why do the Noble gases have the highest ionization energies across a period?

Answers

Answer 1

Answer:

ionization energy decreases from top to bottom in groups, and increases from left to right across a period. So technically, the noble games have the largest ionization energy.

How much energy is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C? (Refer to table of specific heat values.)​

Answers

the answer is B. 538J

The amount of energy which  is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C is 49,545 J.

How do we calculate absorbed energy?

Amount of energy absorbed by any material will be calculated by using the below equation:

Q = mcΔT, where

m = mass of aluminum = 0.2 kg

c = specific heat of aluminum = 897 J/kg.K

ΔT = change in temperature = 18 - 15 = 3°C = 276.15 K

On putting these value on the above equation, we get

Q = (0.2)(897)(276.17) = 49,544.89 = 49,545 J

Hence required amount of energy is 49,545 J.

Answer:

A. a rotten potato gives all of bad smell

Explanation:

B,C,D are all physical changes because we can reverse them back.we can cool the water back to make ice. if the wind passes again we can randomly get the same cloud shape in c. and in d we can make that statue again. but in A can we reverse the rotting process ? ( the enzyme reaction) no we cant because it is a chemical reaction it gives a bad smell because of the chemical changes occuring in it.

What are the two parts of an atom ?

Answers

Answer:

The nucleus and the outer region.

Explanation:

Determine the pressure of a 6.4L sample of oxygen gas at 300K and 100KPa, after the gas is compressed to 2.40L at 900K.

Answers

The pressure : 800 kPa

Further explanation

Boyle's law and Gay Lussac's law  

[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]

P1 = initial gas pressure (N/m² or Pa)  

V1 = initial gas volume (m³)  

P2 = gas end pressure  

V2 = the final volume of gas  

T1 = initial gas temperature (K)  

T2 = gas end temperature  

The pressure after the gas is compressed :

[tex]\tt \dfrac{100\times 6.4}{300}=\dfrac{P_2\times 2.4}{900}\\\\P_2=800~KPa[/tex]

Explain how Earth is heated through radiation

Answers

Answer:

Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.

Determine the mass of 2.86 mole Co(NH3)6Cl3

Answers

Answer:

765 g Co(NH₃)₆Cl₃

General Formulas and Concepts:

Reading the Periodic Table of Elements

Explanation:

Step 1: Define

2.86 mol Co(NH₃)₆Cl₃

Step 2: Define conversions

Molar Mass of Co - 58.93 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol

Step 3: Dimensional Analysis

[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃

mol Co(NH₃)₆Cl₃ and mol Co(NH₃)₆Cl₃ cancel outWe are left with grams (mass)

Step 4: Simplify

We are given 3 sig figs. Follow sig fig rules.

765.107 g Co(NH₃)₆Cl₃ ≈ 765 g Co(NH₃)₆Cl₃

If you wanted to change the polarity of hydrogen bromide (HBr) by substituting the bromine by a different atom. Which atom would increase the polarity of the molecule?

Answers

Answer:

Chlorine

Explanation:

The Polarity of an atom is characterized as the dipole to dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule. Thus, the 'chlorine' atom would help in enhancing the polarity of hydrogen bromide(HBr) with 3.16 electronegativity as we know, the electronegativity increases if we move upwards in the periodic table.

Green light has a frequency of 6.01 x 10^14 Hz. What is the wavelength? (Round to the nearest hundredth) *​

Answers

Answer:

4.99 x 10⁻⁷ meters or 499 nanometers

Explanation:

Use the formula:

λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency

λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)

λ = 4.98835 x 10⁻⁷

Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.
