Answer:

Explanation:The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century. It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses, via induction, based on such observations; experimental and measurement-based testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises.[1][2][3]

Though diverse models for the scientific method are available, there is in general a continuous process that includes observations about the natural world. People are naturally inquisitive, so they often come up with questions about things they see or hear, and they often develop ideas or hypotheses about why things are the way they are. The best hypotheses lead to predictions that can be tested in various ways. The most conclusive testing of hypotheses comes from reasoning based on carefully controlled experimental data. Depending on how well additional tests match the predictions, the original hypothesis may require refinement, alteration, expansion or even rejection. If a particular hypothesis becomes very well supported, a general theory may be develope

How many moles of water will be produced when 15.0 g of calcium chloride dihydrate are heated ?
Vanyuwa [196]

Answer:

0.204 mol

Explanation:

Step 1: Write the balanced equation for the heating of calcium chloride dihydrate

CaCl₂.2H₂O ⇒ CaCl₂ + 2H₂O

Step 2: Calculate the moles of calcium chloride dihydrate

The<em> molar mass of CaCl₂.2H₂O</em> is 147.01 g/mol. The moles corresponding to 15.0 g of CaCl₂.2H₂O are:

15.0g \times \frac{1mol}{147.01g} = 0.102 mol

Step 3: Establish the molar ratio of CaCl₂.2H₂O to H₂O

According to <em>the balanced equation</em>, the molar ratio of CaCl₂.2H₂O to H₂O is 1:2.

Step 4: Use the molar ratio to calculate the moles of water produced from 0.102 moles of calcium chloride dihydrate

0.102molCaCl_2.2H_2O \times \frac{2molH_2O}{1molCaCl_2.2H_2O} = 0.204molH_2O
