15ft is the same as how many yards?

Exothermic,  physical change after it is already baked

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it

58.6 you welcome glad to

for left side: 3 c, 8 h, 2 o. for right side, 1 c, 3 o, 2 hwe want to balance oxygen last because it is the only one that is isolated. we can fine tune it at the end.put a coefficient on right side to balance the number of carbons.now make the number of hydrogens eventhere are 8 h on the left and 2 h on the right. put a coefficient on the right side like so: now we have 10 oxygens on the right and 2 on the left. to get the left side to have 10 oxygens, put a coefficient of 5 (5 * 2 = 10)the coefficient in front of  in the balanced equation is 3.
