<u>Answer:</u> The coefficient of NOCl in the given balanced chemical equation is 1

<u>Explanation:</u>

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

Every balanced chemical equation follows law of conservation of mass

For the given balanced chemical equation:

$NO(g)+\frac{1}{2}Cl_2(g)\rightarrow NOCl(g)$

By Stroichiometry of the reaction:

1 mole of nitrogen monoxide gas reacts with $\frac{1}{2}$ moles of chlorine gas to produce 1 mole of NOCl

Hence, the coefficient of NOCl in the given balanced chemical equation is 1

Answer:

1

Explanation:

The numbers in front of the formulas (the coefficients) tell you how many moles of a substance are involved in a reaction.

If no coefficient is shown, we assume it is 1.

NOCl has no coefficient, so 1 mol of NOCl is in the balanced equation.

A large balloon contains 233 L of neon at 22.0C and 760. Torr. If the balloon ascends to an altitude where the temperature is -

shepuryov [24]

Answer: The volume in the balloon at the higher altitude is 260 L

Explanation:

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 760 torr

$P_2$ = final pressure of gas = 511 torr

$V_1$ = initial volume of gas = 233 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $22.0^0C=(22.0+273)K=295K$

$T_2$ = final temperature of gas = $-52.0^0C=(-52.0+273)K=221K$

Now put all the given values in the above equation, we get:

$\frac{760\times 233}{295}=\frac{511\times V_2}{221}$

$V_2=260L$

The volume in the balloon at the higher altitude is 260 L

Non-electrolyte = A, 10.6 grams, dissolved in solvent B, 740 grams, the boiling point of the solution is higher than the boiling

Thepotemich [5.8K]

Answer:

2.1 °C/m

Explanation:

Hello, for this exercise, consider the formula:

$T_{solution}-T{solvent}=K_bm_solute$

Considering that the difference in the temperature is 0.284°C, and the given molality by:

$m_{solute}=\frac{10.6g\frac{1mol}{106g}}{740g*\frac{1kg}{1000g} } \\m_{solute}=0.135m$

Now, solving for $K_b$ , we get:

$K_b=\frac{0.284C}{0.135m}\\K_b=2.1 C/m$

Best regards.

If 100.0g of nitrogen is reacted with 100.0g of hydrogen, what is the excess reactant? What is the limiting reactant? Show your

Drupady [299]

N₂ : limiting reactant

H₂ : excess reactant

<h3>Further explanation</h3>

Given

mass of N₂ = 100 g

mass of H₂ = 100 g

Required

Limiting reactant

Excess reactant

Solution

Reaction

<em>N₂+3H₂⇒2NH₃</em>

mol N₂(MW=28 g/mol) :

$\tt mol=\dfrac{mass}{MW}=\dfrac{100}{28}=3.571$

mol H₂(MW= 2 g/mol) :

$\tt mol=\dfrac{100}{2}=50$

A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactans become a limiting reactants

From the equation, mol ratio N₂ : H₂ = 1 : 3, so :

$\tt \dfrac{3.571}{1}\div \dfrac{50}{3}=3.571\div 16.6$

N₂ becomes a limiting reactant (smaller ratio) and H₂ is the excess reactant

Do you think you could go a week

Alinara [238K]

Answer:

The answer to your question is No

Explanation:

I think it is impossible to go a week without causing any chemical reaction. For example, if a drive my car or motorcycle, I am burning fuel and that is a combustion reaction.

Also, I want to cook, all this process involves a lot of chemical reactions among the components of food and maybe water.

If I take a shower or wash my hands, between the soap and the microbes occur are some chemical reactions that help to remove these organisms.

Also, when I wash my clothes something similar happens.

These are some examples of the chemical reactions that happen daily but I think there are a lot more.
