vampirchik [111]

Here are some examples for those type of reactions.

Combustion reaction: CH4(g) + 2 O2(g) --> CO2(g) + 2 H2O(l)

Decomposition reaction: CaCO3(s) ---> CaO(s) + CO2(g)

Double replacement: AgNO3(aq) + NaCl(aq) ---> AgCl(s) + NaNO3(aq)

One common thing in all is that they are reactions. They have reactants to form new substances called product.

What are these associated with the solar wind

Serjik [45]

Answer:

The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. ... Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona, which in turn is a result of the coronal magnetic field.

A molecule contains five atoms and has a molecular weight of 85 g per mole. the atoms are of elements with atomic numbers 1, 6,

inessss [21]

Answer:

Dichloromethane

Explanation:

As we know the atomic number given belongs to following elements, i.e.

Atomic # Element M.Mass

1 Hydrogen 1 g.mol⁻¹

6 Carbon 12 g.mol⁻¹

17 Chlorine 35.5 g.mol⁻¹

Also the molecular formula of Dichloromethane is,

= CH₂Cl₂

Putting molar masses of each element,

= (12)₁ + (1)₂ + (35.5)₂

= 12 + 2 + 71

= 85 g.mol⁺¹

Result:

Hence the only possible structure containing 5 atoms is Dichloromethane.

In the reaction MnO₂ + 4HCI MnCl₂ + 2H₂O + Cl₂, which species is reduced?

Triss [41]

Answer:

4 HCl (aq) + MnO2 (s) → MnCl2 (aq) + Cl2 (g) + 2 H2O (l)

This is an oxidation-reduction (redox) reaction:

MnIV + 2 e- → MnII (reduction)

2 Cl-I - 2 e- → 2 Cl0 (oxidation)

MnO2 is an oxidizing agent, HCl is a reducing agent.

Reactants:

HCl – Chlorane, Hydrogen chloride

Other names: Hydrochloric acid
Appearance: Colorless, transparent liquid, fumes in air if concentrated; Colorless gas; Colourless compressed liquefied gas with pungent odour; Colorless to slightly yellow gas with a pungent, irritating odor. [Note: Shipped as a liquefied compressed gas.]

MnO2 – Manganese oxide, Manganese(IV) oxide

Other names: Manganese dioxide, Pyrolusite, Hyperoxide of manganese

Appearance: Brown-black solid Black-to-brown powder

Products:

MnCl2 – Manganese(II) chloride, Manganese dichloride

Other names: Manganous chloride, Manganous dichloride Manganese(II) chloride (1:2)

Appearance: Pink solid (tetrahydrate)

Cl2

Names: Chlorine, Molecular chlorine

Appearance: Greenish-yellow compressed liquefied gas with pungent odour ; Greenish-yellow gas with a pungent, irritating odor. [Note: Shipped as a liquefied compressed gas.]

H2O – Water, oxidane

Other names: Water (H2O) Hydrogen hydroxide (HH or HOH) Hydrogen oxide

Appearance: White crystalline solid, almost colorless liquid with a hint of blue, colorless gas

What are the characteristics of different classes of chemical reactions?

Ganezh [65]

Answer:

· A chemical reaction is a process generally characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them.
