<span>the balanced net ionic equation for the precipitate reaction
</span>
Na2SO4 + Ba(NO3)2 -------------> <span>BaSO4 + Na2(NO3)2
</span><span>the number of moles of sulfate in the sample
M = m /n
M molar mass
m mass
n number of moles
so n =m/M
n = 8.642/233.33=0.037mol
</span>
Answer: B. m = 3
——————————————
Work:
4(m + 3) = 24
4m + 12 = 24
(Subtract 12 on both sides)
4m = 12
m = 3
The answer to the above question is three
10 + 20 + 1 = 31. there are 2 tens place numbers and 1 one ones place number.
Answer:
<h2>Table 2 is correct, you have it wrong</h2>
Step-by-step explanation:
The way we determine if ratios are equivalent is by a proportion. It also helps to know that a foot is 12 inches, so you have the wrong answer. The correct answer is table 2. The way we solve is by dividing the number of inches by 12 to see if we get the number of feet specified on the table.
24/12 = 2
60/12 = 5
72/12 = 6
84/12 = 7
All of these match up to their respective foot measurements.
