<u>Answer:</u>

The percentage of honey in one granola bar is 26.02 percent.  

<u>Explanation:</u>

The weight of 1 granola bar is 42.9 grams. The grams of honey that is present in one granola bar is equal to 26.02 percent of 42.9 = 11.16 g

Now the amount of honey in the factory is given as 189.5g the weight of total granola bars would be

                                     = 42.9/11.16 x 189.5= 728.25

So no. of granula bars =728.25/42.9 =16.9 that can be Approximated to nearly 17

Now if one box has 6 bars then 17 bars will have to fit inside three boxes

Acetylene (c2h2) undergoes combustion in excess oxygen to generate gaseous carbon dioxide and water. given δh°f[co2(g)] = –393.5
Brums [2.3K]
Answer is: 13181,7 kJ of energy <span>is released when 10.5 moles of acetylene is burned.
</span>Balanced chemical reaction: C₂H₂ + 5/2O₂ → 2CO₂ + H₂O.
<span>ΔHrxn = sum of ΔHf (products of reaction) - sum of ΔHf (reactants).</span><span>
Or ΔHrxn = ∑ΔHf (products of reaction) - ∑ΔHf (reactants).
ΔHrxn - enthalpy change of chemical reaction.
<span>ΔHf - enthalpy of formation of reactants or products.
</span></span>ΔHrxn = (2·(-393,5) + (-241,8)) - 226,6 · kJ/mol.
ΔHrxn = -1255,4 kJ/mol.
Make proportion: 1 mol (C₂H₂) : -1255,4 kJ = 10,5 mol(C₂H₂) : Q.
Q = 13181,7 kJ.

A bacteria culture begins with 15 bacteria which double in amount at the end of every hour. Solve for the number of bacteria tha
pshichka [43]
The number of bacteria is given by:
N(t) = N(o) x 2ⁿ
Where N(t) is the number after n hours have passed and N(o) is the original number which is 15.
The number grown in the 12th hour is the difference in the number after the 11th and the 12th hour. Thus:
15 x 2¹² - 15 x 2¹¹
= 30,720 bacteria

Why can some metals be extracted from compounds by heating with carbon and why can some not
pentagon [3]

Answer:

Some metals can be extracted from compounds by heating with carbon atom because they are less reactive than carbon and some metals cannot be extracted because they are more reactive than carbon atom.

Explanation: If the metal is less reactive than carbon atom so the carbon atoms make bond with oxide or other atom present with metal and the metal is free from that oxide or that element. But if the reactivity of metal is higher than carbon is unable to remove the oxide or element.
