A because cation is positive and anion is negative evening it out at constant.
A synthesis would be A+B-->AB its combining, decomposition is AB-->A+B, its the breaking up of a substance.
1 mole of steam (H2O) = 18g
Heat evolved = MCФ where m is the mass and c s specific heat capacity while Ф is change in temperature. Latent heat of fusion is 334 kj/kg while latent heat of vaporization is 2260 kj/kg and specific heat of water is 4.2 j/g/c
= 18 ×2.01 × (135-100) = 1266.3 J
0.018 × 334000 = 6012 J (change of state from gas (steam) to liquid (water)
18 × 4.186× (100 -0) = 7534.8 J
0.018 × 2260000 = 40680 J (change of state from liquid to solid ice)
18 × 2.09 × (0--45) = 1692.9 J
The total heat evolved is therefore 57186 J or 57.186 kJ
The relationship between hypotheses, laws and theories is that a law is used to explain hypothesis and theories.
<h3>What is a law, a theory and hypothesis?</h3>
A hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further investigation or experimentation.
A theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.
A law is a statement whose sequence or relationship of phenomena is invariable under certain conditions.
This suggests that a law can be used to explain a theory and hypothesis.
