Answer:

Avogadro's Law

Explanation:

The amount of moles is directly proportional to the volume of the gas under constant temperature and pressure. That is the statement of Avogadro's law. The equation is:

V1n2 = V2n1

<em>Where V is volume and n are moles of 1, initial state and 2, final state of the gas</em>

<em />

That means, right option is:

<h3>Avogadro's Law </h3>

Which car has the highest kinetic energy if each car is traveling at a speed of 1 m/s? Explain how you arrived at your answer.
KiRa [710]

Car D

Because it is the heaviest. Kinetic energy is directly proportional to the velocity and mass of the object. All the cars have the same velocity. But Car D has the most mass. So, it has most kinetic energy, because more the mass more the energy.

A gas is produced when 25 g of substance X is mixed into 60 g of solution Z in a beaker. The mass of the solution in the beaker
Zepler [3.9K]

mass of the gas = 10 g

<h3>Further explanation</h3>

<em>The law of conservation of mass :</em>

<em>In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.</em>

Reaction

\tt X+Z\rightarrow gas+solution

mass before reaction=mass after reaction

\tt 25+60=gas+75\\\\gas=25+60-75=10~g

Neon atoms are known to produce a mass spectrum that consists of three peaks at m/z values of 20, 21 and 22, with the relative a
wel

Answer:

Explanation:

m / z = 20 , 21 , 22

m / 1 = 20 , 21 , 22

m = 20 , 21 , 22 .

ratio of isotopes = 112 : 0.21 : 11.1

Average atomic mass = (112 x 20 + .21 x 21 + 11.1 x 22) / (112 + .21 + 11.1 )

=  (2240 + 4.41 + 244.2) / 123.31

= 2488.61 / 123.31

= 20.18

Your experiment requires 150 mL of 7.7 M NaOH. How many grams of NaOH will you need?
Elodia [21]
You have molarity and you have volume. Use the formula :
Molarity(M)= Moles(N)/Liter(L)            to get the solution. 
150 ml= .150 L
7.7 = N/.150
N=.1.155 moles of NaOH.
 And since you know the moles, use the molar mass to figure out the grams.
<span> (40g/mol NaOH) x (1.155mol) =  
46.2 g of NaOH.</span>
