There are three specific types of stress.
Compression occurs when pressure pushes in on an object from opposite sides this happens slowly.
Tension occurs when pressure pulls on opposite sides of an object, causing it to stretch this happens quickly.
shear occurs when two objects try to slide past each other in opposite directions this happens not to fast but not to slow.
The negative ion reactions that consist of the formation of carbon dioxide in the atmosphere is generally an exothermic reaction. By definition, an exothermic reaction takes place when the chemical process eventually releases heat as its by-product. It is in contrast in endothermic process wherein heat is absorbed.
When 0.5 moles of Zn react with 0.4 moles of HCL the limiting reactant will be HCL and excess reactant is Zn 0.3 moles excess and 0.2 moles Zn will be consumed in the reaction.
<h3>What is the limiting reactant in the given equation ?</h3>
STEP1- Write the balanced equation
Zn + 2HCL → ZnCl₂ + H₂
STEP2- calculate the moles according to the reaction
1mol of Zn requires → 2moles of HCL
0.5 moles of Zn requires→ 1mol of HCL
Given moles of HCL is 0.4
STEP3- Apply unitary method
0.5/x=1/0.4
0.5×0.4= x
0.2=x
STEP4- excess reagent left 0.5-0.2=0.3
Hence, the 0.3mole of excess Zn is left
