4.50 g of NaCl reacts with 10.00 g of AgNO3 to produce 7.93 g of AgCl. If the theoretical amount of AgCl that can be formed is 8
olga nikolaevna [1]

Answer: 94.07%

Explanation:

Percentage yield can be calculated by the formula

%yield = Experimental yield/Theoretical yield x100

Experimental yield = 7.93g

Theoretical yield = 8.43

%yield = Experimental yield/Theoretical yield x100

%yield = 7.93/8.43 x 100 = 94.07%

A sample of grape juice has a hydroxide ion concentration of 1.4 × 10-10 M.
vodka [1.7K]
<span>grape juice
pOH = -log[1.4*10⁻¹⁰]</span>≈9.6
pH=14-pOH=14-9.6=4.4

orange juce
pH= -log[1.8*10⁻⁴]=3.7

Orange juice has lower pH, so it is more acidic.

Which statement about the elements in the periodic table is true
egoroff_w [7]

A. The number of valence electrons increases as atomic mass increases. == Generally true for the representative elements since atomic mass generally increases with increasing Z.  

B. The reactivity of alkali metals increases as atomic mass increases. == True. Atomic mass increases down the column and so does reactivity  

C. The reactivity of the halogens increases as atomic mass increases. == False. Reactivity decreases down the column.  

D. The number of valence electrons decreases across a period. == False. In general, the number of valence electrons increases across a period, particularly for the representative elements.
