Answer: 11 Electrons
Explanation: This is because a neutral atom has the same number of protons and electrons.
Answer: obey the law of conservation of mass.
Explanation:
The law of conservation of mass states that matter can not be created nor be destroyed but can be transformed from one form to another. Whenever one balance an equation, if the equation is not balance it means something has be destroyed or created, this we give an ideal that the equation is not balance or wrong.
Answer: C) 
L 
Explanation: 
According to Avogadro's law, 1 mole of every gas occupies 22.4 Liters at STP.
Thus from the balanced chemical equation, 8 moles of hydrogen sulfide reacts with 8 moles of chlorine gas.
i.e 8 moles of hydrogen sulfide reacts with 
of chlorine gas.
2.28 moles of hydrogen sulfide reacts with 
of chlorine gas.
Answer:
H2(g)+I2(s)→2HI(s)
Explanation:
Hello there!
In this case, according to the given information and unbalanced chemical reaction, we infer it must be balanced in agreement with the law of conservation of mass because the reactants side has two hydrogen and iodine atoms whereas the products side has just one. In such a way, by placing a 2 on HI, we obtain the following balanced reaction:
H2(g)+I2(s)→2HI(s)

Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. Sunlight is the primary source of energy on the surface of Earth.
