Seen in the Water

I am seen in the water
If seen in the sky,
I am in the rainbow,
A jay’s feather,
And lapis lazuli.

Blue.

I Have Four Pairs of Letters

I have four pairs of letters,
Leaving two to stand alone.
You’re often doing the opposite,
When playing on your phone.

I help you get things done,
With one big caveat,
If taken to extremes,
I could make you fat.

What am I?

Efficiency. Being efficient helps you get things done, but if you’re extremely efficient with your tasks you get less exercise.

If I’m Ever Gone, Beware

Sometimes you’ll find me hard and cold,
Other times I’m hard to hold,
Always present in the air,
If I’m ever gone, beware.

What am I?

Water. As ice I’m hard and cold, as water vapor I’m hard to hold and I’m always present in the air as humidity (aka water vapor). If the earth ever runs out of water, we’re toast.

Sum of 22

Fill in numbers such that the sum of each 3-character row is 22 while the sum of all five numbers is 30.

a
bcd
e

The problem works out to a set of three equations:
b + c + d = 22
a + c + e = 22
a + b + c + d + e = 30

Solving for c = 14, leaving d = 8 – b and e = 8 – a. In other words, c must be 14, but the other two numbers just have to add up to 8. The requirement that they be unique rules out 4 + 4, so you’re left to choose from the following combations for b + d and a + e:
0 + 8
1 + 7
2 + 6
3 + 5
