Answer:
The answer to this problem is c
Explanation:
Explanation:
Potassium Iodide -
It is a salt , which is made of the ions of potassium and iodine ,
Potassium being the cation , and iodide being the anion .
The ions of this salt are held by strong ionic forces , which hold the ions together very strongly .
Hence , a lot of energy is required to melt the salt , as the bond between the ions is very strong .
Hence , the melting point of this salt , i.e. , Potassium Iodide , is very strong .
Answer:
The substance has a density of 2.636 grams per mililiter.
Explanation:
We must remember that density (), measured in grams per mililiters, is the mass of the substance (), measured in grams, divided by its volume (), measured in mililiters. That is:
In addition, a kilogram equals 1000 grams and a liter equals 1000 mililiters. If we know that and , then:
The substance has a density of 2.636 grams per mililiter.
Answer:
it's a precipitation reaction.
Explanation:
the solid produced is insoluble with water–making it a precipitate.
Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.
There is no isomer of CH3OH or methanol because it contains only one carbon atom. And also, the structure is tetrahedral, having four substances attached to the carbon atom.
(2) deposition (4) fission
Answer:The correct answer is option (4).
Explanation:
Nuclear reaction :These the chemical reaction in which change in identity of a nucleus of an atom takes place.It is of two types:
From the given options the option identifying the nuclear reaction is fission.Hence. the correct answer is option 4.
b) 1000 g / 1 kg
c) 1000 kg / 1000 g
d) 1 kg / 1000 g
Answer:
option d = 1 kg/ 1000 g
Explanation:
Given data:
Mass of sodium acetate = 340 g
Mass of sodium acetate in Kg = ?
Solution:
Gram and kilogram both are units of mass. Kilogram is larger unit while gram is smaller unit. The one kilogram equals to the 1000g. In order to convert the given value into kilogram the value must be multiply with 1 Kg/ 1000g.
340 g × 1 Kg/ 1000g
0.34 Kg
