What is the percentage of water in the hydrate cocl2 • 6h2o
lord [1]

Answer:

52.17%

Explanation:

COCl2.6H20

C=12,O=16,Cl=35.5,H=1

Relative molecular mass of COCl2.6H2O= 12+16+71+6(2+16) = 99 + 108= 207g

Relative molecular mass of 6H2O = 108g

Percentage of water = (108/207 )*100

= 52.17%

In one kind of nuclear reaction, two nuclei fuse, or join together, to form a larger nucleus. This kind of reaction happens only
Vladimir79 [104]
High pressures are necessary to create such reaction so that the particles will be able to overcome electrostatic repulsion. The particles that make up a particular atom are covered by shells of energy that react to different impulses like pressure. When particles are exposed to extreme environmental pressure it has the tendency to split its particles and undergo nuclear fusion successfully.

Calculate the percentage composition of oxygen in aluminium nitrate, Al(NO3)3.
kotegsom [21]

Answer:

A small still is separating propane and butane at 135 °C, and initially contains 10 kg moles of a mixture whose composition is x = 0.3 (x = mole fraction butane). Additional mixture (x = 0.3) is fed at the rate of 5 kg mole/hr. The total volume of the liquid in the still is constant, and the concentration of the vapor from the still (xp) is related to x, as follows: Xp = How long will it take for X, to change from 0.3 to 0.35.

23. Using the periodic table, what is the oxidation number of:
Aloiza [94]

Answer:

a. +2

b. +3

c. -1

Explanation:

The typical oxidation states can be determined from the periodic table based on the number of valence electrons an atom has.

a. Calcium belongs to group 2A, meaning it has 2 valence electrons and, therefore, would have an oxidation state of +2 in compounds.

b. Aluminum is in group 3A, meaning it has 3 valence electrons and would have an oxidation state of +3 in compounds when the 3 electrons are lost.

c. Fluorine would become fluorine if it gained 1 additional electron to achieve an octet, so its oxidation state would be -1.
