What is the Lewis dot structure for SiS2

Answers

Answer 1

Answer:

What Is The Molecular Shape Of A Silicon Disulfide Molecule, SiS2 Trigonal Planar None Of Above Tetrahedral Linear Bent Trigonal Pyramidal 13.

Explanation:

Answer 2

The Lewis structure of SiS₂ shows the 4 valence electrons of Si, which are shared with each sulphur atoms and sulphur in turn shares two valence electrons with Si atom.

What is Lewis dot structure ?

The Lewis dot structure of a compound shows all the valence electrons as dots around its atom. From the dot structure  we can identify, which electron pairs are bonded , which are non-bonded and which are unpaired electrons.

SiS₂ is a covalent compound formed through the electrons sharing between two  sulphur and one silicon atoms. The silicon atom contains 4 valence electrons and one sulphur atom contains 6 valence electrons.

Si needs to gain 4 electrons and one S atom needs to gain 2 more electrons into their valence shell to achieve octet. Hence, One Si shares two electron to each S and S in turn shares its two electron with Si as shown in the image below.

In the combustion of hydrogen gas, hydrogen reacts with oxygen from the air to form water vapor. hydrogen+oxygen⟶water If you burn 58.9 g of hydrogen and produce 526 g of water, how much oxygen reacted?

Answers

Answer:

[tex]m_{O_2}=467gO_2[/tex]

Explanation:

Hello.

In this case, for the reaction:

[tex]2H_2+O_2\rightarrow 2H_2O[/tex]

The correct way to compute the oxygen that reacted is by considering the mass of hydrogen, 58.9 g, its molar mass, 2.02 g/mol, the 2:1 mole ratio between hydrogen and oxygen and the atomic mass of that gaseous oxygen 32.00 g/mol; therefore we use the following stoichiometric procedure:

[tex]m_{O_2}=58.9gH_2*\frac{1molH_2}{2.02gH_2}*\frac{1molO_2}{2molH_2} *\frac{32.00gO_2}{1molO_2} \\\\m_{O_2}=467gO_2[/tex]

The same result could have been obtained by using the mass of water since the law of conservation of mass is obeyed here.

If 5.00g of iron metal is reacted with 0.950g of Cl2 gas, how many grams of ferric chloride (FeCl3) will form?

Answers

Answer:

1.45g of FeCl3

Explanation:

The equation of the reaction is given as;

2Fe + 3Cl2 --> 2FeCl3

2 mol of Fe reracts with 3 mol of Cl2 to form 2 mol of FeCl3

Upon converting to mass using;

Mass = Number of moles * Molar mass

( 2 * 55.85 = 111.7g ) of Fe reacts with ( 3 * 71 = 213g ) of Cl2 to form ( 2 * 162.2 = 324.4g) of FeCl3

Cl2 is the limiting reactant as it determines how much of FeCl3 is formed

213g of Cl2 = 324.4g of FeCl3

0.950g of Cl2 = x

x = (0.950 * 324.4 ) / 213

x = 1.45g of FeCl3

If 200.00 mL of a solution of sugar and water contains 0.0025 moles of sugar, what is the concentration of the solution in units of moles per unit volume? Round decimals to the nearest thousandth where applicable. Do not include trailing zeros in decimal answers (e.g., 0.05 instead of 0.050).

Answers

Answer:

0.013 mol/L

Explanation:

Molarity, which is molar concentration or moles per unit volume, can be calculated using the formula:

M = n/V

Where; M = Molar concentration of solution

n = number of moles of solute

V = Volume of solvent

n = 0.0025 moles of sugar

V = 200.00mL of solution

Since 0.001L = 1mL

200mL = 0.200L

Therefore, M = n/V

M = 0.0025/0.200

M = 0.0125 mol/L

Round up to the nearest thousandth ~ 0.013mol/L

Consider the reaction of zinc metal with hydrochloric acid:
Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g).

If 29.39 × 1024 atoms of zinc completely reacted with hydrochloric acid, how many moles of hydrochloric acid must have reacted?

Do NOT include units in your entry. Report your answer with 3 SFs.

______________________ moles of HCl

Answers

Answer:

6.054×10²⁵

Explanation:

1)find number of moles of zinc

2)multiply the mole of zinc with 2

3)use the formula mol = number of particle/ avogadro constant

Total, 97.64 moles of hydrochloric acid (HCl) must have reacted.

To determine the number of moles of hydrochloric acid (HCl) that reacted, we first need to find the molar ratio between zinc (Zn) and hydrochloric acid (HCl) from the balanced chemical equation:

Zn(s) + 2 HCl(aq) → ZnCl₂(aq) + H₂(g)

From the equation, we see that 1 mole of Zn will reacts with 2 moles of HCl.

Given that 29.39 × 10²⁴ atoms of zinc reacted, we need to convert this quantity to moles. We can do this by using Avogadro's number:

1 mole of any substance = 6.022 × 10²³ atoms

Number of moles of zinc reacted = (29.39 × 10²⁴ atoms) / (6.022 × 10²³ atoms/mol)

Number of moles of zinc reacted ≈ 48.82 moles (rounded to 3 significant figures)

Now, using the molar ratio from the balanced equation, we can determine the number of moles of hydrochloric acid (HCl) that reacted:

Number of moles of HCl reacted = 2 × Number of moles of zinc reacted

Number of moles of HCl reacted ≈ 2 × 48.82 moles

≈ 97.64 moles

Therefore, approximately 97.64 moles of hydrochloric acid (HCl) must have reacted.

A scientist discovers remnants of an organism on a slide under his microscope. He can only identify a few components: a large vacuole, ridged cell wall, and a chloroplast. Was the organism prokaryotic or eukaryotic? How do you know?

Answers

Answer:

Eukaryotic (a plant cell)

Explanation:

The presence of a chloroplast indicates that the cell has membrane-bound organelles. This is not a feature of prokaryotic cells - only eukaryotic cells. Therefore, the cell is eukaryotic. The presence of a large vacuole, chloroplast, and rigid cell wall suggests its a plant cell as plant cells are the only eukaryotes with these features.

A student was performing a separation of a mixture of organic compounds. The final step of the process involved a filtration of the analyte from an aqueous solution. After drying the filtered solid for a very short period time, they took the melting point of the compound. The measured melting point range of the compound was 106 – 113.8 0C, while the literature melting point of the compound was 122.3 0C. The above scenario is a very common one in organic labs.
1. Do you think their sample was pure?
2. If not, then what do you think could be the source of error.
3. How do you think this error can be minimized?

Answers

Answer:

1) No

2) The solvent contaminated the analyte

3) The solvent should be evaporated properly before washing and drying the analyte

Explanation:

During separation of organic compounds, solvents are used. These solvents are able to contaminate the analyte and lead to a large difference in melting point of solids obtained.

However, the error can be minimized by evaporating the solvent before washing, drying and melting point determination of the solid.

There are basically two types of isotopes which include:Stable Isotopes are isotopes that do not emit radiation. Some examples include oxygen, carbon, hydrogen, etcRadioactive/ Non Stable Isotopes are those isotopes which are radioactive or emit radiation. Some examples include uranium-238, bismuth, etc.

In chemistry, one often uses a unit of charge known as the Faraday, F, which has the magnitude of the charge of 1 mole of electrons. How many faradays of charge does that correspond to

Answers

Answer:

1 Faraday

Explanation:

This question seeks to test proper understanding of Faraday's second law of electrolysis which states when the same quantity electricity passes through a solution of different electrolytes, the mass of the substance deposited is directly proportional to there chemical equivalence.

This law hints at the charges of ions being the chemical equivalence and also been represented as the unit for the quantity of electricity in faraday, F. Hence, a metal with the charge of 1+ can be displaced by 1F (which is equal to 96, 500 coloumbs). This charge also represents one molecule of electron, thus 1 faraday corresponds to one mole of electrons.

NOTE: It should be noted that a metal with the charge of 2+ can be displaced by 2F and so on.
