Answer:

The best term that describes the reaction is addition polymerization

Explanation:

Polymerization is a process which small molecules, monomers, undergo a chemical reaction to form polymer chains. The two general types are: addition polymerization and condensation polymerization.

Addition polymerization occurs when monomers reacts by the opening of the double bond to form a long carbon chain. The reaction continues until the reactive intermediate is destroyed in a termination reaction. This is a major process of producing polymers such as: poly(ethene) and poly(propene). It process has three stages which are: initiation, propagation, and termination.

One of the basic building blocks of matter, which cannot be broken down by chemical means is a(n)______ , of which there are 92

Nadusha1986 [10]

One of the basic building blocks of matter, which cannot be broken down by chemical means is an element.

The first chemical element is hydrogen (atomic number is 1) and the last is oganesson (atomic number is 118).

Elements are scheduled in Periodic table, ordered by their atomic number.

Other example, krypton is a chemical element with symbol Kr and atomic number 36.

Krypton has 36 electron and 36. It is noble gas (group 18).

Noble gases are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.

Many appliances in your home and school use electrical energy. Which of these appliances is intended to convert electrical energ

Solnce55 [7]

Answer:

music amplifier or a loudspeaker

Explanation:

A music amplifier or a loudspeaker are a few devices that convert electrical energy into sound energy.

As it is a well known fact that energy can neither be created nor be destroyed it can only change from one form to the other. As here it is changing from electrical to sound.

You find a compound composed only of element "X" and hydrogen, and know that it is 91.26% element X by mass. Each molecule has 2

worty [1.4K]

Since you know the ratio of atoms, you can start to put a formula togeter. The formula might look like:
XH2.67
but since atoms can't come in fractional amounts, we have to multiply the formula by some number in order to turn 2.67 into a whole #, while still maintaining the ratio. Multiplying 2.67 by 3 yields 8, so the most likely ratio in the molecule is

X3H8so the ratio of 1:2.67 is still maintained. The mass percent tells you that out of every 100g of compound, 91.26g is element X, so the other 8.74g must be H. Dividing each mass by the number of moles in the formula gets us the molar mass of each element (approximately). DIviding 8.74g by 8 gets 1.09, roughly the molar mass of hydrogen. Dividing 91.26g by 3 gets us 30.4, roughly the molar mass of phosphorus. Element X is most likely phosphorus

Mg(OH)2+2 HCI = MgCI2+ H2O

In-s [12.5K]

Answer:

Mg(OH)2 + 2HCI ⇒ MgCI2 + 2H2O

Explanation:

In order to balance a chemical equation you need to make sure both sides of the equations are equal.

Mg(OH)2 + 2HCI = MgCI2 + H2O

Mg = 1

Oh = 2

HCI = 2

Products:

Mg = 1

CI = 2

H = 2

O = 1

2H20 = 1 × 2 = 2

2 × 2 = 4

2HCI

1 × 2 = 2

Mg(OH)2 + 2HCI ⇒ MgCI2 + 2H2O

Hope this helps.
