potassium atom (atomic number 19) and a bromine atom (atomic number 35) can form a chemical bond through a transfer of one electron. The potassium ion that forms has 18 electrons. What best describes the bromide ion that forms? It is a negative ion that has one less valence electron than a neutral bromine atom. It is a positive ion that has one less valence electron than a neutral bromine atom. It is a negative ion that has one more valence electron than a neutral bromine atom. It is a positive ion that has one more valence electron than a neutral bromine atom.

As the result of experimental work, a student finds the density of a liquid to be .137 g/ml. the known density of the liquid is .1478 g/ml. find the student's experimental error (ee) and percentage error (pe).

Answers

the known density of the liquid is

$d_known = 0.1478 g /ml$

the density of a liquid

$d_calculated = 0.137 g /mol$

$experimental error = d_known – d_calculated$

$= 0.1478 – 0.137 = 0.0108 g /mL$

Thus, experimental error of 0.0108 g /mL is present.

$Percentage error = [ (d_known – d_calculated) / (d_known) ] * 100$

$=[ (0.0108) / 0.1478 ] * 100$

$= 7.31 %$

Thus, Percentage error of 7.31 % is present.

B.
The amount of solute dissolved is the maximum amount the solution can hold.
C.
The amount of solute dissolved is more than the usual maximum amount.

Answers

The following definition to the type of solution it describes are

unsaturated solution: A. The amount of solute dissolved is less that the maximum amount the solution can hold.
saturated solution: B. The amount of solute dissolved is the maximum amount the solution can hold.

supersaturated solution: C. The amount of solute dissolved is more than the usual maximum amount.

If a plant needs to make 12.6 g of glucose(c6h1206), how many grams of water are required?

Answers

Answer: 7.6 g of water are required to make 12.6 g of glucose

Explanation:

Moles is calculated by using the formula:

$Moles=\frac{\text{Given mass}}{\text{Molar mass}}$

${\text {moles of glucose}}=(12.6g)/(180g/mol)=0.07moles$

The balanced chemical equation is:

$6CO_2+6H_2O\rightarrow C_6H_(12)O_6+6O_2$

According to stoichiometry:

1 mole of glucose is produced by = 6 moles of water

Thus 0.07 moles of glucose is produced by = $(6)/(1)* 0.07=0.42$ moles of water

Mass of water required = $moles* {\text {Molar mass}}=0.42mol* 18g/mol=7.6g$

Thus 7.6 g of water are required to make 12.6 g of glucose

Predict the products in the following reaction:AgNO3(aq) + Na2CrO4(aq) →

A. AgCrO4(s) + Na2NO3(aq)

B. Ag2CrO4(s) + NaNO3(aq)

C. Ag(CrO4)2(s) + Na2NO3(aq)

D. Ag(CrO4)3(s) + Na(NO3)2(aq)

Answers

I think the correct answer from the choices listed above is option B. The products of the reaction made by silver nitrate and sodium chromate are silver chromate and silver nitrate. The chemical reaction should be written as:

2AgNO3(aq) + Na2CrO4(aq) → Ag2CrO4(s) + 2NaNO3(aq)

The products obtained when 2 AgNO₃ + Na₂CrO₄ reacts is Ag₂CrO₄ + 2 NaNO₃.

What is a Redox Reaction ?

The reaction in which reduction and oxidation takes place simultaneously

by obtaining or losing an electron, the oxidation number of a molecule, atom, or ion varies.

In the question it is given that

AgNO₃(aq) + Na₂CrO₄(aq) → and we have to predict the products

So Silver Nitrate when reacts with Chromic Acid to from silver Chromate and sodium nitrate.

2 AgNO₃ + Na₂CrO₄ → Ag₂CrO₄ + 2 NaNO₃

Therefore Product B is the correct answer.

As ice transforms into steam, A)new molecules are formed. B)the types of atoms are changed. C)energy is absorbed by the molecules. D)the mass of the molecules is increased.

Answers

This is an example of a substance changing state, a physical change, the molecules are changed, but the atoms themselves do not change, just their arrangement, and the mass of the molecules is the same. Therefor energy is absorbed by the molecules, as energy is required to change the state or physicality of a molecule structure.Hope this helps. Let me know if you need additional help!

The answer is C) energy is absorbed by the molecules.
