The first blank is a compound, second is a mixture
Answer:
protons and neutrons
Explanation:
protons and neutrons is equal to mass number
D would be your best bet because evaporation occurs when water is heated, it then vibrates and then magic!
2.565L
Explanation:
- Charles law states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.V/T=K
V1/T1=V2/T2
Unit of Kelvin = 273.15
- To get the absolute temperature, we need to convert the degree celsius temperature to kelvin.
T1= 22+273.15= 295.15 K
T2 = 71+273.15= 344.15 K
V1 = 2.20 L
V2 =?
2.20/295.15=V2/344.15
0.00745 x 344.15 = 2.565 L
Hence, 2.565 L is the new volume of the balloon.
They define acids as proton donors, and bases as proton acceptors
If you were to have:
HNO3 + H2O -> H3O+. + NO3-
You can see that the nitric acid (HNO3) gave a hydrogen ion which has 1 proton, 0 neutrons and 0 electrons to the water so we just say that it gave a proton.
Now let's see a base
NH3 + H2O -> NH4+ + OH-
Now, you can see that the ammonia (NH3) gained a hydrogen ion (proton) from the water to become ammonium(NH4). which means it accepted a proton
That's basically it. Feel free to ask if you have any further questions
