Answer: They are referred to as isotopes, which are a form of an element that has different numbers of neutrons in their nucleus.
Ethylene Burns in the presence of O₂ to produce CO₂ and H₂O vapors;
C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O
According to equation,
22.4 L (1 mole) C₂H₄ reacts completely to produce = 44.8 L (2 moles) of H₂O
So,
1.65 L of C₂H₄ on complete reaction will produce = X L of H₂O
Solving for X,
X = (1.65 L × 44.8 L) ÷ 22.4 L
X = 3.3 L of H₂O
Answer: mass- how much stuff" is in an object
Weight- there is a gravitational interaction between objects
Explanation:
Answer:
B. Carbon dioxide
Explanation:
A catalytic converter is designed and placed in the exhaust of most automobiles to remove harmful gases from escaping into the environment.
The converter uses palladium and platinum which are both catalyst to reduce harmful gases such as nitrogen oxide which causes acid rain, carbon monoxide which affects human haemoglobin and other hydrocarbons into less harmful ones.
The catalytic converter helps to convert carbon monoxide, a product of incomplete combustion of hydrocarbons into less harmful carbondioxde. Carbon monoxide is a very toxic gas. It causes harm to both plants and animals as well.
No because he did have a small idea allowing later
more educated scientist in more modern times to review and find mistakes. This
allowed scientist in more modern times to also have develop theories. Every
idea needs fixing and this is one. Since he was first to know about such atoms
and making the "plum pudding model", he gave scientists some thoughts
or possible ideas as to what a substance would be like after its last piece.
