Which idea did isaac newton’s experiments with light support?
(a) light is produced by the interaction of magnetic and electric fields.
(b) light is a wave because it has properties that are similar to radio waves.
(c) light is made of particles because it travels only in a straight path.
(d) light is a wave because it bends around barriers.

(C) Light is made of particles because it travels only in a straight path.

The correct answer is option C, that is, light is made of particles as it travels only in a straight path.  

According to Isaac Newton, the geometric nature of refraction and reflection of light could only be illustrated if the light was formed of particles, which is considered as corpuscles, as the waves do not seem to travel in a straight path. Newton disapproved theory of Christiaan Huygens that light was formed of waves.  

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

explanation: no but i do not usually comment
