When would you be most likely to see a rainbow

Rainbows only appear when light passes through water So , it is refracted into its component colors. Rainbows can appear any time there are water droplets in the air and the sunlight shines from behind them at a low angle. That means they are more likely to appear in the early morning or later afternoon

Determine the molarity of a solution prepared by dissolving 141.6 g of citric acid , c3h5o(cooh)3 , in water and then diluting t

gogolik [260]

The molarity of a solution prepared by dissolving 141.6g of citric acid in water is calculated as below

find the the number of moles

moles= mass/molar mass

= 141.6 g/ 192 g/mol = 0.738 moles

molarity= moles/molar mass

= 0.738/3500 x1000 = 0.21 M

It is winter where jenna lives. Its been snowing all day, but now the snow has changed to sleet and then to freezing rain. What

Vladimir79 [104]

Hi!

Answer:

The change in temperature.

Explanation:

Snow forms at 0 °C, when water vapor converts directly into solid ice crystals. Sleet forms when raindrops fall through a layer of air colder than 0 °C. This means that from the time it was snowing to the time it started sleeting the air has gotten warmer but one layer of air stayed cold, hence the formation of sleet. Freezing rain is rain that freezes when it hits a cold surface. This means that from the time it was sleeting to the time there was freezing rain the air had completely warmed and is now above 0 °C but the ground and all other surfaces are still cold.

I hope this helps, as this happens all the time where I live! :)

What is silver?Hows it formed?Who created it?Make sure you include the year.At least 5 sentences for each.

mylen [45]

Silver is A precious shiny grayish-white metal, the chemical element of atomic number 47. Silver is sometimes found in nature in metallic form. It forms a sulfide mineral Ag 2 S called acanthite. Mineral forms of silver include sulfides formed with antimony called Stephanite, miargyrite and pyrargyrite. Silver is a naturally occurring element on the periodic table and can be found in natural deposits throughout the world. As such, it was discovered in 5000 BC, but not invented, by people.

Enter your answer in the provided box. When mixed, solutions of barium chloride, BaCl2, and potassium chromate, K2CrO4, form a y

ira [324]

Answer:

35.42g

Explanation:

Step 1:

The balanced equation for the reaction

BaCl2(aq) + K2CrO4(aq) → BaCrO4(s) + 2KCl(aq)

Step 2:

Determination of the limiting reactant.

It is important to determine which of the reactant is limiting the reaction as the limiting reactant is used to determine the maximum yield of the reaction. The limiting reactant can be determined as follow:

From the balanced equation above,

1 mole of BaCl2 reacted with 1 mole of K2CrO4.

Therefore, 0.7 mole of BaCl2 will also react with 0.7 mol of K2CrO4.

From the above illustration, we can see that it requires a higher amount of K2CrO4 to react with 0.7 mol of BaCl2. This simply means that K2CrO4 is the limiting reactant.

Step 3:

Determination of the number of mole of BaCrO4 produced from the reaction.

The limiting reactant is used in this case.

From the balanced equation above,

1 mole of K2CrO4 produced 1 mole of BaCrO4.

Therefore, 0.14 mole of K2CrO4 will also produce 0.14 mole of BaCrO4.

Step 4:

Converting 0.14 mole of BaCrO4 to grams.

This is illustrated below:

Molar Mass of BaCrO4 = 137 + 52 + (16x4) = 137 + 52 + 64 = 253g/mol

Number of mole BaCrO4 = 0.14 mole

Mass of BaCrO4 =?

Mass = number of mole x molar Mass

Mass of BaCrO4 = 0.14 x 253

Mass of BaCrO4 = 35.42g

Therefore, 35.42g of BaCrO4 is produced from the reaction.
