Answer:
C. CO2 exists in relatively high concentrations.
Explanation:
From the available options:
A. CO2 molecules are highly symmetrical.
B. CO2 has a low molar mass.
C. CO2 exists in relatively high concentrations.
D. CO2 is formed in the combustion of fossil fuels.
<em>The focus on CO2 as far as global warming is concerned is not because It has a high global warming potential but because of its relatively high concentration in the atmosphere as a result of both natural and anthropological activities.</em>
The correct option is C.
This would probably be based on the number and type of chemical bonds the substance has.
Answer:
Hypothesis
Explanation:
A hypothesis is often described as a scientific guess.
Scientific method is a series of systematic approach developed to carry out scientific investigations.
These methods are:
Observation ----- Hypothesis --------- Theory ------------ Law
A hypothesis is a scientific explanation to an observation. It provides a platform for carrying out experiments to test ideas and to see how repeatable an observation can be.
Explanation:
potassium oxide is K2O
calcium oxide is CaO
calcium oxide is used to make glass
potassium oxide is used in fertilizer
ok so for this you need to know how to convert measurements.
12.5km needs to be in cm. So you need to know what unit conversion is going to get me cm and sometimes its more then 1 step.
So one way is we could use these conversions km to m and then m to cm
So turn 12.5km into a fraction over 1 (12.5/1km)
and times it by 1000m over 1km you should get 12500m.
Next take 12500m over 1 and multiply it by 100cm over 1m as a fraction so then your anwser should be 1,250,000cm
