Answer:

the mass of 8.03 mole of NH3 is 136.51 g

Explanation:

The computation of the mass is shown below:

As we know that

Mass = number of moles × molar mass

= 8.03 mol  × 17 g/mol

= 136.51 g

Hence, the mass of 8.03 mole of NH3 is 136.51 g

We simply multiplied the number of moles with the molar mass so that the mass could come

Answer:

Yes

Explanation:

Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.

Explanation:

i agree

Answer:

The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.44moles are there in 17.6g NaOH.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.

Mathematically,

number of moles of NaOH =given mass of NaOH÷ molar mass of NaOH

Molar mass of 1 mole of NaOH= 40 g/mol

mass of NaOH=  17.6g

Substituting all the given values in the above equation, we get

number of moles of NaOH = 17.6g ÷  40 g/mol

number of moles of NaOH  =0.44moles

Therefore, 0.44moles are there in 17.6g NaOH.

Answer: 52Te - Tellurium

Explanation: Radioactivity occurs when an unstable nucleus of an element decompose into a stable element by emitting particles or forms of eletromagnetic energy. There are types of radioactivity and Spontaneous Fission is one of them.

In Spontaneous Fission, the unstable, also called parent, nucleus splits into two smaller nuclei and emitts one or more neutrons.

The reaction spontaneous fission of Cf is represented below.

25498Cf ⇒ 11846Pd + 4n + X

The characteristics of each element of the equation are:

1) The element Cf has atomic mass 254 and atomic number 98.

2) Element Pd has atomic mass 118 and atomic number 46.

3) Neutron is represented as n, has no atomic number and atomic mass 1.

Given these properties, to determine the other nuclide, we have to find out the nuclide's atomic number, as each element in the periodic table has its own atomic number.

At the left side of the equation, atomic number is 98. At the right side, element X's atomic number is

98 - 46 + 0 = 52

In the periodic table, the element with atomic number 52 is Tellurium, whose symbol is Te.

The other nuclide for the spontaneous fission is Tellurium (Te).

Answer:

The atomic number of an atom is the number of protons in the nucleus or the number of electrons in a neutral atom

Human development is defined as expanding people's freedoms and opportunities while also enhancing their well-being. The true freedom that everyday individuals have to choose who they are, what they do, and how to live is what human growth is all about. This discipline tries to comprehend the numerous transformations that people and their relationships go through as they learn and develop.

The youngster reaches puberty during the adolescent stage. A abrupt rise in hormones causes a variety of emotional and mental changes throughout this time. The body's major and secondary sex traits develop during a significant growth spurt phase.

Explanation:

According to standard temperature and pressure and ideal gas equation , the volume of 2 mole of chlorine gas at STP  is 44.8 liters.

Standard temperature and pressure are defined as a standard set of conditions required for experimental measurements which are established to allow comparison between different sets of data.

Standards which are commonly used are those International Union of pure and applied chemistry and national institute of standards and technology.These are not universally accepted standards but are the ones which are commonly used.

Standard conditions of pressure and temperature are necessary to define standard reference conditions used to express volumes of liquids and gases.

These values are important to physicists, chemists ,engineers ,pilots and navigators.On substituting values in ideal gas equation, volume= 2×8.314×273/1=44.8 liters.

Thus, the volume of 2 mole of chlorine gas at STP  is 44.8 liters.
