Answer: 52.17%
Explanation:
Number of matches in the box = 46
Number of matches that lit on the first strike = 22
Number of matches that did not light on the first strike = 46 - 22 = 24
Therefore, the percentage of the matches in the box did not light on the first strike will be:
= (Number of matches that did not light on the first strike / Number of matches in the box) × 100
= 24/46 × 100
= 52.17%
Therefore, the percentage of the matches in the box that did not light on the first strike is 52.17%.
Answer:
A solution
Explanation:
The solute is the substance being dissolved by another substance
2.34E25 aka 25 0's behind the decimal
Answer:
1.98 M
Explanation:
Given data
- Initial volume (V₁): 93.2 mL
- Initial concentration (C₁): 2.03 M
- Volume of water added: 3.92 L
Step 1: Convert V₁ to liters
We will use the relationship 1 L = 1000 mL.
Step 2: Calculate the final volume (V₂)
The final volume is the sum of the initial volume and the volume of water.
Step 3: Calculate the final concentration (C₂)
We will use the dilution rule.
Cs and F
Explanation:
The two elements on the periodic table that would be most reactive would be Cesium and Florine.
Florine is the most electronegative and the most reactive non-metal on the periodic table. It has a small size and needs just one electron to complete its octet.
Cesium is the most electropositive non-metal. It requires just a loss of one electron to be stable and have complete octet.
Cs and F are the most electropositive and elecronegative elements on the periodic table of elements.
