Answers

Answer 1

Answer:

2.39×10¯⁵ m²

Explanation:

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

Distance (d) = 8.08×10¯⁵ m

Charge (q) = 2.24×10¯⁹ C

Potential difference = 855 V

Area(A) =?

NOTE: Permittivity (ε₀) = 8.854×10¯¹² F/m

The area can be obtained as follow:

q = ε₀AV/d

2.24×10¯⁹ = 8.854×10¯¹² × A × 855 / 8.08×10¯⁵

2.24×10¯⁹ = 7.57×10¯⁹ × A / 8.08×10¯⁵

Cross multiply

7.75×10¯⁹ × A = 2.24×10¯⁹ × 8.08×10¯⁵

7.75×10¯⁹ × A = 1.81×10¯¹³

Divide both side by 7.75×10¯⁹

A = 1.81×10¯¹³ / 7.75×10¯⁹

A = 2.39×10¯⁵ m²

Thus, the area of the plate is 2.34×10¯⁵ m²

What is the concentration of a solution made by combining 52 grams of NaCH3COO with 150 mL of water?

Answers

Answer: The concentration of a solution made by combining 52 grams of  [tex]NaCH_{3}COO^{-}[/tex] with 150 mL of water is 4.22 M.

Explanation:

Given: Mass = 52 grams

Volume = 150 mL (1 mL = 0.001 L) = 0.150 L

Molarity is the number of moles of a substance present in liter of a solution.

And, moles is the mass of a substance divided by its molar mass.

Hence, moles of [tex]NaCH_{3}COO^{-}[/tex] (molar mass = 82.034 g/mol) is as follows.

[tex]Moles = \frac{mass}{molar mass}\\= \frac{52 g}{82.034 g/mol}\\= 0.633 mol[/tex]

Therefore, concentration of given solution is as follows.

[tex]Molarity = \frac{moles}{Volume(in L)}\\= \frac{0.633 mol}{0.150 L}\\= 4.22 M[/tex]

Thus, we can conclude that the concentration of a solution made by combining 52 grams of  [tex]NaCH_{3}COO^{-}[/tex] with 150 mL of water is 4.22 M.

If the power source in a motor was to be replaced with an electrical load, and the armature was turned by hand, then what device have you made?

Answers

Answer:

This question doesnt make much sense but ill try to answer it.

A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially important application of electricity. If the shaft of a DC motor is turned by an external force, the motor will act as a generator. DC Motor rotation does have to do with the voltage polarity and the direction of the current flow.

A reaction requires 22.4 L of gas at STP . There are 25.0 L of gas at 101.5 kPa and 373 K.

Which statement is true?

Use the ideal gas law: PV = nRT where R = 8.31 L-kPa/mol-K

A. There is not enough gas for the reaction.

B. Given this information, there is no way to tell if there is enough gas for the reaction.

C. There is excess gas for the reaction.

D. There is enough gas for the reaction.

Answers

Answer:

STP is 101.325 kPa pressure and 273K temperature

Also, at STP, 1 mol of an ideal gas = 22.4 L

Since the question states that 22.4 L are needed at STP, we know that ONE MOLE is needed.  Now, the question is, how many moles are actually present?

V = 25.0 L

P = 101.5 kPa

T = 373K

n = ?

R = 8.31 L-kPa/Kmol

Solving the ideal gas law for n (moles) and comparing that to 1 mole, we have...

n = PV/RT = (101.5)(25.0)/(8.31)(373)

n = 0.82 moles of gas.  THIS IS NOT ENOUGH as it is less than the ONE mole required.

How many milliliters of 1.5 M H.So, are needed to exactly
neutralize 20. milliliters of a 0.8 M KOH solution?

Answers

Answer: A volume of 10.66 mL of 1.5 M H is required to exactly neutralize 20. milliliters of a 0.8 M KOH solution.

Explanation:

Given: [tex]M_{1}[/tex] = 1.5 M,     [tex]V_{1}[/tex] = ?

[tex]V_{2}[/tex] = 20 mL,         [tex]M_{2}[/tex] = 0.8 M

Formula used to calculate the volume is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\1.5 M \times V_{1} = 0.8 M \times 20 mL\\V_{1} = 10.66 mL[/tex]

Thus, we can conclude that a volume of 10.66 mL of 1.5 M H is required to exactly neutralize 20. milliliters of a 0.8 M KOH solution.

what are some different natural events and man-made activities that can affect ocean acidification?

Answers

Some man made events are activities that include the burning of fossil fuels, deforestation and vehicle emissions.
Natural events are earthquakes,floods, wildfires

Ocean acidification is the process of decreased pH levels of the oceans. The burning of fossil fuels and industrialization are man-made activities that lead to this process.

What is Ocean acidification?

Ocean acidification is an increased concentration of acidic components of the oceans due to an increase in the carbon dioxide level of the oceans.

Human activities like cutting down a large number of trees, discharging from industrial outlets, and burning fossils like petrol, coal, diesel, etc. are leading to increased acidification of the oceans.

Therefore, natural causes like increased salinity, flood, and earthquake are the reasons for oceanic acidification.

Based on your understanding of how bond types influence a material’s properties, identify each of the following compounds as being made of ionic, covalent, or metallic bonds.
ANSWER
Steel: Metalic
Propane: Covalent
Calcium chloride: ionic
Water: Covalent
Edge 2021

Answers

Answer: The given compounds are identified as being made of ionic, covalent, or metallic bonds:

Steel - Metallic bondsPropane - Covalent bondsCalcium chloride - Ionic bondsWater - Covalent bonds

Explanation:

A bond formed by transfer of electrons from one atom to another is called an ionic bond. An ionic bond is formed between a metal atom and a non-metal atom.

A bond formed by transfer of electrons from one atom to another is called a covalent bond. A covalent bond is formed between two or more non-metal atoms only.

Steel is actually an alloy of carbon and iron where there is less than 2% carbon, 1% manganese and small amounts of silicon, phosphorus, oxygen and sulphur are present.

When atoms of metals are held together then bond formed between these atoms is called metallic bond.

Hence, steel is made of metallic bond.

Chemical formula of propane is [tex]CH_{3}CH_{2}CH_{3}[/tex] as there are only non-metal atoms are present. So, sharing of electrons takes place in such atoms due to which covalent bonding will be there.

Hence, propane is made up of covalent bonds.  

Calcium chloride contains a metal and a non-metal atom. This means that electrons are being transferred from calcium atom to the chlorine atom. Hence, bond present in calcium chloride is ionic bond.

Water has chemical formula [tex]H_{2}O[/tex]. Since, non-metal atoms are present there so sharing of electrons takes place between hydrogen and oxygen atoms. Hence, covalent bond is present in water.

Thus, we can conclude that given compounds are identified as being made of ionic, covalent, or metallic bonds:

Steel - Metallic bondsPropane - Covalent bondsCalcium chloride - Ionic bondsWater - Covalent bonds

Steel: ✔ metallic

Propane: ✔ covalent

Calcium chloride: ✔ ionic

Water: ✔ covalent

What unit is used for atomic mass

Answers

Please mark brainliedt

Answer is daltons
Atomic weight is measured in atomic mass units (amu), also called daltons.




Atomic Mass

Masses of individual atoms are very, very small. Using a modern device called a mass spectrometer, it is possible to measure such minuscule masses. An atom of oxygen-16, for example, has a mass of 2.66 × 10 -23 g. While comparisons of masses measured in grams would have some usefulness, it is far more practical to have a system that will allow us to more easily compare relative atomic masses. Scientists decided on using the carbon-12 nuclide as the reference standard by which all other masses would be compared. By definition, one atom of carbon-12 is assigned a mass of 12 atomic mass units (amu). An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of any isotope of any element is expressed in relation to the carbon-12 standard. For example, one atom of helium-4 has a mass of 4.0026 amu. An atom of sulfur-32 has a mass of 31.972 amu.

Atoms of H = 4

Atoms of S = 2

Atoms of O = 6

On the product side:

Atoms of H = 2

Atoms of S = 1

Atoms of O = 3

A. n=C x V
B. C=V x n
C. C=n x V
D. n=C / V

Answers

Answer:

A. n= C x V

Explanation:

Molarity of a solution is the molar concentration of that solution. It can be calculated using the formula:

M = n/V

Where;

M = molarity (M)

n = number of moles (n)

V = volume (mL)

To calculate the number of moles from a given molarity value and volume, we say:

n = M × V

For this case of NH4Cl;

V = 500mL = 500/1000 = 0.5L

M = 0.300 M

n = 0.300 × 0.5

n = 0.15moles
