Answer:
Moles of magnesium chloride can be produced are 0.2 moles
Explanation:
The reaction of Mg with Cl2 is:
Mg + Cl₂ → MgCl₂
<em>Where 1 mole of Mg reacts per mole of Cl₂ to produce MgCl₂.</em>
<em />
As the reaction is 1:1, we need to convert the mass of both Mg and Cl₂ to moles. The lower number of moles will determine the moles of MgCl₂ that will be produced:
<em>Moles Mg -Molar mass: 24.3g/mol-:</em>
4.86g * (1mol / 24.3g) = 0.2 moles Mg
<em>Moles Cl₂ -Molar mass: 24.3g/mol-:</em>
21.27g * (1mol / 70.9g) = 0.3 moles Cl₂
As moles of Mg < moles of Cl₂, Mg is limiting reactant and moles of magnesium chloride can be produced are 0.2 moles
Answer:
there are some materials listed so next to it it shows that which material is pure substance and which material is mixture
and then the next shows which is a homologous and homogeneous compound or element
If we draw a Lewis structure of a Phosphorus tetrachloryl ion (PCl+4), the geometry of the ion is tetrahedral. Now, we can measure the bond angle between two of the phosphorus - chlorine bonds. The bond angle for tetrahedral structures is 109.5 degrees.
Answer:
Humans, and most vertebrates, lack the enzyme cellulase.
Explanation:
Cellulose is a polysaccharide and it is made up of glucose however we the humans and other vertebrates lack the enzyme cellulase which is required to break down the cellulose molecule.
Some Animals such as cows, and termites have bacteria in the intestinal tract which can digest the cellulose as it has cellulase enzyme.
Thus due to symbiotic association with bacteria a few animals may digest cellulose indirectly.
