Answer:
876 grams
Explanation:
Convert specific gravity to density, using water density 1.0 g/ml
d = e.g x 1.0 g/ml = 1.168 g/ml
d = m/v (mass/volume)
m = dxv = 1.168 g/ml x 750 ml = 876 grams
Explanation: • Electronegativity is the tendency of an atom to attract the electrons in a bond towards it. • Ionization energy is the energy that should be given to a neutral atom to remove an electron from it. The difference in the electronegativity between the two elements is quite small, but the main reason for it is because chlorine is one period below oxygen. Chlorine’s valence electrons are thus less tightly bound than those of oxygen, so they would have lower first ionization energy. Does sodium or potassium have larger ionization energy?
Answer:
B.FeCl₂
Explanation:
there is twice as much chlorine as there is iron
Loose material is compacted by pressure: the weight of the objects beginning to settle on top of it grows until it becomes immense that's how icebergs are formed too
The given question is incomplete. The complete question is ;
Ammonia gas can be prepared by the following reaction:
In an experiment, 27.6 g of ammonia gas, 
, is produced when it was predicted that 50.2 g of would form.
What is the theoretical yield of ? What is the actual yeild of ? What is the percent yeild of ?
Answer: a) 50.2 g
b) 27.6 g
c) 5.0 %
Explanation:
a) Theoretical yield is defined as the amount of the product that is possible in the reaction.
Theoretical yield of = 50.2 g
b) Experimental or actual yield is defined as the amount of the product that is actually formed in the reaction.
Experimental yield of = 27.6 g
c) Percentage yield is defined as the ratio of experimental yileld to the theoretical yield in terms of percentage.
Hence percentage yield for the reaction is 55.0 %.
