Answer:
C. 64
Explanation:
Given:
The number of equally likely sample outcomes of a single stage = 4
Unknown:
Total number of elements if there are three stages= ?
Solution;
Probability is the likelihood of an event to occur.
In this problem;
For a single stage, the likely outcome is 4
So therefore;
For the 3 stages 4 x 4 x 4 = 64
Therefore, the total number of elements in the sample space of an experiment with 3 stages is 64
Answer:
Volume of the bar=10 X 4 X 5=200 cm^3
Mass=200 X 19.3=3,860 grams
Mass=3.86 Kilograms
Explanation:
A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. The characteristics of plasmas are significantly different from those of ordinary neutral gases so that plasmas are considered a distinct "fourth state of matter
Salt and water is formed as product, when Arrhenius acid and Arrhenius base reacts and the reaction is known as neutralization reaction.
<h3>
What is Arrhenius acid-base reaction?</h3>
- The concept of acid and base based on the theory of ionization which was first proposed in 1884 by Svante Arrhenius
- According to Arrhenius, on dissociation in water the hydrogen-containing compounds which give H+ ions or protons are the acids and the hydroxide compounds which give OH− ions on dissociation in water are bases.
- This theory is applicable only to compounds which are dissolved in aqueous solution.

Quartz has the formula SiO2
From the periodic table:
mass of oxygen = 16 grams
mass of silicon = 28.0855 grams
Mass of one mole of quarts = 28.0855 + 2(16) = 60.0855 grams
number of moles = mass / molar mass
number of moles = 1.6 / 60.0855 = 0.0266 moles
Each mole of quartz contains Avogadro's number of atoms.
Therefore:
number of atoms in 1.6 g = 1.6 x 6.02 x 10^23 = 1.603 x 10^22 atoms
