What is the name for Si3S

Answer:

0.03 L

Explanation:

Step 1: Given data

Step 2: Calculate the final volume of the balloon

The balloon is filled with air. If we assume it behaves as an ideal gas, we can calculate the final volume of the balloon using Charles' law.

V₁/T₁ = V₂/T₂

V₂ = V₁ × T₂/T₁

V₂ = 0.5 L × 20 K/293 K = 0.03 L

Answer:

160.000 años corresponde a 16.000 décadas.

Explanation:

Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:

1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?

1 década→10 años

          x    ←160.000 años

Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;

x=([tex]\frac{160.000x1}{10}[/tex])=16.000 décadas; en notación científica sería 16x10^3.

Respuesta: 160.000 años corresponde a 16.000 décadas.

Answer:

[tex]P_{Ar}=7.068mmHg[/tex]

Explanation:

Hello!

In this case, according to the given percent of argon in our atmosphere, it is possible to compute the pressure contributed by it as shown below:

[tex]P_{Ar}=P_{atm}*0.93\%[/tex]

Thus, we plug in to obtain:

[tex]P_{Ar}=760mmHg*0.0093\\\\P_{Ar}=7.068mmHg[/tex]

Best regards!

The pressure of the argon gas will be equal to [tex]P_{Ar}=7.068 \rm\ mmHg[/tex]

Pressure is defined as the normal force acting on any surface in the case of gases it is the normal force acting on the surface of the earth.

now it is given in the question that the Argon contains 0.93%  part in the atmosphere.

So here are the calculations

[tex]\rm P_{Ar}=P_{Atm}\times 0.93[/tex]%

[tex]\rm P_{Ar}=700\times 0.93[/tex]%

[tex]\rm P_{Ar}=7.068\ mmHg[/tex]

Thus the pressure of the argon gas will be equal to [tex]P_{Ar}=7.068 \rm\ mmHg[/tex]

Answer:

A

Explanation:

Answer:

6.52×10⁴ GHz

Explanation:

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

Wavelength (λ) = 4.6 μm

Velocity of light (v) = 2.998×10⁸ m/s

Frequency (f) =?

Next we shall convert 4.6 μm to metre (m). This can be obtained as follow:

1 μm = 1×10¯⁶ m

Therefore,

4.6 μm = 4.6 μm × 1×10¯⁶ m / 1 μm

4.6 μm = 4.6×10¯⁶ m

Next, we shall determine frequency of the light. This can be obtained as follow:

Wavelength (λ) = 4.6×10¯⁶ m

Velocity of light (v) = 2.998×10⁸ m/s

Frequency (f) =?

v = λf

2.998×10⁸ = 4.6×10¯⁶ × f

Divide both side by 4.6×10¯⁶

f = 2.998×10⁸ / 4.6×10¯⁶

f = 6.52×10¹³ Hz

Finally, we shall convert 6.52×10¹³ Hz to gigahertz. This can be obtained as follow:

1 Hz = 1×10¯⁹ GHz

Therefore,

6.52×10¹³ Hz = 6.52×10¹³ Hz × 1×10¯⁹ GHz / 1Hz

6.52×10¹³ Hz = 6.52×10⁴ GHz

Thus, the frequency of the light is 6.52×10⁴ GHz

Answer:

Number of protons in Carbon - 14 atom [tex]6[/tex]

Explanation:

The atomic number of carbon 14 atom is [tex]14[/tex]

Number of neutrons in the nucleus of Carbon-14 atom [tex]= 8[/tex]

Atomic number is equal to the sum of neutrons and protons

Number of protons in Carbon - 14 atom [tex]= 14 -8 = 6[/tex]

These are reactions that transfer energy to the surroundings (ie the energy exits from the reaction, hence the name exothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase.

Examples:

Combustion

Neutralisation between acids and alkali

These are reactions that take in energy from the surroundings (ie energy enters the reaction, which will help you to remember the name endothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become colder. A thermometer is used to detect the temperature decrease.

Answer:

Mean: 350

Median: 300

Range: 650

Mode: 300

Explanation:

Mean: 800+300+150+300+200= 1750, 1750 divided by 5 = 350

You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS to find the mean.

Median: (150, 200, 300, 300, 800)

To find Median put the numbers in order from greatest to least then you choose the middle number.

Range: Range is the distance from the smallest number to the largest the way to solve this is (Highest number) - (lowest number). In your case its 800-150 which equals 650

Mode: The mode is the value that appears most frequently in a data set.

Answer:

1.00 mol

Explanation:

Step 1: Given data

Molecules of water: 6.02 × 10²³ molecules

Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water

In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)

I have understood that the meaning of life is to have a vision and live a purposeful life.

Living a meaningful life is concerned about the essence of waking up everyday and having something meaningful that you're doing or engaging yourself into what you have vision about.

Life is good and lively when you have a vision, this vision is drive by a passion for a particular thing. When you're visionary, you will be happy every day and it is visionaries that change the world positively.

Over an extended period of time, this vision will be brought into life where people can benefit from it. Here, is where purpose comes in.

Answer:

Ionic bonding is the attraction between positively- and negatively-charged ions. These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel.

Explanation:

Ionic compounds form because opposite charges attract.

In an ionic compound, positive and negative ions come together to form a stable structure. This occurs when an atom loses electrons to become a positively charged ion (cation) and another atom gains those electrons to become a negatively charged ion (anion). The positive and negative charges of the ions attract each other, resulting in the formation of an ionic bond.

This attraction between positive and negative charges is what holds ionic compounds together. The strong electrostatic forces of attraction between ions result in a lattice structure, where each ion is surrounded by oppositely charged ions.

Thus, ionic compounds are formed because opposite charges attract.

Answer:

Not exactly But you can take the slope of the curved portion and the slope of the flatline.

It wont do you much good since your working for absorbance but if you ever see something like a temperature change you can use the slope(s) to find freezing points/melting

If you need to submit a slope you could use a best fit which is just point to point or you could break it up like i mentioned

Answer:

increase

Explanation:

Reactions that are initiated by light are called photochemical reactions. The brighter the light, the faster the reaction.

Answer: An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
