A 0.2 M solution of NaCl contains ________ g of NaCl in 1 l of ________.Please Fill in the Blanks.

Answers

Answer 1
Answer:

Answer:

11.7 g in 1 L of water.

Explanation:

Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.

It is defined as mol/ L (number of moles per litre).

0,2 M means we have 0,2 mol/ L

In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol

(1 mol NaCl)/(58.443 g) = (0.2 mol)/(X g)

X= ((0.2 mol x 58.433 g)/(1 mol)

X= 11.69 g

The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.

Based on each person's statements, identify which of the following you AGREE with, and then explain your reasoning. Courtney: “It is obvious that everything that eats plants would die but all the other organisms on the island would be okay.” Jose: “Courtney I think the organisms that eat plants would just learn to eat other things. So initially they might decline in numbers but eventually, their numbers would increase back to their current amount.”Raquan: “I have to disagree with both of you. I think that all of the organisms on the island would die, because at some point even the mammals who don’t eat plants directly would ultimately discover that what they usually ate has already died.” Mike: “I kind of agree with Courtney, except I don’t think that all of the things that eat plants will die. I think the things that eat both plants and animals would live and only those that can’t or won’t eat animals will die.” Keisha: “Mike is right. I would add that since there are fewer things for the larger mammals to eat that we would ultimately see fewer of them on the island.” Alex: “I argue that organisms that eat plants would learn to swim so they can eat the seaweed and algae in the water.”Plzz explain your reasoning!!

How long does nuclear waste need to be safely stored until it’s no longer hazardous

Answers

Nuclear waste:

Atomic waste is one of the most troublesome sorts of waste to oversee on the grounds that it is profoundly dangerous. As indicated by the U.S. Ecological Protection Agency (EPA), atomic waste is arranged into six general classes.

[1-2] These incorporate (1) spent atomic fuel from atomic reactors, (2) uranium factory tailings from mining and processing of uranium mineral, (3) significant level waste from spent atomic fuel reprocessing, (4) low-level waste, (5) transuranic waste from guard projects, and (6) normally happening and quickening agent created radioactive materials.  

The well-being concerns and security issues related with atomic waste present significant limitations on the far reaching utilization of atomic vitality. Because of its b and exceptionally perilous properties, atomic waste is required to be deliberately put away or reprocessed. The putting away and reprocessing are additionally convoluted by the long half existence of the radioactive materials in the atomic waste.

For instance, a portion of the segments can remain half of their hazardous levels even one million years after the fact after generation.

Why are the oldest fossils found in the oldest rock layers?

Answers

Answer:

Explanation:

This is usually because when they first became fossils, they embedded into the ground. Over many years afterwards, more layers came to cover that layer and so on. Newer fossils would be embedded into newer layers. That's why the older ones tend to be found the deeper you look.

Answer: Well probably because of the fact that over time the rocks stack up on top of each other because of weathering and erosion and as they stack they get deeper and deeper, so fossils that were at the top one time will slowly sink as the time progresses.
