CO is a fuel while N is not a fuel. There was a similar question that said Oxygen instead of Nitrogen. The fuels that I know are CO CH4 H2 all hydrocarbons and some others but N2 and O2 are defenatliy not a fuelWhich gas cannot be used as a fuel?
A carbon monoxide
B hydrogen
C methane
D nitrogen
help please! well i know that hydrogen and methane can be used as a fuel, but i don't get why the answer is D not A! helpppp
carbon monoxide is a fuelA is a fuel while nitrogen is not
Yes it is it can be used but it has the same problem as H2 in transport as it is a gas. I couldn't believe it when my teacher told me too.carbon monoxide is a fuel
oh thank you so muchYes it is it can be used but it has the same problem as H2 in transport as it is a gas. I couldn't believe it when my teacher told me too.
Nope it should be B hydrated CoCl2 is pink and it is an exothermic reaction as forming of bonds will give energy. Steam will trick you as it will increase the temperature so the opposite reaction will have to be decrease but it doesn't depend on steam it depends if the bonds were broken or formedShouldn't the answer be A?

Assalam-o-alaikum wr wb..Biology Questions:
November 2006
Number 26 I understand 1 or 2 parents required but how more male than female ???
this is bcoz the flower shown in the picture isn't the full flower...it's the half flower and therefore in a full flower the stamens will be more than 4..Biology Questions:November 2008
Number 3 The petals are separated from petals , but there is 4 stamens only ????

How are the anthers are lost ?Assalam-o-alaikum wr wb..
more males cuz most of them gametes (anthers) are lost!
Oh yeah . I understood that .this is bcoz the flower shown in the picture isn't the full flower...it's the half flower and therefore in a full flower the stamens will be more than 4..
Hope that helps!
You mean more pollen are landing on the stigma right so they will be more than the ovules inside. I got it !! Thanks A lot .How are the anthers are lost ?
when they are carried by wind, in wind pollinated flowers or by insects in insect pollinated flowers!How are the anthers are lost ?
You mean pollen not anther right?when they are carried by wind, in wind pollinated flowers or by insects in insect pollinated flowers!
bcoz not all of them reach the stigma....
nope...i mean in sexual reproduction...flowers are either insect pollinated or wind pollinated...in insect pollinated flowers not all of the anthers/pollen grains reach the sticky stigma...some may be left over on the bodies of insects...which means that there are more pollen grains as some of them are lost!You mean more pollen are landing on the stigma right so they will be more than the ovules inside. I got it !! Thanks A lot .
pollen grains are inside the anthers only..so sorta yeah!You mean pollen not anther right?
mmm.... If this is your suggestion then more female , which I thought of . But that is wrong because more pollen will Land on stigma than the number of female gametes inside the ovary of the flowering plant , I think that's reasonable? I dunno, everyone has his own thinking .when they are carried by wind, in wind pollinated flowers or by insects in insect pollinated flowers!
