B and C have the same atomic numbers, which means they have the same number of protons, which is the defining part of an element.
Answer:
0.702M
Explanation:
Molarity of a solution, which refers to the molar concentration of that solution can be calculated thus;
Molarity = number of moles (n) ÷ volume (V)
Firstly, we convert 18.5 grams of NaCl to moles using the formula; mole = mass/molar mass
molar mass of NaCl = 23 + 35.5 = 58.5g/mol
mole = 18.5/58.5
mole = 0.32moles
Volume of water (V) = 450mL = 450/1000 = 0.450L
Molarity = n/V
Molarity = 0.32/0.450
Molarity = 0.702M
Answer:
A. Biodiversity can increase the rate of extinction
Explanation:
That statement is false because variety is better for a better ecosystem. With variety more can survive in certain situations that others cant.
Answer:
An unsaturated solution contains less than the most solute that can be mixed with and became part of a liquid at that temperature. ... A supersaturated solution can be prepared by preparing a saturated solution at a higher than desired temperature then allowing it to cool, decreasing the ability to be dissolved in something of the solute
Explanation:
Question: Would an earthquake support the principle of uniformitarianism or the principle of catastrophism? Explain.
Answer: Catastrophism was the theory that the Earth had largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope. This was in contrast to uniformitarianism (sometimes described as gradualism), in which slow incremental changes, such as erosion, created all the Earth's geological features.
Hope this helps, have a good day. c;
