Answer:

2.52atm for sure

Explanation:

We know that:

P1= 2.80atm

T1= 400k

T2= 360k

And we want to find P2= ?

We have an equation: P1/T1 = P2/T2

Multiple both side by T2 to remove it

P2 = 2.52

Caustic soda is 19.1 M NaOH and is diluted for household use. What is the household concentration if 10 mL of the concentrated s

olga nikolaevna [1]

Hello!

To calculate the household concentration of NaOH we need to use the dilution formula, clearing for M2, as you can see in the equation below:

$M1*V1=M2*V2 \\ \\ V2= \frac{M1*V1}{V2}$

Now, we input the values from the data we have onto this equation. M1=19,1 M; V1=10 mL; V2=400 mL, and solve the equation to get the result:

$V2= \frac{M1*V1}{V2}= \frac{19,1M*10mL}{400 mL}=0,48M$

So, the household concentration of NaOH will be 0,48 M

Have a nice day!

Why do some atoms form positive ions and others form negative ions?

kenny6666 [7]

It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.

The electron affinity of the neutral atom of the element can show indicate whether or not the element is going the make positive or negative ions. The higher the electron affinity is, the more the neutral atom wants to gain electrons. The electron affinity for alkali metals and alkaline earth metals are low due to the fact that they are located on the left of the periodic table and only needs to loose 1 or 2 electrons to have a completed valence shell. That means that they want to form cations (loose electrons). Halogens have a high electron affinity since they are located on the right of the periodic table and only have to gain 1 electron to get a completed valence electron configuration. That means that it forms anions.

I hope this helps. Let me know if anything is unclear.
