Answer:
The answer is
<h2>5.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%20%5C%5C%20)
From the question
mass = 35 g
volume = 7 cm³
The density is
![density = \frac{35}{7} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B35%7D%7B7%7D%20%20%5C%5C%20)
We have the final answer as
<h3>5.0 g/cm³</h3>
Hope this helps you
Answer:
An ionic compound is formed when there is a reaction between the elements whose ions are electrostatically attracted.
Explanation:
The ionic compounds form crystalline networks with ionic bonding. Electrostatic attraction is a very strong bond that is very difficult to break. The stability of the ionic compound depends on the lattice energy, the higher it is, the more stable the compound is and the lattice energy is that which is released in the formation. At room temperature they are always in a solid state, because the bonds are very close and as stated before, they are difficult to break (providing a lot of energy)
Answer:
: conjugate acid of ![SO_3^{2-}](https://tex.z-dn.net/?f=SO_3%5E%7B2-%7D)
: conjugate base of ![CH_3NH_3^+](https://tex.z-dn.net/?f=CH_3NH_3%5E%2B)
: conjugate base of ![HSO_3^-](https://tex.z-dn.net/?f=HSO_3%5E-)
: conjugate acid of ![CH_3NH_2](https://tex.z-dn.net/?f=CH_3NH_2)
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
![HSO_3^-+CH_3NH_2\rightleftharpoons SO_3^{2-}+CH_3NH_3^+](https://tex.z-dn.net/?f=HSO_3%5E-%2BCH_3NH_2%5Crightleftharpoons%20SO_3%5E%7B2-%7D%2BCH_3NH_3%5E%2B)
Here in forward reaction
is accepting a proton, thus it is considered as a base and after accepting a proton, it forms
which is a conjugate acid.
And
is losing a proton, thus it is considered as an acid and after loosing a proton, it forms
which is a conjugate base.
Similarly in the backward reaction,
is loosing a proton, thus it is considered as a acid and after loosing a proton, it forms
which is a conjugate base.
And
is accepting a proton, thus it is considered as a base and after accepting a proton, it forms
which is a conjugate acid.
Answer:
Sunlight penetrates the top layers of the ocean, so photosynthesis occurs there.
Explanation:
Manganese alone cannot be a catalyst. However, its oxides can work as a catalyst. Manganes (II, III) oxide has found some applications in certain reactions as a catalyst. These reactions are the oxidation of methane, carbon monoxide, decomposition of NO and the catalytic combustion of organic compounds.
