Answer:
C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.
Explanation:
The products of a reaction contains a certain number of each atom constituting each product;
Matter cannot be created or destroyed so the reactants must contain the same number of each atom;
Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed
Answer:
Due to urease activity, bacteria are able to use urea as a sole nitrogen source and produce ammonia, which increases the pH in the proximal environment, causing Ca2+ and CO32- to precipitate as CaCO3.
Answer:
B
Explanation:
The statement typically depicts Ohm's law which can be mathematically represented as, I = V/R or V = IR. This representation means that as the current increases, the voltage also increases.
<span>The chaparral is characterized by sparse, rough terrain and nutrient-poor soil meaning that no single resource is overly abundant. Therefore, a varied diet allows an animal to make use of a wider selection of the resources that are available to it and thereby thrive.</span>
