Answer:
Explanation:
Hello,
In this case, we define the entropy change for such freezing process as:
Thus, we compute the moles that are in 5.590 g of liquid mercury:
Hence, we compute the required entropy change, considering the temperature to be in kelvins:
Best regards.
Answer:
Cost of silk was too high
Explanation:
The major reason of not using silk as a fabric in the hot air balloons was high cost of silk. Due to its high cost, silk became unaffordable for use in modern balloon.
If cost is neglected, then silk is the perfect material for hot air balloon as it is light in weight
What are the statements? A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction
Answer:
products
Explanation:
In chemistry, chemical reactions is the combination of two or more substances to yield other substances. The substances that react is called REACTANTS while the substances formed after the reaction is called PRODUCTS.
According to this question, a mixture of oxygen and hydrogen is ignited in a test tube as follows:
Hydrogen + Oxygen → Water + Energy
In this reaction, the substances being combined (usually found on the left side of the equation) are hydrogen and oxygen. Hence, oxygen and hydrogen are REACTANTS. Also, the substances produced as a result of the reaction is water (H2O). The PRODUCTS of the reaction is WATER.
