Answer: For osmosis to occur the membrane must be
1. permeable to water but impermeable to the solute
2. The concentration of the solute must be different on the two sides of the membrane.
Explanation:
When a light source moves away for an observer.
In a simplified version, check the number carbon atoms present and multiply by its relative atomic mass. Later divide by the given mass (4.5 x 1000 = 4500g) and you’ll get the number of mole of carbon
Answer:
protons
These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number. Protons and neutrons contribute nearly all of an atom's mass; the number of protons and neutrons is an element's mass number
Explanation:
Answer:
Increasing Surface Area
Explanation:
A greater surface area (meaning more, smaller particles) allows for more opportunity for particles to collide. On the other hand, decreasing temperature and removing a catalyst would only decrease the number of collisions, and the clumping option doesn't make much sense. Hope this helps!
