Q. Explain why magnesium

2 answers:

4 0

Answer:

Why does Magnesium Oxide have a higher melting point than Sodium Chloride? ... As the charge in the ionic lattice in Magnesium Oxide is two times as large, the ionic bonding is stronger so more energy is required to overcome the electrostatic attraction and break down the ionic lattice.

9. A box is pushed 1.5 m to the right in 5 s. What is the box’s average speed to the nearest hundredth of a m/s? *

poizon [28]

Answer:

s = 0.30 m/s

Explanation:

Given data:

Distance travel = 1.5 m

Time taken = 5 s

Average speed of box = ?

Solution:

s = d/t

s = speed

d = distance

t = time

by putting values,

s = 1.5 m/ 5 s

s = 0.30 m/s

When a sodium (Na) atom forms an ion so that it looks like a noble gas with a full valence shell, what will its charge be?

Setler79 [48]

Answer:

I believe 1+

Explanation:

when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1
