Answer:
Photosynthesis takes place in the chloroplasts of cells. ... While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants perform both photosynthesis and respiration, while animals can only perform respiration.
The law of conservation of mass states that mass is an isolated system and is neither created nor destroyed.
Applying this concept on a chemical reaction means that the total mass of reactants should be equal to the total mass of the products.
In this question, we have gasoline and oxygen as reactants and we have carbon dioxide and water as products.
Based on the law, the sum of the masses of oxygen and gasoline is equal to the sum of masses of carbon dioxide and water.
Therefore,
mass of carbon dioxide and water = 22 + 86 = 108 kg
Answer:
What is the net ionic equation for a reaction between HCl and NaOH?
Explanation:
A salt is a neutral ionic compound. Let's see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl
Hope that helped.
Answer : Salt and Sand are weighed and kept in different 50 Milliliter beakers because, the experiment is about studying and separating the homogeneous mixture. As salt crystals are cubic and sand grains are rounded oblong grains. If we mix it together it would require a physical method to separate them. So, before starting the experiment it needs to be weighed in different beakers.
