Answer:
D.) 2.5 moles
Explanation:
To find the moles of H₂, you need to multiply the given value by the mole-to-mole ratio. This ratio consists of the coefficients in front of the relevant molecules. It is important to arrange the ratio in a way that allows for the cancellation of units.
1 Mg + 2 HCl -----> MgCl₂ + 1 H₂
^ ^
2.5 moles Mg 1 moles H₂
----------------------- x --------------------- = 2.5 moles H₂
1 mole Mg
Answer:
neutralization reaction
Explanation: Because Neutralization Reactions. ... from a neutralization reaction
True
Carbon monoxide is a primary pollutant which no odor results from incomplete combustion of fuel. The man sources are gasoline and burning of biomass.
Depending on the source of emission, pollutants can be classified into two groups that is primary and secondary pollutants.
A primary pollutant is emitted in the atmosphere directly from a source. It can be either natural sch as volcanic eruptions, sandstorms or man-made that is due to industrial and vehicle emissions. Examples of primary pollutants are nitrogen oxides, carbon monoxide and particulate matter.
Secondary pollutant is due to interactions between primary and secondary pollutants. These can be chemical or physical interactions. Examples are photo-chemical oxidants and secondary particulate matter.
Therefore, carbon monoxide CO is a primary pollutant.
Answer:
P1V1= P2V2
Explanation:
Inverse relationship
V2 = V1 X P1/P2
V2= 14.3 L x 45.0 mm Hg/63.0 mmHg= 8.99
