What Type of Reaction is the following: lithium carbonate → lithium oxide + carbon dioxide

Chemistry
1 answer:
valentinak56 [21]4 years ago
5 0

Answer: 2. Decomposition

Explanation:

Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.

Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.

lithium carbonate → lithium oxide + carbon dioxide

LiCO_3\rightarrow LiO+CO_2

Single replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

A double replacement reaction is one in which exchange of ions take place.

Most nonmetals form covalent or ionic bonds, depending on the element with which they react. Carbon predominantly forms covalent

A)Calcium-This because calcium has two valence electrons hence it is a metal therefore it will form an ionic bond with carbon.

Determine the mass of 5.2 x 10 power of 21 molecules of propanol C3H7OH(l), on grams.
Alja [10]

n(\text{C}_3\text{H}_7\text{OH}) = N(\text{C}_3\text{H}_7\text{OH}) / N_A\\ \phantom{n(\text{C}_3\text{H}_7\text{OH})} = 5.2 \times 10^{21} / (6.02 \times 10^{23})\\ \phantom{n(\text{C}_3\text{H}_7\text{OH})} = 8.6 \times 10^{-3} \; \text{mol}

where N_A = 6.02 \times 10^{23}\; \text{mol}^{-1} the Avogadro's constant that relates the number of particles to their number, in the unit moles \text{mol}.

The molar mass of propanol- mass per mole propanol- can be directly deduced from its molecular formula with reference to a modern periodic table.

M(\text{C}_3\text{H}_7\text{OH}) = \underbrace{3 \times 12.01}_{\text{carbon}} + \underbrace{8 \times 1.008}_{\text{hydrogen}} + \underbrace{1\times 16.00}_{\text{oxygen}} = 60.09 \; \text{g} \cdot \text{mol}^{-1}

8.6 \times 10^{-3} \; \text{mol} of propanol molecules would thus have a mass of 8.6 \times 10^{-3} \; \text{mol} \times 60.09 \; \text{g} \cdot \text{mol}^{-1} = 0.52 \; \text{g}

What is the oxidation state for a Mn atom?<br> (1) 0 (2) +7 (3) +3 (4) +4
ss7ja [257]

Answer : The correct option is, (1) 0

Explanation :

Oxidation state or oxidation number : It represent the number of electrons lost or gained by the atoms of an element in a compound.

Oxidation numbers are generally written with sign (+ and -) first and then the magnitude.

When the atoms are present in their elemental state then the oxidation number will be zero.

As per question, 'Mn' atom is a free element that means it is present in their elemental state then the oxidation state will be zero.

Hence, the correct option is, (1) 0
