17. Using the ideal gas law, PV = nRT, in which R is 8.31 (LkPa/mol·K), what would the temperature be if 0.75 moles of helium gas in a 2.0L container have a pressure of 202.65 kPa?
O 540 K
O 9.1K
O 630 K
O 65 K

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
