Answer:
Moles of Hydrogen produced is 5 moles
Explanation:
The balanced Chemical equation for reaction between zinc and sulfuric acid is :
This equation tells that ; when 1 mole of Zn react with 1 mole of sulfuric acid, it produces 1 mole of zinc sulfate and 1 mole of hydrogen.
Since sulfuric acid is in excess so Zinc is the limiting reagent
(Limiting reagent : Substance which get consumed when the reaction completes, limiting reagent helps in predicting the amount of products formed)
Limiting reagent (Zn) will decide the amount of Hydrogen produced
So,
Hence moles of Hydrogen produced is 5 moles
2. 5 acids: coffee, lemonade, soda pop, orange juice, vinegar
5bases: ammonia, baking soda, cough medicine, liquid soaps
3. Acids are very common in some of the foods we eat.
Bases have properties that mostly contrast with those acids
4. Acid+Base=H2O+Salt
HCI+NaOH=H2O+NaCI
Explanation:
2. (all those acids are strong (in pH meaning those are weak and don't affect you) (most the bases are very strong like ammonia)
4. Salt means any ionic compound formed from an acid/base reaction
Hope this helped
Well, if u had a spilled liquid in there (we'll simply go with water) and you had the freezer at a cold temperature it would change (like,icycles on trees when it's snowing)
Answer:
4
Explanation:
The zeros before a non zero digit do not count as significant figures so there are 4 sig figs in the number
