max2010maxim [7]

Answer:

The number of Chlorine atoms in the product is 2.

Explanation:

The law of conservation of mass states that matter can neither be created nor destroyed in a chemical reaction.

The reactants contain one chlorine molecule(Cl_{2}) which has two chlorine atoms.

Then, according to law of conservation of matter, the product must contain two chlorine atoms.

CAM plants function using crassulacean acid metabolism. Like C4 plants, CAM plants provide preparatory step for the Calvin cycle
poizon [28]

Answer: ORGANIC ACIDS  

Explanation:

CAM PLANTS CARBOXYLATE ORGANICS ACIDS through the addition of  CO2 to PEP Carboxylase(  a phosphoenolpyruvate carboxylase enzyme present in the mesophyll cells of the cytoplasm in a green plant) to produce Oxaloacetate (organic compound).

CO2 + PEP  ⇒ C4H4O5 (oxaloacetate)

Oxaloacetate is then converted to a similar molecule, Malate (C4H6O5,  another form of organic compound) that can be transported in to the bundle-sheath cells. Malate enters the plasmodesmata and releases the CO2. The CO2 then fixed by rubisco and made into sugars via the Calvin cycle.

pshichka [43]

Answer:

a) Sm

Explanation:

Hello,

This substantiation could be done by knowing how to compute the released energy for 1 mol the oxide. Thus, for Sm, the computation turns out into:

Q=-1823.0\frac{kJ}{mol}*\frac{1molSm_2O_3}{348.72gSm_2O_3} *3.540gSm_2O_3\\Q=-18.5kJ

The sign just indicates that the heat is released due to the chemical reaction and it matches with the indicated heat in the statement.

Best regards.
