The answer is:
It is a measure of the strength of the bonds between ions.
Lattice energy is an estimate of the strength of the bonds formed by ionic compounds.
The first two choices are wrong because it is actually the opposite.
- As the ion size increases, lattice energy <u>decreases</u>.
- As charge of ions increases, lattice energy <u>increases</u>
As for the other third option, it is wrong because lattice energy is the energy RELEASED not absorbed.
Answer:
<h2>250 m/s</h2>
Explanation:
The speed of the car can be found by using the formula
<h2>v = a × t</h2>
where
a is the acceleration
v is the speed
t is the time
From the question we have
v = 10 × 25
We have the final answer as
<h3>250 m/s</h3>
Hope this helps you
Answer:
If one were to use 5 billion years as the age of the universe and 75 years as the average human life span then
T = 75 / 5 E9 = 1.5E-8
The number of seconds in a year is 3600 * 24 * 365 = 3.2E7
If t = N * T seconds in a year * fraction of human life span
t = 1.5E-8 * 3.2E7 = .48
A human life span is about 1/2 second compared to the life of the universe if the universe were compressed to a single year
It has 178200000 ms^-1 and the train has 25200000ms^-1.
