Its False, because in the formation of an ionic compound, an atom gains or loses an electron.
b. N₂O₃
c. NO₂
d. NO
e. N2₂O
(2) HClO2 (gram-formula mass = 68 g/mol)
(3) HClO3 (gram-formula mass = 84 g/mol)
(4) HClO4 (gram-formula mass = 100. g/mol)
The percentage mass composition of chlorine in HClO₃ is 42%.
Percentage mas of chlorine is calculated as follows:
atomic mass of chlorine = 35.5
(1) In HClO (gram-formula mass = 52 g/mol)
Percentage mass composition = 35 * 100% / 52 = 67.3%
(2) In HClO2 (gram-formula mass = 68 g/mol)
Percentage mass composition = 35 * 100%/68 = 51.4%
(3) HClO3 (gram-formula mass = 84 g/mol)
Percentage mass composition = 35 * 100% / 84 = 42%
(4) HClO4 (gram-formula mass = 100. g/mol)
Percentage mass composition = 35 * 100% / 100 = 35.5%
Therefore, the percentage mass composition of chlorine in HClO₃ is 42%.

None of the compounds have a percent composition of chlorine equal to 42%.
To find the compound with a percent composition of chlorine equal to 42%, we calculate the mass of chlorine in each compound and calculate the percent composition. Let's go through each option:
None of the compounds have a percent composition of chlorine equal to 42%. The correct answer is none of the above.

B. A 2 kg pot at 120°C
C. A 5kg pot at 25°C
D. A 2 kg pot at 25°C
The 2 kg pot at 25°C has the least thermal energy because it has both a smaller mass and a lower temperature than the other options.
The thermal energy of an object is related to both its mass and its temperature. In this case, we are considering iron pots of different masses and temperatures. Given the options, the 2 kg pot at 25°C would have the least thermal energy. This is because it has both a smaller mass and a lower temperature than all the other options listed.
The thermal energy is calculated by multiplying the mass, specific heat, and change in temperature. An object with a smaller mass and lower temperature would therefore have less thermal energy.

Answer: D. A 2 kg pot at 25C.
Explanation:
Answer:
Prone to storm damage and limited to particular areas of the ocean
Explanation:
Hello,
Even when the wave power is beneficent towards the environment care, it has a notable disadvantage when high energy waves are took by the energy stations by cause of electrical failures which lead to the station breakdown. On the other hand, there are hard-to-access areas in the ocean which restricts the enforcement of this type of energy.
Best regards.
