The density of aluminum is 2.70 g/cm^3. A square piece of aluminum foil, 22.86 cm on a side is found to weigh 2.568 g. What is the thickness of the foil, in millimeters?

Answers

Answer:

0.00182 cm

Explanation:

Area of the aluminum foil = 22.86 cm ×22.86 cm = 522.58 cm^2

Density = mass/area × thickness

Density × area × thickness = mass

Thickness = mass/ Density × area

Thickness = 2.568 g/2.70 g/cm^3 × 522.58 cm^2

Thickness= 0.00182 cm

5. When an electric current is passed through water during the process of electrolysis, two gases are formed. One gas has a boiling point of -183°C and the other has a boiling point of -253ºC. Was this event a physical
change or a chemical change?
It was a chemical change.
It was both a chemical and physical change
It was a physical change
It could have been either a physical or chemical change.

Answers

Answer:

Change is happening all around us all of the time. Just as chemists have classified elements and compounds, they have also classified types of changes. Changes are classified as either physical or chemical changes. Chemists learn a lot about the nature of matter by studying the changes that matter can undergo. Chemists make a distinction between two different types of changes that they study—physical changes and chemical changes.

How much energy is needed to heat 40.5g of water from 15.6°C to 73.0°C

Answers

Answer:

9717.246 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) of water = 40.5 g

Initial temperature (T₁) = 15.6 °C

Final temperature (T₂) = 73 °C

Specific heat capacity (C) of water = 4.18 J/gºC

Heat (Q) =.?

Next, we shall determine the change in the temperature of water. This can be obtained as follow:

Initial temperature (T₁) = 15.6 °C

Final temperature (T₂) = 73 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 73 – 15.6

ΔT = 57.4 °C

Finally, we shall determine the heat energy required. This can be obtained as follow:

Mass (m) of water = 40.5 g

Specific heat capacity (C) of water = 4.18 J/gºC

Change in temperature (ΔT) = 57.4 °C

Heat (Q) =.?

Q = MCΔT

Q = 40.5 × 4.18 × 57.4

Q = 9717.246 J

Thus, the heat energy required is 9717.246 J

6- A favorable condition for two elements to form an ionic bond is?
a- both should be electronegative
b- one should have low electron affinity and the other low ionization energy.
C- one should have high electron affinity and the other low ionization energy.
d- both should be highly electronegative​

Answers

Answer: C- one should have high electron affinity and the other low ionization energy.

Explanation:

Ionization energy is the energy required to remove the electron from an isolated gaseous atom.

Electron affinity is the tendency of an isolated atom to attrcat the electrons towards itsellf.

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and it can donate electron easily if it has low ionization energy.

The element which accepts the electrons is known as electronegative element or non metal and it can easily accept the electron if it has high electron affinity.

What is the mass of .89 moles of lithium metal, used in laptop batteries?

Answers

6.17749 would be the mass

The mass of lithium metal that is used in lithium batteries is 6.17 grams,  this can be calculated by using number of moles formula.

Number of moles:

It is defined as the ratio between mass and molar mass.

It is given by:

Number of moles = mass / Molar mass

What information do we have?

Number of moles= 0.89 moles

Molar mass of Lithium metal= 6.941 g/mol

To find:

Mass of Lithium metal=?

On substituting the values

n= m/M

0.89 = m/ 6.941

m= 0.89*6.941

m= 6.177 grams

Thus, the mass of lithium metal is 6.177 grams.

If the density of a certain oil is 0.8gcm3. What is the mass of 10 cm3 sample of this oil?
report your answer with one significant figure.

Answers

Taking into account the definition of density, the mass of the sample of oil with a volume of 10 cm³ and a density of 0.8 [tex]\frac{g}{cm^{3} }[/tex]  is 8 grams.

Definition of density

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Mass of the sample of oil

In this case, you know that:

Density= 0.8 [tex]\frac{g}{cm^{3} }[/tex]Volume= 10 cm³

Replacing in the definition of density:

[tex]0.8 \frac{g}{cm^{3} } =\frac{mass}{10 cm^{3} }[/tex]

Solving:

mass=  0.8 [tex]\frac{g}{cm^{3} }[/tex] × 10 cm³

mass= 8 g

In summary, the mass of the sample of oil with a volume of 10 cm³ and a density of 0.8 [tex]\frac{g}{cm^{3} }[/tex]  is 8 grams.

1. Given that the electronegativity of sulfur (S) is 2.5 and that of silicon (Si) is 1.8, which of the following best describes the chemical bonding in silicon monosulfide (SiS)?

B. nonpolar covalent: equal sharing of electrons between silicon and sulfur
C. polar covalent: electrons shared between silicon and sulfur but attracted more to the sulfur
D. polar covalent: electrons shared between silicon and sulfur but attracted more to the silicon

2. Which of the following is a molecular compound?

A. Mg3N2
B. NH3
C. AlCl3
D. LiBr

3. Potassium (K) reacts with a certain nonmetallic element (Z) to form a compound with the general formula KZ; where element Z is a diatomic gas at room temperature. What is element Z?

A. Oxygen
B. Fluorine
C. Nitrogen
D. Hydrogen

Answers

Answer: 1.  C. polar covalent: electrons shared between silicon and sulfur but attracted more to the sulfur

2. B)  [tex]NH_3[/tex]

3. B) Fluorine

Explanation:

1. A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Electronegativity difference = electronegativity of sulphur- electronegativity of silicon = 2.5 -1.8 = 0.7

Thus as electronegativity difference is less than 1.7 , the cond is polar covalent and as electronegativity of sulphur is more , the electrons will be more towards sulphur.

2. A molecular compound is usually composed of two or more nonmetal elements. Example: [tex]NH_3[/tex]

Ionic compound is formed by the transfer of electrons from metals to non metals. Example: [tex]Mg_3N_2[/tex] , [tex]AlCl_3[/tex] and [tex]LiBr[/tex]

3.  For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here K is having an oxidation state of +1 and as the compound formed is KZ, the oxidation state of non metallic element Z should be -1. Thus the element Z is flourine which exists as diatomic gas [tex]F_2[/tex]

A. 6.19
B. 12.29
C. 18.29
D. 36.69

Answers

Answer:

Mass = 18.29 g  

Explanation:

Given data:

Mass of beryllium needed = ?

Mass of nitrogen = 18.9 g

Solution:

Chemical equation:

3Be + N₂    →    Be₃N₂

Number of moles of nitrogen:

Number of moles = mass/molar mass

Molar mass of nitrogen = 28 g/mol

Number of moles = 18.9 g/ 28 g/mol

Number of moles = 0.675 mol

Now we will compare the moles of nitrogen and Be.

                       N₂        :       Be        

                        1          :       3

                   0.675       :      3/1×0.675 = 2.03 mol

Mass of Be:

Mass = number of moles × molar mass

Mass = 2.03 mol ×   9.01 g/mol

Mass = 18.29 g

Explanation:

Mixtures are impure substances.

There are two types of mixtures based on the number of coexisting phases.

Homogeneous mixtures have their constituents existing in one single phase. The components are evenly spaced.

Heterogeneous mixtures have their constituents existing in at least two different phases. Therefore, they are unevenly spaced due to the phases present within the mixture.
