Dioxane, C4H8O2, has an enthalpy of fusion of 145.8 J g–1 and its melting point temperature is 11.0 °C. How much heat is require
kumpel [21]

Answer:

20703.6J

Explanation:

Quantity of heat (Q) = mass of dioxane × enthalpy of fusion

Mass of dioxane = 142g

Enthalpy of fusion of dioxane = 145.8J/g

Q = 142g × 145.8J/g = 20703.6J

Taking logarithms and antilogarithms is necessary to solve many chemistry problems. For practice,
shepuryov [24]

The values of N, log N and ln N are all worked out below.

We have the number N as 8.99

hence;

1) lnN = ln(8.99) = 2.196

log N = log (8.99) = 0.954

2) If we have ln N as 3.949

N = e^3.949 = 51.88

So;

log N = log (51.88) = 1.715

3) log N = 0.134

N = Antilog (0.134 ) = 1.36

ln N = ln (1.36) = 0.307

Chlorine (cl) has an atomic number of 17. it often forms an ion by gaining 1 electron. what would its charge be?
Aliun [14]

Answer:

= -1

Explanation:

  • Chlorine belongs to the halogen group in the periodic table. It has an atomic number of 17, which indicates the number of protons and electrons in a neutral atom of chlorine is 17.
  • Therefore; with an atomic number of 17, its electronic configuration will be 2:8:7.
  • Thus; to attain a stable configuration chlorine requires to gain one electron, by so doing it becomes a negatively charged ion with a charge of -1.
