False. A buffering solution consists of a WEAK acid such as CH3COOH, C5H5N, or ammonia. <span>A buffering solution resists pH change upon the addition of an acidic or basic components. It can neutralize little amounts of added acid or base, thus maintaining the pH of the solution relatively stable. The correct answer is letter "B. false"</span>

makkiz [27]

Answer:

Sal, cobre, aluminio, anillo de oro puro Oxígeno ------ suspensión.

Cerveza, carbonato de sodio, oxígeno, carbono y helio ------ solución.

Explicación:

Sal, Cobre, Aluminio, Anillo de oro puro Oxígeno son los ejemplos de suspensión porque permanecen suspendidos en la solución mientras que por otro lado, Cerveza, Carbonato de sodio, Oxígeno, Carbono y helio son los ejemplos de solución porque formaron una mezcla homogénea en la que ambas soluciones no se pueden diferenciar entre sí pero en suspensión sí se pueden diferenciar.

A chemist needs 1.25 moles of sugar to dissolve in 1 liter of water how many grams of sugar needed
sdas [7]

Answer:

The mass of sugar used is 427.5 grams.

Explanation:

The formula of common sugar is \mathrm{C_{12}H_{22}O_{11}}.

Its molar mass of molecule is 342 grams per mole.

The number of moles of sugar used is equal to '1.25'

\mathbf{Mole=\frac{Mass \ given \ in \ grams}{Molar \ mass \ of \ molecule \ in \ grams}}

\textrm{Mass in grams}=\textrm{Mole} \times \textrm{Molar mass of molecule in grams}

\textrm{Mass in grams}= 1.25\times342

\mathbf{Mass \ in \ grams=427.5 g}

(NOTE : <em>You can calculate molar mass by adding the mass of all the atoms present in the atom. </em>

<em>Mass of Oxygen (O) = 16  ;  Total number of Oxygen atoms present = 11</em>

<em>Mass of Hydrogen (H) =1  ;  Total number of Hydrogen Atoms present = 22</em>

<em>Mass of Carbon (C) = 12   ;  Total number of Carbon atoms present = 12</em>

<em>Total mass of molecule = 12 × 12 + 1 × 22 + 16 × 11 = 342</em>)
