Answer:Nitrogen dioxide reacts with the sunlight and combines with particles from smoke and soot to form industrial smog. is true
Explanation:
16
Explanation:
The subatomic particles in any atom are made up of protons, neutrons and electrons in it.
Protons are the positively charged particles.
Neutrons do not carry any charges.
Together with protons, they occupy the nucleus.
Electrons are negatively charged particles.
In an atom of B - 11;
11 is the mass number
mass number = number of protons + number of neutrons.
Total subatomic particles = proton + neutrons + electrons
TSP = mass number + electrons
In B, the atomic number = 5 = number of electrons
TSP = 11 + 5 = 16

I believe that the answer is B
1.38 moles of oxygen
Explanation:
Thermal decomposition of Lead (II) nitrate is shown by the balanced equation below;
2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂
The mole ration of Lead (II) nitrate to oxygen is 2: 1
Therefore 2.76 moles of Lead (II) nitrate will lead to production of? moles of oxygen;
2: 1
2.76: x
Cross-multiply;
2x = 2.76 * 1
x = 2.76 / 2
x = 1.38
Answer:
The answer is given below:
Explanation:
Strong acids have the ability to dissociate quickly as compared to the weak acids which dissociates slowly and can do that up to a certain level.
HCl is a strong acid and HA as stated in the statement is a weak acid.
So, in the beaker which contains HCl will have:
In the beaker with HA will have:
