Answer:

Explanation:

Explanation

Periodic tables vary in how many places of sig digits they show. I always use approximate values which means that you will have to redo the question using your values

Water (1 mole)

2 * H =  1.01 * 2 = 2.02

1 * O = 16 <u>* 1 =   16.00</u>

Mass 1 mole =   18.02

Moles water

given mass = 22.45

molar mass = 18.02

moles = given mass/ molar mass

moles = 22.45 / 18.02

moles = 1.246 moles

Answer:

1.247mol

Explanation:

moles=mass/molar mass

molar mass of water = 1+1+16=18

mass = 22.45

22.45÷18

= 1.247 moles of water

When the medium is unifrom, how do light waves travel though it?​
Sindrei [870]

Answer:

Light waves travel in straight lines through a vacuum or a uniform medium. They vary only in wavelengths but they typically consist of periodic oscillations of both electric and magnetic fields. These are generated by charged particles that traverse through straight line in a vacuum.

What is the 10% rule? What is its significance? Why is energy lost?
TEA [102]
The 10% rule means that approximately there will be only 10% energy transferred from a trophic level into another. That was because the consumer on the upper level will use the energy before it was consumed. About 90% of the energy used so only 10% remain will be transferred.
Example: an antler eating grass with a total 100 calories. Then the antler is moving and growing, using 90 calories. Then a lion eats the antler, but the energy remains is only 10 calorie because 90 calories are already used.
