Answer:
The mass of tin is 164 grams
Explanation:
Step 1: Data given
Specific heat heat of tin = 0.222 J/g°C
The initial temeprature of tin = 80.0 °C
Mass of water = 100.0 grams
The specific heat of water = 4.184 J/g°C
Initial temperature = 30.0 °C
The final temperature = 34.0 °C
Step 2: Calculate the mass of tin
Heat lost = heat gained
Qlost = -Qgained
Qtin = -Qwater
Q = m*c*ΔT
m(tin)*c(tin)*ΔT(tin) = -m(water)*c(water)*ΔT(water)
⇒with m(tin) = the mass of tin = TO BE DETERMINED
⇒with c(tin) = the specific heat of tin = 0.222J/g°C
⇒with ΔT(tin) = the change of temperature of tin = T2 - T1 = 34.0°C - 80.0°C = -46.0°C
⇒with m(water) = the mass of water = 100.0 grams
⇒with c(water) = the specific heat of water = 4.184 J/g°C
⇒with ΔT(water) = the change of temperature of water = T2 - T1 = 34.0° C - 30.0 °C = 4.0 °C
m(tin) * 0.222 J/g°C * -46.0 °C = -100.0g* 4.184 J/g°C * 4.0 °C
m(tin) = 163.9 grams ≈ 164 grams
The mass of tin is 164 grams
Explanation:
As it is given that mixture (contains 9 mol % A and 91% B) and it is flowing at a rate of 800 kg/h.
Hence, calculate the molecular weight of the mixture as follows.
Weight = 
= 27.8336 g/mol
And, molar flow rate of air and mixture is calculated as follows.
= 28.74 kmol/hr
Now, applying component balance as follows.
= 43.11 kmol/hr
= 43.11 - 28.74
= 14.37 kmol/hr
So, mass flow rate of pure (B), is = 
= 416.73 kg/hr
According to the product stream, 6 mol% A and 94 mol% B is there.
Molecular weight of product stream = 
= 
= 28.22 g/mol
Mass of product stream = 1216.67 kg/hr
Hence, mole of 
into the product stream is as follows.
= 
= 272.31 kg/hr
Therefore, calculate the mass % of into the stream as follows.
= 22.38%
Thus, we can conclude that the required flow rate of B is 272.31 kg/hr and the percent by mass of in the product gas is 22.38%.
There are two electrons in 4s and 6 in 3d. When you lose 3 electrons, you will be left with an ion of 3+ charge!
Answer:
Ionic bond occurs between two atoms that have different:
a) Electron
Explanation:
according to the definition of ionic bond,
it is the electrostatic force of attraction that holds the two oppositely charged ions together and an ionic bond or electrovalent bond is formed when one atom gains electrons while the other atom loses electrons from its outermost level or orbit.
