Answer:
The amount of heat required to raise the temperature of the sample from 298 to 385 Kelvin, is 16.6 kJ
Explanation:
<u>Step 1: </u>Given data
A 79.0 g sample of ethanol raises from 298 K to 385 K
The specific heat of ethanol is 2.42J/g°C
<u>Step 2:</u> Calculate the heat transfer
Q = m*Cp*ΔT
with m = the mass of the ethanol sample (in grams)
⇒ mass = 79 grams
with Cp = the specific heat capacity of ethanol (in J/g°C)
⇒ Cp = 2.42 J/g°C
with ΔT = the change of temperature (T2-T1)
⇒ ΔT = 385 K - 298K = 112 °C - 25 °C = 87
Q = 79 grams * 2.42 J/g°C * 87 = 16632.66 j = 16.6 kJ
The amount of heat required to raise the temperature of the sample from 298 to 385 Kelvin, is 16.6 kJ
xplanation:
A line shows a bonding pair of electrons (which are usually 2 for every line) – the atoms involved in the bond share two electrons per bond to form a covalent bond. The two dots show a pair of lone electrons NOT involved in bonding.
The Carbon and Sulfur will require to have their valence orbital shell involved in the bonding to have 8 electrons. The Hydrogens need 2 to achieve stable electron configuration. This way the atoms achieve stability in the molecule
Well depends on what type of fish the parent is but i guess you can say:
what they eat
teeth
instincts
color
venom
blending in,etc
The correct answer is:
Metals
They are all alkali and transition metals
Explanation:
The periodic table includes elements clustered into groups with comparable properties. Alkali metals are reactive, soft metals with low densities. Transition metals are unreactive metals that have many have common uses. Halogens are reactive non-metals that form glowing vapors.
