Answer:
The more reactive the metal, the more rapid the reaction is. A metal below hydrogen in the reactivity series will not react with dilute acids.
Explanation:
Valence electrons in metallic bonding occupy whole piece of metal, they do not connected to particular atom,
in ionic they move to more electronegative atom, in covalent bond they between atoms ( covalent polar located closer to more electronegative)
Answer:
Speed = frequency x wavelength 50 cm/s = Freq x 10cm
Explanation:
The percentage error is the error of the measured value to the true value. To find he percent error, the equation is as follows:
Percent error = |Measured Value - True Value|/True Value * 100
The || is needed to get the absolute value of the difference. Substituting the values,
Percent error = |(10.085 g/10 mL) - 0.9975 g/mL|/<span>0.9975 g/mL * 100
</span><em>Percent error = 1.1% </em>
the correct answer is c, c-14 has a half-life of 5, 730 years
