    (Elsevier, 2023) Ullah, Zia; Abbas, Amir; El-Zahar, Essam R.; Seddek, Laila F.; Akgul, Ali; Hassan, Ahmed M.
    The main focus of the current research is to evaluate heat and mass transfer across stretchable sheet under applied magnetic field. The chemical reaction and variable density is essential for thermal behavior of nanofluid. The present study presents a careful inspection of chemical reaction, thermal density, viscous dissipation and thermophoresis on heat and mass transfer of magneto and chemically reactive nanofluid across the stretching sheet. The physical attitude of entropy and chemical reaction improvement rate in magneto nanofluid is the primary focus of the present research. By applying the proper transformation, nonlinear partial differential ex-pressions are introduced to the structure of the ordinary differential framework. The flow equations are simplified into nonlinear differential equations, and these equations are then computationally resolved via an efficient computational technique known as Keller box technique. The governing flow factors like Eckert number, reaction rate, density parameter, magnetic-force parameter, thermophoretic number, buoyancy number and Prandtl number on velocity, temperature distribution and concentration distribution are evaluated prominently. It is noticed that prominent enhancement in temperature of fluid is assessed for maximum Prandtl number. It is found that the reasonable change in concentration distribution is evaluated for each Prandtl number with en-tropy generation. It is examined that the dimensionless Nusselt coefficient is decreased for maximum Brownian motion. It is seen that the dimensionless mass transfer is increased for maximum Brownian motion in the presence of buoyancy and magnetic forces.
