Answer:
Mass, m = 7.97 grams
Explanation:
We have,
Initial temperature was 34 degrees Celsius
Heat produced in it is 100 calories of heat
The specific heat capacity of water is 4.18 J/g °C
The heat produced due to change in temperature is given by :
m is mass of water in grams
So, 7.97 grams of water is required to produce heat of 2200 joules.
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.

The first one shows greater amplitude because there is more space between the waves. The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.
Answer:
The answer is "
"
Explanation:
When 
is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:
In this, the 
is a weak acid so, it not completely dissociated.
were strong electrolytes they are completely dissociated.
The 
is a strong acid so, it is completely dissociated So, the net ionic equation is:
