It’s a chemical reaction I guess? Or maybe it hits the water and unlike a solid and it being a liquid it goes into the water causing it to spread or something like that.

Electricity can flow through water (so don't swim with a toaster plugged in or at all)

Are nuclear bombs ethical? Explain please
Mrac [35]

Answer:

<u>Yes, they are.</u>

Explanation:

The United States is one of these nuclear superpowers, making the ethical issues associated with these weapons critical and relevant. ... Most research across disciplines unanimously agrees that it is immoral to detonate an atomic weapon due to both short and long-term catastrophic effects.

In fact, some scholars have concluded that it is therefore morally wrong to act in ways that produce these outcomes, which means it is morally wrong to engage in nuclear warfare.

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

When you look at a chocolate chip cookie, which is older-- the cookie or the chocolate chip?explain.
storchak [24]
The chocolate? Im guessing its chocolate bc the cookie part was made and then they add the chocolate chips which who knows where actually made. U have to mix different ingredients to make the “cookie” part so thats the “youngest” sort of speak
