Answer:
1,033.56 grams of carbon dioxide was emitted into the atmosphere.
Explanation:
Energy absorbed by pork,E = 
(assuming)
Total energy produced by barbecue = Q
Percentage of energy absorbed by pork = 10%
Since, it is a energy produced in order to indicate the direction of heat produced we will use negative sign.
Q = 
Moles of propane burnt to produce Q energy =n
According to reaction , 1 mol of propane gives 3 moles of carbon dioxide. then 7.83 moles of will give:
carbon dioxide gas.
Mass of 23.49 moles of carbon dioxide gas:
23.49 mol × 44 g/mol =1,033.56 g
1,033.56 grams of carbon dioxide was emitted into the atmosphere.
The are isotopes because the atomic number (meaning a same number of protons) is the same but the atomic masses are different. this means they have a different number of neutrons which is what isotopes are.
answer is E- all of these
Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Explanation:
Answer:the answer is A I think, tell me if I’m wrong
Explanation:
Answer:
Boil the water until it evaporates
Explanation:
If the water evaporates the sugar will no longer bond to it and then percipitate at the bottom of the beaker.
