Answer:
CH4+2O2→CO2+2H2O
Explanation:
Start with the least common atoms and leave things like H and O to the end.
You need to have the same number of methane reactants as carbon dioxide products because there is one carbon in each. I’ll set them both to 1 for now. O see two things with oxygen on the product side so we will have to juggle numbers a bit to figure out those. There is only H in the water so we’ll go there next. One CH4 gives 2 water molecules so we have that done now. At last we can tackle the O atoms. In two waters there are 2 and in the CO2 there are two more so a total of 4 O atoms in the products so we need two O2 molecules in the reactant side.
Hope this is useful.

The student mixed up 500ml of salt solution. He weight it and found it mass to be 585g. will his shake up toy work the way that he want it to work?why or why not?
Remember, 1 mL = 1cm
Show your math
Answer:
...
Explanation:
find density of salt solution 585g/500cc = 1.17g/cc
leaves density = 1.25g/cc, stars density = 1.12g/cc
Stars float, leaves sink. since everything is in g/cc, you do not have to worry about the info 1ml=1cc.
density = mass / volume.
density of salt solution = 585g(mass)/500cc(volume)

How do the light rays emitted by a candle travel?
Answer:
Explanation:
The light rays coming from the unlit candle and the reflected light rays of the lit candle are superposed on top of one another. ... For very transparent substances like glass, only about 5 percent of the light that hits it is reflected. The remaining 95 percent is transmitted—it passes right on through.

A: B: C:
Answer:
A: petal
B:stigma
c: stamen
Explanation:
A flower is considered as a complete one if it has petals, stamen, carpel and sepals. Sometimes pistil is present. Here in the structure part A is Petal, B is Stigma and C is stamen.
What are parts of a flower?The calyx, corolla, androecium, and gynoecium are found to be the four whorls of a modified leaves which constitute the flower. One of the flower parts in each of the whorl contains sepals, petals, stamens and pistils.
Here A is petal. This part is the bright coloured region which attracts bees and birds. This part help us to differentiate one flower from another. Some petals are dark coloured whereas some other are pale coloured.
Here B is stigma. The stigma is the sticky part of a flower. It is the specially adapted portion of the pistil modified for the reception of pollen. It has a feathery, branched elongated structure.
Here C is stamen - The male reproductive part of a flower is called the stamen. The stamen has long slender stalk called the filament with a two -lobed anther at the tip.
Thus the given parts are petal, stigma and stamen.
