We are asked to convert 25 cg to units of hg.
1 cg = 1 centigram = 10⁻² g
1 hg = 1 hectogram = 10² g
The options given are:
a) 1 hg/ 10² g
b) 10² cg/ 1 hg
c) 10² hg/ 1 cg
d) 10⁻² g/ 1 cg
To convert 25 cg to 1 hg, we could convert the 25 cg to grams first, then grams to hg.
25 cg · 10⁻² g/ 1cg = 0.25 g
Here we have converted our number from cg to grams. We can use another conversion of grams to hg to complete the conversion.
0.25 g · 1 hg/ 10² g = 0.0025 hg
Therefore, the first conversion we used was d) 10⁻² g/ 1 cg.
Answer:
See explanation
Explanation:
We know that the process of the oxidation of SO2 to SO3 is catalysed by NO2 gas. It occurs in two stages and i will show the balanced reaction equation of the both stages below;
Step 1
2NO2(g) + 2SO2(g) ------> 2NO(g) + 2SO3(g)
Step 2
2NO(g) + O2(g) -------> 2NO2(g)
So, the overall reaction equation is;
2SO2(g) + O2(g) ------> 2SO3(g)
Hydrophobic molecules tend to be nonpolar molecules that group together to form micelles rather than be exposed to water. Hydrophobic molecules typically dissolve in nonpolar solvents (e.g., organic solvents).
1. the Moon must be in line with the Earth and Sun - New Moon for a solar eclipse and Full Moon for a lunar eclipse.2. the Moon must be at one of its nodes. Most of the time the Moon at New or Full passes above or below the Sun because its orbit is tilted relative to the ecliptic. An eclipse can occur only when it is at a node, in other words crossing the ecliptic.
Answer:
The sequence of an amino acid P is:
Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile
Explanation:
Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named trypsin:
- Glu-Gly-Lys,
- Gln-Val-Ile
- Ala-Ser-Phe-Lys
Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named chymotrypsin:
- Lys-Gln-Val-Ile,
- Glu-Gly-Lys-Ala-Ser-Phe
In order to determine the sequence of protein P , we will arrange fragments in such a way so that common fragments or the common parts of fragments should come under each other.
On arranging these fragments :
Glu-Gly-Lys-Ala-Ser-Phe
Glu-Gly-Lys
Ala-Ser-Phe-Lys
Lys-Gln-Val-Ile
Gln-Val-Ile
The sequence of an amino acid P is:
Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile
