Answer:
Mass = 2.77 g
Explanation:
Given data:
Mass of HCl = 2 g
Mass of CaCl₂ produced = ?
Solution:
Chemical equation:
2HCl + Ca → CaCl₂ + H₂
Number of moles of HCl:
Number of moles = mass / molar mass
Number of moles = 2 g/ 36.5 g/mol
Number of moles = 0.05 mol
now we will compare the moles of HCl with CaCl₂.
HCl : CaCl₂
2 : 1
0.05 : 1/2×0.05 = 0.025 mol
Mass of CaCl₂:
Mass = number of moles × molar mass
Mass = 0.025 mol × 110.98 g/mol
Mass = 2.77 g
Answer:
1. Flower
- contain the sexual organs of the plant
- attract insect for pollination
- produce fruit carries the seed during fertilization.
2. Leaf
- capture sunlight for photosynthesis
- responsible to make food
- evaporate water molecules
- movement of oxygen and carbon dioxide in and out to plant
3. Stem
- transport water and nutrients from root to leaves.
- support leaves and branches
- in some plants are photosynthetic
4. Root
-provide support by anchoring the plant
- absorb water and nutrients for growth
- store sugars and carbohydrates to perform other functions
