Cu + 2AgNO3 es002-1.jpg 2Ag + Cu(NO3)2 How many moles of copper must react to form 0.854 mol Ag?

1 answer:

4 0

Balance Chemical Equation is as follow,

<span> Cu + 2 AgNO</span>₃ → 2 Ag + Cu(NO₃)₂

According to Balance Equation,

2 Moles of Ag is produced by reacting = 1 Mole of Cu
So,
0.854 Moles of Ag will be produced by reacting = X Moles of Cu

Solving for X,
X = (0.854 mol × 1 mol) ÷ 2 mol

X = 0.427 Moles of Cu
Result:
0.854 Moles of Ag are produced by reacting 0.427 Moles of Cu.

Discuss some of the biotic (living) and abiotic (nonliving) factors in the chimps’ ecosystem that affect their behavior.

Genrish500 [490]

Answer:

Diet: fruit, leaves, bark, stems, seeds, eggs, insects, birds, small to medium sized primates - red tail monkeys, yellow baboons, bushbuck and warthogs.

Environmental Relationship - The chimpanzee keeps the plants it eats short, moves dirt around which helps things living in the dirt, keeps bird and small monkey populations that it eats from overpopulating.

Different biotic and abiotic factors affect why the chimps live where they do. (Spatial Relationships)

You have 49.8 g of O2 gas in a container with twice the volume as one with CO2 gas. The pressure and temperature of both contain

IrinaVladis [17]

Answer:

34.2 g is the mass of carbon dioxide gas one have in the container.

Explanation:

Moles of $O_2$ :-

Mass = 49.8 g

Molar mass of oxygen gas = 32 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{49.8\ g}{32\ g/mol}$

$Moles_{O_2}= 1.55625\ mol$

Since pressure and volume are constant, we can use the Avogadro's law as:-

$\frac {V_1}{n_1}=\frac {V_2}{n_2}$

Given ,

V₂ is twice the volume of V₁

V₂ = 2V₁

n₁ = ?

n₂ = 1.55625 mol

Using above equation as:

$\frac {V_1}{n_1}=\frac {V_2}{n_2}$

$\frac {V_1}{n_1}=\frac {2\times V_1}{1.55625}$

n₁ = 0.778125 moles

Moles of carbon dioxide = 0.778125 moles

Molar mass of $CO_2$ = 44.0 g/mol

Mass of $CO_2$ = Moles × Molar mass = 0.778125 × 44.0 g = 34.2 g

<u>34.2 g is the mass of carbon dioxide gas one have in the container.</u>

Which of the following statements is not true of the combustion of an organic compound?

Novay_Z [31]

<em>The following statements are not true of the combustion of an organic compound is </em>

<em>C. it can also be described as a synthesis reaction </em>

<h3><em>Further explanation</em></h3>

Organic compounds have a characteristic that there is a chain of carbon atoms, while in inorganic does not have a chain of carbon atoms

The reaction of a substance with oxygen is called a combustion reaction

Perfect combustion of carbon compounds will get CO2 gas, whereas if it is not perfect it will produce CO gas

Identification of carbon compounds can usually be done by flowing it into lime water which produces turbid water because of the reaction of CO2 with Ca(OH)₂ to form CaCO₃

Burning organic samples will convert C atoms to CO₂ and H to H₂O

We see the answer choices

1. Oxygen is included in the reactants in the combustion process

So the answer is correct

2. Energy is released during combustion because the reaction is exothermic or releases heat with a negative enthalpy of combustion

So the answer is correct

3. A decomposition reaction is the decomposition reaction of a compound into its constituent elements. In combustion reactions, occur decomposition, not a formation reaction

So the answer is wrong

4. CO₂ is the result of combustion,

So the answer is correct

An object accelerates 3.0 m/s2 when a force of 6.0 Newton’s is applied to it. What is the mass of the object?

Alekssandra [29.7K]

Answer:2kg

Explanation:

Mass =?

Acceleration = 3.0 m/s2

Force = 6.0N

Force = Mass x Acceleration

6 = Mass x 3

Mass =6/3 = 2Kg
