Group 1 substances are called ionic compounds and Group 2 substances are called covalent molecules. Write a

Answers

Answer:

An ion found in some compounds used as antiperspirants contains 13 protons and 10 electrons. What is its symbol?

Solution

Because the number of protons remains unchanged when an atom forms an ion, the atomic number of the element must be 13. Knowing this lets us use the periodic table to identify the element as Al (aluminum). The Al atom has lost three electrons and thus has three more positive charges (13) than it has electrons (10). This is the aluminum cation, Al3+.

What is the oxidation state of S in S2O32−?
A. +3 B. +2 C. –2 D. +4

Answers

Answer:

it'd be +2

Explanation:

Since 3 atoms of oxygen are present, so its combined oxidation number will be3(−2)=−6. Now this ion contains a charge of−2, where the sum of the oxidation number of all atoms in an atom is equal to−2. So the oxidation number of S in S2O2−3 should be +2.

How many moles are in 9.83 x 1021 atoms of Na

Answers

Answer:

0.016 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

[tex]n = \frac{9.83 \times {10}^{21} }{6.02 \times {10}^{23} } \\ = 0.01632...[/tex]

We have the final answer as

0.016 moles

What is true of an earthquake that causes major damage to buildings in an area?

It has a high magnitude.
It has a high frequency.
It has a low frequency.
It has a low magnitude.

Answers

The correct option is :

=》It has a high magnitude.

the damage caused by an earthquake is proportional to its magnitude, as much the magnitude is, that much damage will be caused by it.

The term used to indicate and earthquake that causes major damage to buildings in an area is called a high magnitude earthquake. Hence, option a is correct.

What is high magnitude earthquake?

The most typical way to gauge an earthquake's size is by its magnitude. No matter where you are or how violent the shaking is, it is the same number since it represents the size of the earthquake's source.

The USGS no longer uses the outmoded Richter scale to determine the magnitude of major, teleseismic earthquakes. Several magnitude scales measure various aspects of the earthquake, but the Richter scale measures the biggest wobble (amplitude) on the recording.

Currently, the USGS uses the Moment Magnitude scale to report earthquake magnitudes, however many different magnitudes can be calculated for comparison and research. Therefore, option a is correct.

Thus, the pH level of the solution is 9.54

The half-life for a 400-gram sample of radioactive element X is 3 days. How much of element X remains after 15 days have passed?

A.
12.5 g

B.
25 g

C.
50 g

D.
100 g

Answers

Answer:

The correct answer is - A. 12.5 gram.

Explanation:

Given:

The initial amount of sample = 400 gram

the half-life cycle = 3 days

after 15 days remain value = ?

Solution:

The number of half-lives in 15 days = 15/3

= 5 half-lives

the remaining amount of sample after one half-life 3 days = 400/2 = 200

the remaining amount of sample after 2nd half-life or 6 days= 200/2 = 100

the remaining amount of sample after 3rd half-life or 9 days= 100/2 = 50

the remaining amount of sample after 4th half-life or 12 days= 50/2 = 25

the remaining amount of sample after 5th half-life or 15 days= 25/2 = 12.5 gram

Thus, the correct answer is = 12.5 g.

Think about the decomposition reaction of ozone.

2 O3 ----> 3 O2

If 71.7 mol ozone are in this reaction, what is the theoretical yield of O2 (in gram)?

Answers

Answer:

3441.6 grams.

Explanation:

2 O₃ → 3 O₂

First we convert 71.7 moles of ozone (O₃) into moles of oxygen gas (O₂), using the stoichiometric coefficients of the reation:

71.7 mol O₃ * [tex]\frac{3molO_2}{2molO_3}[/tex] = 107.55 mol O₂

Then we convert 107.55 moles of O₂ into grams, using the molar mass of O₂:

107.55 mol * 32 g/mol = 3441.6 g

What is the empirical formula for a compound if a 2.50g sample contains 0.900g of calcium and 1.60g
of chlorine? (3pts]

Answers

Answer:

CaCl₂

Explanation:

First we convert the given masses of elements into moles, using their respective molar masses:

0.900 g Ca ÷ 40 g/mol = 0.0225 mol Ca1.60 g Cl ÷ 35.45 g/mol = 0.045 mol Cl

Now we divide those numbers of moles by the lowest value among them:

0.0225 mol Ca / 0.0225 mol = 10.045 mol Cl / 0.0225 mol = 2

Meaning the empirical formula for the compound is CaCl₂.

How many grams of N2 is needed to produce 2000 grams NH3?

Answers

Answer:

1644 g

Explanation:

Step 1: Write the balanced equation

N₂ + 3 H₂ ⇒ 2 NH₃

Step 2: Calculate the moles corresponding to 2000 g of NH₃

The molar mass of NH₃ is 17.03 g/mol.

2000 g × 1 mol/17.03 g = 117.4 mol

Step 3: Calculate the moles of N₂ needed to produce 117.4 moles of NH₃

The molar ratio of N₂ to NH₃ is 1:2. The moles of N₂ needed are 1/2 × 117.4 mol = 58.70 mol

Step 4: Calculate the mass corresponding to 58.70 moles of N₂

The molar mass of N₂ is 28.01 g/mol.

58.70 mol × 28.01 g/mol = 1644 g

How many kilojoules of energy are required to heat 50.0 g of ethyl alcohol from 60.0 °C to 78.4 °C and vaporize it? The specific heat of ethyl alcohol is 2.138 J/g°C; heat of vaporization is 853 J/g.

Answers

Answer:

44.62 kJ

Explanation:

Firstly, we calculate the energy needed to heat the liquid (ethyl alcohol) by using the formula:

Q = m × c × ∆T

Where;

Q = Amount of heat (J)

m = mass (g)

c = specific heat of ethyl alcohol = 2.138 J/g°C

∆T = change in temperature (°C)

According to the information given in this question;

Q = ?, m = 50.0g, ∆T = (78.4°C - 60°C) = 18.4°C

Therefore, using Q = mc∆T

Q = 50 × 2.138 × 18.4

Q (amount of energy needed to heat ethyl alcohol) = 1966.96 J

Next, we calculate and add the amount of heat needed to vaporize by using the formula;

How many kilojoules of energy are required to heat 50.0 g of ethyl alcohol from 60.0 °C to 78.4 °C and vaporize it? The specific heat of ethyl alcohol is heat of vaporization is 853 J/g.
