In an ionic compound, how does the pattern formed by the ions change as the crystal gets larger?

Explanation:

This is an excerpt from my lesson in science:

In an ionic compound, every ion is attracted to ions of opposite charge that surround it. It is attracted to ions above, below, and to all sides. The pattern formed by the ions remains the same no matter what the size of the crystal.

In a single grain of salt, the crystal pattern extends for millions of ions in every direction. Many crystals of ionic compounds are hard and brittle due to the strength of their ionic bonds and the attractions among all the ions.

Hence, it is unchanged.                                      (Brainliest Please and 5 stars)

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

0.700

mol hcl

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

mass of solution = 50.0 ml soln ×

ml soln

= 50.0 g soln

δt=t2-t1

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are

heat from neutralization + heat to warm solution + heat to warm calorimeter = 0

q1+q2+q3=0

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
