Answer: 0.39mol of the steam are in the cooker.
Explanation:Please see attachment for explanation
<span>We know the relation between heat and temperature follows the formula:
Q = Ce * m * (Tf-Ti) , where Q is heat transfer, Ce is specific heat, m is mass, Tf is final temperature and Ti is initial temperature.
Note that heat value is given in kj so we need to change to joules, then as heat is absorbed the final temperature will increase.
4,689 = 0.385 * 34.2 * (Tf-24)
Tf = 4,689 / (0.385 * 34.2) + 24 =380.12ÂşC</span>
Since there are given data of two reagents, we need to obtain which of reagents are surplus.
0.3618 mol C4H4 - x mol O2
1 mol C4H4 - 5 mol O2
that means that there are too much O2 gas (by 0.009 mol)
so we continue counting using C4H4 data
0.3618 mol C4H4 - x mol H2O
1 mol C4H4 - 2 mol H2O
Mw(H2O)=2×1+16=18 g/mol
n=m/Mw
m=n×Mw
answer:13.0248 grams of H2O
A sodium chloride is like most of the ionic compounds
existing here on earth in which they are composed of having a high melting
point and by this, if found in underground rock deposits, they are usually in a
form of solid.
Answer:
people are mostly exposed to chemicals through their nose, mouth, eyes, and ears
Explanation:
they are the easiest way for anything, bad or good, to enter the body because people touch their face alot.
This might not answer what you were looking for but the other answer covered it pretty well so I thought I'd give you another angle to the question!
Hope this helps!!
