Answer:
C.) 1345.5 J
Explanation:
To find the energy, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy (J)
-----> m = mass (g)
-----> c = specific heat (J/g°C)
-----> ΔT = change in temperature (°C)
The specific heat of aluminum is 0.89 J/g°C. You can plug the given values into the equation and solve.
Q = mcΔT
Q = (150 g)(0.89 J/g°C)(10 °C)
Q = 1335
*It is up to you whether you wish to trust this answer. My answer may be slightly different due to using a different specific heat.
Answer:
Kinetic energy is the energy of the motion of objects that are attached together.
Answer:
Cd(s) + AgNO₃(aq) → Cd(NO₃)₂ (aq) + Ag(s)
Oxidized: Cd
Reduced: Ag
Explanation:
Cd(s) + AgNO₃(aq) → Cd(NO₃)₂ (aq) + Ag(s)
Cd → Cd²⁺ + 2e⁻ Half reaction oxidation
1e⁻ + Ag⁺ → Ag Half reaction reduction
Ag changed oxidation number from +1 to 0
Cd changed oxidation number from 0 to +2
Let's ballance the electrons
( Cd → Cd²⁺ + 2e⁻ ) .1
( 1e⁻ + Ag⁺ → Ag ) .2
Cd + 2e⁻ + 2Ag⁺ → 2Ag + Cd²⁺ + 2e⁻
Finally the ballance equation is:
Cd(s) + 2AgNO₃(aq) → Cd(NO₃)₂ (aq) + 2Ag(s)
the three categories of atomic solids are as follows;
E. nonbonding atomic solids.
A. network covalent.
What are atomic solids?
Atoms of an element must be bonded to other atoms of the same atom type in order for a substance to be considered an atomic solid.
Diamond, silicon crystals, and pure metals are a few examples of atomic solids. Network solids are atomic solids in which the atoms are covalently connected to one another.
SiO2, often known as quartz, is another example of a network solid and is an extremely hard substance, scoring 7.5 out of 10.

Answer:
a. Both glycogen phosphorylase and glycogen synthase are phosphorylated
Explanation:
Glycogenesis is the process of glycogen synthesis while glycogenolysis is the process of glycogen breakdown.
They both hold a reciprocal relationship between them and the factors which enhance the rate of one, inhibit the other.
The main forms of the control is varied phosphorylation of the enzyme, glycogen synthase and enzyme, glycogen phosphorylase by the protein kinase A .
<u>On phosphorylation, Phosphorylated glycogen synthase is inactive while glycogen phosphorylase is activate.</u>
During fast state, glucose is required by the body which is provided by the process of glycogenolysis and thus phosphorylation will help to regulate the process.
