Answer:
2)HF bcz both fluorine and hydrogen are capable of forming only one covalent bond
Explanation:
flourine is short one electron to become stable while hydrogen has only one electron.Hydrogen cant give out its one electron fully thus it will share its one electron with flourine
Ans: B) semiconductor
Photovoltaic cells work by converting light energy to electrical energy. These cells are essentially made of silicon based semiconductors. When photons (light energy) strike the surface of the semiconducting material electrons are let loose. The delocalization of electron creates a flow of charge which produces electricity.
Thus, it is the semiconductor present in a photovoltaic cell which is responsible for converting light to electricity.
They dont have definite shape, high density and volume.
But they can be mixed together very easily
hope you got your answer
Answer:
16 g
Explanation:
Step 1: Write the balanced equation
2 Na + Cl₂ ⇒ 2 NaCl
Step 2: Identify the limiting reactant
The theoretical mass ratio (TMR) of Na to Cl₂ is 46:71 = 0.65:1.
The experimental mass ratio (EMR) of Na to Cl₂ is 10:10 = 1:1.
Since EMR > TMR, Cl₂ is the limiting reactant
Step 3: Calculate the mass of NaCl produced
The theoretical mass ratio of Cl₂ to NaCl is 71:117.
10 g Cl₂ × 117 g NaCl/71 g Cl₂ = 16 g NaCl
, and after the reaction, it has been converted to elemental gold. To make this possible, three electrons must be added to <span>
. This fits within the definition of reduction reactions, where the reactant gains electrons in the reaction.</span>
