1) False

An anion is a negative ion. When an atom loses valence electrons (i.e. loses negative charge) it becomes a positive ion (called cation, not anion).

2)  True

Non metals are at the right side of the periodic table. Those elements tipically have more than four valence electrons (except C which has 4 valence electrons). Then, by gaining some electrons (the number depends on the number of valence electrons that the non metal has),  they can complete the 8 valence electrons configuration of the nobles gases.

A sample of 5.00 mol of gas in a 10.00 L container is at 45.0 °C. What is the pressure of the gas?
katrin2010 [14]

Answer:

The pressure of the gas is 13, 04 atm.

Explanation:

We use deal gas formula. First, we convert the unit of temperature in Celsius into Kelvin. We use the constant R= 0,082 l atm /K mol.Then, we solve P (pressure).

0°C=273 K   45°C= 273 + 45= 318 K

PV=nRT   -----> P= (nRT)/V

P= (5 mol x 0,082 l atm /K mol x 318 K)/ 10 L

<em>P= 13,038 atm</em>

Which of the following statements about the ordinary IR spectroscopic regions are TRUE? 1. In general, the IR FUNDAMENTAL region
yaroslaw [1]

Answer: the statements in 1 and 2 are true of IR spectroscopic region.

1. In general, the IR FUNDAMENTAL region has a longer wavelength region than the region we call the ultraviolet (uv) region.

2. We can sense some of the frequencies of the FUNDAMENTAL region of the IR as heat

Explanation:

IR has energy value between 10^-5eV - 10^-2eVwhile

UV has energy value of 4eV - 300eV

IR has low photon energy and cannot alter atoms and molecules while UV has sufficient energy to iodize atoms therefore UV has a higher energy band.

Infrared light falls just outside the visible spectrum, beyond the edge of what we can see as red.
