Sodium chloride can be produced by the reaction of sodium metal with chlorine gas. Which is the limiting reactant if 6.70 moles
Alecsey [184]

Answer:

Chlorine gas.

Explanation:

Hello!

In this case, the undergoing chemical reaction is:

2Na+Cl_2\rightarrow 2NaCl

Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:

n_{NaCl}^{by\ Na}=6.70molNa*\frac{2molNaCl}{2molNa}=6.70molNaCl \\\\n_{NaCl}^{by\ Cl_2}=3.20molCl_2*\frac{2molNaCl}{1molCl_2}=6.40molNaCl

Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.

Best regards!

1 Mothers ages 8 years more than twice her daughter's
Anit [1.1K]
<h3>♫ :::::::::::::::::::::::::::::: // Hello There ! //  :::::::::::::::::::::::::::::: ♫</h3>

➷  We can use the information to form an equation, which we can solve later

M = 2x + 8

Simply substitute the daughter's age into x:

M = 2(56) + 8

Now solve:

M = 120

What is the balanced, net ionic equation
Effectus [21]

A net ionic equation which tends to show the ions that underwent a change in the reaction

<h3>What is a reaction equation?</h3>

The term reaction equation is the term that can be used to describe the instance where reactants combine together. If this occurs in solution we can say that the reaction is an aqueous phase reaction because the reactants wee all dissolved in solution.

It is possible for ionic substances in solution to react. When this occurs, it is possible for us to put down a net ionic equation which tends to show the ions that underwent a change in the reaction and the product of this reaction may be a liquid, a gas or a solid.

In this case, the complete molecular equation can be written as;

Ba(NO3)2(aq) + Na2SO4(aq) -----> BaSO4(s) + 2NaNO3(aq)

The complete ionic equation can be written as;

Ba^2+(aq) + 2NO3^-(aq) + 2Na^+(aq) + SO4^2-aq)  -----> BaSO4(s) +  2NO3^-(aq) + 2Na^+(aq)

Net ionic equation is;

Ba^2+(aq) + + SO4^2-aq)  -----> BaSO4(s)

You have cyclohexene, water, cyclohexanol, and a little sulfuric acid catalyst in a test tube at 60 oC and everything is at equi
Anvisha [2.4K]

Answer:

See explanation

Explanation:

We can convert cyclohexanol to cyclohexene in the presence of a strong acid such as sulfuric acid catalyst in a test tube at 60 oC by heating up the mixture to about 80 oC. This is a dehydration reaction so water is removed  to yield the alkene. A drying agent is used to remove any trace amount of water left in the system. This overall reaction is endothermic.

Also, the reverse is the case when we want to carry out the hydration of cyclohexene to yield cyclohexanol. The overall reaction is exothermic and involves the addition of more water to the alkene and then cooling down the system to about 40 oC.
