Sleet is a type of precipitation that is formed by water and snow that is usually partially molten.

Sleet consists of icy raindrops that hit the surface, that is, part of the precipitation is frozen and the other forms water droplets.

Therefore, we can conclude that sleet is a form of winter precipitation, in which rain and snow occur at the same time.

Answer:

Alright the very first thing you need to do is balance the equation:

2HCl + Na2CO3 -----> 2NaCl + CO2 + H2O

Now we need to find the limiting reactant by converting the volume to moles of both HCl and Na2CO3.

Volume x Concentration/molarity = moles

0.235L x 0.6 M = 0.141 moles / molar ratio of 2 = 0.0705 moles of HCl

0.094L x 0.75 M = 0.0705 moles /molar ratio of 1  = 0.0705 moles of Na2CO3

Since both of the moles are equal, it means the entire reaction is complete (while the identification of limiting reactant may seem like an unnecessary step, it's quite essential in stoichiometry, so keep an eye out) and there is no excess of any reactant.

Now we know that the product we want to calculate is aqueous so, following the law of conservation of mass, we should add both volumes together to calculate how much volume we could get for NaCl.

0.235 + 0.094 = 0.329L of NaCl

Now we apply the C1V1 = C2V2 equation using the concentration and volume of Na2CO3 because it's molar ratio is one to one to NaCl (You can also use HCL, but you have to divide their moles by 2 for the molar ratio)  and the volume we just calculated for NaCl.

(0.75M) x (0.094L) = C2 x (0.329L)

Rearrange equation to solve for C2:

(0.75M) x (0.094L)  =  C2

    (0.329L)

C2 = 0.214 M (Rounded)

When the reaction is finished, the NaCl solution will have a molarity concentration of 0.214 M.

The mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

The reaction between carbon and pxygen atom is exprssed as:

Mass of CO2 = number of moles * molar mass

Mass of CO2 = 0.29 * (12 + 32)

Mass of CO2 = 0.29 * 44

Mass of CO2 = 12.76grams

Hence the mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

This problem is providing the basic dissociation constant of ibuprofen (IB) as 5.20, its pH as 8.20 and is requiring the equilibrium concentration of the aforementioned drug by giving the chemical equation at equilibrium it takes place. The obtained result turned out to be D) 4.0 × 10−7 M, according to the following work:

First of all, we set up an equilibrium expression for the given chemical equation at equilibrium, in which water is omitted for it is liquid and just aqueous species are allowed to be included:

[tex]Kb=\frac{[IBH^+][OH^-]}{[IB]}[/tex]

Next, we calculate the concentration of hydroxide ions and the Kb due to the fact that both the pH and pKb were given:

[tex]pOH=14-8.20=5.80[/tex]

[tex][OH^-]=10^{-5.8}=1.585x10^{-6}M[/tex]

[tex]Kb=10^{-5.20}=6.31x10^{-6}[/tex]

Then, since the concentration of these ions equal that of the conjugated acid of the ibuprofen (IBH⁺), we can plug in these and the Kb to obtain:

[tex]6.31x10^{-6}=\frac{(1.585x10^{-6})(1.585x10^{-6})}{[IB]}[/tex]

Finally, we solve for the equilibrium concentration of ibuprofen:

[tex][IB]=\frac{(1.585x10^{-6})(1.585x10^{-6})}{6.31x10^{-6}}=4.0x10^{-7}[/tex]

He atoms are smaller than Ne atoms (4AMU vs 20AMU).  Although the kinetic energy and concentrations are the same (same temperature and each have 0.5 mole  in 10.0L containers), the kinetic energy is a product of mass and velocity.  Since the Ne mass is greater, it will have a lower speed, thus taking longer to bounce out the pinhole.

Answer:

We know that 1 mole equals to 6.02 x 10^23 atoms (which is Avogadro's number), so to get to atoms from moles, you would divide the atoms of gold by Avogadro's number

(1.93 x 10^24) / (6.02 x 10^23)

= 3.2 mol of gold (rounded)

It measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 3.21 moles of gold are in 1.93 x 10²⁴atoms of gold.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. Mole is directly proportional to the given number of atoms.

Given number of atoms of gold= 1.93 x 10²⁴atoms

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mole of gold =given number of atoms of gold ÷ 6.022×10²³(Avogadro number)

Substituting all the given values, we get

Mole of gold = 1.93 x 10²⁴atoms ÷ 6.022×10²³(Avogadro number)

Moles of gold=3.21 moles of gold

Therefore, 3.21 moles of gold are in 1.93 x 10²⁴atoms of gold.

Explanation:

from left to right the nuclear effective charge is increasing, attracting with a greater force the electrons and making the atom to reduces itd atomic radius

The atomic radius decreases along a period in periodic table.  Thus, from the third element Li to the 9th element fluorine, atomic radius decreases and F has the lowest radius among them.

Atomic radius is the distance from the  nucleus to the valence shell. The atomic radius decreases from left to right in periodic table. Thus, the higher atomic radius is exhibited by metallic elements.

The horizontal rows in the periodic table is called periods. Along a period , atomic radius decreases and electronegativity increases. When moving to the right there is no increase in the number of shells and the filling of electrons does not achieve octet except for group 18. Hence, they are electronegative.

From atomic number 3 to 9 atomic number is decreasing. Hence, among these elements, the smallest one is fluorine (Z = 9).
