Answer:
C) It is the reactant that is left over after the reaction stops.
Explanation:
The excess reactant is the reactant that is left over after the reaction stops. The extent of the reaction is not determined by this reactant.
A limiting reactant is a reactant that is in short supply within a given reaction.
Such reactants determines the extent of chemical reaction.
- Limiting reactants are used up in a chemical reaction.
- The excess reactants remains unchanged after the reaction.
Answer:
People wanted to settle there because it had good living conditions. There was rich soil, and lots of water sources.
I hope this helps!
Answer:
Ahahaha no but thank you. Have a nice day luv! :-))
Answer:
B. 0.174
Explanation:
A buffer is formed by a weak acid (CH₃COOH) and its conjugate base (CH₃COO⁻, coming from sodium acetate). We can calculate the pH of this buffer using the Henderson-Hasselbalch equation.
pH = pKa + log [CH₃COO⁻]/[CH₃COOH]
pH - pKa = log [CH₃COO⁻]/[CH₃COOH]
3.98 - (-log 1.80 × 10⁻⁵) = log [CH₃COO⁻]/[CH₃COOH]
-0.760 = log [CH₃COO⁻]/[CH₃COOH]
[CH₃COO⁻]/[CH₃COOH] = anti log (-0.760)
[CH₃COO⁻]/[CH₃COOH] = 0.174
A single monkey is not an ecosystem
As ecosystem comprises of all the living and non living parts a community under study.
So if have define an ecosystem of which monkey is a part then we have to include the living organism like tress and monkey and the non living parts like rock and wind which affects the living organism.
