There is no single charge on iodine (if you are referring to its oxidizing number). Since it can have more than 8 electrons for its outermost shell (really crazy stuff about atomic orbitals!), It can possess many charges. Like it's basic form I- (-1 oxidizing number), IO3- (-7), IO2- (-5), even I3-!
Answer:
a vector with speed and strenght
Explanation:
Answer: Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma . ... This changing of rock types is called the "Rock Cycle". Solid rock can be changed into a new rock by stresses that cause an increase in heat and pressure.
Explanation: Brainiest answer pls
We will use this formlula: Mass in grams = Number of moles x Molecular mass of 1 mole.
Since, we know the avagadro number is 6.02 x 10²³, we only have two unknown values left which are the molecular mass of CH3OH and its mole.
Molecular Mass: C = 12, H= 1, O = 16, since we have C=12, H4 = 4, O = 16, we will add them up: 12 + 4 + 16 =32
We know that one mole of anything = 6.02 x 10²³.
So we will use this formula to find the mole of methanol: Number of moles = Number of molecules / Avagadro number
Number of moles of CH3OH = (9.79 x 10^24)/6.02 x 10²³) = 16.263 moles.
Now we know that the molecular mass = 32 and the mole is = 16.263.
Now we can find its mass by using this formula: <span>Mass in grams = Number of moles x Molecular mass of 1 mole.
</span>
Mass in grams = 16.263 x 32 = 520g
