<h3>Answer:</h3>

Direction

<h3>Explanation:</h3>

The question is testing on vector and scalar quantities.

What are vector quantities and scalar quantities?

  • Quantities with both magnitude and direction are known as vector quantities while those with only magnitude are known as scalar quantities.

What are the examples of vector and scalar Quantities?

  • Vector quantities examples- Velocity, force, displacement, etc
  • Scalar quantities examples - Speed, distance, temperature, mass, etc

What would be the difference of speed and velocity then?

  • Speed and velocity differ in that velocity has both magnitude and direction (vector quantity) while speed has magnitude only (scalar quantity).

Further Explanation;

  • Velocity refers to the  rate of change in displacement of a body in motion
  • It is given by, Velocity = Displacement ÷ time
  • Speed on the other hand is the rate of change in distance of body.
  • It is calculated by, Speed = Distance ÷ time
  • Displacement is the distance in a specified direction.
  • Velocity and displacement are vector quantity in that they have both magnitude and direction.
  • Speed and distance on the other hand lack direction and thus are scalar quantity since they only have magnitude.

PLS HELP!!
Gnesinka [82]

Answer:

from the 1st equation:

  4NH3                  4NO

  4 *(68)                 4*30

  1216                     X  mass of NO = 536.5 g

from the 2nd Equation

  2NO           2NO2

   2*30            2* 46

   536.5          x         mass of NO2 = 822.6 grams

from the 3rd Equation

  3NO2                         2HNO3

   3*(46)                           2* (63)

     822.6                             X                mass of nitric acid = 751.06 gram

b)  % yields = ( 96.2%* 91.3% *91.4%)= 80.3%

</span><span>
</span><span>Li⁺ (aq) + OH⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → Li⁺ (aq) + Cl⁻ (aq) + H₂O(l)</span><span />

<span>Explanation:
</span>

<span>1) Combine the cation Li⁺ (aq) with the anion Cl- (aq) to form LiCl(s).
</span>
<span>LiCl is a solid soluble substance, a typical ionic compound. So, it will reamain as separate ions in the product side: Li⁺ + CL⁻</span>

<span>2) Combine the anion OH⁻ with the cation H⁺ to form H₂O(l).
</span>
<span>Since, the ionization of H₂O is low, it will remain as liquid in the product side: H₂O(l)</span>

<span>3) Finally, you can wirte the total ionic equation:
</span>
Li⁺ (aq) + OH⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → Li⁺ (aq) + Cl⁻ (aq) + H₂O(l)
