Answer:
1240 mmHg
Explanation:
Since volume is being held constant, we can use the following variation of the Ideal Gas Law to find the new pressure.
![\frac{P_1}{T_1N_1}=\frac{P_2}{T_2N_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1%7D%7BT_1N_1%7D%3D%5Cfrac%7BP_2%7D%7BT_2N_2%7D)
In the equation, "P₁", "T₁", and "N₁" represent the initial pressure, temperature, and moles. "P₂", "T₂", and "N₂" represent the final pressure, temperature, and moles. Your answer should have 3 sig figs to match the sig figs of the given values.
P₁ = 825 mmHg P₂ = ? mmHg
T₁ = 303 K T₂ = 273 K
N₁ = 1.50 moles N₂ = 1.50 + 1.00 = 2.50 moles
<----- Formula
<----- Insert values
<----- Simplify denominators
<----- Simplify left side
<----- Multiply both sides by 682.5
<----- Apply sig figs

Answer:
3
Explanation:
In scientific notation, the number of integers in the first part will always be the amount of significant figures.
For example,
1) 1.542505 x 10^17 =7 significant figures
1) 1.54 x 10^17 =3 significant figures
Answer:
C
Explanation:
Red litmus paper is used to identify base solutions. The paper turns blue when it is exposed to base solutions and remains red when exposed to acidic solutions. Therefore, substance I is neutral and substance II is a base.
It results in a combustion reaction
