Answer:
false evaporation is change of state
boiling point is temperaturw of liquid
There is a missing portion of this question which shows the reaction that needs balancing:
"In a balanced equation, the same number of each kind of atom is shown on each side of the equation. Calculate the number of iron (Fe), oxygen (O), and carbon atoms (C).
Fe2O3+ 3CO --> 2Fe + 3CO<span>2
</span><span>Based on these values, is the equation balanced?</span><span>"
</span>
To check if this equation is balanced we simply compare the number of each element on each side of the equation.
On the reactant side of the equation we have:
2 Fe atoms
6 O atoms
3 C atoms
On the product side of the equation we have:
2 Fe atoms
6 O atoms
3 C atoms
Therefore, both side of the reaction have the correct and equal number of each atom, so the equation is balanced.
They would collapse as the sun gives the producers energy to grow i.e plants through photosynthesis. Without plants most animals would die out unless humans could somehow create a food in labs without animals or plants for 6 billion people. Ultimately it would be the death of the human race and just about everything on Earth apart from some plants that live in the deep depths of the sea which have adapted to not having as much sunlight.
Answer:
Cold
Explanation:
Particles with lower kinetic energy than molecules in hand would feel cold.
This is because of thermal conductivity, in which hand's molecules with higher kinetic energy will be hot and transfer their energy from higher kinetic energy to lower kinetic energy that would feel cold. <u>Due to high kinetic energy of hand's molecules, it will transfer heat faster to lower kinetic energy particles and a cold sensation will be felt.</u>
Hence, the correct answer is "Cold".
An organism goes through a cycle called development where it grows and changes. Living things can receive energy from their environment (eg:food) and use the energy to grow (get bigger, stronger, etc), develop and reproduce. Living things need energy in order to build up the substances that make up their cells.
Hope this helps! Good luck!
