Given

10 g AgCl

1.00 L of 0.100 M NH3

Required

the amount of diamine silver

Reaction

AgCl + 2 NH₃ → [Ag(NH₃)₂]Cl

mol AgCl :

= mass : MW

= 10 g : 143,32 g/mol

= 0.0698

mol NH₃ :

= M x V

= 0.1 x 1

= 0.1

NH₃ as a limiting reactant

mol [Ag(NH₃)₂]Cl based on NH₃ :

= 1/2 x mol NH₃

= 1/2 x 0.1

= 0.05

Mass diamine silver :

= 0.05 x  177.3822 g/mol

= 8.87 g

Answer:

what????????????????????

Answer:

1. ?

Explanation:

I'm not really sure, but knowing that gas particles are constantly moving makes me think that an ideal gas sample would have constantly moving particles. also with 2., gas has a lot of energy and their particles rarely come into contact with each other (they're even thought of as more independent than as one substance); with 3., there isn't much of a force between gas particles, which is why they're able to stay in that state of matter; and with 4., well, volume is important lol.

But the kinetic molecular theory states that games are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion, so I'm sticking with the answer being number 1.

Answer:

153.3 grams of ZrCl₄ are produced

Explanation:

The equation of the reaction is as follows:

ZrSiO₄ + Cl₂ ----> ZrCl₄ + SiO₂ + O₂

molar mass of ZrSiO₄ = (91 + 32 + 16 * 4) = 187.0 g/mol

molar mass of ZrCl₄ = (91 + 35.5 * 4) = 233.0 g/mol

molar mass of Cl₂ = (35.5 * 2) 71.0 g/mol

From the equation of reaction, 1 mole of ZrSiO₄ reacts with one mole of  Cl₂ to produce one mole of ZrCl₄

number of moles of ZrSiO₄ present in 123 g = 123/187 = 0.65 moles

number of moles of Cl₂ present in 85.0 g = 85.0/71.0 = 1.19 moles

therefore, ZrSiO₄ is the limiting reactant

123.0 g of ZrSiO₄ will react with excess Cl₂ to produce 123 * 233/187 grams of ZrCl₄ = 153.3 grams of ZrCl₄

Therefore, 153.3 grams of ZrCl₄ are produced

Answer:

Potassium (K):   39.10 g/mol

Osmium (Os):   190.23 g/mol

Manganese (Mn):   54.94 g/mol

Explanation:

Just got it right on Edge 2021

The molar mass of the following elements are

Potassium (K): 39.10 g/mol

Osmium (Os): 190.23 g/mol

Manganese (Mn): 54.94 g/mol

The molar mass of a substance is grams of one mole of that substance.

It can be calculated by dividing the atomic weight of the element, and the number of atoms found in that element.

Manganese is a transition metal with the atomic number 25.

Potassium is an essential mineral that is an alkali metal and its atomic number is 19.

Osmium is also a transition metal whose atomic number is 76.

Thus, the molar mass of the elements are, Potassium (K): 39.10 g/mol

Osmium (Os): 190.23 g/mol

Manganese (Mn): 54.94 g/mol

Answer:

1.) Are tightly coiled bundles of DNA

2.) Carry many genes

3.) Are found inside the nucleus of eukaryote

4.) Can be used to diagnose genetic disorders

Explanation:

A chromosome is a thread-like structure made up of DNA. The chromosomes are made of DNA which are tightly coiled around protein.

Chromosomes carry hundreds and thousands of genes. The number of genes in a cell outnumbers the number of chromosomes.

In eukaryotic cells, all the chromosomes are found inside the nucleus of eukaryote.

The chromosomes and DNA can be examined so as to diagnose genetic disorders.

the answer will be 98.4 kJ

As per concept of enthalpy of fusion , 98,397 joules of energy  are required to freeze 10 g of water  at 0°C.

Enthalpy of fusion is defined as the enthalpy change which results from when  a substance changes its state from solid to  a liquid at a constant pressure.Heat of solidification is opposite of enthalpy of fusion.During fusion  there is a phase transition which takes place, from liquid to solid.

The temperature at which the fusion takes place is called as the fusion temperature. This enthalpy is accompanied without any change in temperature.

Enthalpy of fusion  of water=333.55 J/g  . This value is for 1 g of water as per definition,hence for 10 g water enthalpy of fusion is 10×333.55=3335.5 J.

Hence, 3335.5 joules are required for freezing 10 g sample.

its d because a beta particle has a negative charge

In the case when there is the  negatively charged beta particle so the number of nucleons decreased by one.

In terms of chemistry and physics, a nucleon could be treated as the proton or neutron also it considered as the component of the atomic nucleus. Here the no of nucleons in the nucleus should represent the atom mass number.

So based on this, we can conclude that In the case when there is the  negatively charged beta particle so the number of nucleons decreased by one.

Answer:

Option B. The molecules that make up water can more easily slide past one another than the molecules that make up a olive oil.

The molecules that make up water can more easily slide past one another than the molecules that make up olive oil. Hence, option B is correct.

Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow.

Olive oil has a higher viscosity than water because it is a much larger molecule than water with larger dispersion forces.

Hence, option B is correct.

Charles law states that volume of the gas is directly proportional to the temperature i.e.

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

We ave,

V₁ = 300 cm³

T₁ = 40°C = 40 + 273.15 = 313.15  K

T₂ = 110°C = 110 + 273.15 = 383.15 K
