Answer:
we can talk any time any day
Explanation:
Answer is: l<span>ight-dependent reactions and l</span>ight-independent reactions (dark or carbon reactions or <span>Calvin cycle).
</span>In photosynthesis (<span>convert </span>light<span> energy into </span>chemical energy)<span>,
the carbon in carbon(IV) oxide is being reduced to form glucose.
</span>The pigment chlorophyll<span> absorbs one </span>photon<span> and loses one </span>electron (it passed throw <span>an </span>electron transport chain) in the light-dependent reactions.
<span>The </span>enzyme RuBisCO takes carbon(IV) oxide i<span>n the </span><span>light-independent reactions.</span><span>

The Alkali Metals- (Group 1A)can be found (excluding hydrogen) in the first column of the periodic table. They all have 1 valence electron and tend to form +1 cations when forming Ionic bonds with non metals.
The Alkali Earth Metals: (Group 2A) can be found in the second column/group on the periodic table. These elements form +2 positively charged cations when forming Ionic bonds with non metals. They also all have 2 valence electrons.
The Halogens: are the elements that make up the second to last group on the periodic table. These elements include Chlorine, Fluorine, Bromine, Iodine, and Astatine. These elements have 7 valence electrons. The usually form a -1 charged anion when forming ionic bonds with metals.
The Noble gases: the very last group on the periodic table. All these elements have 8 valance electrons. Due to the octet rule these atoms are already very stable and rarely react with other elements.
Answer:
1.196 M NaOH
Explanation:
Molarity = moles/Volume (L)
moles NaOH = mass NaOH/MM NaOH = 12/40.01 = 0.299 moles NaOH
Volume solution = 250 mL = 0.250L
M = 0.299/0.250=1.196 M NaOH
