Answer is: empirical formula for compound is C₂H₆O.
m(CO₂) = 1,6003 g.
n(CO₂) = m(CO₂) ÷ M(CO₂).
n(CO₂) = 1,6003 g ÷ 44 g/mol.
n(CO₂) = 0,0364 mol.
n(CO₂) = n(C).
m(C) = 0,0364 mol · 12 g/mol = 0,4368 g.
m(H₂O) = 0,9827 g.
n(H₂O) = 0,9827 g ÷ 18 g/mol.
n(H₂O) = 0,0546 mol.
n(H) = 2 · n(H₂O) = 0,1092 mol.
m(H) = 0,1092 mol · 1 g/mol = 0,1092 g.
m(O) = 0,8376 g - 0,4368 g - 0,1092 g = 0,2916 g.
n(O) = 0,2916 g ÷ 16 g/mol = 0,0182 mol.
n(C) : n(H) : n(O) = 0,0364 mol : 0,1092 mol : 0,0182 mol.
n(C) : n(H) : n(O) = 2 : 6 : 1.
atom x is sodium and then the atom y is chlorine
They use natural resources like sunlight water they need soil water and sunlight to grow the stem should be pliable and firm and will have a green cast on the inside
Answer:
#P: 15
#N: 16
Mass Number: 30.973762u (You can round it if you want)
Isotope symbol: P
Explanation:
I hope this helps :)
Use this equation:
q = mc∆T
q is the heat energy your trying to find out
m is the mass of water (150g)
c is the specific heat capacity of water (4.18)
∆T is the temperature change (96.3-38.8)
so just multiply m c and ∆T to find q in joules
