Which one is a redox reaction?
Which one is a redox reaction?
Redox reactions are comprised of two parts, a reduced half and an oxidized half, that always occur together. The reduced half gains electrons and the oxidation number decreases, while the oxidized half loses electrons and the oxidation number increases.
Which one of the following is not a redox reaction?
Complete answer: A . CaCO3→CaO+CO2 is a decomposition reaction . Here in this reaction we can see that there is no change in the oxidation number of any species so it is not a redox reaction.
Which of the following are products of cellular respiration quizlet?
The three products of cellular respiration are ATP energy, carbon dioxide, and water.
What is the primary function of cellular respiration?
The primary function of cellular respiration is to liberate energy in the form of ATP; this is further required to carry out various cellular…
What happens if oxygen is not present for 5 seconds?
The ozone layer is made of oxygen. If the world lost its oxygen for five seconds, the earth would be an extremely dangerous place to live in. Due to the severe sunburn, our inner ear would explode. The air pressure on the earth would drop 21 per cent and our ears would not get enough time to settle.
Will Oxygen run out?
A billion years from now, as the sun heats up, the warmer atmosphere will break down carbon dioxide, killing off plant life, which in turn will shut off Earth’s source of oxygen. All plant and animal life on Earth need oxygen to survive.
What would happen if there was no air on Earth?
If there was no air on earth, plants and animals would not survive. All life forms will cease to exist on the earth resulting in the planets becoming uninhabitable. Moreover the ultra violet rays will fall on earth and cause untold destruction because the atmosphere will lack ozone layer.
What would happen if everyone on Earth held their breath?
The body can only live for approximately six minutes without oxygen, so if the entire human race stopped breathing for ten minutes, we would most likely all die/become unconcious.
What happens if everyone on Earth jumped at the same time?
What if we all jumped at once? Because people are spread somewhat equally around the planet’s spherical surface , if we all jumped in place, nothing much would happen — all our lift-offs and impacts would cancel each other out, resulting in zero net force on the Earth, according to work by physicist Rhett Allain.
What happens if animals are extinct?
What are the consequences of extinction? If a species has a unique function in its ecosystem, its loss can prompt cascading effects through the food chain (a “trophic cascade”), impacting other species and the ecosystem itself.
How does animal endangerment affect us?
When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment. If we allow our environment to become contaminated, we risk our own health.
