Carbon is the answer. all hydrocarbures have to contain carbon.
Answer: 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of calcium chloride
Explanation:
The balanced chemical equation is:
According to stoichiometry :
2 moles of 
require 3 moles of 
Thus both are limiting reagent as both will limit the formation of product.
As 2 moles of reacts with 3 moles of give = 6 moles of 
Thus 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of calcium chloride
Aluminum is light and is quite unreactive it is malleable and strong too.
Answer:
Changing the pendulum design after the first trial was an example of <u>evaluating the model</u> to solve the problem presented by the teacher.
Explanation:
A model constitutes an abstract representation of a certain aspect of reality, and has a structure that is formed by the elements that characterize the aspect of the modeled reality and by the relationships between these elements.
This achieved result provides a better understanding of the problem being studied, offering aspects that can be changed or improved to solve the problem posed, obtaining more information about the reality of the phenomenon that is being represented.
Answer:
D. a very fast run
Explanation:
Fermentation :
The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced, however carbon dioxide is released in this step.
Anaerobic respiration in plants:
Anaerobic respiration in plants produced ethanol which if accumulate then cause the harmful effect in plants. It is also occur in some microorganisms such as yeast.
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
Anaerobic respiration in animals:
Anaerobic respiration in animals pyruvate converted into lactic acid and it is not as harmful as ethanol in plant if accumulate. It is produced during exercise because oxygen is not supplied to muscles. It can produce the cramps which can be cured with massage.
C₆H₁₂O₆ → 2C₃H₆O₃
