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:
a. 5.36x10⁻⁴ g/mL
b. 4.29x10⁻⁵ g/mL
Explanation:
As the units for concentration are not specified, I'll respond using g/mL.
a. We <em>divide the sample mass by the final volume</em> in order to <u>calculate the concentration</u>:
- 0.268 g / 500 mL = 5.36x10⁻⁴ g/mL
b. We can use C₁V₁=C₂V₂ for this question:
- 8.00 mL * 5.36x10⁻⁴ g/mL = C₂ * 100.00 mL
Answer:
B) The cold air moves faster and pushes the warm air away, causing condensation and rain.
