Answer:
C) quartz
Explanation:
Quartz is a common mineral. Also, quartz isn't a metallic substance. I'm hoping that this helps :)
Explanation:
To balance a chemical equation, there are so many approaches to solve the problem.
A balanced chemical equation is one that obeys the law of conservation of matter.
According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".
This implies implies that equal number of atoms must be on both sides of the equation.
There are two main approaches to balancing chemical equation;
- Inspection
- mathematical equation
We can inspect the equation and affix the proper coefficients to combining species.
Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:
For example:
H₂ + O₂ → H₂O
mathematically;
aH₂ + bO₂ → cH₂O
conserving:
H : 2a = 2c
O: 2b = c
let a = 1
c = 1
b = 
multiply by 2 to give;
a = 2, b = 1 , c= 2
2H₂ + O₂ → 2H₂O

The objects that are rubbed together will create charges among themselves due to friction.
(1) The balloon rubbed with a wool cloth will be charged.
(2) If she comb near a small, uncharged object nothing will change.
(3) This is a scientific investigation because it does not involved a step by step process to answer a scientific query.
1 mole = 70.9
X mole = 140
X=1.9746 moles
X= 1.98 when rounded to 3 significant figures.
Although lipids hold the majority of the body's energy reserves, glycogen is the body's primary energy source.
Glucose is a polymer that makes up glycogen. Our body's primary source of energy is carbs. The remaining glucose in the body is turned into glycogen and stored in various places, but the majority of our body's energy reserves are found in fats, which are kept in the form of lipids.
Where does the energy come from in the muscles?
The chemical energy that is stored in our meals is used by muscles to produce heat and motion energy (kinetic energy). Energy is necessary for maintaining body temperature, promoting physical activity, and enabling tissue growth and repair. Foods high in protein, fat, and carbohydrates provide energy.
What Takes Place to Muscles in the Absence of Glucose?
Your body converts carbs, such as those found in bread or fruit, into glucose after consumption. Glycogen is the form of glucose that is stored in your muscles and liver and is used for energy when you are not eating or while you are exercising.
