Lera25 [3.4K]

Answer:

<h2>111 kPa</h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

We have

P_2 =  \frac{13 \times 197000}{23}  =  \frac{2561000}{23}  \\  = 111347.826...

We have the final answer as

<h3>111 kPa </h3>

Hope this helps you

dybincka [34]

Answer:
1. x=4
2.x=\frac{57}{7}
3.x=\frac{27.7}{11}

Explanation:

Given the following questions:

12=3x
7x=57
11x=27.7

In order to find the answers to these questions, we have to recognize that in order to isolate the variable we need to divide on both sides.

Question one:
12=3x
\frac{3x}{3} =\div3
12\div3=4
x=4

Question two:
7x=57
\frac{7x}{7} =\div7
57\div7=8.14285714=\frac{57}{7}
x=\frac{57}{7}

Question three:
11x=27.7
\frac{11x}{11} \div11
27.7\div11=2.51818182=\frac{27.7}{11}
x=\frac{27.7}{11}

Hope this helps.

Why can water dissolve many ionic compounds
ludmilkaskok [199]
To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond. Water is a polar molecule. It has a permanent dipole. ... The negative ions have several water molecules around them, all with their H atoms close to the negative ion
