Answer:
Explanation:
Let's break it down:
- Butane- A 4 carbon alkane
- Methyl - A CH₃ group
- 2,2 - Both the Methyl groups are attached at carbon 2
We can now draw the structure of 2,2-dimethyl butane using the following steps:
- Draw the backbone (butane)
- Draw the substituents (2 methyl groups at carbon 2)
The initial volume of the gas is obtained as 11.02 L.
<h3>What is the initial volume?</h3>
The work done can be obtained from the use of the formula;
W = PΔV
W = work done on the gas
P = pressure of the gas
ΔV = Change in volume
Now we can see that;
Internal energy = 127.5 J or 1.26 Latm
Heat lost = 34.7 J or 0.34 Latm
We now have;
-1.26 = 0.34 - 0.900(12.80 - V1)
-1.26 = 0.34 - 11.52 + 0.9V1
-1.26 + 11.18 = 0.9V1
V1 = -1.26 + 11.18 / 0.9
V1 = 11.02 L

Answer:
The specific heat capacity of a metal is 1.31 J/g°C = C
Explanation:
A classical excersise of calorimetry to apply this formula:
Q = m . C . ΔT
177.5 J = 15 g . C (34°C - 25°C)
177.5 J = 15g . 9°C . C
177.5 J /15g . 9°C = C
1.31 J/g°C = C
Answer:
The correct answer is Polar structure. See the explanation below, please.
Explanation:
The water molecule is formed by the union of an oxygen atom (O) to two hydrogen atoms (H), forming at an angle of 105 °, having the negative electron density over the O and positive over the H. The water due to its polarity can interact with other equal molecules, by hydrogen bridge (occurs between the atom of H and an electronegative element, in this case the O). It corresponds to a type of dipole-dipole interaction.
Answer:
Their weight.
Explanation:
Weight is the measurement of gravity pushing you down, so with less gravity there would be less weight.
