The next step that he has to take is that he must ask a trusted adult whether he can download the game.

<h3>Regulation of minors</h3>

The internet is filled with several contents which may not be suitable fro minors. As such, it is always advisable that minors should use the internet under the strict supervision of an adult.

Even though Javier has heard of the new game and his friends may have downloaded it, the next step that he has to take is that he must ask a trusted adult whether he can download the game.

The sulfur content of an ore is determined gravimetrically by reacting the ore with concentrated nitric acid and potassium chlor

katen-ka-za [31]

Answer:

13.92 %

Explanation:

Mass of $BaSO_4$ = 12.5221 g

Molar mass of $BaSO_4$ = 233.43 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{12.5221\ g}{233.43\ g/mol}$

Moles of $BaSO_4$ = 0.0536 moles

According to the given reaction,

$Ba^{2+}_{(aq)}+SO_4^{2-}_{(aq)}\rightarrow BaSO_4_{(s)}$

1 mole of $BaSO_4$ is formed from 1 mole of $SO_4^{2-}$

Thus,

0.0536 moles of $BaSO_4$ is formed from 0.0536 moles of $SO_4^{2-}$

Moles of $SO_4^{2-}$ = 0.0536 moles

Moles of sulfur in 1 mole $SO_4^{2-}$ = 1 mole

Moles of sulfur in 0.0536 mole $SO_4^{2-}$ = 0.0536 mole

Molar mass of sulfur = 32.065 g/mol

Mass = Moles * Molar mass = 0.0536 * 32.065 g = 1.7187 g

Mass of ore = 12.3430 g

Mass % = $\frac{Mass\ of\ Sulfur}{Mass_{ore}}\times 100$ = $\frac{1.7187}{12.3430}\times 100$ = 13.92 %

Smoking marijuana can be as unhealthy as smoking cigarettes and ___________

Afina-wow [57]

The answer is all of them. But in a school situation, A would be appropriate. This is because the smoke gets into the smokers lungs, whether it be marijuana or tobacco, and can cause cancer cells to grow in your lungs and enter your bloodstream.
So A is the answer.

The compound AlP (aluminum phosphide) is a compound semiconductor having mixed ionic and covalent bonding. Calculate the fractio

netineya [11]

Answer:

0.086

Explanation:

The formula for calculating the fraction of a covalent bond can be expressed as:

= exp (-0.25ΔE²)

$= exp[-0.25(E_{Al}-E_{p})^2]---(1)$

from the equation above;

$E_{Al}$ = the electronegativity of aluminum

$E_P$ = electronegativity of phosphorus

Using the data from periodic table figures;

$E_{Al}$ = 1.5

$E_P$ = 2.1

∴

fraction of the covalent = exp[-0.25(1.5 - 2.1)²]

fraction of the covalent = exp(-0.09)

fraction of the covalent = 0.914

Now, the fraction of ionic bond will be = 1 - the fraction of covalent bond

= 1 - 0.914

∴

the fraction of bond that is ionic = 0.086

Ethylene glycol is a compound used in automotive antifreeze. It is odorless, colorless, and toxic if ingested. Adding ethylene g

const2013 [10]

Answer: Andre. If it is used as an antifreeze, one would infer that it's freezing point is less than water.

Explanation:

The freezing point of ethylene glycol alone (100%) is -12.9oC. That is somewhat less than the freezing point of water but nowhere near the freezing point of water containing 70% ethylene glycol.
