Answer:
Hypothesis is a predictive statement which relates two or more phenomena.
It is tested to observe or to see whether it is true or false with the help of scientific means.
it relates dependent and independent factors with each other
Theory is a tested and proved framework which explains single or multiple observed phenomena
It is thoroughly proved and tested through experiments and observations.
it is strongly supported by scientific evidences and observations.
Hence, a hypothesis is a prediction for a specific situation, while a theory is used to make predictions for many similar situations.

This information confirms that temperature and solubility are related. The higher the temperature is, the more soluble.
Molar mass :
Cl₂ = 71.0 g/mol Na = 23.0 g/mol
<span>2 Na + Cl</span>₂<span> = 2 NaCl
</span>
2 x 23 g Na -------> 71.0 g Cl₂
96.6 g Na ----------> ?
Mass Cl₂ = ( 96.6 x 71.0 ) / ( 2 x 23 )
Mass Cl₂ = 6858.6 / 46
= 149.1 g of Cl₂
hope this helps!
Answer:
There is 54.29 % sample left after 12.6 days
Explanation:
Step 1: Data given
Half life time = 14.3 days
Time left = 12.6 days
Suppose the original amount is 100.00 grams
Step 2: Calculate the percentage left
X = 100 / 2^n
⇒ with X = The amount of sample after 12.6 days
⇒ with n = (time passed / half-life time) = (12.6/14.3)
X = 100 / 2^(12.6/14.3)
X = 54.29
There is 54.29 % sample left after 12.6 days
