Answer:
metal atoms lose electrons to form positively charged ions. non-metal atoms gain electrons to form negatively charged ions
If it goes from a volume of x, then when the volume is doubled it will go to a volume of 2x. If you meant what happens to the pressure, then the pressure halves as volume doubles due to Boyle's law.
The element that has been oxidized is Al ( Answer A)
Explanation
if the oxidation number of an element is greater in the product side than the reactant side then the element has lost the electrons . This mean that the element has been oxidized.
Al is oxidized because it move from oxidation state Zero(0) in reactant side to oxidation state 3⁺ in product side.
This implies that Al loses 3 electrons.
Answer:
P4 + 5O2 --> 2P2O5
2C2H6 + 7O2 --> 4CO2 + 6H2O
Explanation:
Answer: Option (c) is the correct answer.
Explanation:
Photosynthesis is a process in which sunlight, carbon dioxide, and water is used by the plants to make their on food.
Plants absorb energy in the form of heat from the sunlight and thus produce glucose and oxygen from carbon dioxide and water. This absorbed energy is then used to start various chemical and biochemical reactions in the plants.
Hence, photosynthesis is an endothermic reaction.
Thus, we can conclude that a large amount of energy is required to activate the reaction.
