Answer:

true

Explanation

Unbalanced forces can cause an object to change its motion.If an object is at rest and an unbalanced force pushes or pulls the object it will move. Unbalanced forces can also change the speed or direction of an object that is already in motion.

What is the average atomic mass of all of the naturally occurring isotopes of nickel in amu?
My name is Ann [436]
In general chemistry, isotopes are substances that belong to one specific element. So, they all have the same atomic numbers. But they only differ in the mass numbers, or the number of protons and neutrons in the nucleus. In a nutshell, they only differ in the number of neutrons.

For Nickel, there are 5 naturally occurring isotopes. Their identities, masses and relative abundance are listed below

  Isotope                Abundance           Atomic Mass
   Ni-58                    68.0769%              <span>57.9353 amu
   Ni-60                    </span>26.2231%              <span>59.9308 amu
   Ni-61                    </span>1.1399 %               <span>60.9311 amu
   Ni-62                    </span>3.6345%                <span>61.9283 amu
   Ni-64                    </span>0.9256%                <span>63.9280 amu

To determine the average atomic mass of Nickel, the equation would be:
Average atomic mass = </span>∑Abundance×Atomic Mass

Using the equation, the answer would be:
Average atomic mass = 57.9353(68.0769%) + 59.9308(26.2231%) + 60.9311(1.1399%) + 61.9283(3.6345%) + 63.9280(0.9256%)

Average atomic mass = 58.6933 amu

Compare the arrangements of individual particles in solids, liquids, and gases
pochemuha
Solids - particles are very close together (highest density on the list)
Liquids - the particles slide past one another
Gases - particles bounce off of surroundings and the same particles of the gas

What is the concentration created when 380.0g of Pb(NO3)2 is added to 330.0 mL of solution?
Juliette [100K]

The concentration of lead nitrate is 3.48 M.

<u>Explanation:</u>

The molarity can be found by dividing moles of sucrose by its volume in litres. We can find the number of moles of sucrose by dividing the given mass by its molar mass. Now we can find the moles as,

Here mass of Pb(NO₃)₂ is 380 g

Molar mass of Pb(NO₃)₂ is 331.2 g/mol

Number of moles = $\frac{given mass}{molar mass}

                              =  $ \frac{380 g }{331.2 g/mol}

                              = 1.15 moles

Volume in Litres = 330 ml = 0.33 L

Molarity = $\frac{Moles}{Volume (L)}

          = 3.48 mol/L or 3.48 M

So the concentration of lead nitrate is 3.48 M.

Why are moral or ethical questions NOT testable? A. They are questions that are impossible to answer. B. They are better answere
Radda [10]

Answer:

<u>C. The answers depend on people's opinions, not on observations.</u>

Explanation:

Morals are what people <em>think</em> is the right or wrong behavior and the <em>goodness</em> or <em>badness</em> of a character.

Ethics are <em><u>morals</u></em> that <em><u>govern</u></em> a person.

So the answer is C because these answers cannot be seen from the outside.

For example: A PERSONALITY TRAIT is something you can't really see. A PHYSICAL TRAIT is something you <em>can</em> see.

Ethics and morals are like personality traits.
