how do i balance this equation:
sodium hydroxide reacting with sulfurous acid [1 mol sulfurous acid reacts with 2 moles hydroxide ion]
my hydrogens aren't balancing right
2 NaOH + H2SO3 -> Na2SO3 + 2 H2O
ah thx, i accidently wrote H3O
Why are oxygen tanks and spacesuits needed to explore the moon?
Oxygen tanks and spacesuits are needed to explore the moon because the moon does not have a breathable atmosphere like Earth. Here's a brief explanation of why:
1. Atmosphere: The moon's atmosphere is extremely thin, almost negligible compared to Earth's atmosphere. It mainly consists of trace amounts of gases like helium, neon, and hydrogen. There is no significant amount of oxygen available naturally on the moon.
2. Lack of air pressure: The moon has no substantial air pressure, which means there is no force exerted by the gases present to avoid the boiling and subsequent evaporation of fluids, including our bodily fluids. Without a spacesuit, the low air pressure would cause boiling of bodily fluids, leading to immediate harm to our organs.
3. Temperature extremes: The moon experiences extreme temperature variations, ranging from extremely hot to extremely cold. In direct sunlight, surface temperatures can reach around 260 degrees Fahrenheit (127 degrees Celsius), while in darkness, the temperature can drop to approximately -280 degrees Fahrenheit (-173 degrees Celsius). Spacesuits provide insulation to protect astronauts from these extreme temperatures.
4. Life support: Spacesuits are designed to provide a controlled environment, including a supply of oxygen for breathing. They often have built-in oxygen tanks, which provide a continuous flow of breathable air. This ensures that astronauts can survive in the harsh lunar environment by having a stable supply of oxygen.
In summary, oxygen tanks and spacesuits are essential for lunar exploration because they provide a breathable atmosphere, protection from extreme temperatures, and supply the necessary oxygen for astronauts to survive in the moon's inhospitable conditions.
