Answer:
Hydrogen bonding.
Explanation:
Ammonium lauryl sulfate is also known as ammonium dodecyl sulfate there are two parts in Ammonium lauryl sulfate one is nonpolar hydrocarbon and other part polar sulfate group.
Due to polarity of sulfate group its form hydrogen bond very easily.
It is mainly used as foaming agent the main reason of its use is very much soluble in water and making hydrogen bond with water.
Analysis: The limiting reactant(s) appeared to be
because
there is nothing with which it can react
Explanation:
The limiting reactant(s) prevents a reaction from continuing because there is none left.
Why do limiting reactants occur?Identification of the limiting reactant makes it possible to calculate the theoretical yield of a reaction. The reason there is a limiting reactant is that elements and compounds react according to the mole ratio between them in a balanced chemical equation.
How do you get the limiting reactant?The reactant that is consumed first and limits the amount of product(s) that can be obtained is the limiting reactant. To identify the limiting reactant, calculate the number of moles of each reactant present and compare this ratio to the mole ratio of the reactants in the balanced chemical equation.

how many number of electrons are in aluminium and nitrogen in their free state?
Answer:
MRCORRECT has answered the question
Explanation:
13 electrons
So... for the element of ALUMINUM, you already know that the atomic number tells you the number of electrons. That means there are 13 electrons in a aluminum atom. you can see there are two electrons in shell one, eight in shell two, and three in shell three.
7 electrons
So... for the element of NITROGEN, you already know that the atomic number tells you the number of electrons. That means there are 7 electrons in a nitrogen atom. Looking at the picture, you can see there are two electrons in shell one and five in shell two.

What is the oxidation half-reaction for this unbalanced redox equation? cr2o72– + fe2+ → cr3+ + fe3+ cr3+ → cr2o72– cr2o72– → cr3+ fe3+ → fe2+ fe2+ → fe3+?
Answer:
6Fe^2+(aq) -------> 6Fe^3+(aq) + 6e
Explanation:
The balanced oxidation half equation is;
6Fe^2+(aq) -------> 6Fe^3+(aq) + 6e
A redox reaction is actually an acronym for oxidation-reducation reaction. Since the both reactions are complementary, there can't be oxidation without reduction and there can't be reduction without oxidation.
The main characteristic of redox reactions is that electrons are transferred in the process. The number of electrons transferred is usually deduced from the balanced reaction equation. For this reaction, the balanced overall reaction equation is;
Cr2O7^2–(aq) + 6Fe^2+(aq) +14H^+(aq)→ 2Cr^3+(aq) + 6Fe^3+ (aq) + 7H2O(l)
It is clear from the equation above that six electrons were transferred. Thus six Fe^2+ ions lost one electron each in the oxidation half equation as shown in the balanced oxidation half equation above.

A 0.050L solution of Ba(OH)2 is neutralized by 0.072L of a 0.55 M HNO3 solution. What is the concentration of the Ba(OH)2 solution?
Answer:
0.396M
Explanation:
Step 1:
The balanced equation for the reaction. This is given below:
2HNO3 + Ba(OH)2 —> Ba(NO3)2 + 2H2O
From the balanced equation above,
The mole ratio of the acid (nA) = 2
The mole ratio of the base (nB) = 1
Step 2:
Data obtained from the question. This include the following:
Volume of base (Vb) = 0.05L
Concentration of base (Cb) =..?
Volume of acid (Va) = 0.072L
Concentration of acid = 0.55 M
Step 3:
Determination of the concentration of the base, Ba(OH)2.
The concentration of the base, Ba(OH)2 can be obtained as follow:
Cava /CbVb = nA/nB
0.55 x 0.072 / Cb x 0.05 = 2/1
Cross multiply to express in linear form
Cb x 0.05 x 2 = 0.55 x 0.072
Divide both side by 0.05 x 2
Cb = (0.55 x 0.072) / (0.05 x 2)
Cb = 0.396M
Therefore, the concentration of the base, Ba(OH)2 is 0.396M
The element hydrogen has the highest specific heat of all elements. At room temperature, hydrogen's specific heat is 14.30 J/g •°C. If the temperature of a 340.0 g sample of hydrogen is to be raised by 30°C, how much energy will have to be added to the hydrogen?
Answer:
THE ENERGY NEEDED TO BE ADDED TO RAISE THE TEMPERATURE BY 30°C IS 145, 860 J
Explanation:
The energy needed can be calculated by using the heat formula, which is;
Heat = m c ΔT
m = mass of the hydrogen = 340 g
c = specific heat capacity of hydrogen at room temperature = 14.30 J/g°C
ΔT = change in temperature = 30°C
Heat =?
So therefore,
Heat = 340 * 14.30 * 30
Heat = 145860 J
The energy needed to be added to the hydrogen to bring the mass of 340 g to an increased temperature of 30°C is 145, 860 J or 145.86kJ

In the graph above for the dissociation of a strong acid, why do the bars for H3O+ and A- have the same height as the bar for HA?
Answer:
The concentration of HA is the same as concentration of H3O+ and A- produced.
Explanation:
The dissociation equation is given below:
HA(aq) + H2O (l) —> H3O+(aq) + A-(aq)
From the reaction above, we can see that the acid is monoprotic acid i.e it has only 1 ionisable hydrogen atom.
Now, from the balanced equation, we can see that the acid produced equal concentration of H3O+ and A-.
This account for the reason why the bars for H3O+ and A- have the same height as the bar for HA.

How many moles of H2 are needed to produce 18 moles NH3 in the reaction below?
N2 + 3 H2 —> 2 NH3
Answer:
27 moles of H₂
Explanation:
Equation of reaction:
N₂ + 3H₂ → 2NH₃
From the equation of reaction,
3 moles of H₂ is required to produce 2 moles of NH₃
3 moles H₂ = 2 moles of NH₃
X moles of H₂ = 18 moles of NH₃
X = (3 * 18) / 2
X = 27 moles of H₂
27 moles of H₂ is required to produce 18 moles of NH₃

Solids are the most organized state of matter. States of matter change when energy is added or removed. Gas is the state of matter has the most movement of its particles.
What are the states of matter?The states of matter are the different forms of the matter in which it can exist. They are solids, liquids and gases. Solids are the states of matter in which molecules are very near to each other. They have fixed shape and volume. Liquids is the states of matter in which molecules are a little far from each other. They have different shape and fixed volume. Gas is the states of matter in which molecules are a very far from each other. They have different shape and different volume.
There are two more states of matter which are called as Plasma, Bose Einstein Condensate.
Plasma have highest energy and Bose Einstein Condensate have lowest energy.
Therefore, Solids are the most organized state of matter. States of matter change when energy is added or removed. Gas is the state of matter has the most movement of its particles.

what happens when light is not spread out
Answer:
Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form. Therefore, if you look at photons as waves, spatial gaps never form in light as it travels through free space, no matter how dim it gets.Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form.

Explanation:
How many grams of H20 will be formed when 32.0 g H2 reacts with 16.0 g
O2? *
2H2 + O2 + 2H2O
9.00 g
16.0 g
18.0 g
32.0g
Answer:
18.0 g
Explanation:
M(H2) = 2.0 g/mol
32.0g * 1 mol/2 g= 16 mol H2
M(O2) = 32 g/mol
16.0 g * 1mol/32 g= 0.5 mol O2
2H2 + O2 ---> 2H2O
from reaction 2 mol 1 mol
given 16 mol 0.5 mol
We see that O2 is a limiting reactant.
2H2 + O2 +-------> 2H2O
from reaction 1 mol 2 mol
given 0.5 mol x mol
x =(0.5*2)/1= 1 mol H2O
M(H2O)= 18 g/mol
18 g/mol* 1 mol = 18 g H2O

46g of a mineral contained 16g copper, 14g iron and 16g sulphur. Calculate the empirical
formula of the mineral.
Answer:
CuFeS2
Explanation:
Calculate the moles of each substance by doing moles= mass/relative atomic mass. you should get 0.25 moles of copper and iron and 0.5 moles of sulfur. Then divide all of those numbers by 0.25 (as its the lowest value) you should get 1 for copper and iron and 2 for sulfur. This represents the ratio that they are in within the mineral.
