1. Write in 4 ways the formation of Mg3(PO4)2. ( I think it goes like this: acid + base --》salt and water, metal + nonmetal --》salt, metal + acid --》salt and hydrogen...) 2. What are the concentrations of Na(+) and SO4(2-) ion in a solution containing 1.42g of dissolved Na2SO4 in 500ml, assuming the dissociation is complete.​

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
