Objects can be charged when electrons move from one object to another by direct contact 1.Charging by conduction (contact) 2.Charging by conduction (contact), , 3.Charging by friction 4.Static electricity charging by induction
Answer:
Charging by conduction (contact)
Static electricity charging by induction
Explanation:
A body can be charged when another body is made to touch it such that charges are transferred from a charged body to an uncharged body. This is known as charging by contact.
A body can also be charged by induction. In this case, a charged body is only brought near an uncharged body without really touching the uncharged body. Charges are transferred without physical contact of the bodies.

why is mineral water a compound
Answer:
Because it is made up of different minerals which are chemically combined.
Explanation:
how do isotopes of an atom differ? how are they the same?
Answer: Isotopes of an atom are different because they have different atomic masses and different number of neutrons within their nucleus. They are the same since they will always have the same atomic number/number of protons in their nucleus.

When 5.0g of NH4CLO4 is added to 100mL of water in a calorimeter, the temperature of the solution formed decreases by 3.0C?
Answer:
24.7 C
Explanation:
I don't know how
The final temperature of 1000 ml water by the addition of 5 g ammonium perchlorate has been 24.7 degree Celsius.
With the addition of 5 g of ammonium perchlorate, the drop in temperature has been:
The addition of 5 g sample to 100 ml water has absorption of energy, that results in change in temperature of 3 degree Celsius.
The heat absorbed by sample has been given as:
Heat = mass × specific heat × change in temperature
Since, the same mass of sample has been added to 25 degree Celsius water, according to law of conservation, the change in density for both the changes has been equivalent.
The ratio of masses has been equivalent to the ratio of volume.
[tex]\rm \dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;=\;\dfrac{Volume\;at\;1000\;ml}{Volume\;at\;100\;ml}\\\\\\\dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;=\;\dfrac{1000\,ml}{100\;ml}\\\\\\\dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;=\;10[/tex]
Since, the mass at 100 ml and mass at 1000 ml has been equal, the heat absorbed by the sample has also been equal. Equating the values:
Mass at 100 ml × Specific heat × Change in temperature = Mass at 1000 ml × Specific heat × Change in temperature
[tex]\rm 3\;degree\;Celsius\;= \;\dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;\times\;Change\;in\;temperature\\\\3\;degree\;Celsius\;= \;10\;\times\;Change\;in\;temperature\\\\Change\;in\;temperature\;=\;\dfrac{3}{10}[/tex]
Change in temperature = 0.3 degree Celsius.
The initial temperature of water has been 25 degree Celsius. The change in temperature has been given by:
Change in temperature = Initial temperature - Final temperature
0.3 degree Celsius = 25 degree Celsius - Final temperature
Final temperature = 25 - 03 degree Celsius
Final temperature = 24.7 degree Celsius.
The final temperature of 1000 ml water by the addition of 5 g ammonium perchlorate has been 24.7 degree Celsius.

Ba(CN)2
What is the name of the compound?
Answer:
Barium cyanide
Explanation:
I don't no
The name of the compound Ba(CN)₂ is called barium cyanide.
The compound Ba(CN)₂ is called barium cyanide. It is a white crystalline solid that is soluble in water. Barium cyanide is a toxic compound and can be fatal if ingested. It is used in electroplating and other metallurgical processes.
The name of the compound is derived from the names of the elements that make up the compound. Barium is named after the Latin word for "heavy", and cyanide is named after the Greek word for "blue". The -ide suffix indicates that the compound is an ionic compound, with barium as the cation and cyanide as the anion.
The chemical formula for barium cyanide can be written in a few different ways. The most common way is to write it as Ba(CN)₂. This formula shows that there is one barium atom for every two cyanide atoms. The formula can also be written as BaCN₂, but this is less common.

Total dosage of medicine to be taken in a day
[tex]= 2 * 875 \\= 1750[/tex]mg
Total weight of one pill [tex]= 250[/tex] mg
Number of pills required is equal to total dosage of medicine divided by the weight of one pill.

Help me plz!
Answer:
Please find attached the table of classification of the chemical compounds, created with Microsoft Word
Explanation:
The given compounds are;
H₂SO₃ is an acid which is known as sulfurous acid
When SO₂ is added to water, we have;
SO₂ + H₂O ⇄ HSO₃ + H⁺
Therefore, H₂SO₃ is ionic
2) HI which is known as hydrogen iodide, dissolves in water as follows
HI (g) + H₂O (l) ⇄ H₃O⁺(aq) + I⁻(aq)
Therefore, HI is able to donate hydrogen ions therefore, it is both acidic and ionic
3) KI is a salt of the alkali metal, potassium, and iodine which is a group 7 element such that it formed by the transfer of electrons from potassium to iodine making it an ionic compound
KI forms a slightly alkaline solution
4) NaClO₃ comprises of the ionic combination of sodium and chlorate ions which dissolves in water as follows;
NaClO₃ → Na⁺(aq) + ClO₃⁻(aq)
Therefore, NaClO₃ is ionic
NaClO₃ is also a strong oxidizing agent, making a Br∅nsted acid
we have;
Sulfurous acid (also Sulfuric(IV) acid, Sulphuric acid (UK), Sulphuric(IV) acid (UK)) is the chemical compound with the formula H2SO3. There is no evidence that sulfurous acid exists in solution, but the molecule has been detected in the gas phase.[1] The conjugate bases of this elusive acid are, however, common anions, bisulfite (or hydrogen sulfite) and sulfite.
