W=(m'/m)·100%
m'=37.2 g
m=48.5 g
w=(37.2/48.5)·100%=76.7%
Answer:
True
Explanation:
Ionic bonds are formed by complete transfer of electronic from one to another atoms. The metals are electron donor and non metal are the electron accepter.
Consider the example of sodium chloride. Sodium is metal and chlorine is non metal. Sodium is present in group one and have one valence electron. It loses one electron and get stable electronic configuration.
While chlorine is present in group 7A and have seven valence electron. It require one more electron to complete the octet. Thus hen sodium and chlorine the electron lose by sodium is accepted by chlorine and form ionic compound.
The compound having ionic bonds generally have moderate to high boiling points and melting point because of greater electrostatic interaction. Their electrical conductivity are high and these minerals tend to dissolve in water.
Answer: Hello your question is poorly written attached below is the complete question
answer:
450 kg
Explanation:
mass of product formed = mass of reactants that reacted
hence :
mass of compound C that can be formed and shipped
= mass of A + mass of B
= 200 kg + 250 kg = 450 kg ( theoretical mass of compound formed )
Answer:
nonrenewable
Explanation:
It's just an educated guess but you know plastic bottles and stuff like that contribute to pollution
Answer:
Zn + 2HCl => ZnCl2 + H2
Explanation:
This equation represents salt formation or salt preparation. Thus not a neutralization reaction.
