Answer:

Hurricanes are not restricted to just the eastern Pacific and the North Atlantic; they also occur in other places where they are known as the tropical cyclone (South Atlantic Ocean, Indian Ocean) or Typhoons (Western Pacific Ocean).

Explanation:

Hurricanes originate in the Atlantic basin, which includes the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico, the eastern North Pacific Ocean, and, less frequently, the central North Pacific Ocean.

Hope this helps:)

A steel container with a movable piston contains 2.00 g of helium which was held at a constant temperature of 25 °C. Additional
shtirl [24]

Answer: D) 1.00 g

Explanation:

According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,

V\propto n

or,

\frac{V_1}{V_2}=\frac{n_1}{n_2}

where,

V_1 = initial volume of gas  = 2.00 L

V_2 = final volume of gas = 3.00 L

n_1 = initial moles of gas  =\frac{\text {Given mass of helium}}{\text {molar mass of helium}}=\frac{2.00g}{4g/mol}=0.500mol

n_2 = final moles of gas  = ?

Now we put all the given values in this formula, we get

\frac{2.00L}{3.00L}=\frac{0.500mol}{n_2}

n_2=0.75mole

Mass of helium =moles\times {\text {molar mass}}=0.75\times 4=3.00g

Thus mass of helium added = (3.00-2.00) g = 1.00 g

Rank the following solutions from lowest to highest vapor pressure.
Fantom [35]

Solution :

When non volatile solute is added to solvent, vapor pressure gets lowered.

Relative lowering in vapor pressure is given :

$\frac{P^0-P}{P^0}$   = $\text{mole fraction}$ of solute

$\frac{P^0-P}{P^0}=x_B$

$P^0$ = vapor pressure of pure solvent

P = vapor pressure of solution

$x_B$ = mole fraction of solute

$x_B=\frac{n_B}{n_A+n_B}$

$n_B $ = $\text{number of moles of solute}$

$n_A$ = $\text{number of moles of solvent}$

Number of moles $=\frac{\text{weight}}{\text{molecular weight}}$

$\frac{P^0-P}{P^0}=\frac{w_B/M_B}{w_A/M_A+w_B/M_B}$

            $\approx \frac{w_B/M_B}{w_A/M_A}$

1. For 10 g of $CH_3COOK$

         $CH_3COOK \rightarrow CH_3COO^- + K^+$

  Ions = 2

It will affect colligative property.

$\frac{P^0-P}{P^0} = \frac{i \times 10/98}{w_A/M_A}$

Relative lowering in vapor pressure will be :

$=\frac{2 \times 10/98}{w_A/M_A}$

$=\frac{0.20}{w_A/M_A}$

2. For 20 g sucrose

Sucrose is non electrolyte, i = 1

$\frac{P^0-P}{P^0} = \frac{ 20/342}{w_A/M_A}$

            $=\frac{0.050}{w_A/M_A}$

3. For 20 g of glucose.

   Glucose is a non electrolyte, i = 1

   $\frac{P^0-P}{P^0} = \frac{20/180}{w_A/M_A}$

               $=\frac{0.11}{w_A/M_A}$

$w_A/M_A$ is same in all three solutions.

Hence, lowering in vapor pressure is maximum in $CH_3COOK$ and minimum is Sucrose.

Vapor pressure from lowest to highest.

10 g of $CH_3COOK$ < 20 g of glucose < 20 g of sucrose
