Chlorophyll pigment found in chloroplast of leaves absorbs sunlight.
The plants has a technique in which they lean towards sunlight which helps them better to compete for sunlight.
Explanation:
The leaves of the plant consist of chloroplasts in which light absorbing pigment chlorophyll is found. The chloroplast consist of thylakoid where light reaction of photosynthesis takes place.
The presence of chlorophyll a in large amount would help plant better use the sunlight this amounts to increase number of chloroplast.
Leaning towards the sunlight is feature which helps them using more sunlight.
Well it's an alkali metal if that's what you're asking<span />
Answer:
0.0084
Explanation:
The mole fraction of BaCl₂ (X) is calculated as follows:
X = moles BaCl₂/total moles of solution
Given:
moles of BaCl₂ = 0.400 moles
mass of water = 850.0 g
We have to convert the mass of water to moles, by using the molecular weight of water (Mw):
Mw of water (H₂O) = (2 x 1 g/mol)+ 16 g/mol = 18 g/mol
moles of water = mass of water/Mw of water = 850.0 g/(18 g/mol) = 47.2 mol
The total moles of the solution is given by the addition of the moles of solute (BaCl₂) and the moles of solvent (water):
total moles of solution = moles of BaCl₂ + moles of water = 0.400 + 47.2 mol = 47.6 mol
Finally, we calculate the mole fraction:
X = 0.400 mol/47.6 mol = 0.0084
Answer:
The solidifying/cooling and crystallizing of magma causes igneous rocks to form.
High temperature and low pressure<--Most likely
Low temperature and high pressure<----Less likely.
So the answer to this is Low temperature and high pressure.
