Is HPO4 2 acid or base when mixed with NO2?
HPO4-2 is an acid and a base. however when mixed with NO2- (Base) then HPO4-2 must be an acid.
Which two metals explode in water?
Group 2 metals (alkaline earth metals), calcium and barium would be examples
What metals react violently with acid?
All alkali metals (group 1) and most earth-alkali metals (group 2)
What are the trends in reactivity with HCl in alkaline earth metals?
The Alkali Earth metals are found in group 1 and 2 of the periodic table. When reacted with hydrochloric acid, the vigour of the reactions increases going down the groups. So Lithium will react gently with hydrochloric acid whilst Caesium will react explosively. The same applies for the group 2 metals. Generally speaking, Alkali metals will react with hydrochloric acid: X + HCl -----------> XCl + H2 Where X is the alkali metal and will react to form a chloride
Which 2 metals can displace hydrogen from dilute nitric acid?
magnesium and manganese Mg(s) + 2 HNO3(aq) → Mg(NO3)2(aq) + H2(g)

When 2 metals are mixed together does this make a compound?
No: Two metals mixed together form a special kind of homogeneous mixture called an "alloy".
What metals react violently with acid?
All alkali metals (group 1) and most earth-alkali metals (group 2)
What blows up when mixed?
Menthos mints inserted into a 2-liter soda pop (plastic) bottle will explode after the acid in the soda breaks down the mint: some people make rockets out of them! GET AN ADULT TO SUPERVISE FOR YOUR OWN PROTECTION!
Are the 2 most reactive metals with hydrochloric acid?
Hydrogen and chlorine.
Can a bacterium that ferments using the 2 3-butanediol pathway use the mixed acid route?
Yes, but the PH will not fall as low as with the mixed acid route. The PH is an indicator of the route the bacterium used to ferment.
How much pure acid should be mixed with 2 gallons of a 50 percent acid solution in order to get an 80 percent acid solution?
pH less than 7
Do metals reacts with acid to form a salt and hydrogen?
Yes. Example: 2 Na + 2 HCl ---> 2 NaCl + H2 Sodium (Na) is a metal.HCl is hydrochloric acid. Sodium Chloride (NaCl) is a salt.

Which metal and acid would react together to give off oxygen?
Most metals react with acids to give off hydrogen. Only very nonreactive metals, like gold and platinum do not react with metals. An example would be: Calcium + Hydrochloric Acid = Calcium chloride + Hydrogen gas (Ca +2 HCl = CaCl2 + H2)
Which 2 metals can displace hydrogen from dilute nitric acid?
magnesium and manganese Mg(s) + 2 HNO3(aq) → Mg(NO3)2(aq) + H2(g)
