Explanation:
where is the statement Boss??
A substance where almost all have the same atomic number of protons
Answer:
C
Explanation:
Single replacement reactions is when only one element gets replaced / changed. This usually looks like this: A + BC = B + AC or A + BC = C + AB
Therefore, the number of reactants must be equal to the number of products, since no actual combinations / break ups are occurring.
Answers A and D are eliminated right away since the number of products don't equal the number of reactants.
Answer B is wrong because it does not show simply one element being replaced, instead, two compounds are being formed. It doesn't look like the example given.
Only answer C shows that one element is replaced:
The iodine is replaced with bromine to form NaBr + I2
Protons and neutrons are made up of tiny particles called quarks.
A proton is a baryon made up two Up and one Down quark.
A neutron is made of two Down quarks and one Up quark.
The Up quarks possess a 2/3 positive charge while the Down quark possess a 1/3 negative charge.
When we refer that a proton consists of two Up quarks and a Down, this simply means that its net appearance matches this description.
It is thought that quarks themselves are surrounded by gluons.
Gluons are the basic particles underlying the strong interaction between protons and neutrons in the nucleus.
