Ionic bond are formed between a metal and a non metal while covalent bonds are formed between two non metals.
ionic compounds include
Na-cl, Mg-Br, Ca-s, Ba-F (are ionic since their bond is between a metal and non metal)
covalent bonds include
O-H, N-O, C-H, F-F, N-H , C-O, F-F ( are covalent since their bond is between two non metal
Answer:
the answer is d which is soap solution because it's a soap solution that can measure the degree of hardness of a water if the water forms with this soap solution then the water is hard but if the water forms foam with soap then it is soft
First write out the balanced equation. 3Cu+2Ag(NO3)3=2Ag+3Cu(NO3)2
Then convert copper from grams to moles
15 g*1 mol cu/63.54 g= 15/63.54 mol cu
Then use the mole ratio to convert Moles Cu to Moles Ag
15/63.54 moles Cu* 2 moles Ag/3 moles Cu
The final awnser is (15*2)/(63.54*3) moles Ag =0.157 moles Ag. If the question wants the answer in grams, convert from moles Ag to grams Ag.
0.157 moles Ag*107.87 g Ag/ mol Ag=16.98 g Ag
Answer:
The O atom will tend to attract the electrons.
Explanation:
The electronegativity of O (3.5) is much higher than H (2.1), which means it is more likely to attract electrons. The higher the electronegativity, the more attractive.
The subscripts indicate the number of atoms of the element immediately before it.
