heat required: 169452 Joules

  • use the formula, Q = mcΔT

<u />

<u>Q is heat required, m is mass in kg, c is s.h.c , ΔT is change in temperature</u>

  • Here, the units of s.p.c and mass matches, in grams
  • if did not match, we have to convert into specific unit.

↪ Q = 1500 * 4.184 * (52-25)

↪ Q = 169452 J

  • Mass=1500g=m
  • ∆T=52-25=27°C
  • Specific heat capacity=c=4.184J/g°C

Apply thermodynamics

\\ \rm\rightarrowtail Q=mc\delta T

  • Q is heat

\\ \rm\rightarrowtail Q=1500(4.184)(27)

\\ \rm\rightarrowtail Q=169452J

Consider a series of molecules in which the C atom is bonded to atoms of second-period elements: C-O, C-F, C-N, C-C, and C-B. Pl
Sati [7]

Answer:

  1. C-B
  2. C-C
  3. C-N
  4. C-O
  5. C-F

Explanation:

As we move along to the <u>right in the same period, the electronegativity</u> and <u>the effective nuclear charge values are higher.</u>

The tendency is that <em>the higher these values are, the shorter the bonds will be</em>.

With that information in mind, and looking at the periodic table, the order would be:

  1. C-B
  2. C-C
  3. C-N
  4. C-O
  5. C-F

Where the C-F bond is the shortest among them.

The following equation shows the correct molecules formed in the reaction, but the products are incorrect. CH4 +202=H20+ CO2 How
Hunter-Best [27]
For the equation to balance out, you would need 2 H2O on the product. That will give a total of 1 Carbon, 4 Hydrogens and 4 Oxygens on each side.

Give all possible, accurate, correct IUPAC names for the following compounds:
Viefleur [7K]

Answer:

A. 4-ethyl-hex-3,5-dien-2-ol.

B. 2-chloro-3-methyl-5-<em>tert</em>-butylphenol.

Explanation:

Hello there!

In this case, according to the given problems, it is possible to apply the IUPAC rules to obtain the following names:

A. 4-ethyl-hex-3,5-dien-2-ol because we have an ethyl radical at the fourth carbon and the beginning of the parent chain is on the Me (CH3) because it is closest to first OH.

B. 2-chloro-3-methyl-5-<em>tert</em>-butylphenol: because we start at the alcohol and have a chlorine atom on the second carbon, a methyl radical on the third carbon, a <em>tert</em>-butyl on the fifth carbon and the parent chain is benzene which is phenol as an alcohol.

Regards!
