Newton's first law of motion predicts the behavior of objects where all existing forces are balanced. Objects at equilibrium will not accelerate. Also, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.

Newton's second law of motion: behavior of objects for and all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object  is increased, the acceleration of the object is decreased.

Can you dissolve. 35 moles of potassium permanganate (kmno4) into 500 ml of water? _________ why? / why not?
Greeley [361]

Yes, we can dissolve 35 moles of KMnO₄ into 500 mL of water to give a molarity of 70 M

<h3>What is molarity? </h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the molarity </h3>
  • Mole of KMnO₄ = 35 moles  
  • Volume = 500 mL = 500 / 1000 = 0.5 L
  • Molarity =?

Molarity = mole / Volume

Molarity = 35 / 0.5

Molarity = 70 M

A mixture of N2, O2, and Ar has mole fractions of 0.25, 0.65, and 0.10, respectively. What is the pressure of N2 if the total pr
s344n2d4d5 [400]

Answer:

Partial pressure of nitrogen gas is 0.98 bar.

Explanation:

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gases.

P=p_{N_2}+p_{O_2}+p_{Ar}

p_{N_2}=P\times \chi_{N_2}

p_{O_2}=P\times \chi_{O_2}

p_{Ar}=P\times \chi_{Ar}

where,

P = total pressure = 3.9 bar

p_{N_2} = partial pressure of nitrogen gas  

p_{O_2} = partial pressure of oxygen gas  

p_{Ar} = partial pressure of argon gases  

\chi_{N_2} = Mole fraction of nitrogen gas  = 0.25

\chi_{O_2} = Mole fraction of oxygen gas  = 0.65

\chi_{Ar} = Mole fraction of argon gases = 0.10

Partial pressure of nitrogen gas :

p_{N_2}=P\times \chi_{N_2}=3.9 bar\times 0.25 =0.98 bar

Partial pressure of oxygen gas :

p_{N_2}=P\times \chi_{O_2}=3.9 bar\times 0.65=2.54 bar

Partial pressure of argon gas :

p_{N_2}=P\times \chi_{Ar}=3.9 bar\times 0.10=0.39 bar

at which type of plate boundary do most earthquakes occur? A.convergent B.transform C.divergent D.trench
tino4ka555 [31]

Answer: A. convergent

Most earthquakes occur at the boundary where two plates meet. This phenomena is called as convergent plate tectonics. In this phenomena the two plates moves towards each other. If the plates are of equal density then they will push each other but if they are of unequal density, the denser plate sink beneath the other plate.
