Answer:
Explanation:
The chlorine is present in group 17. It has seven valance electrons. It accept one electron to complete the octet and show -1 charge and from anion.
Cl⁻
Sodium is present in group one. It alkali metal. It loses one valance electron and show +1 charge. It form sodium cation.
Na⁺
Magnesium is present in group two. It loses its two valance electrons and show +2 charge. It form magnesium cation.
Mg⁺²
Oxygen is present in group 16. It has six valance electrons. It require two electrons to complete the octet and show -2 charge.
O⁻²
Aluminium is present in group 13. it has three valance electrons. It loses its three valance electrons and show +3 oxidation state
Al⁺³ (most common)
others = Al⁺¹, Al⁺²
Iron is present on group eight.
Fe⁺² , Fe⁺³ (most common)
others = Fe⁺⁴, Fe⁺⁵
Copper is present in group eleven.
Cu⁺¹ Cu⁺²
other = Cu⁺³
Zinc is present in group twelve. -2, 0, +1 , +2
Zn⁻², Zn⁺¹, Zn⁺²
A ecosystem is SUSTAINABLE if it can continue to function over long periods of time.
Panacetin is a mixture of three components: sucrose, aspirin and tylenol. To determine the arrangement of layers, you must research on the densities of the components. The densities of sucrose, aspirin, and tylenol are 1.59 g/mL, 1.4 g/mL and 1.26 g/mL. The more dense the component, the farther it sinks to the bottom. Thus, the topmost layer is tylenol, followed by aspirin, and the bottom layer is sucrose. <em>Therefore, aspirin is placed in the second layer.</em>
Answer: 3 molecules of carbon dioxide and 4 molecules of water are produced during the combustion of propane.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction for combustion of propane is:
3 molecules of carbon dioxide and 4 molecules of water are produced during the combustion of propane.
