Answer:
941.4 kPa
Explanation:
To solve this problem, we can use Boyle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:
![p\propto \frac{1}{V}](https://tex.z-dn.net/?f=p%5Cpropto%20%5Cfrac%7B1%7D%7BV%7D)
where
p is the pressure of the gas
V is its volume
For a gas transformation, the equation can be rewritten as
![p_1 V_1 = p_2 V_2](https://tex.z-dn.net/?f=p_1%20V_1%20%3D%20p_2%20V_2)
where in this problem:
is the initial pressure
is the initial volume
is the final volume
Solving for p2, we find the final pressure:
![p_2 = \frac{p_1 V_1}{V_2}=\frac{(102)(48)}{5.2}=941.5 kPa](https://tex.z-dn.net/?f=p_2%20%3D%20%5Cfrac%7Bp_1%20V_1%7D%7BV_2%7D%3D%5Cfrac%7B%28102%29%2848%29%7D%7B5.2%7D%3D941.5%20kPa)
Answer: principal quantum number (n), azimuthal quantum number (l) and magnetic quantum number (m)
Explanation:
According to quantum mechanics, there are three sets of quantum numbers which accurately describes the electrons position; principal quantum number (n), azimuthal quantum number (l) and magnetic quantum number (m). These three quantum numbers are obtained from Schrödinger wave equation.
With the information given most likely in order to find the partial pressure of the gas produced you have to subtract the total air pressure in the collection flask by the atmospheric pressure since you assume that the flask started with atmospheric pressure when it was sealed and then the gas was added as the reaction took place increasing the pressure.
1.44atm-0.95 atm=0.49atm
Answer:
B. When it is obtained by rounding, as in 3.0
Explanation:
Answer: The coefficient for
is 12.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
![C_{10}H_{12}O_4S(s)+12O_2(g)\rightarrow 10CO_2(g)+SO_2(g)+6H_2O](https://tex.z-dn.net/?f=C_%7B10%7DH_%7B12%7DO_4S%28s%29%2B12O_2%28g%29%5Crightarrow%2010CO_2%28g%29%2BSO_2%28g%29%2B6H_2O)
Thus in the reactants, there are 12 molecules of oxygen in balanced chemical equation. Thus the coefficient for
is 12.
