Answer:
Mass of liquid: 20.421g
Density= 1.0109405940594 g/mL
Explanation:
Mass of liquid
To find mass of liquid you take the mass of beaker + liquid (171.223g) and subtract it from the Mass of beaker (beaker without the water). The difference is the answer.
171.223g - 150.802g = 20.421g
Density
To find density you use the formula Mass/Volume. Take the Volume given, and the mass of the liquid you just found.
20.421mL/20.421g = 1.0109405940594 g/mL
Answer: Extinction
Animals on the verge of extinction are considered endangered species. Some could argue that the phrasing "threatened" is synonymous to "endangered". Some classify extinction based on if the species is completely wiped out in the wild, or if the species is completely gone (both in the wild and in zoos for instance). Extinction events are not solely due to the changes in atmosphere, but also due to lack of food or habitat, among other possible factors.
Answer:
when something is boiling. the temperature increases quickly so B and D are eliminated. So its either A or C. My guess is A
Moles of titrant are lost in the calculation in redox titration.
"The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration.
The equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, is to be detected by the titration. The stoichiometry of the reaction determines how many reactants have been combined at the equivalence point.
Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. In the realm of analytical chemistry, titration is a crucial technique.

Answer:
The answer is "true"
Explanation:
ANP, or ANF, is a human peptide hormone, that controls your blood pressure, a cardiac atrium secretion hormone. It response primarily to the volume and stress expansion of the auricles and ventricles.
- ANP's main function decreases the amount of increased extracellular fluid by increasing renal excretion.
- This hormone is primarily developed by cardiovascular myocytes and, emanates from the wall tension locally, that's why the given statement is true.
