<span>C) <u>Colloids</u></span><span>

Colloids have small non-dissolved particles that flow around in the mixture. These particles do not settle over time. When a light is shined on colloids the scattering characteristic of the Tyndall effect are visable.</span>

The pressure caused by a sample of gas is 2.25 atm. 1 atm is
nexus9112 [7]

Answer:

0.326\frac{N}{cm^2}

Explanation:

Hello.

In this case, considering that 1 atm equals 1.01 kPa, we can compute the pressure in kPa first as shown below:

2.25atm*\frac{1.01kPa}{1atm} =3.26kPa

Now, we convert kPa to Pa, considering 1 kPa equals 1000 Pa:

3.26kPa*\frac{1000Pa}{1kPa}=3260Pa

Now, since Pa is equal to N/m², and 1 m equals 100 cm, the pressure in newton per square centimeter turns out:

3260\frac{N}{m^2}*(\frac{1m}{100cm})^2  \\\\0.326\frac{N}{cm^2}

Best regards.

Answer:

1s² 2s²2p³  

Explanation:

If the atom has seven electrons, it is Element 7 (nitrogen).

In the Periodic Table, you count the electrons in all the subshells up to

No. 7.

In the first Period, you have filled the 1s level (2 electrons).

In the second Period, you have filled the 2s subshell (2 electrons) and put three electrons in the 2p subshell.

Thus, the electron configuration is

1s² 2s²2p³

Note how the superscripts tell you the number of electrons in each subshell: <em>2 + 2 + 3 = 7</em>.
