Answer:
Primary structure is the correct answer.
Explanation:
- The primary structure is the simple level of protein structure.
- Primary structure is a basic amino acids sequences in a protein.
- In the primary structure, amino acids are attached together by a covalent bond.
- Primary structure is when the amino acids are joined together with peptide bonds to produce polypeptide chains
- Changes in pH are least likely to change the amino acid sequence or disrupt peptide bonds.
Explanation:
Answer:
1. Carbon dioxide, increase of green house gas
2. Stop deforestation, cut down amount of cars on the road (encourage public to take public transport), reduce the amount of time u on the air-conditioning
Answer:
0.74 grams of methane
Explanation:
The balanced equation of the combustion reaction of methane with oxygen is:
it is clear that 1 mol of CH₄ reacts with 2 mol of O₂.
firstly, we need to calculate the number of moles of both
for CH₄:
number of moles = mass / molar mass = (3.00 g) / (16.00 g/mol) = 0.1875 mol.
for O₂:
number of moles = mass / molar mass = (9.00 g) / (32.00 g/mol) = 0.2812 mol.
- it is clear that O₂ is the limiting reactant and methane will leftover.
using cross multiplication
1 mol of CH₄ needs → 2 mol of O₂
??? mol of CH₄ needs → 0.2812 mol of O₂
∴ the number of mol of CH₄ needed = (0.2812 * 1) / 2 = 0.1406 mol
so 0.14 mol will react and the remaining CH₄
mol of CH₄ left over = 0.1875 -0.1406 = 0.0469 mol
now we convert moles into grams
mass of CH₄ left over = no. of mol of CH₄ left over * molar mass
= 0.0469 mol * 16 g/mol = 0.7504 g
So, the right choice is 0.74 grams of methane
Answer:
SO3 2- which is sulfite
i have to put this because it doesnt let me send the answer like that :)
