Na^+ and NO3^- are spectator ions.

Before we decide on which ions are spectator ions, we need to look at the molecular reaction equation, complete ionic equation and net ionic equation.

The molecular reaction equation is;

AgNO3(aq) + NaCl(aq) -------> AgCl(s) + NaNO3(aq)

The  complete ionic equation is;

Ag^+(aq) + NO3^-(aq) + Na^+(aq) + Cl^-(aq)  -------> AgCl(s) + Na^+(aq) + NO3^-(aq)

The net ionic equation is;

Ag^+(aq) + Cl^-(aq)  -------> AgCl(s)

The spectator ions are those ions that appear on both sides of the complete ionic equation. Hence, Na^+ and NO3^- are spectator ions.

The movement of water between body fluid compartments
Lady bird [3.3K]

Smooth Transitions between Compartments The force that a fluid applies against a wall—hydrostatic pressure—is what moves fluid between compartments.

<h3>Where is fluid compartment?</h3>

Water makes roughly 60% of the adult human body, which is composed of intra- and extracellular fluid compartments. Extracellular fluid, which makes up 13 of the body's water, is found outside of cells. Two-thirds of the water in the body is found inside the mitochondria and is known as intracellular fluid.

<h3>Which body fluid compartment has the least fluid?</h3>

The fraction of fluid volume that is present in the gaps bordered with epithelial cells is known as transcellular fluid. It is the tiniest part of extravascular space, which also consists of plasma and interstitial fluid. Although it is often not expressed as a percentage of extracellular fluid, the body water content is around 2.5%.

A book has a mass of 400g the surface of the book in contact
Brut [27]

Answer:

The pressure exerted on the table due to the book is 200 N/m².

Explanation:

The pressure exerted on the table due to the book is 200 N/m².

The given parameters;

mass of the book, m = 400 g = 0.4 kg

dimension of the table,  = 0.10m x 0.20 m.

gravitational field strength g =  10 N/kg.

The area of the table is calculated as follows;

A = 0.1 x 0.2 = 0.02 m²

The pressure exerted on the table due to the book is calculated as follows; where;

F is the force of the book due to its weight

Thus, the pressure exerted on the table due to the book is 200 N/m².

The professor informs the class that there will be a test next week. what is the probability that a randomly selected student st
marusya05 [52]

The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.

<h3>How to calculate the probability?</h3>

In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.

  • Let S represent studied for.
  • Let B represent a score of B or higher grade

Therefore, we need to find P(S|B):

S|B = \frac{B|S \times S}{B|S \times S\; +\; B|S' \times S'} \\\\S|B = \frac{0.55 \times 0.6}{0.55 \times 0.6 \;+ \;0.2 \times 0.4}\\\\S|B =\frac{0.33}{0.33 + 0.08} \\\\S|B =\frac{0.33}{0.41}

S|B = 0.80.

<u>Complete Question:</u>

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
