Answer:
the nucleus and electron cloud is the correct option
b. False
Answer: The given statement is true.
Explanation:
Incineration: It is a technique in which organic substance present in waste material is burned down to break them into its components.
For: Example : Burning of powder of wooden chips gives carbon dioxide gas ,nitrogen-dioxide in small amounts and heat energy.
Although incineration can break down harmful chemicals but the by-product formed are hazardous because:
Hence, the given statement is true.
Answer is: the mass of oxygen is 3.31 grams.
m(NaHCO₃) = 5.8; mass of sodium bicarbonate.
n(NaHCO₃) = m(NaHCO₃) ÷ M(NaHCO₃).
n(NaHCO₃) = 5.8 g ÷ 84 g/mol.
n(NaHCO₃) = 0.07 mol; amount of sodium bicarbonate.
In one molecule of sodium bicarbonate there are three oxygen atoms:
n(NaHCO₃) : n(O) = 1 : 3.
n(O) = 3 · 0.07 mol.
n(O) = 0.21 mol.
m(O) = 0.21 mol · 16 g/mol.
m(O) = 3.31 g.
Answer:
The characteristic properties are hard and brittle solids having high melting and boiling point
Explanation:
Ionic compounds are the type of chemical compounds that are formed by ionic bonding. An ionic compound is composed of two oppositely charged ions that are held together by electrostatic forces of attraction.
They are solids at room temperature and usually have a crystalline structure and have high melting and boiling point. Ionic compounds are hard but also brittle.
B-Models only present macroscopic versions of the submicroscopic.
C-Models help explain phenomena but are not good for predicting events.
D-Models are used throughout science although they are not always accurate.
b. phosphoglucomutase, UDP-glucose pyrophosphorylase, amylo-(1,4α1,6)-transglycosylase, glycogen phosphorylase
c. phosphoglucomutase, amylo-(1,4α1,6)-transglycosylase, UDP-glucose pyrophosphorylase, glycogen synthase
d. UDP-glucose pyrophosphorylase, phosphoglucomutase, amylo-(1,4α1,6)-transglycosylase, glycogen synthase
e. phosphoglucomutase, UDP-glucose pyrophosphorylase, glycogen synthase, amylo-(1,4α1,6)-transglycosylase
Answer:
The answer is (e) : phosphoglucomutase, UDP-glucose pyrophosphorylase, glycogen synthase then amylo-(1,4-1,6)-transglycosylase.
Explanation:
Phosphoglucomutase: Convert glucose-6-phosphate to glucose-1-phosphate.
UDP-glucose pyrophosphorylase: Form UDP-glucose from glucose-1-phosphate.
Glycogen synthase: Add the new glucose from UDP-glucose to the growing glycogen chain.
Amylo-(1,4-1,6)-transglycosylase: This is a branching enzyme, it initiates formation of branches evolving from the main chain.
