Answer:

First law

In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.[2][3]

Second law

In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is assumed here that the mass m is constant – see below.)

Third law

When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

Answer:

an object that is at rest will stay at rest inless a force acts upon it.

An oject that is in motion will not change its velocity unless a force acts upon it.

Which of the following are weak electrolytes in aqueous solutions? Select ALL that apply.
Mandarinka [93]

Answer:

Weak electrolytes are

HgCl2 and NH₃

Explanation:

  • Electrolytes are compounds that conduct electricity while in molten or aqueous form.
  • Electrolytes may therefore be decomposed by passing electric current through them.
  • They may be either strong or weak electrolytes.
  • Strong electrolytes are those that ionize completely to form mobile ions while weak electrolytes ionize partially to generate ions.
  • Examples of weak electrolytes  are HgCl2, NH₃
  • Examples of strong electrolytes are LiOH, HClO₄, and HI.

What is the percent of Cr in Cr2O3
IgorLugansk [536]
The percentage of Chromium in Chromium Oxide is calculated as follow,

Step 1:
           Calculate Molar mass of Cr₂O₃,
Cr = 51.99 u
O = 16 u
So,
     2(51.99) + 3(16) = 103.98 + 48 = 151.98 u

Step 2:
          Secondly divide molar mass of only chromium with total mass of Cr₂O₃ and multiply with 100.
i.e.
                   = \frac{103.98}{151.98} × 100
                   
                   = 68.41 %
So, the %age composition of chromium in chromium oxide is 68.41 %.
