The density of water is about 1kg/m³, therefore is the substance has a density of less than 1kg/m³ then it will most likely float however if it is more than 1kg/m³ then it will most likely sink.
Answer: C you have a small amount of substance
Photosynthesis takes place in all ecosystems. Without it we would not be able to survive. Photosynthesis starts with plants. Plants are autotrophs which means they make their own food. During photosynthesis, plants take in sunlight, carbon dioxide (CO^2), and water during photosynthesis. They give off glucose and oxygen. Plants have chlorophyll in them which gives them their green color. Heterotrophs eat other living things to get energy. (If you want to go more into depth you can say this: Heterotrophs take in the glucose and oxygen. This is called cellular respiration. The products of cellular respiration are water, ATP (energy), and CO^2 which than leads you back to photosynthesis) Hope this helped! :)
The structure of isocynide is
N=C
What is the importance of VSEPR theory?
Valence bond theory describes the electronic structure of molecule .The theory says that electrons fills the atomic orbitals of an atom within a molecule .
In the structure of isocynide there are triple bonds between Nitrogen and carbon . The bond length is 115.8pm and the bond angle is 180°. There is two pi and one sigma bond .

Answer:
CH4+2O2→CO2+2H2O
Moles of oxygen=3232=1
Moles of carbon dioxide=4422=0.5
Moles of water=1818=1
1 mole of methane reacts with 2 moles of oxygen to give 1 mole of CO2 and 2 moles of water so 0.5 mole of methane will be required which is equal to 0.5×16=8g.
Explanation:
8g
