Explanation:

Although all puppies are officially considered adult dogs once they reach one year old, puppies continue to grow in height and size while their bones are still developing, which takes anywhere from 6 to 24 months. Their skeletal growth is what determines how tall they will become as adults.

Answer:

sugar and salt, as they can dissolve in water. Sugar and salt have a high solubility in water. So, sugar and salt can form a solution with water.

Explanation:

Answer:

Sodium is placed in group 1 of the periodic table of Alkali metals, and has a valence shell with one electron, making them very reactive. When placed in water, it disperses heat and begins to ignite and burn (due to its very reactive nature), resulting compound is hydrogen gas (H2), and a very strong base (Sodium Hydroxide, NaOH) used for cleaning appliances and for neutralizing agents.

Silver is placed on the transitional metal section of the periodic table, not quite reactive but is the most conductible element on the planet, is malleable and ductile. Due to it being costly and its rarity, it's not relied on for computer parts or wires. Silver doesn't actually directly react with water in its liquid state. It does produce hydrogen gas and Silver Oxide when reacting with water vapour.

In short, Sodium and water create new products, while Silver and water (only in water's gaseous form) form different products.

It would take 211 hours to plate 28.3 g of silver on a flute.

The equation of the reaction;

Ag^+(aq) + e -----> Ag(s)

We know that 1 F of electricity is required to deposit 107.87 g of Ag. Also 1F = 96500 C

Now;

Since  107.87 g is deposited by 96500 C of electricity

28.3 g is deposited by  28.3 g ×  96500 C/ 107.87 g

= 25317 C

Also;

Q = It

I = current

t = time

25317 C =  2.0 amps × t

t = 25317 C /2.0 amps

t = 12658.5 seconds or 211 hours

Answer:

Explanation:

Electrolysis equation is:

[tex]Ag1+ + 1e- ------> Ag[/tex]

1 mol of Ag requires 1 mol of electron

1 mol of electron = 96485 C

So,

1 mol of Ag requires 96485 C

let us calculate mol of element deposited:

molar mass of Ag = [tex]107.87 g/mol[/tex]

number of mol of Ag, [tex]n = \frac{mass of Ag}{molar mass of Ag}[/tex]

[tex]n = \frac{28.3}{107.87}\\\\n = 0.2623 mol[/tex]

[tex]total charge = mol of element deposited * charge required for 1 mol\\\\total charge = 0.2623*9.649*10^4\\\\total charge = 2.531*10^4 C[/tex]

Therefore,

[tex]time = \frac{Q}{i}\\\\= \frac{2.531*10^4}{2}\\\\= 1.265*10^4 seconds\\\\= 3.515 hr[/tex]

Answer:

b) (i): 0.91 Amgstroms

(ii): 9.1 × 10^-11 Angstroms

(c): Volume = 20 Angstroms

it's 3 dollars per 12 eggs so 3/12

simplify 3/12 by dividing both numbers by 3 so you get 1/4

you should know what 1/4 of a dollar is

or think of it this way 12 eggs are 3 dollars so every 4 eggs is one dollar. divide 1 dollar by 4 eggs

Answer:

Because it only needs one more electron to get to a full valence shell (8), so it really wants it and is pulling other electrons in. It also has to do with needing one more electron to fill the 2p shell. It is a small element which means its electrons are pulled tightly to the nucleus.

The mass of a 0.513 mol of Al2O3 is 52.33g.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the molar mass of the substance by its number of moles. That is;

mass of Al2O3 = no. of moles of Al2O3 × molar mass of Al2O3

According to this question, there are 0.513 moles of Al2O3.

Mass of Al2O3 = 0.513 × 102

Mass of Al2O3 = 52.33g

Therefore, the mass of a 0.513 mol of Al2O3 is 52.33g.

Answer:

The molecular structure affects solubility mainly biased on its polarity or bonded ions.

Explanation:

Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.

**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.

I don't know if it's correct but based on the question that was the only way I saw how to work it out

Answer:

34.9103 or 34.9 g

Explanation:

Remember Density is a broken heart: m/v.

In this scenario (Let x = # of grams in the sample of gasoline),

D = 0.7198 g/mL = x g / 48.5 mL

So,

(0.7198 g/mL) * (48.5 mL) = x g

x g = 34.9103 = 34.9 g (Accounting for Significant Figures)
