Answer:

The polarity of a magnet usually means the direction of a vector which points from the south pole of the magnet toward the north pole. ... In this case the polarity is expressed in a way that indicates a circular direction, such as clockwise, or as a perpendicular vector representing the curl of the internal field.

In a permanent magnet, a magnetic field is produced by the composite motions of electrons in geometrically aligned atoms.

A magnetic field is characterized by poles called north and south. Magnetic polarity refers to the orientation of these poles in space.

Need help ASAP please!

bearhunter [10]

Answer:

13 mol NO

Explanation:

Step 1: Write the balanced equation

4 NH₃(g) + 5 O₂(g) ⇒ 4 NO(g) + 6 H₂O(g)

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of O₂ to NO is 5:4.

Step 3: Calculate the number of moles of O₂ needed to produce 16 moles of NO

We will use the previously established molar ratio.

16 mol O₂ × 4 mol NO/5 mol O₂ = 13 mol NO

Question 1 (Multiple Choice Worth 2 points)

Nookie1986 [14]

The scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.

<h3>What are scientific models?</h3>

The scientific models are those which is given by scientists to allow them to make prediction about anything particular on which they are working or making research for it some examples are plum pudding model for an atom and bohr's model of an atom etc.

The biggest advantage is that scientists do not have to check the given data which are written into books they can perform their experiment and can conclude the data by performing experiment.

Therefore, scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.

Convert 64,567 milliliters into nanometers

LiRa [457]

Answer:

64567000000 nanolitres

Explanation:

Base 10 decimal system: 1 milli = 1000000 nano

We simply multiply 64,567 millilitres by 1000000 to get our number in nanolitres:

64567(1000000) = 64567000000 nanolitres
