if 20.0 ml of 0.10 m ba(no3)2 are added to 50.0 ml of 0.10 m na2co3, will baco3 precipitate?

Answers

Answer 1

When 20.0 ml of 0.10 m Ba(NO₃)₂ (aq) and 50.0 ml of 0.10 m Na₂CO₃ (aq) are mixed together, a precipitate of BaCO₃ will be formed.

In aqueous solution, precipitation is defined as the process of turning a soluble substance into an insoluble solid from a supersaturated solution.

Precipitation of a compound generally occur when its concentration exceeds its solubility. This may happen due to temperature changes, solvent evaporation, or mixing of solvents. Precipitation always occurs faster from a highly oversaturated solution.

When the barium chloride solution reacts with sulfuric acid, a white precipitate of barium sulfate is formed in the product side.

define the term pure substance​

Answers

Answer:

Pure substances are substances that are made up of only one kind of particles and has a fixed or constant structure. Pure substances are further classified as elements and compounds. An element is a substance that consists of only one type or kind of atom

Answer:

define the term pure substance​ :

A pure substance does not have to be of a single element or compound, This can either be one single element or one single compound, but every sample of this substance that you examine must contain exactly the same thing with a fixed, definite set of properties

9. Circle the atom in each pair that has the greater ionization energy.

A) Li or Be
B) Ca or Ba
C) Na or K
D) P or Ar
E) Cl or Si
F) Li or K

Answers

A: BE has more ionization energy than LI

B: CA has more ionization energy than BA.
C: NA has more ionization energy than K

D: AR has more ionization energy than P

E: CI has a more ionization energy than SI
F: LI has more ionization energy than K


If any of these are wrong feel free to correct me in the comments.

A) Be

B) Ca

C) Na

D) Ar

E) Cl

F)  Li

This question simply deals with ionization energy trends across the periodic table or down the group.

Ionization energy is the energy that is needed to remove an electron from its orbital around an atom in such a manner that it will no longer be associated with that same atom.

Now, from studies, it has been found that Ionization energy decreases down a group but it tends to increase as we go from the left to right going across the periodic table.

A) Li(Lithium) and Be(Berrylium) belong to the same period which is period 2 on the periodic table. Berrylium comes after berrylium in that period and as such from the rule earlier, berrylium will have the greater ionization energy.

B) Ca(Calcium) and Ba(Barium) belong to the same group 2 in the periodic table with barium further down the group. Thus, from the trend, Ca(Calcium) will have the greater ionization energy.

C) Na(Sodium) and K(Potassium) belong to the same group 1 in the periodic table with potassium further down the group. Thus, from the trend, Na(Sodium) will have the greater ionization energy.

D) P(Phosphorus) and Ar(Argon) belong to the same period which is period 3 on the periodic table. Argon comes after Phosphorus in that period and as such from the rule earlier, argon will have the greater ionization energy.

E) Cl(Chlorine) and Si(Silicon) belong to the same period which is period 3 on the periodic table. Cl(Chlorine) comes after Si(Silicon) in that period and as such from the rule earlier, Cl(Chlorine) will have the greater ionization energy.

F) Li(Lithium) and K(Potassium) belong to the same group 1 in the periodic table with potassium further down the group. Thus, from the trend,  Li(Lithium) will have the greater ionization energy.

A reaction is first order with respect to reactant A and second order with respect to reactant B. Starting with [A] = 0.175 M and [B] = 0.00250 M, the reaction rate is 2.83 x 10−5 M.S−1. What is the rate constant k? Show your work.

Answers

Answer:

[tex]k=25.9M^{-2}s^{-1}[/tex]

Explanation:

Hello there!

In this case, since rate laws are written by considering the rate constant, concentration and specific orders of reaction of the concentration of the species contributing to the rate of reaction, we write:

[tex]r=k[A][B]^2[/tex]

Since it is first-order with respect to reactant A and second-order with respect to reactant B. In such a way, given the rate and concentrations of both A and B, the involved rate constant k turns out to be:

[tex]k=\frac{r}{[A][B]^2} \\\\k=\frac{2.83x10^{-5}M/s}{(0.175M)(0.00250M)^2}\\\\k=25.9M^{-2}s^{-1}[/tex]

Identify one factor represented in the diagram that is used to classify the ten types of clouds

Answers

Low clouds
Stratus clouds are uniform grayish clouds that often cover the sky. Usually no precipitation falls from stratus clouds, but they may drizzle. When a thick fog “lifts,” the resulting clouds are low stratus. Nimbostratus clouds form a dark gray, “wet” looking cloudy layer associated with continuously falling rain or snow. They often produce light to moderate precipitation.

Middle clouds
Clouds with the prefix “alto” are middle-level clouds that have bases at 6,500 to 23,000 feet up. Altocumulus clouds are made of water droplets and appear as gray, puffy masses, sometimes rolled out in parallel waves or bands. These clouds on a warm, humid summer morning often mean thunderstorms by late afternoon. Altostratus clouds, gray or blue-gray, are made up of ice crystals and water droplets. They usually cover the sky. In thinner areas of them, the sun may be dimly visible as a round disk. Altostratus clouds often form ahead of storms that produce continuous precipitation.

High clouds
Cirrus clouds are thin, wispy clouds blown by high winds into long streamers. They are considered “high clouds,” forming at more than 20,000 feet. They usually move across the sky from west to east and generally mean fair to pleasant weather. Cirrostratus, thin, sheetlike clouds that often cover the sky, are so thin the sun and moon can be seen through them. Cirrocumulus clouds appear as small, rounded white puffs. Small ripples in the cirrocumulus sometimes resemble the scales of a fish, creating what is sometimes called a “mackerel sky.”

Vertical clouds
Cumulus clouds are puffy and can look like floating cotton. The base of each is often flat and may be only 330 feet above ground. The top has rounded towers. When the top resembles a cauliflower head, it is called “cumulus congestus.” These grow upward and if they continue to grow vertically can develop into a giant cumulonimbus, a thunderstorm cloud, with dark bases no more than 1,000 feet above ground and extending to more than 39,000 feet. Tremendous energy is released by condensation of water vapor in a cumulonimbus. Lightning, thunder and violent tornadoes are associated with them.

In the reaction above, how many moles of sodium chloride would be produced
if you started with 20 grams of magnesium chloride and excess sodium
phosphate? The equation is not balanced.
(If anyone can answer in depth if appreciate it )

Answers

Answer:

24.5 g of NaCl

Explanation:

We begin from the balanced reaction:

3MgCl₂ +   2Na₃PO₄  →    6NaCl   +  Mg₃(PO₄)₂

If the sodium phosphate is in excess, then the limting reagent is the magnessium chloride.

We convert mass to moles:

20 g . 1mol / 95.2g = 0.210 moles.

3 moles of MgCl₂ can produce 6 moles of NaCl

0.210 moles of salt, may produce (0.210 . 6) /3 = 0.420 moles

Ratio of reactant is twice the product

We convert the moles to mass:

0.420 mol .  58.45 g/mol = 24.5 g
