Answer: Cotyledons are the first leaves to emerge from the soil when a plant germinates. Because they are part of the seed's embryo, they also are known as seed leaves, and provide nutrients to the seedling until its true leaves unfurl and begin the process of photosynthesis.
Explanation:
Answer:
M(NaSO4)=23+32+16*4=119 g/moles
n=200/119=1.68
Explanation:
Heat required in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC (T2-T1)
Heat = 10.0 g (4.18 J/g-C ) ( 6.0 C )
<span>Heat = 250.8 J</span></span>
Answer:
Statements B (1-hexene will show an absorption at 1650cm-1 but cyclohexane will not)
C (both cyclohexane and 1-hexene will show C-H absorptions at about 2950cm-1)
are both true
