Answer:
Its a chemical change.
Explanation:
When baking soda and vinegar are mixed bubbles formed and new product is formed by both reactant. So its a chemical change because in a chemical change new substances are formed.
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg .
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
To find the mass in grams of Selenium, you use the moles you have and multiply it by the molar mass.
5489 Moles Se * (79g Se / 1mole Se) =433631g of Se
No they can't because the definition of an element is, something that exists as a single atom
For example, oxygen is an element and can't be broken down anymore however, it can be combined with hydrogen to make water
Answer:
Homologous series is defined as a systematic order of structurally similar organic compound containing same functional group in their family and two adjacent members differ in their molecular formula by -CH2 unit.
Characteristics:
1.Various members of homologous series contain same functional group.
2.Various members of homologous series can be represented by common formula.
3. All members of a homologous series have almost similar chemical properties.
4. All members have common method of preparation.
5.Two successive members of homologous series have different chain length or difference in their molecular formula by -CH2 unit.
6.The members of homologous series show different physical properties.
Answer:
Oxidized,Reduced,reductant,oxidant, NAD+,NADH
Explanation:
1 when a compound donates electrons the compound becomes oxidized.such a compound is referred to as electron donor.
2 when a compound accept electron the compound becomes reduced such a compound often referred to as electron acceptor.
3 In glycolysis once the carbon containing compound that functions as electron donor is reductant.
4 once the electron donor in glycolysis gives up its electron ,it is oxidized to a compound called oxidant.
5 NAD+ is the compound that function as electron acceptor in glycolysis.
6 The reduced form of electron acceptor in glycolysis is NADH.
