Answer:

295.96 K    (  = 22.81 degrees C)

Explanation:

PV = n RT    R = .082057 L-Atm / (K-Mol)     n = 3.5   P = 1 atm    V = 85 liters

(1)(85) = 3.5 (.082057)(T)

solve for T = 295.96 K

How many grams of oxygen gas (02) are needed to completely react with 9.30 moles
Luba_88 [7]

Answer:

223 g O₂

Explanation:

To find the mass of oxygen gas needed, you need to (1) convert moles Al to moles O₂ (via the mole-to-mole ratio from reaction coefficients) and then (2) convert moles O₂ to grams O₂ (via the molar mass). When writing your ratios/conversions, the desired unit should be in the numerator in order to allow for the cancellation of the previous unit. The final answer should have 3 sig figs because the given value (9.30 moles) has 3 sig figs.

4 Al + 3 O₂ ----> 2 Al₂O₃
^         ^

Molar Mass (O₂): 32.0 g/mol

9.3 moles Al          3 moles O₂              32.0 g
-------------------  x  ---------------------  x  --------------------  =  223 g O₂
                              4 moles Al               1 mole

The density of ethanol is 0.789 g/mL. Calculate the volume of 600 g of ethanol.
Anettt [7]

Answer:

The answer is

<h2>760.46 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of ethanol = 600 g

density = 0.789 g/mL

It's volume is

volume =  \frac{600}{0.789}  \\  = 760.4562737...

We have the final answer as

<h3>760.46 mL</h3>

Hope this helps you

Which list represents the classification of the elements nitrogen, neon, magnesium, and silicon, respectively?
serious [3.7K]
The question is incomplete. Complete question is:
Which list represents the classification of the elements nitrogen, neon, magnesium, and silicon, respectively?
(1) metal, metalloid, nonmetal, noble gas
(2) nonmetal, noble gas, metal, metalloid
(3) nonmetal, metalloid, noble gas, metal
(4) noble gas, metal, metalloid, nonmetal
.................................................................................................................

Answer: The correct answer is option 2) nonmetal, noble gas, metal, metalloid

Reason: 
1) Non-metal are bad conductors of electricity. Also non-metal are electronegative in nature. Hence, among the provided elements, nitrogen satisfied the criteria. Hence, it is a non-metal.

2) Noble gas are the elements which have completely filled outermost shell. Hence, among the provided elements, Neon satisfied the criteria.

3) Metal are good conductors of electricity. Also metal are electropositive in nature. Hence, among the provided elements, magnesium satisfied the criteria. Hence, it is a metal.

4) Metalloid have conductivity better than non-metals but poor than conductors. Hence, among the provided elements, Silicon satisfied the criteria. Hence, it is a metalloid.
