Answer:
mass
Explanation:
The triple beam balance is an instrument used to measure mass very precisely.
The Kinetic Molecular Theory has 5 main tenets, and they basically explain that the gas molecules are in constant motion. It is random and it causes constant collisions between the particles and also with the container's walls.
So, the answer is B. Kinetic Molecular Theory.
Answer:
2 mol of CO₂
Solution:
The reaction is as follow,
H₂CO + O₂ → CO₂ + H₂O
According to this equation,
1 mole of H₂CO produces = 1 mole of CO₂
So,
2 moles of H₂CO will produce = X moles of CO₂
Solving for X,
X = (2 mol × 1 mol) ÷ 1 mol
X = 2 mol of CO₂
It is called nuclear energy.
Answer:
A oxygen
Explanation:
For plant growth nitrogen, potassium and phosphorous are the three main elements needed. oxygen is expelled from plants. Plants doesn't need oxygen
