This is a PV=nRT problem, commonly known as ideal gas. For this, we simply need to take what we know and plug it into the equation
Pressure x Volume = moles x ideal gas constant x tempature.
We know our pressure is 589mmHg so we can plug that in. The volume is unknown.
Then, we need to convert 8.45g of CO2 to moles. That is the grams to moles stoichiometry problem. I will not solve the problem for you, however I can set it up for you:
8.45gCO2 1 mole CO2
-------------- x --------------
1 44.01g CO2
At this point, we now have 589 x X= moles.
The ideal gas constant for mmHg should have been given to you, it is 62.4.
Then, we need to convert from celcius to kelvin. To do this, we simply add 273 to 10, since 273 is the standard unit for kelvin.
Now that we have all of our units, we can plug them into the PV=nRT formula, and solve. We are finding the V, so therefore to find it, the P (pressure) needs to equal the nRT. We would multiple nRT together to get an answer, and divide by the pressure to get the missing unit. To make sure you got the right answer, multiply P and V together to see if it equals nRT. And don't forget to round to the least number of sig figs! Hope I could be of help!
Hello!
The coefficients of any chemical compound are located in the front.
We are asked to find the coefficient of CaCl2 when the equation is balanced. Before finding the coefficient, we should determine if the equation is balanced or not.
Right side: 1 Ca, 2 H, 2 Cl
Left side: 1 Ca, 2 H, 2 Cl → This equation is balanced!
Since the compound CaCl2 has no number in from of the compound, the coefficient has to 1.
Therefore, the coefficient for CaCl2 is 1.
Based on the role of ubiquitin in protein deconstruction as stated in the passage, the correct options are as follows:
- to tag waste proteins for recycling in the proteasomes; option A.
- Wastes will build up in vital organs, and the organism will experience disease; option D
- the neurons affected by the ataxin-1 protein buildup are in a region of the brain that manages muscle control; option D.
<h3>What are phrases?</h3>
Phrases refers to a group of words which contains a verb but which on their own do not make complete sense.
In the description of the role of Ubiquitin, it is described as a small polypeptide chain containing 76 amino acids. The main tole of ubiquitin is to tag proteins for deconstruction in the proteasomes.
Therefore, the phrase describes the purpose of ubiquitin is to tag waste proteins for recycling in the proteasomes; option A.
Based on the passage, the statement that describes the overall consequence of proteins containing mutations is: Wastes will build up in vital organs, and the organism will experience disease; option D
Individuals with spinocerebellar ataxia experience loss of muscle control, even though the ataxin-1 protein builds up only in the brain and spinal cord because the neurons affected by the ataxin-1 protein buildup are in a region of the brain that manages muscle control; option D.
In conclusion, mutations in ubiquitin-tagged proteins will result in accumulation in the body since they cannot be deconstructed in the proteasomes.

No, why? Cause if you're winding up the clock it's basically doing what it needs to do. So there's no need for batteries.. I hope my sad sentence make sense :p
