Zinc phosphide, Zn3P2, is often used as a rat poison. Phosphorus has 5 valence electrons. Assuming that phosphorus is following

the octet rule, how many valence electrons does each zinc atom lose
Chemistry
1 answer:
Nadya [2.5K]3 years ago
4 0

Answer:

Two electrons each!

Explanation:

The question pretty much requires us to find the oxidation number of Zinc in the compound.

Zn3P2

Following oxidation number rules;

O.N of Zn3P2 = 0

.Since phosphorus has valence of 5, it needs three more electrons to achieve its octet state. Hence;

Oxidation number of P = -3

Let oxidation number of Zn = x

We have;

3x  +  2 (-3) = 0

3x + (-6) = 0

3x = 6

x = 6/3 = 2

This means each zn electrons lost 2 electrons.

7.The equation below shows a process that occurs in all green plants.
pychu [463]

Answer:

Ⓓ The process follows the law of conservation of mass and energy is found in the product

Explanation:

This question depicts PHOTOSYNTHESIS, which is the process employed by green plants to manufacture their food in form of sugars (glucose). The general equation, which was given in the question is as follows:

6CO2 + 6H2O + energy → C6H12O6 + 6O2

This chemical reaction follows the LAW OF CONSERVATION OF MASS, which states that the amount of matter in reactant must equate that of the product. In this case, each element contains the same number of atoms in both reactant side and product side.

Also, energy is contained in the product but stored in the chemical bonds of the glucose molecule formed.

What is the empirical formula of a compound containing carbon, hydrogen, and oxygen in the ratio 14:42:84?
Alexxandr [17]
<h3>Answer:</h3>

D. CH₃O₆

<h3>Explanation:</h3>
  • We are given the ratio of carbon, hydrogen and oxygen in a compound as 14: 42 : 84

We are supposed to determine the empirical formula of the compound;

  • We need to know what is an empirical formula;
  • An empirical formula of a compound is a formula that shows the simplest whole number ratio of elements in a compound.

In this case;

The ratio of C : H : O is 14 : 42 : 84

  • Note, this is not the simplest ratio.

But we can simplify further to get the simplest whole number ratio;

  • Therefore, 14 : 42 : 84  is equal to 1 : 3 : 6
  • Thus, the simplest whole number ratio of C : H : O in the compound is 1 : 3 : 6
  • Therefore, the empirical formula of the compound is CH₃O₆

The following equation describes how sodium and chlorine react to produce sodium chloride: 2Na + Cl2 -&gt; 2NaCl Is the equation
DedPeter [7]

Answer:

The equation shows balance.

Explanation:

You can easily count the number of elements on each side.

On the left side of the equation, you have 2 moles of Na and 2 moles of Cl.

On the right side of the equation, you also have 2 moles of Na and 2 moles of Cl because the two elements formed a compound meaning that whatever number is in front of them, both elements will receive the same number.

Atoms or clusters of atoms that are covalently bonded to carbon and influence the behavior of organic compounds are known as
SVEN [57.7K]

Answer:

Functional groups

Explanation:

A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.

There are several functional groups in organic chemistry that determine the properties of organic compounds.

For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.
