The 4 second rule is used to estimate your total stopping distance under ideal conditions.
Answer:
E. temperature of the water
Explanation:
The independent variable is the variable that changes, and it's also the variable that the dependent variable's results depend on. So depending on the temperature of the water, results in the ice cubes height. So the independent variable is the temperature of the water.
The last answer, neither positive nor negative
The major ionic species present in aqueous solution of sodium sulfate is
2 Na+ and SO4^2-
<u><em>explanation</em></u>
When electrolyte dissolve in water they dissociate into ions.
There are two type of electrolyte that is strong and weak electrolyte.
Sodium sulfate is a strong electrolyte and therefore it dissociate completely into ions as below
Na2So4 → 2 Na+ (aq) + So4^2- (aq)
Answer:
2.178x10⁷kg, 2.178x10¹³mg, 2.178x10¹⁶μg, 2.178x10⁴ metric tons.
Explanation:
<em>The units are kg, μg, mg and metric tons (1metric ton = 1000kg)</em>
<em />
To solve this question we must convert, first, the grams to milligrams, and to kilograms. Then, the kilograms to metric tons and the milligrams to micrograms:
kg:
2.178x10¹⁰g * (1kg / 1000g) = 2.178x10⁷kg
mg:
2.178x10¹⁰g * (1000mg / 1g) = 2.178x10¹³mg
μg:
2.178x10¹³mg * (1000μg / 1mg) = 2.178x10¹⁶μg
metric tons:
2.178x10⁷kg * (1metric ton / 1000kg) = 2.178x10⁴ metric tons
