The answer is number 4 (Chlorine becomes an anion by gaining an electron from sodium). This occurs because Sodium (Na) is a group 1 element, it does not have a high electronegativity. However, Chlorine, a halogen, has a high electronegativity, taking the electron from Sodium, forming an Ionic Bond.
Answer:
Option D: Cations
Explanation:
Do you need only one answer .
Explanation:
Given that,
Volume of a hallow glass sphere is 350 mL
Specific gravity is 1.252
We need to find the weight of the sphere. The ratio of density of substance to the density of water is called specific gravity.
The density of water is 1 g/mL
We know that,
1 pound = 453.592 grams
So,
m = 0.97 lbs
So, the weight of the sphere is 0.97 lbs or 0.97 pounds.
Answer:
1. 0.98 atm
Explanation:
The following data were obtained from the question:
Mass of unknown liquid (m) = 0.3175 g
Temperature (T) = 99 °C
Pressure (P) = 748.2 mmHg
Volume (V) = 145.0 mL
Gas constant (R) = 0.08206 atm.L/Kmol
1. Determination of the pressure in atm.
760 mmHg = 1 atm
Therefore,
748.2 mmHg = 748.2/760 = 0.98 atm
Therefore, the pressure in atm is 0.98 atm.
Well protists quite very as organisms i.e it is hard to say if an organism is a protist. Some main features of protists are that they have
1. A membrane enclosed nucleus
2.They are mainly single celled
Also protista are found mainly anywhere water is present for example damp soil, pools and lakes.
Hope this helps :).
