Answer:
264 g/mol
Explanation:
#electrons equal #protons = 106
Plus 1 charge => m protons = 106 + 1 = 107
Mass number: 107 + 157 = 264 g/mol
Answer:
5/3 moles
Explanation:
3.moles.of H2 gives 3 moles of NH3
so 2.5 moles gives 5/3 moles.
Note:Apply simple. concept of unitary method.
If the intermolecular forces in a liquid<span> are small, the molecules can easily escape from the surface of the</span>liquid<span>. The </span>liquid<span> will have a high </span>vapour pressure<span>. The normal </span>boiling point<span> is the temperature in which the </span>vapour pressure of a liquid<span> becomes equal to atmospheric </span>pressure<span>.</span>
The formula to convert from Celsius to Fahrenheit is F = 9/5C + 32 or F = (C*1,8)+32
F = 9/5*39 + 32 = 70,2 + 32 = 102,2° F
Answer:
Fossil fuels are still the number primary way to harness power because we know how to do it very well and it cost less than other any other way to harness energy
