Answer:

Metalloids, also known as semimetals are elements containing properties similar and midway between metals and nonmetals. They are found to divide the periodic table between the metals on the left and the nonmetals on the right. Metalloids often have the following properties: could be dull or shiny.

What is the value for ΔS°reaction for the following reaction, given the standard entropy values
Makovka662 [10]
Standard entropy of the compounds of interest are as follows, 
S^{0} (C6H12O6) = 212.1 J/K.mol
S^{0} (O2) = 205.0 J/K.mol
S^{0} (CO2) = 213.6 J/K.mol
S^{0} (H2O) = 69.9 J/K.mol

Now for the reaction: 
<span>C6H12O6(s) + 6O2(g) —->6CO2(g) + 6H2O(l)
</span>
ΔS°reaction = ∑S^{0} products - ∑S^{0} reactants
∴ ΔS°reaction =( 6 S^{0} (CO2) + 6 S^{0} (H2O) ) - (S^{0} (C6H12O6) + 6 S^{0} (O2) = 205.0 J/K.mol)
∴ ΔS°reaction = [6 (213.6) + 6 (69.9 )] - [(212.1) + 6(205.0)]
∴ ΔS°reaction = 258.9 ≈ 262 J/ K mol.

Thus, correct answer is option C

What state of matter is at 35 Celsius
Otrada [13]
Different forms of matter have different melting/boiling points. For example, at 100 degrees Celsius, H2O (water) will turn from lliquid to gas. But NaOH (table salt) doesn't even go from solid to liquid until some 800 degrees Celsius. So, in order to figure out which state matter is at 35 Celsius, you'd have to be more specific about what kind of matter...

A sample of oxygen gas occupies a volume of 250 mL at .8 atm of pressure. What volume will it occupy at 1.2 atm of pressure?
musickatia [10]
167 mL

P1V1 = P2V2
P1 = .8 atm
V1 = 250 mL
P2 = 1.2 atm

Solve for V2 —> V2 = P1V1/P2

V2 = (0.8 atm)(250 mL) / (1.2 atm) = 167 mL
