S phase. To produce 2 similar daughter cells, the complete DNA instructions in the cell must be duplicated. its also called the Synthesis Phase.
Answer:
36.63 Torr
Explanation:
You need to use two expressions, one for pressure and the other with the relation of density and height of the column.
For the pressure:
P = h * d * g (1)
h is height.
d density
g gravity
The second expression put a relation between the densities and height of the column so:
d1/d2 = h1/h2 (2)
let 1 be the phthalate, and 2 the mercury.
Let's calculate first the relation of density:
d1/d2 = 13.53 / 1.046 = 12.93
Now with the first expression, we can calculate the pressure so:
P = hdg
We have two compounds so,
h1d1g = h2d2g ---> gravity cancels out
From here, we can solve for h2:
h2 = h1*(d1/d2)
replacing:
h2 = 459 / 12.53
h2 = 36.63 mm
1 mmHg is 1 torr, therefore the pressure of the gas in Torr would be 36.63 Torr
Answer:
Convergent, divergent, transform
Explanation:
Convergent- tectonic plates move towards one another
Divergent- they move away from each other, or in other directions
Transform- tectonic plates slide past/against each other
Beryllium Oxide has a molecular formula Be-O
% covalent character in Be-O = 100 - % ionic character in Be-O
Now,
% ionic character = {1 - exp[(-0.25)(E(Be)-E(O))²]}*100
where,
E(Be) and E(O) are the electronegativity values of Be and O
Based on the Paulings scale:-
E(Be) = 1.57
E(O) = 3.44
% ionic = {1 - exp[(-0.25)(1.57-3.44)²]}*100 = 58.28%
Therefore, % covalent = 100 -58.28 = 41.72%
Ans: b) 41 percent
Answer:
c. in a mixture of gases like air, the total pressure is the sum of the individual partial pressures of the gases in the mixture.
Explanation:
<em>Dalton law is also known as Dalton's law of partial pressure. It simply explains that the total pressure exerted by a mixture of gases in a container is the sum of the individual gas pressure (partial pressure) exerted by each of the gases.</em>
Hence, the correct option is C.
