A fluorinated organic gas in a cylinder is compressed from an initial volume of 910 mL at 154 Pa to 492 mL at the same temperature.
What is the final pressure?
Answer in units of Pa.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

answer; talc and gypsum;

elements make up everything, and they combine to make compounds.

the answer is c

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
