Answer:
Law
Explanation:
A law is a summary of observed (measurable) behavior, whereas a theory is an explanation of behavior. A law tells what happens; a theory (model) is our attempt to explain why it happens.
Answer:
22g
Explanation:
Given parameters:
Mass of element A = 18g
Mass of element B = 4g
Unknown:
Mass of compound formed = ?
Solution:
The reaction equation is given as;
A + B → AB
According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
Simply mas is conserved and the mass of the reactants is the same as the mass of the product that forms.
Mass of reactants = mass of A + mass of B = 18g + 4g = 22g
So;
Mass of product AB = 22g
Answer:
A water molecule displays polarity by having negative and positive ends. Due to this charge difference, a water molecule is called a dipole.
Explanation:
Answer:
it has 7 electrons and it react to the elements with only 1 valence electron, which are elements in group 1
Explanation:
No because they are both made up of H2O molecules; they only have different physical properties, one is in liquid state while the other is in solid state
