Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
Answer:
9842kJ of energy are released
Explanation:
Based on the reaction:
2 C₄H₁₀ (g) + 13 O₂ (g) → 8 CO₂(g) + 10 H₂O (g) + 5720 kJ
<em>When 2 moles of C₄H₁₀ react with 13 moles of O₂ there are released 5720 kJ of energy</em>
As molar mass of C₄H₁₀ is 58.12g/mol, moles in 200.0g of the hydrocarbon are:
200.0g C₄H₁₀ ₓ (1mol / 58.12g) =<em> 3.441 moles of C₄H₁₀</em>
<em> </em>
As 2 moles of C₄H₁₀ release 5720kJ of energy, 3.441 moles of C₄H₁₀ release:
3.441 moles C₄H₁₀ ₓ (5720kJ / 2 moles C₄H₁₀) = <em>9842kJ of energy are released</em>
The ionic charge of oxygen is -2.
Hope this helps! ;)
Answer: Glaciers can erode around rock. They shift over time so it causes the rock (or glacier) to erode. If it erodes enough it creates a valley. The glacier causes it to go deeper and deeper! That is how valleys are made!
