An acid is an ionic compound that produces positive hydrogen ions when dissolved in water. Acids taste sour and turn blue litmus paper red. A base is an ionic compound that produces negative hydroxide ions when dissolved in water. Bases taste bitter and turn red litmus paper blue.
Yes, when molten candle wax solidifies it is a chemical reaction
<u>Explanation:</u>
Basically Wax is crystalline so once the candle light melts it freezes taking back the solid state to the room temperature.
When the room temperature is below the freezing point, the liquid candle wax, turns into solid state again, therefore this process is called solidification. The process of freezing or solidification is a process when an object turns liquid and freezes back to solid state.
Indeed, Yes, when molten candle wax solidifies it is a chemical reaction
The molecular formula for Hydrocarbon = C₄H₁₀
<h3>
Further explanation:</h3>
Given
50 ml hydrocarbon
200 ml CO₂
250 ml H₂O
Required
The molecular formula of Hydrocarbon
Solution
From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
So moles Hydrocarbon : CO₂ : H₂O = 50 ml : 200 ml : 250 ml = 1 : 4 : 5
mol C in 1 mol CO₂=1, and for 4 moles CO₂ there are 4 moles C
mol H in 1 mol H₂O =2, and for 5 moles H₂O there are 10 moles H
So mol ratio C : H in compound = C₄H₁₀
The answer is diamagnetism. It is a significant mechanical
effect that happens in all materials; when it is the only influence to the
magnetism, the material is named diamagnetic. Quartz and water are samples
of diamagnetic materials. The diamagnetic influence
is usually unimportant in materials holding strong lasting magnetic moments.
Answer:
d
Explanation:
p is pressure, v is vo;lume, t is temperature, r is ideal gas contstant, therefore n is the moles
