Answer:
![6CO_2 + 12H_2O + Energy->C_6H_{12}O_6 + 6O_2 + 6H_2O](https://tex.z-dn.net/?f=6CO_2%20%2B%2012H_2O%20%2B%20Energy-%3EC_6H_%7B12%7DO_6%20%2B%206O_2%20%2B%206H_2O)
Explanation:
-An endothermic reaction is a chemical reaction that gains or absorbs heat from its surrounding in the form of heat.
-During the reaction, the temperature of the surrounding reduces.
-From the reactions given:
![6CO_2 + 12H_2O + Energy-> C_6H_{12}O_6 + 6O_2 + 6H_2O](https://tex.z-dn.net/?f=6CO_2%20%2B%2012H_2O%20%2B%20Energy-%3E%20C_6H_%7B12%7DO_6%20%2B%206O_2%20%2B%206H_2O)
is the only endothermic reaction.
![6CO_2 + 12H_2O + Energy->C_6H_{12}O_6 + 6O_2 + 6H_2O](https://tex.z-dn.net/?f=6CO_2%20%2B%2012H_2O%20%2B%20Energy-%3EC_6H_%7B12%7DO_6%20%2B%206O_2%20%2B%206H_2O)
The force of gravity does.
Hey there!
A ) PO₄³⁻
The element exhibits resonance (4 times) as there is a double bondwith 1 oxygen and a single with the other 3 oxygen. This switchesin each resonance structure. (I know its weird b/c I leaves Phosphorus with 10 electrons surrounding it)
b) SO₄²⁻
Sulfur is the central atom ,double bond 2 oxygens so that they can only have 4 valence electrons ( the little dots around the oxygen ) ,single bond 2 oxygens ( So that they have 6 valence electrons )
Formal charges are 0 for the two double bonded oxygens [ 6-6 = 0 ]and 0 for the sulfur [ 6-6=0 ]
But the oxygens are -1 [ 6-7 = -1 ]
Since there are two of them, there is a negative charge of -2
Bracket the whole structure and on the top right of the outside ofthe brackets write 2- and include a - (negative sign) next to eachof the single bonded oxygens
Don't forget there are resonance structures. The double bonds canbe placed around any of the oxygens
Hope that helps!
Answer:

Explanation:
Bones, lungs, and the liver are the most common places for cancer cells to spread, or "metastasize." Once in the bone, these cancer cells can form new metastatic tumors.
...
Bone metastasis is more likely with cancers such as:
Breast.Prostate.Lung.Kidney.Thyroid.
Using accurate measurements, using pure chemicals and performing the reaction under the most ideal conditions is important to get a valuable percent yield.
<h3>How we calculate the percent yield?</h3>
Percent yield of any chemical reaction is define as the ratios of the actual yield to the theoretical yield of the product and multiply by the 100.
To get the high percent yield or actual yield of any reaction, we have to perform the reaction under ideal condition because if we not use the standard condition then we get the low rate of reaction. Reactants should be present in the pure form as impurity make unwanted products and reduce the productivity of main product and accurate amount of reactants also important for the spontaneous reaction.
Hence, options (a), (b) & (c) are correct.
