Answer:
Acid neutralizes base to form salt and water while white colour neutralizes black colour to form grey colour.
Explanation:
Neutralization is simply the process whereby an acid and a base are mixed to produce salt and water. Now, this reaction also involves the mixing of the hydrogen ions of the acid and hydroxide ions of the base to form the salt and water. It is similar to mixing 2 paints to form another colour in that in the neutralization reaction 2 compounds are mixed to neutralize each other to form another compound while in mixing black and white to form grey the two colors are mixed together and thereby neutralized to form another colour which is grey.
Answer:
We colect 11.2 L of gas
Explanation:
Let's apply the Ideal Gases Law to solve this:
P . V = n . R .T
where P and T in STP are 1 atm and 273°K
The thing is n which means the number of moles for the gas.
As we know, 1 mol of anything has 6.02x10²³ particles so
6.02x10²³ are occupied in 1 mol of gas
3.00x10²³ are occupied in (3.00x10² .1) / NA = 0.500 moles
So let's go to the formula:
1 atm . V = 0.500m . 0.082 . 273K
V = (0.500m . 0.082 . 273K) / 1atm
V = 11.2L
There is a rule, which says that 1 mol of gas in STP, occupies 22.4L so, since we have half a mole, it will occupy half the volume
The question is in incomplete, so here is the complete question:
Nucleic acids are polymers of just 4 different monomers in a linear arrangement. How many different nucleic acid polymer sequences are possible when the polymer contains 30 monomers?
Polymers are biomolecules formed by monomers. For nucleic acid, like DNA and RNA, as 4 monomers are necessary to "create" 1 polymer, a polymer containing 30 monomers can "produce" 7 different nucleic acid sequences.
1 mole of carbon contains 12 g
Thus, 34.6 moles will contain; 34.6 × 12 = 415.2 g
If a substance contains 89.2 % carbon,
then, (415.2/89.2) ×100 = 465.47 g of the substance will be required to yield 34.6 moles of carbon.
