<span>I would say D AlCl3.
covalent bonding is when 2 or more elements share electrons (usually when nonmetals bond with nonmetals)
ionic bonding is when one element steals another's electrons (usually when nonmetals bond with metals)</span>
Answer;
D. Formation of NADPH
Explanation;
During the process of photosynthesis light is converted to chemical energy.
During stage 1, Excited electrons that leave the chlorophyll pigments in stage 1 are used. Excited electrons are passed through proteins in the thylakoid membrane like a ball being passed from person to person. H2o molecules split and turn into H+ molecules and O2 gas, then pigments take the electrons from the split water molecules and release O2 into the atmosphere.
During stage 2; electrons from 1st cluster pump H+ ions into the thylakoid membrane through the hydrogen ion pump (protein membrane. Higher concentration of H+ ions inside the thylakoid membrane compared to outside. H+ ions diffuse out of the thylakoid throught the ATP synthase (enzyme in membrane). ATP synthase catalyzes the reaction ADP + P ---->ATP.
Stage 2; Excited electrons + H+ ions + NADP+= NADPH
Answer:
<em><u>D</u></em><em><u> </u></em>all
Explanation:
because law of conservation of mass describes A, B and C statement
The answer would be: carbon dioxide(CO2) and water (H2O).
The combustion of methane gas family typically will result in carbon dioxide and water. It will need many oxygen gases to do the combustion. The reaction equation would be:
<span>C4H8(l) + 6O2(g) ==> 4CO2 + 4H2O</span>
The question requires to balance the equation.
The equation is already balanced, so the answer is:
<span>Ca(s)+Br2(l)⟶CaBr2(s)
</span><span>
</span><span>
</span><span>Explanation:
</span><span>
</span><span>
</span><span>1) The phases are identified with a letter to the right of the compound or element:
</span><span>
</span><span>
</span><span>So, for Ca, the phase is (s) which means solid.
</span><span>
</span><span>
</span><span>For Br₂ (l) the phase is (l) which means liquid.
</span><span>
</span><span>
</span><span>For CaBr₂(s) the phase is (s) which means solid.
</span><span>
</span><span>
</span><span>2) The core work of balancing is make the number of atoms of each element on the reactants equal to the same number of atoms on the products side.
</span><span>
</span><span>
</span><span>That is the law of conservation of mass applied to chemcial reactions.
</span><span>
</span><span>
</span><span>3) So, you have to add coefficientes on the right place to make the number of atoms on the left side equal to the number of the same kind of atom on the right side.
</span><span>
</span><span>
</span><span>In this table you can verify that the equation given is balanced:
</span><span>
</span><span>
</span><span>atom left side right side
</span><span>
</span><span>Ca 1 1
</span><span>
</span><span>Br 2 2
</span><span>
</span><span>So, you do not need to modify any coefficients.
