What temperature would be required to keep 0.895mol of gas in a 28.6L tank at a pressure of 0.500atm?

Chemistry
1 answer:
True [87]3 years ago
3 0

Answer:

The temperature would be 194, 8 K.

Explanation:

We use the formula:

PV=nRT --> T=PV/nR

T= 0,500 atm x 28, 6 L/ 0,895 mol x 0,082 l atm /K mol

<em>T= 194,8494345 K</em>

Draw the cis and trans isomers of 2-butene, ch3chchch3. show all hydrogen atoms.
RoseWind [281]
In general chemistry, isomers are two or more elements that have the same number of protons but differ in mass number. In organic chemistry, the compounds are cis or trans isomers if they have the same chemical formula, but differ in the placement of functional groups based on molecular geometry. Cis isomer is when two like functional groups are on the same side of the molecules, while trans isomer is when the like functional groups are on opposite sides. 

The cis-trans isomers are shown in the picture. As you can see, in the cis isomer, the methane functional group are both in the same side. Same as well with the hydrogen atoms. On the other hand, these functional groups are opposite to each other in the trans isomer.

I would classify it as a homogeneous mixture that you can't see different particles in with a human eye but if you look through it in a microscope I would classify it as a heterogeneous mixture because you can see the different sugars and saps.Hope this helped???

Which formula represents lead (ii) phosphate? 1. pbpo4 2. pb4po4 3. pb3(po4)2 4. pb2(po4)3?
IrinaVladis [17]
3.) Charge on one molecule of PO4 is -3. So on two molecule it'll be 2(-3) = -6. Let oxidation number of Pb be x. Therefore, 3x+(-6) = 0. 3x=6. x=2.

How many liters of a 4M solution can be made using 100 grams of LiBr?
REY [17]

Answer:

volume = 0.288 L

Explanation:

To find the volume, you need to (1) convert grams LiBr to moles LiBr (via molar mass) and then (2) calculate volume (via molarity equation). It is important to arrange the ratios in a way tat allows for the cancellation of units (desired units in the numerator).

<u>(Step 1)</u>

Molar Mass (LiBr): 6.9410 g/mol + 79.904 g/mol

Molar Mass (LiBr): 86.845 g/mol

100 grams LiBr           1 mole
-----------------------  x  ------------------  =  1.15 moles LiBr
                                  86.845 g

<u>(Step 2)</u>

Molarity (M) = moles / volume (L)

4 M = 1.15 moles / volume

(4 M) x volume = 1.15 moles

volume = 1.15 moles / 4 M

volume = 0.288 L
