Answer:

Option B. S

Explanation:

All of the options except sulphur, S is metal.

Metals tend to lose electron in order to form ion. Non metals on the other hand gain electron to form ion.

Sulphur, S has atomic number of 16 with electronic configuration as:

S (16) => 1s² 2s²2p⁶ 3s²3p⁴

From the above illustration, we can see that sulphur needs two more electrons to complete it's octet configuration.

Therefore, sulphur, S will gain two electrons to form ion.

As stated earlier, the rest option given are all metals which will form ion by losing electron(s).

How long would it take to produce enough aluminum to make a case (24 cans) of aluminum soft drink cans if each can used 3 g of a

kozerog [31]

Answer : It takes time to produce 3 g of aluminium is, 165 seconds.

Explanation :

As we are given that the mass of aluminium is, 3 grams. Now we have to calculate the total mass of aluminum.

Total mass of aluminum = 3g × 24 = 72 g

Now we have to calculate the moles of aluminum.

$\text{Moles of Al}=\frac{\text{Mass of Al}}{\text{Molar mass of Al}}$

Molar mass of Al = 27 g/mol

$\text{Moles of Al}=\frac{72g}{27g/mol}=2.67mol$

As, 1 mole of Al has 3 Faradays

So, 2.67 mole of Al has = $2.67\times 3=80.1$ Faradays

and,

Charge = $80.1\text{ Faradays}\times \frac{96500\text{ coulombs}}{1\text{ Faradays}}=7.73\times 10^6\text{ coulombs}$

Current = $5.00\times 10^4A\times \frac{93.9}{100}=46950A$

Now we have to calculate the time.

$Time=\frac{Charge}{Current}=\frac{7.73\times 10^6}{46950}=164.6s\aaprox 165s$

Hence, it takes time to produce 3 g of aluminium is, 165 seconds.

15000 joules is used to heat a 950g piece of metal from 45 degrees Celsius to 78 degrees Celsius what is the specific heat of th

castortr0y [4]

Answer:

0.478 J/g/C

Explanation:

When solving questions on heat energy, we can use the formula

Q = mcT where

Q is the amount of energy supplied in Joules

m is the mass of the object in Grams

c is the specific heat capacity of the metal in Joules Per Gram Per Degree Celcius

T is the change in Temperature in Degree Celcius.

So by applying the formula to this question, we get:

15000 = (950)(c)(78 -45)

c = 0.478 J/g/C

At 32 C the pressure inside a nitrogen-filled tennis ball either the volume of 0.148L is 212 kPa. How many moles of nitrogen gas

IgorLugansk [536]

Answer:

The number of moles of nitrogen gas in the tennis ball is 0.0124 moles

Explanation:

Here we have the universal gas equation as

P·V = n·R·T

Where:

P = Pressure of the gas = 212 kPa

V = Volume of the gas = 0.148 L = ‪0.000148‬ m³

n = Number of moles

R = Universal gas constant = 8.3145 J / mol·K.

T = Temperature of the gas in Kelvin = 32 + 273.15 = 305.15 K

Therefore,

$n = \frac{P \cdot V}{R \cdot T} = \frac{212000 \times 0.000148}{8.3145 \cdot 305.15}= 0.0124 \ moles$

The number of moles of nitrogen gas in the tennis ball = 0.0124 moles.
