At a pressure 42 kPa, the gas in a cylinder has a volume of 18 liters. Assuming temperature remains the same, if the volume of t
irina1246 [14]
The ideal gas law formula is: PV=nRT. As the n(moles of gas), R(Gas constant) and T(temperature) values are constant as it is given in the problem, we can calculate the pressure difference by the following formula: xΔP(difference factor of pressure)=1/xΔV. We can find the difference factor of volume by x=V(0)/v(1),
x=18l/2l=9 which means the pressure is 9 times greater after the volume is down to 2l. To find the final pressure, we can use P(1)=xP(0), when we add the numbers in, it looks like this: P(1)=9*42 kPa=378 kPa

What is the ratio of Fe3+ ions to O2- ions in a neutral compound?<br> 1:2<br> 2:1<br> 2:3<br> 3:2,
Lera25 [3.4K]
<span>The answer is 2:3. Because the lowest common denominator of 2 and 3 is 6, we find that for every 2 Fe3+ ions, we would need 3 O2- ions to neutralize the charge. The other answers do not fit this idea, as the math doesn't then add up to come to a neutral charge.</span>

What are some chemical and physical properties of soap (saponification) please help it’s very urgent!
xxTIMURxx [149]

Answer: Soaps are sodium or potassium fatty acids salts, produced from the hydrolysis of fats in a chemical reaction called saponification. Each soap molecule has a long hydrocarbon chain, sometimes called its 'tail', with a carboxylate 'head'.

Explanation: Saponification is an exothermic chemical reaction—which means that it gives off heat—that occurs when fats or oils (fatty acids) come into contact with lye, a base. In this reaction, the triglyceride units of fats react with sodium hydroxide or potassium hydroxide and are converted to soap and glycerol.
