Answer:

Option A. neutral

Explanation:

we know that

The pH is a number that describe the concentration of hydrogen ions in the solution. A solution's pH will be a number between 0 and 14.

A solution with a pH of 7 is classified as neutral.  (pH=7)

If the pH is lower than 7, the solution is acidic.  (pH < 7)

If the  pH is higher than 7, the solution is basic.  (pH > 7)

In this problem we have a solution that has a pH=7

therefore

The solution is classified as neutral

<u>Answer:</u> The correct answer is Option A.

<u>Explanation:</u>

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

Mathematically,

pH=-\log [H^+]

  • If the solution has high hydrogen ion concentration, then the pH will be low and the solution will be acidic. The pH range of acidic solution is 0 to 6.9
  • If the solution has low hydrogen ion concentration, then the pH will be high and the solution will be basic. The pH range of basic solution is 7.1 to 14
  • The solution having pH equal to 7 is termed as neutral solution.

Hence, the correct answer is Option A.

The compound responsible for the characteristic smell of garlic is allicin, c6h10os2. the mass of 1.00 mol of allicin, rounded t
Gemiola [76]

The compound responsible for the characteristic smell of garlic is allicin, that is having molecular formula C₆H₁₀OS₂.

Molar mass of C₆H₁₀OS₂=162.26 g mol⁻¹.

number of moles of C₆H₁₀OS₂=1 mol

So mass of C₆H₁₀OS₂ can be calculated as:


Number of moles of C_{6}H_{10}OS_{2}, n= \frac{Given mass of the }{Molar mass of theC_{6}H_{10}OS_{2}}

1= \frac{Given mass of the C_{6}H_{10}OS_{2}}{162.26}

Given mass of the C₆H₁₀OS₂= 162 g

Anna35 [415]

Answer;

= 64561.95 g/mole

Explanation;

mass of Fe in 100g = .346g

= .346 / 55.8452 moles

= 0.0061957 moles  

These represent 4 moles of Fe in the molecule so moles of hemaglobin

=  0.0061957/4  

= 0.0015489 moles  

these are in 100 g so mass of 1 mole = 100 / 0.0015489

= 64561.95 g / mole

molar mass of hemoglobin = 64561.95 g/mole
