Answer: 1) endothernic
2) Yes absorbed
Explanation:
Decomposition is a chemical reaction in which one reactant gives two or more than two products. All decomposition reactions are endothermic reactions as energy is absorbed to break the bonds.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and
for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and
for the reaction comes out to be negative.
The best answer here is B , i.e. the components of a homogenous mixture are evenly distributed
This means the constituents are mixed uniformly.
In a heterogeneous mixture, the constituents are not mixed uniformly.
Some good examples of a homogeneous mixture are:
1. Sugar solution
2. Soda
3. Water
5. soft drinks
6. Air
7. Vinegar
8. Brine
Some examples of a heterogeneous mixture are:
1. Blood
2. Milk
3.Water and oil
4. Water and sand
5. Soil
6. Hollandaise sauce
8. smog
Answer:

Answer:
Mass of chlorine = 47.22 g
Explanation:
Given data:
Mass of sodium = 30.5 g
Mass of chlorine= ?
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
Number of moles of Na:
Number of moles = mass/molar mass
Number of moles = 30.5g/ 23 g/mol
Number of moles = 1.33 mol
Now we will compare the moles of Cl
₂ with Na from balance chemical equation.
Na : Cl
₂
2 : 1
1.33 : 1/2×1.33 = 0.665 mol
Mass of chlorine gas:
Mass = number of moles × molar mass
Mass = 0.665 mol × 71 g/mol
Mass = 47.22 g
