The elements that must be included in an SDS are physical and chemical characteristics, health effects, exposure limits and the origin of the ads.
<h3>What goes in SDS?</h3>
A Safety Data Sheet shows important information about the chemical to be used.
This includes the physical and chemical characteristics of the chemical, and protective measures against its negative effects. The health effects should also be shown.

From the computation, the magnitude of the drag force when the skydiver reached terminal speed is 784 Newtons.
<h3>How to calculate the magnitude</h3>
From the complete information, the skydiver has a mass of 80kg and jumps off a plane. The free-fall acceleration is also given as 9.80m/s².
Therefore, the weight of the skydiver will be:
W = mass × acceleration
W = 80 × 9.80
W = 784N
In conclusion, the magnitude of the drag force due to air resistance is 784N.

One mole of CH₄ reacts with<em> two moles </em>of O₂, producing <em>one mole</em> of CO₂ and<em> two moles</em> of H₂O. Also, one molecule of CH₄ reacts with<em> two molecules </em>of O₂, producing one molecule of CO₂ and<em> two molecules </em>of H₂O.
<h3>
Balance chemical equation</h3>
A balanced chemical equation tells the amounts of reactants and products needed to satisfy the Law of Conservation of Mass.
CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g).
From the chemical combustion of methane given above, One mole of CH₄ reacts with<em> two moles </em>of O₂, producing <em>one mole</em> of CO₂ and<em> two moles</em> of H₂O. Also, one molecule of CH₄ reacts with<em> two molecules </em>of O₂, producing one molecule of CO₂ and<em> two molecules </em>of H₂O.

The garter snakes are distinguished by the three stripes running the length of their body and can often be found in forests, places that are even close to water bodies, and almost any place, even in holes.
