Mg⁺² + 2Cl⁻ = MgCl₂
n(Mg⁺²)=0.25 mol
n(Cl⁻)=2n(Mg⁺²)
n(Cl⁻)=2*0.25=0.5 mol
Answer: Transpiration is a process process in which plants absorb the water through their roots and then release it in the form of water vapour through small pores located in the leaves of the plants.
Explanation:
Transpiration is very important for the life in our planet.
Transpiration is define as a process in which plants absorb the water through their roots and then release it in the form of water vapour.
The process of transpiration occurs through small pores which are located in the leaves of the plants.
Therefore, this process is essential to cool plants and it helps them to mantain their temperature.
The rate of transpiration depends on the following factors:
1. The humidity.
2. The light.
3. The temperature.
4. Water in the soil.
5. Wind.
6. Soil water.
Not sure with the answer, but I hope this helps :/
Answer:
Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels.
Explanation:
The question is incomplete, the complete question is;
The Lewis representation above depicts a reaction between hydrogen (blue) and a main-group element from group______ (red).
In this representation, each Y atom needs ______ electron(s) to complete its octet, and gains these electrons by forming______ bond(s) with atoms of H .
There are ______ unshared electron pair(s) and _______bonding electron pair(s) in the product molecule.
The bonds in the product are _________ (Ionic or Covalent)
Answer:
1) 16
2) 2 electrons
3) 2 bonds
4) 2 unshared pairs of electrons
5) 2 bonding pairs of electrons
6) The bonds in the product are covalent
Explanation:
Group sixteen elements have six electrons on their outermost shell. These include two unshared pairs of electrons and two unpaired electrons. These two unpaired electrons can now be covalently bonded to two hydrogen atoms to give H2Y. The compound H2Y has two lone pairs and two bond pairs of electrons.
H2Y can be a general formula for all hydrides of group 16. They are all very similar in structure but gradually differ in physical and chemical properties according to the graduated variation observed down the group.
