Chemistry

Answer:

Experiment you will be able to watch a chemical reaction. In this experiment vinegar (a substance) and baking soda (a substance) will mix together. When mixed together the molecules of the two substances will re-arrange, or change, to make new substances.

Vinegar has acetic acid in it. The chemical name for baking soda is sodium bicarbonate. When you mix the two together you get sodium acetate and water. You also get carbon dioxide, which is a gas. The bag puffs up because carbon dioxide is a gas and takes up a lot of space. Eventually the bag isn't big enough to hold all that carbon dioxide gas so it explodes!

Explanation:

hope it helps ig! :\

1)The limiting reactant will be aluminum acetate

2) The mass of aluminum hydroxide formed will be 9.75 grams.

<h3>Stoichiometric problem</h3>

The equation of the reaction is as below:

Al(C_2H_3O_2)_3 + 3NaOH --- > 3C_2H_3NaO_2 + Al(OH)_3

The mole ratio of the 2 reactants is 1:3.

Mole of 100 mL. 1.25 mol/L Al(C_2H_3O_2)_3 = 0.1 x 1.25 = 0.125 mol

Mole of 300 mL, 2.30 mol/L NaOH = 0.3 x 2.3 = 0.69 mol

Thus, aluminum acetate is limited.

Mole ratio of  Al(C_2H_3O_2)_3 and Al(OH)_3 = 1:1

Equivalent mole of Al(OH)_3 = 0.125 mol

Mass of 0.125 mole Al(OH)_3 = 0.125 x 78 = 9.75 grams.

<span>A wave that moves the matter it passes through up and down is a A) Transverse Wave, and one that moves the matter forward and back is a D) Longitudinal Wave. 

There are two main types of waves, transverse and longitudinal, and I remember them by thinking that the longitudinal wave moves the matter in a longitudinal way (so forward and backward), and the transverse is the wave that moves the matter up and down — <em>a</em><em>cross </em>(since transverse can mean "across") the wave. 

Hope this helped!! xx

How do atoms form a new substance
inessss [21]
Atoms form a new substance by bonding with different atoms.

For example, hydrogen atoms and oxygen atoms bond to form H2O as per this equation:

2H2 + O2 ---> 2 H2O

To understand how to hydrogen and oxygen atoms form water you can write that as:

2 H - H + O - O ---> 2 H - O - H

Each hypen represent a chemical bond.

What is happening is that the H - H atoms and the O - O separate and  bond with different atoms: H bonds to O which in turn bonds to other H.

Also, you have to know that chemical bonds are the result of interaction between the electrons of the valence shell of electrons of each atom. This is,  valence electrons from O interact with valence electrons of H to form the bond H - O.

The interaction may be in different ways depending on the properties of the atoms: the kind of bonds known are metallic, ionic and covalent.
