Write a BALANCED chemical equation for the acid base reaction between aqueous perchloric acid and aqueous calcium hydroxide.​

Answers

Answer 1

Answer:

2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O

Explanation:

Formula for aqueous perchloric acid is; HClO_4 (aq)

Formula for aqueous calcium hydroxide is; Ca(OH)_2 (aq)

Thus chemical equation is;

HClO4 + Ca(OH)2 = Ca(ClO4)2 + H2O

We have to balance it and so we now have;

2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O

what kind of bonds involve a transfer of electrons? what kind of bond involves sharing of electrons?

Answers

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Answer:

While covalent bonding involves sharing electrons between two atoms, ionic bonding involves the complete transfer of electrons from one atom to another, creating positive and negative ions. These ions are then held together by the attraction between their opposite charges.

ions

freons
xenons
phlogistons

Answers

Answer:

ions

Explanation:

Individual atoms of the same element but having slightly different number of protons and electrons are called ions.

Ion is a charged particle.

An atom is made up of three fundamental subatomic particles. Protons are the positively charged particles Electrons are the negatively charged particles Neutrons do not carry any charges.

When the number of protons > electrons the body is positively charged.

When the number of electrons > protons the body is negatively charged.

Charged particles are called ions.

How many liters of ammonia are formed with 49.8 g of nitrogen gas reacting with 10.7 g of hydrogen gas at S.T.P.?

Answers

the reaction is as follows:

N2+3H2---->2NH3

the number of moles of N2 is 49.8g/14gmol^-1=3.56mol

the number of moles of H2 is 10.7g/2gmol^-1=5.35mol

here, since the ratio of N2/H2 is 1/3, we can see that H2 is the limiting reagent. therefore, the reaction proceeds as follows:

N2 + 3H2 ---------------> 2NH3
5.36mol (2/3)(5.36mol)=3.57mol

therefore, the number of moles of ammonia formed is 3.57mol. at STP, P=1atm, T=273K.
Therefore, V(NH3)=(3.57)(22.38)=79.822 L

Answer:

C. they carry energy

Explanation:

Energy can be carried from one place to another by waves, including water, light, and sound waves. Waves are oscillating disturbances that travel through but do not move matter.

Infrared radiation escaping from hot coals is an example of invisible waves carrying energy. This energy can be felt as heat.

How many moles are there in a 122 gram sample of nickel (Ni)?
7.16 x 103 moles
6.22 mol
2.08 mol
0.481 mol

Answers

the molecular weight of nickel is 58.69 g/mol. thus in a 122 gram sample of nickel there are 122/58.69=2.08 moles of nickel.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

Nickel:

The atomic number of nickel is 28.The symbol of nickel is Ni.Density of a nickel 8.908 g/cm3.It is a d block element.It belongs to group 10 and period 4.It is also called transition metal.It is a metal and is located between groups 2 and 3.

Mass of nickel given: 122 grams.

Atomic mass of nickel: 58.71 g mol

Number of moles = Mass / molar mass

                             = 122/ 58.71

                              = 2.078

                              = 2.08 moles.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

Answers

Answer:

CH4 + 2O2 → CO2 + 2H2O

Explanation:

This is all i could come up with im sorry.

The amount of water formed in the given chemical reaction is 9 grams.

What is Stoichiometry?

Stoichiometry is the calculation for the determination of the relative amount of reactants and products in chemical reactions. Stoichiometry is based on the law of conservation of mass where the total mass of the reactants in reaction equals the total mass of the products.

If the quantity of one reactant is known and the quantity of the product can be determined empirically, then the quantity of the other reactants can be calculated.

Given chemical equation is:

CH₄  +   2O₂  [tex]\longrightarrow[/tex]   CO₂   +   2H₂O

16g        32g         44g           32g        (from their molecular masses)

The amount of methane, oxygen, and carbon dioxide is 4g, 16g, and 32 g respectively.

16g of methane react with oxygen = 32g

4g of  methane will react with oxygen = 8g

It means here methane is the limiting reagent as the given amount of oxygen is more than reacted one.  So CH₄ will decide the amount of water.

16g of methane produces water = 32g

Then 4g of methane will produce water = (32/16) × 4 = 9 g

Therefore, 9 grams of water should be formed in this reaction.

Answers

Answer:

2Ag^+(aq) + 2Cl^-(aq) --------> 2AgCl(s)

Explanation:

The net ionic equation reflects the main reaction that occurred in the system. It tells you the most important reaction that took place.

If we first put down the balanced molecular equation for the reaction, we have;

CaCl2(aq) + 2 AgC2H3O2(aq) ---------> 2 AgCl(s) + Ca(C2H3O2)2 (aq)

The net ionic equation is;

2Ag^+(aq) + 2Cl^-(aq) --------> 2AgCl(s)

What type of radioactive decay is shown? 82 Br → 82 Kr + te 35 36 Alpha O Beta O Gamma?​

Answers

Answer:

In 1889, Ernest Rutherford recognized and named two modes of radioactive decay, showing the occurrence of both processes in a decaying sample of natural uranium and its daughters. Rutherford named these types of radiation based on their penetrating power: heavier alpha and lighter beta radiation. Gamma rays, a third type of radiation, were discovered by P. Villard in 1900 but weren't recognized as electromagnetic radiation until 1914. Since gamma radiation is only the discharge of a high-energy photon from an over-excited nucleus, it does not change the identity of the atom from which it originates and therefore will not be discussed in depth here.

Because nuclear reactions involve the breaking of very powerful intra nuclear bonds, massive amounts of energy can be released. At such high energy levels, the matter can be converted directly to energy according to Einstein's famous Mass-Energy relationship E = mc2. The sum of mass and energy are conserved in nuclear decay. The free energy of any spontaneous reaction must be negative according to thermodynamics (ΔG < 0), and ΔG is essentially equal to the energy change ΔE of nuclear reactions because ΔE is so massive.
