Let's start from the Fluorine (F), which has 4 atoms on the right side: this means we must put a factor 4 in front of HF to balance the number of atoms of Fluorine.
Nowe we have 4 atoms of hydrogen, H, on the left side. Since we have a

on the right side (2 atoms), we must put a factor 2 in front of

, to balance the number of atoms of hydrogen.
So now the atoms of oxygen are also balanced (2 on both sides), as well as the atoms of Silicon (Si), so the balanced reaction is
Answer:
Explanation:
I can give you four for certain.
Copper
Gold
Silver
Aluminum
To compute for the heat,

needed to be absorbed or released, we need

where

is the mass of the alligator,

is the change in temperature, and

is the specific heat of the alligator's body. Plugging in all the information we have,

Recall that 1 Watt = 1 J/s, thus time needed to absorb radiation from the sun is

That means it takes 4250 seconds for the alligator to warm up to be able to absorb the radiation from the sun.
Answer: 4250 seconds
Answer:
Meters
Explanation:"How FAR did the athlete run?"
Also it talked about meters
