Answer:
Life on Earth with no decomposers would probably not be possible.
Explanation:
This is because decomposers help the environment in many ways

Answer:
There are 5 steps/rules of the ideal gases based on kinetic theory.
Explanation:
1. Particles in a gas are constant moving in random motion.
2. combined volume of the particles is negligible.
3. particles exert no forces on one another
4. any collisions between the particles are completely elastic
5. the average kinetic energy of particles is proportional to temperature in kelvins.
(I had help explaining steps from Sal Khan. I hope this helps! Have a great day!)
Answer:
The pressure will also be halved.
Explanation:
Gay-Lussac's law states that the relationship between temperature and pressure is directly proportional to each other. If the temperature goes up, so will the pressure.
Answer : The chemical formula for the given compound is 
Explanation : Given,
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of
= 45.43 g
Mass of
= 54.57 g
Molar mass of
= 18 g/mole
Molar mass of
= 129.9 g/mole
To formulate the chemical formula, we need to follow some steps:
Step 1: Converting the given masses into moles.
Moles of water =
Moles of
= 
Step 2: Calculating the mole ratio of the given molecule.
For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.4201 moles.
For
= 
For Carbon = 
Step 3: Taking the mole ratio as their subscripts.
The ratio of
= 1 : 6
The chemical formula for the given compound is 
Hence, the chemical formula for the given compound is
