Convert each temperature to the one asked for.
1. convert 24.8 ˚C to K
2. convert 376 K to ˚C

Pressure 1)466,095 kPa, 2) 101,325 kPa, 3)0,763 atm,77,327 kPa. Temperature 1)297, 8K , 2) 103 °C.

Explanation:

We use the following equivalences to convert the pressure units and use a simple rule of three for the calculation:

1 atm - 101,325kPa

1 atm-760 mmHg

In the case of temperature: 0 ° C = 273 K (to go from Celsius to Kelvin we add 273 and vice versa we subtract 273).

Pressure:

1) 1 atm---101, 325 kPa

   4,6 atm---x= (4,60 atm x 101, 325 kPa)/1 atm= 466,095 kPa

2) 1 atm equals to 101,325 kPa

3) 760 mmHg ---1 atm

580 mmmHg ---x= (580 mmmHg x 1 atm)/ 760 mmHg= 0,763 atm

1 atm---101,325 kPa

0,763 atm---x= (0,763 atm x 101,325 kPa) / 1 atm= 77,327 kPa

Temperature:

1) 24,8 + 273=297,8 K

2) 376 -273=103 °C

chemistry sucks a**

explanation:

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
