Calculate the number of moles of CO2 by the formula n=PV/RT, where P is the pressure from Step 3, V is the volume from Step 2, T is the temperature from Step 1 and R is a proportionality constant equal to 0.0821 L atm / K mol.
Hope this helps at all
Answer:
All elements in Group 18 are called noble gases and are nonreactive which means they don’t readily react with other elements.
Explanation:
Molarity or M =. Moles of solute/ liters of solvent. So. 5.0/2.0=2.5. 2.5 m is your answer
Answer:
Explanation:Metalloids may act either like metals or nonmetals in chemical reactions. Most metalloids have some physical properties of metals and some physical properties of nonmetals. They fall between metals and nonmetals in their ability to conduct heat and electricity. They are shiny like metals but brittle like nonmetals.
