to group organisms according to shared evolutionary history or characteristics. Grouping did not only result in an organized classification but it also contains and conveys information about our understanding of the evolutionary history of those groups.

Although our understanding of evolutionary relationships among organisms has greatly improved but it is not complete. Relationships among organisms and groups of organisms continues to be revised as new data becomes available comparing them to the past. Almost all taxonomies or systems of nomenclature based on evolutionary relationships among organisms are being revised.

The use of binomial nomenclature system was proposed by Carl Linnaeus. In this system, the phylogenetic relationship, cladistic analysis, and systematic approaches are used.

The H3O+ ion concentration of a solution is 1 × 10–5 mole per liter. This solution is
A. acidic and has a pH of 5
B. acidic and has a pH of 9
C. basic and has a pH of 5
D. basic and has a pH of 9

Answers

The given [tex]H_3O^+[/tex] ion concentration of a solution is an acidic solution and has a pH of 5.

How does the pH scale measure?The letters pH stand for the potential of hydrogen since pH is effectively a measure of the concentration of hydrogen ions (that is, protons) in a substance.The pH scale measures the relative acidity and alkalinity of solutions.It's a negative logarithmic scale of base ten that measures the potential of a solution to accept protons in the form of hydrogen ions.A pH scale ranges from 0 to 14 with 7 being neutral. A pH lower than 7 is considered acidic and a pH greater than 7 is considered basic (alkaline).

What is the pH value of an [tex]H_3O^+[/tex] ion?

pH can be calculated by using the following equation:

pH = -1(log[H3O+])

Where [H3O+] is the concentration of hydronium ions (hydrogen ions).

The concentration is given as 1 × [tex]10^-^5[/tex] mole per liter.

So, if [H3O+] = 1x[tex]10^-^5[/tex] mol/L,

then the pH = -1(log(1 × [tex]10^-^5[/tex] )) = 5

So, the pH of the given solution is 5. The value is less than 7. Hence it is considered an acidic solution.

Therefore, The given solution is an acidic solution with a pH of 5.

Which element, when combined with Fluorine, would form an COVALENT compound?

A.Lithium
B.Iron
C.Phosphorus
D.Sodium

Answers

Answer:

Explanation:

A covalent compound is a compound formed by covalent bonds. A covalent bond is formed between two atoms where electrons are shared between the two atoms. This forms a molecule.

What determines whether two elements will form a covalent compound or not is the number of valence electrons present in each of the elements.

Fluorine will form a covalent compound with phosphorous because fluorine has 5 electrons in its outermost shell. It needs 3 more to become stable.

Phosphorous also has 5 valence electrons. It needs 3 more to become stable.

What happens is that 3 atoms of FLuorine combine with one atom of Phosphorus, sharing the valence electrons between themselves. This leads to the formation of the PF3 molecule.

Both the Phosphorous and the Fluorine are now stable.

Answer: Phosphorus

Explanation: since both are non-metals they would both create a covalent bond.

A 25.0mL solution of KOH is neutralized with 30.3 mL of 0.100M HBr. What is the concentration of the original KOH solution?

Answers

Answer:

The concentration of the original KOH solution is 0.1212 M.

Explanation:

Dilution is the process to reduce the concentration of solute in solution. This is accomplished by adding more solvent to the same amount of solute. In other words, dilution is the procedure followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding solvent to an existing solution.

As only solvent is being added, the consequence is that by not increasing the amount of solute, but if the amount of solvent, the concentration of the solute decreases.

The expression for the dilution calculation is:

Ci* Vi = Cf* Vf

where:

Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volume

In this case:

Ci= ? Vi: 25 mL Cf: 0.1 M Vf: 30.3 mL

Replacing:

Ci* 25 mL= 0.1 M* 30.3 mL

Solving:

[tex]Ci=\frac{0.1 M*30.3 mL}{25 mL}[/tex]

Ci=0.1212 M

The concentration of the original KOH solution is 0.1212 M.

Answers

Answer: The new temperature of container is 123 K.

Explanation:

Given: [tex]P_{1}[/tex] = 795 mm Hg,     [tex]T_{1}[/tex] = 273 K

[tex]P_{2}[/tex] = 358 mm Hg,          [tex]T_{2}[/tex] = ?

Formula used to calculate the new temperature is as follows.

[tex]\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\\frac{795 mm Hg}{273 K} = \frac{358 mm Hg}{T_{2}}\\T_{2} = 123 K[/tex]

Thus, we can conclude that the new temperature of container is 123 K.

What are the two limitations of earth plates

Answers

Answer:

The tectonic style and viability of modern plate tectonics in the early Earth is still debated. Field observations and theoretical arguments both in favor and against the uniformitarian view of plate tectonics back until the Archean continue to accumulate. Here, we present the first numerical modeling results that address for a hotter Earth the viability of subduction, one of the main requirements for plate tectonics. A hotter mantle has mainly two effects: 1) viscosity is lower, and 2) more melt is produced, which in a plate tectonic setting will lead to a thicker oceanic crust and harzburgite layer. Although compositional buoyancy resulting from these thick crust and harzburgite might be a serious limitation for subduction initiation, our modeling results show that eclogitization significantly relaxes this limitation for a developed, ongoing subduction process. Furthermore, the lower viscosity leads to more frequent slab breakoff, and sometimes to crustal separation from the mantle lithosphere. Unlike earlier propositions, not compositional buoyancy considerations, but this lithospheric weakness could be the principle limitation to the viability of plate tectonics in a hotter Earth. These results suggest a new explanation for the absence of ultrahigh-pressure metamorphism (UHPM) and blueschists in most of the Precambrian: early slabs were not too buoyant, but too weak to provide a mechanism for UHPM and exhumation.

Ammonia gas (NH3) combines with oxygen gas (O2) to form diatomic nitrogen gas and water vapor. If 4.0 grams of ammonia react, how many liters of nitrogen gas are produced? The gas is collected at 32.00°C and a pressure of 2.6 atmospheres.

Answers

Answer:

1.13 L

Explanation:

First, we have to write the chemical equation for the reaction between ammonia gas (NH₃) and oxygen gas (O₂) to give nitrogen gas (N₂) and water (H₂O), as follows:

NH₃(g) + O₂(g) → N₂(g) + H₂O(g)

Then, we have to balance the equation (we write first the coefficient 2 for NH₃ to balance N atoms, then a coefficient of 3 for H₂O to balance H atoms, and finally 1/3 to balance the O atoms):

2 NH₃(g) + 3/2 O₂(g) → N₂(g) + 3 H₂O(g)

In the balanced equation, we can see that 1 mol of N₂ is produced from 2 moles of NH₃. We convert the moles of NH₃ to grams by using its molecular weight (MW):

MW(NH₃) = 14 g/mol N x 1 + (1 g/mol H x 3) = 17 g/mol

grams of NH₃ = 17 g/mol x 2 = 34 g

Thus, we have the stoichiometric ratio:

1 mol of N₂/2 mol NH₃ = 1 mol of N₂/34 g NH₃

To calculate how many moles of N₂ are produced from 4.0 of NH₃, we multiply the mass by the conversion factor:

4.0 g NH₃ x 1 mol of N₂/34 g NH₃ = 0.1176 moles N₂

Finally, we calculate the liters of N₂ gas by using the ideal gas equation:

PV = nRT ⇒ V = nRT/P

We introduce the data in the equation:

T = 32.00°C + 273 = 305 K

P = 2.6 atm

R = 0.082 L.atm/K.mol (is the gas constant)

n= 0.1176 moles

⇒ V = nRT/P = (0.1176 mol x 0.082 L.atm/K.mol x 305 K)/(2.6 atm)

                     = 1.13 L

When carbon disulfide, CS2, forms from its elements. Heat is absorbed. How much heat would be required to produce 5.0 moles of carbon disulfide

Answers

Answer:

5.9 × 10² kJ

Explanation:

When carbon disulfide, CS₂, forms from its elements, heat is absorbed. The corresponding value for the standard enthalpy of formation of carbon disulfide is 117.36 kJ/mol. The thermochemical equation that represents this process is:

C(graphite) + 2 S(s, rhombic) ⇒ CS₂(g)   ΔH°f = 117.36 kJ/mol

117.36 kJ of heat are absorbed when 1 mole of CS₂ is formed. The amount of heat absorbed when 5.0 moles of CS₂ are formed is:

5.0 mol × 117.36 kJ/mol = 5.9 × 10² kJ
