Explanation:
<h3>Here, mass = 5kg </h3><h3> acceleration = 10m/s^2</h3>
<h3>according to the question ;</h3><h3>F = m×a ( from 2nd law of motion)</h3><h3>F = 5kg × 10m/s^2</h3><h3>F = 50kgm/s^2 or NEWTON </h3>
<h3>SO THE FORCE NEEDED IS 50 NEWTON</h3>

Answer:
Concentration of ammonia = 3M
Explanation:
The reaction for the question is a neutralization reaction between HCl and NH₃
The chemical equation for the reaction is given as
HCl + NH₃ → NH₄CL
1 : 1 1
Volume of HCl = 18.1ml = 0.0181L
Volume of NH₃ = 5ml= 0.005L
Molar concentration of HCl=0.8M
Molar Concentration of NH₃ =?
Number of moles(n)= Molar concentration × Volume
n = C × V
n of HCL= 0.8 × 0.0181
n = 0.01448moles
Since mole ration for the reaction from the balanced equation above is 1:1,
n of NH₃ = 0.01448
molar concentration (C) of NH₃ = n/v
C of NH₃ = 0.01448/0.005
C of NH₃=2.896
C OF NH₃ =3M
A catalyst
A catalyst can be in many forms
The answer is A) Electrons are exchanged.
All reactions that involve molecular oxygen, such as combustion and corrosion, are electron transfer reactions. This includes the rusting of iron.
