The number 23.0702 has 6 significant figures.
To answer this, you must have the rules for significant figures,
1. All non-zero numbers ARE significant
2. Zeros between two non-zero digits ARE significant
3. Leading zeros are NOT significant
4. Trailing zeros are ONLY significant if the number has a decimal point
The number 23.0702 has 4 non-zero numbers(rule 1), and both zeros are between two non-zero digits(rule 2). Since all 6 figures in the number 23.0702 are significant, the number 23.0702 has 6 significant figures.
Answer:
The sound wave travelled more quickly through the glass of water than the metal pole.
The sound wave travelled the fastest through the helium.
The sound wave travelled the slowest through the metal pole.
These 3 are most likely true.
<u>If you have to </u><u>pick</u><u> </u><u>just</u><u> </u><u>one</u><u>,</u> the sound wave travelled the fastest through the helium.
In a balanced chemical equation, the numbers of individual particles and the numbers of moles of particles are represented by the COEFFICIENTS.

Image result for What happens to sodium chloride when it dissolves in water
Explanation: On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms
Answer:
<em>When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.</em>
