The skeletal equation for the formation of HF from its elements is:

H + F ----> HF

<h3>Skeletal equation</h3>

A skeletal chemical equation is a chemical equation showing the reaction between reactants to form products using the chemical formulae of the reactants and the product.

A skeletal equation is not usually balanced in that the total mass of the elements in the reactant side are not equal to the the mass of the elements in the product side.

<h3>Formation of HF gas </h3>

In the formation of HF gas from its elements, the skeletal equation is shown below:

H + F ----> HF

Therefore, the skeletal equation for the formation of HF is: H + F ----> HF

Wastewater discharged into a stream by a sugar refinery contains 3.40 g of sucrose (C12H22O11) per liter. A government-industry

Ipatiy [6.2K]

<u>Answer:</u> The pressure that must be applied to the apparatus is 0.239 atm

<u>Explanation:</u>

To calculate the osmotic pressure, we use the equation for osmotic pressure, which is:

$\pi=iMRT$

or,

$\pi=i\times \frac{m_{solute}}{M_{solute}\times V_{solution}\text{ (in L)}}}\times RT$

where,

$\pi$ = osmotic pressure of the solution

i = Van't hoff factor = 1 (for non-electrolytes)

$m_{solute}$ = mass of sucrose = 3.40 g

$M_{solute}$ = molar mass of sucrose = 342.3 g/mol

$V_{solution}$ = Volume of solution = 1 L

R = Gas constant = $0.0821\text{ L atm }mol^{-1}K^{-1}$

T = temperature of the solution = $20^oC=[20+273]K=293K$

Putting values in above equation, we get:

$\pi =1\times \frac{3.40g}{342.3g/mol\times 1}\times 0.0821\text{ L. atm }mol^{-1}K^{-1}\times 293K\\\\\pi =0.239atm$

Hence, the pressure that must be applied to the apparatus is 0.239 atm

What formula can be used to calculate [H30+]

Yuliya22 [10]

[H3O+] is just the same with [H+]. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14

What is the length of the hypotenuse of the right triangle ABC in the figure?

Lostsunrise [7]

Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse.
The triangles are similar (right triangles which share an angle (A), so...
AD/AC = AC/AB 5/6 = 6/AB AB = 6*6/5 = 36/5 = 7.2

What causes pressure inside an inflated soccer ball?

ioda

Answer:

Explanation:

Ball bounces because of the difference in the air pressure on the outside of the ball, and opposite the point of impact, and the pressure inside of the ball. This means that the inside of the ball now has less space to contain the air molecules contained inside the ball, increasing the pressure inside the ball.
