How many significant digits are 6.3590x10 7 mm

2 answers:

8 0

If you go by the decimal there should be 5 significant digits because 0 is a trailing zero and matters since it comes after a decimal. however if you do

6.3590 x 10 ^7 = 63590000 then you would only have 4 significant digits because there is no longer a decimal to make the zero after the 9, significant.

Hope this helps!

Answer:

There are 5 significant digits

Explanation:

Significant digits are essentially numbers that contribute directly towards a measurement. There are certain rules to be followed while identifying the number of significant digits in a measurement, these include:

1) Non-zero digits are significant

2) Leading zeros are insignificant

3) Trailing zeros only after a decimal point are significant

4) Zeros in between non-zero digits are significant

The given value is:

6.3590*10⁷

There are 4 non-zero digits + 1 trailing zero after the decimal.

Therefore, significant digits are 4 + 1 = 5

Is a forward or reverse reaction favored?

Alex Ar [27]

Answer:

(a) $CH_3COOH \rightleftharpoons CH_3COO^-+ H^+$ : reverse reaction is favored.

(b) $AgCl \rightleftharpoons Ag^+ + Cl^-$ : reverse reaction is favored.

(d) $A+B\rightleftharpoons C$ : forward reaction is favored.

Explanation:

Hello,

(a) $CH_3COOH \rightleftharpoons CH_3COO^-+ H^+$ :

In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (acetic acid) will tend to have a higher concentration.

(b) $AgCl \rightleftharpoons Ag^+ + Cl^-$ :

In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (silver chloride) will tend to have a higher concentration.

In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (aluminium hydroxide) will tend to have a higher concentration.

(d) $A+B\rightleftharpoons C$

In this case, since the Ka is greater than 1, we infer the forward reaction is favored since the product (C) will tend to have a higher concentration.

Regards.
