The mass of Ca(CN)2 : 92,11 g/mol
<h3>Further explanation</h3>
Given
0.0321 moles of Ca(CN)2
Required
The mass
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mol(n) = mass(m) : MW(molecular weight)
Input the value :
mass = mol x MW Ca (CN)2
mass = 0.0321 x 92,11 g/mol
mass = 2.957 g
Explanation:
Plants are autotrophic organisms which prepare their food with the help of photosynthesis. Plants can have both asexual or multi-sexual reproduction.
Amoeba is a single celled eukaryotic organism. It moves through pseudopodia and it does not have any definite shape. Amoeba can have only asexual reproduction.
The given functions for amoeba and plants are sorted as follows.
Functions of Amoeba:
- has only offspring with identical genes and traits.
- surrounds and engulfs food particles.
- move freely in their environment.
Functions of Plants:
- makes food from carbon dioxide,water, and sunlight.
- can have offspring with different genes and traits.
Answer:
pH Affects Nutrients, Minerals and GrowthBefore
a nutrient can be used by plants it must be dissolved in the soil solution. Most minerals and nutrients are more soluble or available in acid soils than in neutral or slightly alkaline soils.
