So what you need to do is to have all your answers in the same unit as the one in the question which is K then look for the one that is greater than that in the question because only then will it absorb heat from the water.

temp. of rod:  325K
(1)  65 K
(2) 45 K
(3) 65° C  =  (65 + 273) K = 338 K
(4) 45° C  =  (45 + 273) K = 318 K

⇒ option 3 is the answer

If 5.100 g of c6h6 is burned and the heat produced from the burning is added to 5691 g of water at 21 °c, what is the final temp
emmasim [6.3K]
  <span>C6H12 = 6x12 + 6x1 = 78. 
The equation indicates that 2x78 = 156g benzene will produce 6542kJ. 
Using proportions you can then calculate that 
x/6542kJ = 7.9g / 156g 
x = 331.3kJ = 331300J. 

heat = mass x ΔT x 4.18J/g° 
ΔT = 331300J / (5691g x 4.18J/g°) = 13.9° 

final temp = 21 + 14° = 35°C</span>

Which instrument is most often used to measure acid volume before a titration begins?
Darya [45]

<span>Good Morning!
 
To measure the volume of an acid we use in the laboratory an instrument called burette (a). This instrument is used to calculate the volumes of chemical solutions. At first glance, these tools may be confused with syringes, but have different functions.

PLS HELP what is 2x10^3 in long form
saul85 [17]

Answer:

2x1000 = 2000

Explanation:

10^3 = 10×10×10 = 1000

exponent , the ^3 means multiply the number by itself 3 times, if it was ^4, it would be 4 times and so forth.

another trick for 10s is just put the 1 and the exponents number of 0's after the 1. so in this case, put three 0's: 1,000

Trans-2-butene does not exhibit a signal in the double-bond region of the spectrum (1600–1850 cm−1); however, ir spectroscopy is
Elza [17]
However <em>trans</em>-2-Butene does not give a characteristic peak in 1620-1680 cm⁻¹ region but still the presence of carbon double bond carbon can be detected by detecting following peaks in IR Spectrum.

1)  3010-3100 cm⁻¹:
                               As in trans-2-Butene a hydrogen atoms ate attached to sp² hybridized carbon, therefore the stretching of =C-H (C-H) bond will give a peak of medium intensity in the range of 3010-3100 cm⁻¹.

2)  675-1000 cm⁻¹:
                             Another peak which is given by the bending of =C-H (C-H) bond with strong intensity will appear in the range of 675-1000 cm⁻¹.
