4 0

Answer:

28 blocks

Explanation:

Amount: 21 + y

Ratio: 3:1

Total Ratio: 4

1 = yellow blocks

say if 3 is to 1 then 21 is to how many?

21 ÷ 3

= y = 7

= 21 + 7

= 28 blocks

( or you can use the practical method using your fingers )

Shkiper50 [21]
V_{NaOH}=38,1mL=0,0381L\\
C_{m}=0,265M\\\\
n=C_{m}*V=0,265\frac{mol}{L}*0,0381L\approx0,0101mol

m=\frac{1mol*2,1g}{0,0101mol}\approx 207,92g\\\\

Answer:

Thus, random error primarily affects precision. Typically, random error affects the last significant digit of a measurement. The main reasons for random error are limitations of instruments, environmental factors, and slight variations in procedure.

The accepted density of copper is 8.96 g/mL. Calculate the percent error of a student’s measurement which resulted in a density
uranmaximum [27]

Answer:

<h3>The answer is 1.12 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual density = 8.96 g/mL

error = 8.96 - 8.86 = 0.1

We have

p(\%) =  \frac{0.1}{8.96}  \times 100 \\  = 1.1160714...

We have the final answer as

<h3>1.12 %</h3>

Hope this helps you

What would a general formula of an acid always start with? What does the general formula of an acid have to end with? Where woul
NeTakaya
A general formula of an acid always start with H or the hydronium ion. It has to end with an anion. As acids, these compounds are named starting with the prefix "hydro-," then adding the first syllable of the anion, then the suffix "-ic." Hope this answers the question.
