H2co3 ___> CO2 + H2o

Answer:

H2CO3(aq) ⇆ H2O(l) + CO2(g)

Explanation:

Step 1: Data given

Aqueous carbonic acid = H2CO3

H2CO3 decomposes into CO2 and H2O

Step 2: Balancing the equation

H2CO3(aq) ⇆ H2O(l) + CO2(g)

We do not have to change anything in this reaction since it's already balanced.

We have 2x H on both sides ( 2x in H2CO3 and 2x in H2O)

We have 1x C on both sides (1x in H2CO3 and 1x in CO2)

We have 3x O on both sides (3x in H2CO3 and 1x in H2O, 2x in CO2)

How many decigrams are in 4.6 decagrams?
11111nata11111 [884]

Answer:

\large \boxed{\text{460 dg}}

Explanation:

1. Convert decagrams to grams

\text{Mass} =  \text{4.6 dag} \times\dfrac{\text{10 g}}{\text{1 dag}} = \text{46 g}

2. Convert grams to decigrams

\\text{Mass} =  \text{46 g} \times\dfrac{\text{10 g}}{\text{1 dg}} = \text{460 dg}\\\\\large \boxed{\textbf{4.6 dag = 460 dg}}

Why do covalent bonds form between elements with similar electronegativity?
sesenic [268]

A COVALENT BOND, FORMS BETWEEN ELEMENTS WITH SIMILAR  ELECTRONEGATIVITY AS SHARING OF ELECTRON PAIRS BETWEEN ATOMS IS EASIER AS THEY ARE IDENTICAL.

Explanation:

Bonding atoms with similar electronegativity values form covalent bonds.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.

Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons, also it is the strength an atom has to attract a bonding pair of electrons to itself.

Pure covalent bonds result when two atoms of the same electronegativity bond. This occurs only when two atoms of the same element bond with each other.
