Cl2 and N2 react according to the following equation 3Cl2(g) + N2(g) rightarrow 2NCl3(g) If 4 L of a stoichiometric mixture of c
melamori03 [73]

Answer:

Volume of NCl3 is 3L

Explanation:

Avogadro states: All gases at the same volume under temperature and pressure constant have the same number of moles.

The chemical equation is:

3Cl2(g) + N2(g) → 2NCl3(g)

Where 3 moles of chlorine reacts with 1 mole of nitrogen to produce 2 moles of NCl3.

But using Avogadros law we can say:

3L of chlorine and 1L of nitrogen produce 2L of Nitrogen trichloride.

3L of chlorine and 1L of nitrogen: 4L (The stoichiometric mixture)

That means, volume of NCl3 produced is 3L

Veronika [31]

Answer:

D. 77.0%

Explanation:

% yield = actual yield/theoretical yield x 100%

% yield = 1.57 g / 2.04 g x 100%

% yield = 76.96 (round up)

Comparing Science and Pseudoscience
Bond [772]

Answer:

The US surgeon general's 1964 report declared that smoking cigarettes was linked to cancer .

The average global temperature of the Earth has increased by almost two degrees in the last century.

Explanation:

Science and pseudoscience differs in terms of scientific methods involved in any study. Science deals with the practices and beliefs that undergo a method of scientific study. Pseudoscience is the term associated with the ideas and beliefs that tend to be scientific in nature but they fail in their execution of following the scientific methods.  

From the given options, two of them are the examples of science and not pseudoscience.

the ability of an ion depends upon its charge density comment on the statement what is essential difference between hydration an
Butoxors [25]
  • The statement that an ability of ion depends on its charge density can be understood by its relation to its definition where charge density refers to the ratio of charge of ions to its volume.
  • The main difference between hydrolysis and hydration is that hydrolysis includes the split of a water molecule whereas hydration does not always include the split of a water molecule.

<u>Explanation</u>:

  • Their relation is that if, greater the charge density greater will be the ability of ion for reaction/reacting.
  • If Sodium ion (Na+) and Magnesium ion (Mg2+). They both contain 10 electrons, i.e. in the ratio (2,8). But, the number( no.) of protons in both ions is different. In the case of ion ( sodium), there are 11 protons present in its nucleus while in the case of ion (magnesium ) there are 12 protons present in its nucleus.
  • A chemical process in which a molecule is separated into two parts by the addition of a molecule of water is known as Hydrolysis. A reaction in which an attachment of hydrogen and hydroxyl ion takes place to a carbon in a carbon double bond is known as Hydration.
