Determine The Formal Charge On Each Atom In The Structure.

Answers

Answer 1
The answer is -3, because the element phosphorus has a charge of 3-.
Answer 2

The formal charge of an ion in a compound can be find out from  the number of bonds, valence electrons and nonbonding electrons. The charge of single bonded oxygens is  -1 and that of double bonded oxygen is 0. The formal charge of P is zero.

What is formal charge?

Formal charge of an ion is the charge it carries in one formula unit of a compound. It can be find out using the formula as follows:

Formal charge = number of valence electrons - number of non bonding electrons - bonding electrons/2.

Here, oxygen has 6 valence electrons and 2 and 6 nonbonded electron in a single bond. Number of bonded electron is 2 .

formal charge =  6 - 6-2/2 = -1.

The formal charge of double bonded oxygen = 6 - 4 - 4/2 = 0

The valence electrons in phosphorus is 5 and there is non non bonded electrons in it and the number of bonded electrons is 10.

Formal charge = 5 - 0 - 10/2 = 0.

Find the initial temperature of 45.0g of water if its final Temperature after submerging a metal with the mass of 8.5g is 22.0°C . The initial temperature of metal before submerging it to water is 82.0°C

Answers

The initial temperature of the water that resulted in the final temperature of the water-metal mixture is 20.7 ⁰C.

"Your question is not complete, it seems to be missing the following information;"

the specific heat capacity of the metal is 0.45 J/g⁰C.

The given parameters;

mass of water, [tex]m_w[/tex] = 45 gfinal temperature of the water, [tex]t_w[/tex] = 22 ⁰Cmass of the metal, m = 8.5 ginitial temperature of the metal, t = 82 ⁰C.specific heat capacity of the metal, c = 0.45 J/g⁰C.

The initial temperature of the water will be calculated by applying the principle of conservation of energy;

heat gained by water = heat lost by metal

[tex]Q_{water} = Q_{metal}[/tex]

[tex]m_wc_w \Delta t_w = mc\Delta t[/tex]

where;

[tex]c_w[/tex] is the specific heat capacity of the water = 4.184 J/g⁰C.

Substitute the given values;

45 x 4.184 x (22 - t) = 8.5 x 0.45 x (85 - 22)

4142.16  - 188.28t = 240.98

188.28t  = 4142.16  - 240.98

188.28t  = 3901.18

[tex]t = \frac{3901.18}{188.28} \\\\t = 20.7 \ ^0 C[/tex]

Thus, the initial temperature of the water that resulted in the final temperature of the water-metal mixture is 20.7 ⁰C.

b) below 7 because HCl(aq) is a strong acid
c) below 7 because it is determined by HF(aq)
d) at 7 because it is determined by H2O(l)

Answers

At the equivalence point, the NaF completely reacts with the HCl

The correct option that gives the equivalence point when titrating NaF solution with HCl(aq), occur at a pH value is option c);

c) Below 7 because it is determined by HF (aq)

Reason:

The ionic equation of the reaction taking place in the titration is presented as follows;

NaF + HCl → HF + NaClNa⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → HF (aq)+ Na⁺(aq) + Cl⁻(aq)

Therefore, by removing the spectator ions, we get;

F⁻(aq) + H⁺(aq) → HF(aq)

Therefore;

The net ionic equation is the formation of hydrofluoric acid, HF, which is a

weak acid, therefore, the pH value will be below 7 because it is determined

by HF

During oxidation of ethanol to ethanol, the ethanol formed was found to be contaminated with unconverted ethanol, describe how you would obtain ethanal free from ethanol​

Answers

Answer:

Ethanol is oxidised by acidified sodium dichromate in a test tube reaction, firstly to form ethanal (acetaldehyde), and with further oxidation, ethanoic acid (acetic acid)

Procedure

Place about 3 cm3 of acidified sodium dichromate solution in a boiling tube.

Use a teat pipette to add 5–7 drops of ethanol, with shaking.

Cool the mixture in the tube under a tap. Note the sweetish smell of ethanal (acetaldehyde) at first, then becoming sharper as oxidation continues and forms ethanoic acid (acetic acid).

When the reaction has subsided, the mixture can be warmed gently; the smell of ethanoic acid will become more noticeable.

The process of how we would obtain ethanal free from ethanol is described in the explanations below.

In Chemistry, Ethanol undergoes oxidation in the presence of sodium dichromate plus sulphuric acid to yield ethanal and water.

The procedure for achieving this in the laboratory is as follows;

Step 1; Measure a quantity of a solution of sodium dichromate acidified in a dilute sulphuric acid and pour into a test tube.

Step 2; Add excess ethanol. This is because if we don't do so there will be plenty of oxidizing agent to carry out a second operation which changes the aldehyde to ethanoic acid. However, we need only the aldehyde.

Step 3; When the aldehyde ethanal begins to form which will be evident by the change in the colour of solution from orange to green, then the mixture should be distilled from the test tube and tbethe aldehyde collevted so that it doesn't undergo additional oxidation into ethanoic acid.

In 1–2 sentences, explain why weather can be predicted only as probable, not definite.

Answers

Answer:

Meteorologists use computer models to predict the weather. And computational power has come an extended way. Yet meteorologists still have trouble correctly predicting the weather over some days. Sometimes they don’t even comprehend right over 24 hours! Why does this happen? Their ability to predict the weather is restricted by the number of available data, the time available to research it, and therefore the complexity of weather events.

Explanation:

Expressing personal ability to predict weather is limited by the amount of data available, the amount of time available to research it, and thus the complexity of weather events.

What is weather forecasting?

Weather forecasting is the prediction of the weather using physics principles supplemented by a variety of statistical and empirical techniques.

The goal of weather prediction is to provide information that people and organizations can use to reduce weather-related losses.

It also improve societal benefits such as life and property protection, public health and safety, and economic prosperity and quality of life.

As much information as possible about the current weather and the state of the atmosphere is gathered.

Temperature, pressure, humidity, and wind speed observations are collected from around the world and fed into powerful supercomputers.

Three factors limit the ability to predict the weather:

The amount of available data.The time available to analyze it.The complexity of weather events.

Thus, weather can be predicted only as probable, not definite.
