A food web is a graphic representation of all possible energy pathways through an ecosystem.
Answer:
The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. ... When displacement vectors are added, the result is a resultant displacement.
Answer:
The answer to your question is: 303g of CO2
Explanation:
Data
mass CO2 = ?
mass C4H10 = 100 g
MW C4H10 = 58.12 g
MW CO2 = 44.01 g
Solve this problem using rules of three
Reaction
2 C4H10 (g) + 13 O2 (g) → 8 CO2 (g) + 10 H20 (l)
2(58.12) ------------------ 8(44.01)
100g ------------------- x
mass of CO2 produced = x = (100)(8)(44.01) / (2)(58.12)
x = 35208 / 116.24
x = 302.9 g ≈ 303 g of CO2
The correct option is A.
The band theory of metal refers to the process by which metals conduct electricity, using the electrons in their outermost shells. Metal bands are formed, when the atomic orbitals of those metals that have similar energy level combine together to form molecular orbitals. The bands formed in the metals assist the electrons in the metals to move about, thus, the metals are capable of conducting electricity.
I believe it's D! Hope you can help with my question!
