Answer:

These wavelengths are longer than wavelength of visible light.

These wavelengths form the infra-red part of the spectrum.

Explanation:

Solar spectrum has lies in three parts of the electromagnetic spectrum - Ultraviolet, visible and infra-red.

Visible light lies from 400 nm to 700 nm.

Ultraviolet region precedes visible spectrum and has shorter wavelength than it.

Beyond visible spectrum, infrared part of the spectrum starts and has longer wavelength than it.

The wavelength of sunlight that are greater than 700 nm wavelength have longer wavelength than visible light and lie in the infra-red part of the spectrum.

Answer:

B and C

Explanation:

I think the answer correct is C because you never know in what temperature the block of ice is going to melt but if it says select all that apply its possible that B might be useful.

Compress
Fixed
Melts
Melting Point
Freezing Point
High
Crystalline
Lattice
Unit cell
Amorphous solids

Explanation:

Solids tend to be dense and difficult to compress.

They do not flow or take the shape of their containers, like liquids do, because the particles in solids vibrate around fixed points.

When a solid is heated until its particles vibrate so rapidly that they are no longer held in fixed positions, the solid melts.

Melting point is the temperature at which a solid changes to a liquid. The melting and freezing point of a substance are at the same temperature.

In general, ionic solids tend to have relatively high melting points, while molecular solids tend to have relatively low melting points.

Most solids are crystalline

The particles are arranged in a pattern known as a crystal lattice

The smallest subunit of a crystal lattice is the unit cell

Some solids lack an ordered internal structure and are called amorphous solids.

1. Sulfuric acid is formed when sulfur dioxide gas reacts with oxygen gas and water. Write a balanced chemical equation for the

tekilochka [14]

Answer:

1. Balanced chemical for the given chemical reaction is :

$2SO_2(g) +O_2(g) +2H_2O(l) \rightarrow 2H_2SO_4(aq)$

number of mole of sulphuric acid produced = 12.5 mol

number of mole of oxygen required=6.25 mol

Explanation:

1. Balanced chemical for the given chemical reaction is :

$2SO_2(g) +O_2(g) +2H_2O(l) \rightarrow 2H_2SO_4(aq)$

from above balanced equation it is clearly that ,

2 mole of sulpher dioxide gives 2 mole of sulphuric acid

1 mole of sulpher dioxide gives 1 mole of sulphuric acid

therefore,

12 .5 mole of sulpher dioxide will givs 12.5 mole of sulphuric acid

number of mole of sulphuric acid produced = 12.5 mol

2 mole of sulphur dioxide needs 1 mole of oxygen gas

so,

1 mole of sulphur dioxide needs 0.5 mole of oxygen gas

therefore 12.5 of sulphur dioxide needs $12.5 \times 0.5$ mole of oxygen

number of mole of oxygen required=6.25 mol
