Look at this equation: 2 H2 + O2 --> 2 H2O. Why isn't there any coefficient in front of oxygen? HELP!! A. A one is assumed when no coefficient is present.

B. There is an unlimited amount of oxygen

C. The 2 after the oxygen is all that is needed

D. All of these

A:one is assumed when no coefficient is present

Step-by-step explanation:

seems right to me if in wrong im sorry :|

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
