Hi! Science stands for “Systematic Comprehensive Investigation and Exploration of Nature Causes and Effects”.
What is science?
Science is the systematic study of the structure and behavior of the physical natural world. It is also use for experience or can say it is an experience. Scientists are people who test science/experiments for the worlds. Science really is just the study of the nature. Science use math em empathic and logic, which are sometimes called “formal science”.
Subsequent to deciding what number of valence electrons there are in H2O2, put them around the focal iota to finish the octets. The H2O2 Lewis structure has a sum of 14 valence electrons. Hydrogen (H) particles dependably go on the outside of a Lewis structure.
<span>Yes, mass is conserved. When sodium hydroxide (clear solution) and copper sulfate (blue solution) are mixed, they form a copper hydroxide (a blue solid) and sodium sulfate (a clear solution).
This can be tested simply. First weigh the masses (10 g and 57 g, which totals 67 g)) of the two starting solutions prior to mixing. Then mix and allow the reaction to occur and weigh the mass of the mixture (10g + 57 g = 67 g). The two solutions should have the same mass and therefore demonstrate conservation of mass.</span>
Answer:
cell wall
Explanation:
plants are the only cells that have cell walls. no other type of organism have a cell wall
