Answer: for the first question, Hypochloride is being released from your bleach to oxidize your fabric. As you know oxidation simply mean addition of oxygen, so when hypochloride (ClO-) comes in contact with fabric oxygen is added and some organic bonds are broken and the dirt is washed out.
For the second question. The melting and boiling point of pure substance is sharp. Like water has 100oC boiling point and OoC melting point. So anything from that means it has impurities in it. Just like if you make tea, you have introduce something else into the water, if you should try boiling your tea, you'll find out that the boiling point is not going to 100oC anymore. Every other liquid have their boiling point and melting point. When you know them, you'll be able to determine the purity.
Answer:
nonmetal
Explanation:
In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Answer:
The number of moles of CO2 is 0,54
Explanation:
We use the formula PV=nRT. The conditions of STP are 1 atm of pressure and 273 K of temperature.
PV=nRT n=PV/RT
n=1 atm x 12 L/0,082 l atm/K mol x 273K
n=0,536049316 moles
Answer:
there should be a picture to go with this question. it will give you the mass which is needed to calculate the density.
Answer:
A substance containing only one type of atom is a chemical element.
