Answer:
The concentration is 0.111 M.
Explanation:
Use dimensional analysis to solve the problem. Since both HCl and NaOH are strong, the dissociate completely in solution.
For this neutralization, the reaction is HCl + NaOH = NaCl + HOH
18.5 mL x
x
x
= 0.002775 moles HCl
Molarity = moles/ Liters
Molarity of HCl = 0.002775 moles HCl / 0.025 L = 0.111 M
Answer:
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Explanation:
Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
