Since light waves can travel through an empty vaccum (which is what it is happening in this scenario) the sun radiates the light to us even though it takes 8 minutes to get here

also think of a lamp or a light on the ceiling as soon as you turn it on the light comes on to and if you were to put your hand on the light when it is on you will feel heat and the suns rays work the same way

Which of the following does NOT demonstrate the law of conservation of matter?
Brrunno [24]

The one that does not demonstrates the law of conservation of matter would be the third option: 2NO_2 + H_2O -- > HNO_3 + HNO_2

<h3>What is law of conservation of matter? </h3>

It is a law that explains that matters are conserved during the course of chemical reactions. They can neither be destroyed nor created.

Thus, the number of moles of the species in a reaction remains the same before and after the reaction.

Thus, an equation that demonstrates the law of conservation of matter will be balanced in terms of the number of moles of species.

The only equation, in this case, is 2NO_2 + H_2O -- > HNO_3 + HNO_2

There are 3 oxygen species on the reactant while 5 are present on the product side.

Why do different isotopes of an element generally have the same physical and chemical properties?
tresset_1 [31]

Answer:

The correct answer is because they have same number of protons but different number of neutrons.

Explanation:

Isotopes are atoms of the same element but differ only in the number of neutrons in the nucleus, i.e. they have same atomic number but different mass number.

Mass number is affected as they have different number of neutrons, thus effecting their physical properties.

The number of electrons and protons are same, i.e. their atomic number is same and thus their chemical properties are same as chemical properties are determined by the atom’s electronic configuration and that relates to number of protons.
