Write the chemical equation for the formation of HI from the single, isolated H and I atoms.

Chemistry
1 answer:
mart [117]3 years ago
7 0

Answer:

H2 + I2 → 2 HI.

Explanation:

Hydrogen iodide is a diatomic gas which can be readily formed from the direct combination of the elements involved which is hydrogen and iodine. Both elements can be combined by irradiating the mixture with an electromagnetic radiation that has a wavelength which is equal to that needed to break the iodine molecule bond between the two iodine atoms

Why are the properties of a compound different than the elements that make it up.
nexus9112 [7]

The properties of compounds are different, and in some cases very different, from those of the elements that compose them. This is because elements combine in compounds to become completely different substances with unique properties.

Compounds contain atoms of different elements chemically bonded in fixed ratios. An element is a pure chemical substance made up of atoms of the same kind. Compounds contain different elements in fixed ratios, arranged in a defined way by chemical bonds.

This is caused by different base properties where each element has a different number. Due to the number of electrons and differences in shell and valence electrons, different elements bond differently to certain other elements.

Compounds:

is composed of atoms of two or more different elements bonded together, and

can be broken down into simpler types of matter (elements) by chemical (rather than physical) means. from its components, and.

always contains the same proportions of atomic components.

Classify each of the following bonds as non polar covalent polar or ionic
Soloha48 [4]
A) Polar (Cl is more electronegative than Si)
b) Nonpolar (Both atoms have the same electronegativity)
c) Ionic (Ionic bonds happen between a metal and a nonmetal)
d) Nonpolar (Hydrogen and carbon have about the same electronegativity) this is a common nonpolar bond)
You can identify the type of bon by looking at what is being bonded (nonmetal or metal) and the placement of the elements on the periodic table (electronegativity increases going up a group and going from left-right across a period).

A piece of silver releases 202.8 J of heat while cooling 65.0 °C. What is the mass of the sample? Silver has a specific heat of
KiRa [710]

Answer: 13 grams

Explanation:

The quantity of heat energy (Q) released from a heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = 202.8 Joules

Mass of silver = ?

C = 0.240 J/g °C.

Φ = 65°C

Then, Q = MCΦ

202.8J = M x 0.240 J/g °C x 65°C

202.8J = M x 15.6 J/g

M = (202.8J / 15.6 J/g)

M = 13 g

Thus, the mass of silver is 13 grams
