Answer:
is an aqueous reactant
is a liquid product
is a gaseous product
Explanation:
⇔ 
Hydrogen carbonate dissocates to form carbon dioxide and water. The acid (hydrogen carbonate) is in aqueous form and it dissociates to water (liquid) and carbon dioxide (a gas). It is also seen that the hydrogen carbonate is on the reactant side and it dissociates to produce water and carbon dioxide.
W<u> is an aqueous reactant</u> (a reactant undergoes changes in a chemical reaction
<u />
<u> is a liquid product</u> (product refers to the species produced from chemical reaction)
<u />
<u> is a gaseous product</u>
1) For example, sodium oxide (Na₂O).
One one molecule of sodium oxide has one sodium atome (Na) and two oxygen atoms (O).
The subscript after element shows the number of elements in a molecule.
2) Yes, it possible for two different compounds to be made from the exact same two elements.
This are isomers, same molecular formula, but different arrangements of atoms.
For example, n-butane (C₄H₁₀) and 2-methylpropane (C₄H₁₀).
3) There are large number of compounds in this world, around 40 millions.
Answer:
The correct answer is it adds a UMP molecule to glucose-1-phosphate by splitting out pyrophosphate.
Explanation:
UDP glucose pyrophosphorylase enzyme also known as UTP-glucose-1-phsphate uridylyltransferase.
This enzyme plays an important role during synthesis of glycogen also known as glycogenesis.
During the reaction the enzyme UDP glucose pyrophosphorylase transfer uridine monophosphate to glucose-1-phosphate resulting in the formation of UDP glucose along with the release of pyrophosphate moiety.
Glucose-1-phosphate+UTP⇆UDP-glucose+ppi
Dissolving a solid in liquid is a physical change . For eg table salt in water is a physical change because only the state of the matter has changed. Allowing the water to evaporate will return the salt to a solid state. Thus, dissolving a solid is a physical change.
