Answer:
C + O2 ⇒ CO2
mole of O2: 18.6/32=0.58125= mole of CO2
⇒ gram of CO2: 0.58125*(12+32)=25.575
Explanation:
Satellite, also called artificial satellite, is a computer-controlled machine or objects that is launched into the space by a rocket, called the launch vehicle and placed in the orbit of a celestial object.
Answer:
Because in elastic collisions there is no heat emission or absorption.
Explanation:
A collision is considered elastic when the total kinetic energy of the study system is conserved during the collision. Since the total kinetic energy is conserved, heat is not emitted or absorbed during the collision. Since the emission or absorption of heat is what produces changes in temperature, If the system remains at a constant temperature, there were only elastic collisions.
Answer:
3.0 moles.
Explanation:
- It is a stichiometry problem.
- The chemical reaction of reacting hydrogen with oxygen to produce water is:
<em>H₂ + 1/2 O₂ → H₂O.</em>
- It is clear that <em><u>1.0 mole of H₂</u></em> reacts with 0.5 mole of O₂ to produce <u><em>1.0 mole of water</em></u>.
- The ratio of the reacting hydrogen to the produced water is 1:1.
∴ The number of moles of water created from reacting 3.0 moles of hydrogen completely with excess oxygen = 3.0 moles.
Answer: 4 A1+3 02 → 2 Al2O3
Explanation: Two different atoms combines together to produce a compound.
