lana [24]

Answer:

(a) OPTION E=4

b) option E C sp² + C p

Explanation:

DEGREE OF UNSATURATION = C -H/2 -X/2 +N/2 +1

X IS HALOGENS

5-5/2+1/2+1= 4

b) Ethene comprises of two sp2-hybridized carbon atoms (bound to each other by sigma and two atoms each with hydrogen). The remaining unhybridized carbon p orbitals form a pi bond, giving ethene reactivity

A sample of water (88 grams) had a temperature change of 6.0 ℃. What was the heat change of this sample? (q = m c ΔT, c = 4.18 J

jeka94

Answer:

$Q=2209J$

Explanation:

Hello!

In this case, since the heat involved during a heating process is computed in terms of mass, specific heat and temperature change as shown below:

$Q=mC\Delta T$

Thus, since the heated mass of water was 88 g, the specific heat of water is 4.184 J/g°C and the temperature change is 6.0 °C, we can compute the heat as shown below:

$Q=88g*4.184\frac{J}{g\°C}*6.0\°C \\\\Q=2209J$

Best regards!
