Answer:
Measure the diameter of the circle using Ruler A and Ruler B.
Given that the actual diameter of the circle is 2.264 cm, classify the following statements that describe the diameter measurement of the circle according to the ruler.
Drag the appropriate items to their respective bins.
Answer:
NaCl
Explanation:
because He which is helium gas its an element alone,
Cl which is chlorine is a single element,
B which is Boron and its a single element,
but NaCl which is simply called table sugar is the combination between Na, sodium and Cl, chlorine , so its called a compound not an element.
Answer:
cis 2,3-dibromo- 2-butene
trans 2,3-dibromo- 2-butene
Explanation:
The cis-trans or geometric isomerism is due to restricted rotation around a carbon-carbon bond. This restriction may be due to the presence of double bonds or cycles.
The carbon-carbon double bond prevents free rotation of atoms in molecules. These two molecules have the same atoms, but they are different molecules. They are geometric isomers to each other.
The given compound can exist in the form of two isomers, cis and trans. The isomer that has the substituents on the same side is called cis, and the one that has them on opposite sides is trans.
Answer:
Anode:
3Mg(s) ----------> 3Mg2+(aq) + 6e
Cathode:
2Al3+(aq) +6e ---------> 2Al(s)
Explanation:
Anode:
3Mg(s) ----------> 3Mg2+(aq) + 6e
Cathode:
2Al3+(aq) +6e ---------> 2Al(s)
Magnesium is more electro positive than aluminum hence it functions as the anode. Six electrons are lost/gained in the redox process as shown in the oxidation and reduction half reaction equations above. Magnesium is oxidized to magnesium ion while aluminum is reduced to elemental aluminum.
