E = m c²

where E = energy released

m = mass of the nucleus

C= velocity of light

m = 9.106 x 10⁻³ x 1.67 x 10⁻²⁷ kg

C = 3 x 10⁸ m/s and C² = 9 x 10¹⁶

E = 1.37 x 10 ⁻¹² J

Answer : The amount of energy released is, 136.043\times 10^{-14}J

Explanation :

According to the Einstein equation, the energy is equal to the product of mass and the square of the speed of light.

The mathematical expression is :

E=m\times c^2

where,

E = energy

c = speed of light = 3\times 10^8m/s

m = mass of nucleus = 9.106\times 10^{-3}amu

Conversion the mass of nucleus from 'amu' into 'Kg' :

As, 1amu=1.66\times 10^{-27}Kg

So, 9.106\times 10^{-3}amu=(9.106\times 10^{-3})\times (1.66\times 10^{-27})Kg

Now put all the given values in the above formula, we get the amount of energy released.

E=[(9.106\times 10^{-3})\times (1.66\times 10^{-27})Kg]\times (3\times 10^8m/s)^2

E=136.043\times 10^{-14}J

Therefore, the amount of energy released is, 136.043\times 10^{-14}J

Which solution contains the largest number of moles of chloride ions?
elixir [45]
Molarity = number of moles of solute/liters of solution
number of moles of solute = molarity x liters of solution

Part (a): <span>30.00 ml of 0.100m Cacl2
number of moles of CaCl2 =  0.1 x 0.03 = 3x10^-3 moles
1 mole of CaCl2 contains 2 moles of chlorine, therefore 3x10^-3 moles of CaCl2 contains 6x10^-3 moles of chlorine

Part (b): </span><span>10.0 ml of 0.500m bacl2
number of moles of BaCl2 = 0.5 x 0.01 = 5x10^-3 moles
1 mole of BaCl2 contains 2 moles of chlorine, therefore 5x10^-3 moles of BaCl2 contains 10x10^-3 moles of chlorine

Part (c): </span><span>4.00 ml of 1.000m nacl
number of moles of NaCl = 1 x 0.004 = 0.004 moles
1 mole of NaCl contains 1 mole of chlorine, therefore 4x10^-3 moles of NaCl contains 4x10^-3 moles of chlorine

Part (d): </span><span>7.50 ml of 0.500m fecl3
number of moles of FeCl3 = 0.5 x 0.0075 = 3.75x10^-3 moles
1 mole of FeCl3 contains 3 moles of chlorine, therefore 3.75x10^-3 moles of FeCl3 contains 0.01125 moles of chlorine

Based on the above calculations, the correct answer is (d)</span>

Consider the picture of a gas pump. Which type of gasoline has the highest percentage of octane (the main component of gasoline)
Readme [11.4K]

Answer:

premium: 91 octane rating

Explanation:

Octane number refers to the percentage or volume fraction of isooctane in a fuel.

The octane number gives a picture of how safe a fuel is for an engine. The higher the octane rating the lesser the tendency of the fuel to cause knocking of the engine.

The type of gasoline with the highest percentage of octane among the options is premium.

a compound consists of 17.6% of hydrogen and 82.4% nitrogen. Determine the empirical formula of the compound
Wewaii [24]
17,6% + 82,6% = 100%

mass of N = 14g
mass of H = 1g

17,6% H = 17,6g H
82,4% N = 82,4g N

17,6g : 1g = 17,6  moles of H
82,4g : 14g = 5,89 moles of N

N  :  H  =  5,89  :  17,6  ||:5,89
N  :  H  =  1      :   2,99≈3

the empirical formula of the compound = NH₃  (ammonia)
