Hello!
By law of Dalton’s partial pressure the sum of the partial pressures is the total of all the pressures. So if the total is 740mm Hg then 740=400+200+x
so solving for x the unknown pressure we get 740-600=140mm Hg.
Hope this helps! Any questions please just ask! Thank you so much!
Answer is: A) Sr (strontium).
The reactivity series<span> is a series of metals from highest to lowest reactivity.</span><span> Metal higher in the reactivity series will displace another.
</span>Strontium is only higher in this group from magnesium. Strontium is stronger reducing agent than magnesium, gives electrons easier.
Answer:
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
