Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.
thus, the mass of the reactants in a reaction must be equal to the mass of the products
Answer:
PART A
Explanation:
3. A cylinder of compressed gas has a pressure of 4.882 atm on one day. The next
day, the same cylinder of gas has a pressure of 4.690 atm, and its temperature is
8°C. What was the temperature on the previous day in °C? Ans: 20°C.
Answer:
Explanation:
To compare the average speed, we would need some parameters which you clearly didn't state in your question. However, permit me to manufacture some from thin air.
The formula for average speed is given as
Speed = distance / time
From the question, we have the time, but not the distance moved by the horse. Now, assuming the horse moves a distance of 60 meters, then we can say,
Speed = 60 / 60
Where the difference between the two time, t = 120 - 60 = 180 - 120 = 60
So, from my hypothesized example, the average speed of the horse is 1 m/s
According to ideal gas equation and mole concept, 9.656 g of BrCl is present in the reaction mixture at equilibrium.
<h3>What is ideal gas equation?</h3>
The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.
Substituting the given values in the ideal as equation, n=PV/RT
∴n=1×190/8.314×273=0.083 moles
mass is calculated as number of moles×molar mass
mass=0.083×115.357= 9.656 g
Thus, 9.656 g of BrCl is present in reaction mixture at equilibrium.
