Answer:
There is no chemical symbol for paper since it is not an element but rather a mixture of several different compounds. Mixtures in two or more phases are heterogeneous mixtures.

Answer:
191.4K
Explanation:
Using the ideal gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question:
n = 4.2moles
P = 5.5atm
V = 12.0 L
T = ?
Using PV = nRT
5.5 × 12 = 4.2 × 0.0821 × T
66 = 0.345 T
T = 66/0.345
T = 191.4K
Answer:

Explanation:
Hello,
In this case, we can use the combined ideal gas law avoiding the usage of the universal ideal gas constant in order to understand the volume-pressure-temperature behavior at constant moles as given on the statement:

Thus, since the temperature must be operated in absolute Kelvin units, we compute the required volume at 1.54 atm and 10.0 °C, considering that the initial STP conditions are 1 atm and 0 °C:

Best regards.
The element with atomic number 71(lutetium) is paramagnetic
This is because all its electrons is not paired . lutetium has electron configuration of (Xe) 4f^14 5d^1 6S^2
Its 5d sub shell is not paired since the d sub shell can accommodate a total of 10 electrons hence lutetium is paramagnetic
