In determining nuclear binding energy, what is Einstein's equation used to do?

Chemistry
1 answer:
natita [175]3 years ago
3 0
Basically this is used in calculating the nuclear binding energy by converting the mass defect (calculated first) to energy and if we recall, Einstein's equation E=mc2 is the perfection equation to use because E=mc2 in which E represents units of energy, m represents units of mass, and c 2 is the speed of light squared.

An unknown gas diffuses 1.25 times faster than CO2 gas. What is the molar mass of the unknown gas?​
hodyreva [135]

Answer:

28.16 g/mol

Explanation:

From Graham's law;

Let the rate of diffusion of gas X be 1.25

Let the rate of diffusion of CO2 be 1

Molecular mass of gas X= M

Molecular mass of CO2 = 44g/mol

1.25/1=√44/M

(1.25/1)^2 = 44/M

1.5625 = 44/M

M= 44/1.5625

M= 28.16 g/mol

How many grams of CO2 gas are produced if 48<br> grams of CH4 gas are consumed?
NNADVOKAT [17]

Answer:

CH4 +2 O2 — CO2 +2 H2O

Now we see that for 1 mol i.e. 16 grams of methane results in 1 mol of CO2 or 44 grams of CO2.

That means for 3 moles of methane , we will obtain 3 moles of CO2 OR for 48 (3*16) grams of CO2 , we will obtain (44*3) 132 grams of CO2 .That's it….

hey .dude hope the answer was helpful ....

‘By using displacement reactions it is possible to deduce the order of reactivity of the halogens.’
Rashid [163]

Answer:

Explanation:

The halogens have seven electrons in their outermost shell. Each halogen atom lacks a single electron to make their octet a complete one. Elements in the halogen group are univalent and also acceptors of electrons. They are all non-metals and oxidizing agents. The oxidizing power of the halogens decreases from top to down the group. This is why the more powerful halogens displaces a less powerful one from simple salts.

         Cl₂ + 2KBr → 2KCl + Br₂

         Cl₂ + 2KI → 2KCl + I₂

          Br₂ + 2KI → 2KBr + I₂

          I₂ + 2KCl → No reaction
