The international space station is equipped with a vika oxygen generator which uses the following reaction to generate oxygen. liclo subscript 4 space (s )space rightwards arrow licl space (s )space plus space 2 space straight o subscript 2 space (g )determine the mass (in kg) of liclo4 required to fill the 9.3x105 l interior volume of the international space station with oxygen at a pressure of 0.22 atm and a temperature of 22.2 ˚c. you may find the following molecular weights useful: liclo4 - 106.39 g/mol licl - 42.394 g/mol o2 - 31.9998 g/mol report your answer below. do not use scientific notation, or include units. if carmen adds zeros behind the decimal place in your answer, do not worry. your response will be graded correctly.

Which statement are accurate about snow flakes

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5

Which of these statements best explains why space exploration should be encouraged? it prepares humans to live without oxygen. it dispel myths about objects in space. it prevents comets and asteroids from striking earth. it creates technology to absorb harmful radiations in space.
