Answer:
164atm
Explanation:
Given parameters:
Initial pressure = 150atm
Initial temperature = 27°C = 27 + 273 = 300K
New temperature = 55°C = 328K
Unknown:
New pressure = ?
Solution:
At constant volume, the pressure of a given gas varies directly with the absolute temperature.
Mathematically;
= 
P and T are pressure and temperature values
1 and 2 are the initial and new states
Insert the parameters and solve;
= 
300P₂ = 150 x 328
P₂ = 164atm
<h2>Answer:</h2>
They would be arranged in a trigonal planar orientation.
<h3>Explanation:</h3>
If there were only three electron groups around an atom they tend to repel each other and gain a trigonal planar orientation. A molecule with three electron groups orients the three groups as far apart as possible. They adopt the positions of an equilateral triangle 120° apart and in a plane. The shape of such molecules is trigonal planar. An example is BF3:
Answer:
In diseases that still do not have vaccines, humans would have to be much more careful not to have an injury, since vaccines are a way of having antibodies against microorganisms so that we can survive or better defend ourselves against them.
Vaccines are active acquired immunity, this means that a person who is vaccinated acquires new defenses that are manufactured by their own body, that are not vaccinated or that the vaccine does not exist are diseases that could potentiate with the life of the human being or trigger symptoms graves
Explanation:
People who are not vaccinated or suffer from pathologies that do not have vaccines do not have antibodies to fight the microorganism in the first infection, therefore the pathology develops in a much more serious, harmful and even lethal way.
Antibodies are proteins that our body manufactures by inoculating DNA structures, proteins, inactive bacteria, etc. in the form of a vaccine, these proteins are the method of recognition of said microorganism.
Thus generating that once the microorganism enters the body after the vaccine has been placed, it is recognized and eliminated.All this process written simply in the previous text happens in vaccinated people, in those who do not have the vaccine or are not vaccinated. suffer the opposite consequences for lack or deficit of acquired immunity.
Vaccination is a form of active acquired immunization and each country has a different vaccination plan according to the pathologies that prevail in the area to protect the population that lives in them.
When blue vitriol is heated, those water of crystallization escape out of the crystal and what's left is anhydrous copper sulphate or simply CuSO4, without any water of crystallization.
Answer:
MgSO_3(s) + 2 HNO_3(aq) rightarrow Mg^2+(aq) + 2 NO_3^-(aq) + SO_2(g) + H_2O(l) b.
Explanation:
The balanced net ionic equation for the reaction of magnesium sulfite with nitric acid is a. MgSO_3(s) + 2 HNO_3(aq) rightarrow Mg^2+(aq) + 2 NO_3^-(aq) + SO_2(g) + H_2O(l) b.
