Analysis: The limiting reactant(s) appeared to be
because
Answers
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?
Answers
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 mass in grams of hydrogen is produced by the reaction of 2.0 g of magnesium? (Make sure to balance the reaction first)
Mg(s) + H2O(1) --> Mg(OH)2(s) + H2 (8)
Answers
Answer:
0.164541341 g H2
Explanation:
1) Convert grams to moles by dividing by RMM of Magnesium (24.31g).
2g Mg * (1 mol Mg / 24.31 g Mg) = 0.082270671 mol of Mg
2) Use the balanced equation's ratio of 1 mol Mg: 1 mol H2.
0.082270671 mol of Mg = 0.082270671 mol of H2
3) Convert the mol of H2 back into grams by multiplying by H2's RMM (2 g).
0.082270671 mol of H2 * 2 g H2 = 0.164541341 g H2
* Answer can be rounded to your liking *
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?
Answers
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
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?
Answers
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

A child has a balloon in his house in the air conditioning. He goes outside with the balloon on a hot day. What happens to the temperature of the gas and volume of the balloon?
Answers
Answer:
There would be an increase in temperature and corresponding increase in the volume of the balloon
Explanation:
Charles law is been here
Charles law states that the volume of a given mass of gas is directly proportional to the temperature in Kelvin, provided that the pressure on the gas is kept constant. Mathematically Charles law can be represented thus;
V∝ T
Where V is the volume of the gas and;
T is the temperature.
Relating Charles Law to the question
The child moved outside from the room, constant atmospheric pressure is maintained.The temperature of the room is lower than the temperature outside.From Charles law postulation, there would be an increase in volume because of the increased temperature, since our pressure is same.

Answers
2. Energy. Adding in energy makes the particles of a substance vibrate faster, breaking the forces of attraction between them and removing energy makes the particles vibrate slower and forces of attraction forms between the particles.
3. Gas. The forces of attraction between the particles of a gas are very weak. The particles randomly and quickly move around in all directions.
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.

How many moles of H2 are needed to produce 18 moles NH3 in the reaction below?
N2 + 3 H2 —> 2 NH3
Answers
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
