Answer:
Oxegyn
Explanation:
Because Hydrogen is only one particle while oxegyn is two
1) Across the period as one moves from left to right, atomic size decreases.
2) Consider 3rd period elements containing non-metal i.e Si, P, S and Cl.
3) Here, atomic radius of these elements are in following order Si>P>S>Cl.
4) However, electronegative of these elements increases as we move from left to right
5) Thus, the corresponding hydrides have higher electro-negativity difference,as one moves from left to right.
6) Due to this, bond polarity increases from left to right,
7) Increase in bond polarity, results in increasing proton donating capability.
8) Therefore, acidity increases as one moves along the period.
The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.
<h3>What is a Chemical reaction?</h3>
This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.
A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.
When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

#SPJ1
An alloy is the solid solution of a metal or non-metal dissolved in a metal.
Answer:
0.299 moles of PCl5
Explanation:
First form an equation based of given information: P4 + Cl2= 4PCl5
Next balance it: P4 + 10Cl2 = 4PCl5
Take your given value (53.0g of Cl2) and divide it by its molar mass to get moles of Cl2: 53.0g/70.906g = 0.747 moles Cl2
Then, multiply by the molar ratio (10Cl2 to 4PCl5): (0.747 x 4 mol PCl5)/10 mol Cl2 = 0.299 moles PCl5
