Chemistry
1 answer:
Leto [7]3 years ago
6 0

Answer : The correct option is, (D) double replacement reaction

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

X+Y\rightarrow XY

Decomposition reaction : A chemical reaction in which larger reactant decomposes to give two or more than two products.

It is represented as,

AB\rightarrow A+B

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

A+BC\rightarrow AC+B

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

XY+AB\rightarrow XB+AY

(X and A are the cations, Y and B are the anions)

The given reaction is:

2NaCl(aq)+CuSO_4(aq)\rightarrow Na_2SO_4(aq)_CuCl_2(aq)

This reaction is a double displacement reaction.

Explain your answer.
Lilit [14]

Answer:

14. (C) -3; 16. B. 0, 3

Explanation:

14. Ionic charge

X: ns²np³.

The element is three electrons short of having a complete octet.

It is likely to react chemically to add those three electrons and form an X³⁻ ion.

16. Orbitals in subshells

The n = 1 shell contains no p orbitals. All the other shells contain three p orbitals.

The n = 1 shell contains only one s orbital. Every higher shell contains a p subshell, and each p subshell contains three p orbitals.

Find the density of a cube on Earth that weighs 1.5 kg and has a side-length of 10 cm.
tamaranim1 [39]

Answer:

1500kg/m^3

Explanation:

Formula:

d=m/v

Given:

m=1.5kg

v=1000cm^3

(The side length of a cube is always equal to the others)

Required:

d=?

Solution:

d=m/v

d=1.5kg/1000cm^3

d=1.5kg/0.001m^3

d=1500kg/m^3

Hope this helps ;) ❤❤❤

What reaction would the chemical equation 2H2O→2H2+O2 represent?
Leto [7]

Answer:

decomposition of water

Explanation:

The reaction will represent the decomposition of water. It usually carried by an electrolytic process in the laboratory.

  • Water molecule is broken down into its constituent hydrogen gas and oxygen gas components.
  • The breaking down of one compound to give other compounds is decomposition.
  • This is not a replacement reaction.
  • In decomposition, we often start with a single reactant and results in one or more products.

Which molecule does not contain hydrogen bonding intermolecular attractive forces?
Delicious77 [7]

Hydrogen bonding occurs between polar molecules that have a hydrogen atom that is directly bonded to a nitrogen, an oxygen, or a fluorine atom. That creates an extremely polar molecule with a permanent net dipole moment.

A hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative "donor" atom or group, and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac). Such an interacting system is generally denoted Dn–H···Ac, where the solid line denotes a polar covalent bond, and the dotted or dashed line indicates the hydrogen bond.The most frequent donor and acceptor atoms are the second-row elements nitrogen (N), oxygen (O), and fluorine (F).
