Answer:
The statement that describes the advantage of a nonrenewable energy source is that ' they are currently found in abundance' Option D.
Explanation:
Nonrenewable energy sources are sources of energy which will not be replenished after their use, their production usually takes millions of years to be accomplished, Like crude oil, the synthesis under the ground was believed to take Millenium from the various geothermic reactions that occur on the buried biomass millions of years ago.
However, since these energy sources are liable to be exhausted quickly due to their unreplenish nature, nature provides them in abundance. They are currently found in large quantity. Take for example, the coal deposit and crude oil wells which had been mined for many years before now. The continuous usage of these nonrenewable sources nevertheless makes them to be susceptible to exhaustion in some years to come.
Answer:
Silver
Explanation:
Given parameters:
Mass = 116g
Energy = 511J
Initial temperature = 21.6°C
Final temperature = 40.5°C
Unknown:
Specific heat capacity and the type of metal = ?
Solution:
To solve this problem, we need to find the specific heat capacity of the metal given,
H = m x c x Ф
H is the energy
m is the mass
c is the specific heat capacity
Ф is the change in temperature
511 = 116 x c x (40.5 - 21.6)
511 = 2192.4c
c = 0.233J/g°C
The specific heat capacity of silver is similar to this.
Answer: -
The chemical formula of Antimony(III) sulfide = Sb₂S₃
Mass of Sb produced = 175.6 g
Molar mass of Sb = 121.76 g /mol
Number of moles of Sb = 175.6g / (121.76 g/mol)
= 1.44 mol
The balanced chemical equation for this reaction is
Sb₂S₃ + 3 Fe → 2 Sb + 3 FeS
From the chemical equation we see
2 mol of Sb is produced from 1 mol of Sb₂S₃
1.44 mol of Sb is produced from 
= 0.72 mol of Sb₂S₃
Molar mass of Sb₂S₃ = 2 x 121.76 + 32.06 x 3
= 339.7 g / mol
Mass of Sb₂S₃ = 0.72 mol x 339.7 g/ mol
= 244.58 g
= 244.6 g rounded off to 4 significant figures.
Answer:
i dont even know tbh jk i wont waste ur time unless nvm ok so the answer is The correct answer would be C.10. Krebs cycle is a part of cellular respiration that takes place in the mitochondria. Five energy conversions take place in one complete cycle of the Krebs cycle. These conversions lead to the formation of three molecules of NADH, one molecule of FADH₂ and one molecule of ATP.
