Answer:
1386g
Explanation:
Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.
if 14g dissolved in 100cm3
the amount that will dissolve in 1000cm3 = 14 x 1000/ 100
=1400g
To form a saturated solution, 1400 - 14 = 1386g must be added.
The answer is (4) synthesis. Synthesis reaction means that two or more reactants combine directly to one production. Substitution or single replacement means that one element of a compound is replaced by another element. Double replacement means that two ionic reactants exchange ions to form two new productions.
Answer:
Fe₃Si₇
Explanation:
In order to determine the empirical formula, we have to follow a series of steps.
Step 1: Determine the percent composition
Fe: 46.01%
Si: 53.99%
Step 2: Divide each percentage by the atomic mass of the element
Fe: 46.01/55.85 = 0.8238
Si: 53.99/28.09 = 1.922
Step 3: Divide all the numbers by the smallest one
Fe: 0.8238/0.8238 = 1
Si: 1.922/0.8238 = 2.33
Step 4: Multiply by numbers that make the coefficients whole.
Fe: 1 × 3 = 3
Si: 2.33 × 3 = 7
The empirical formula is Fe₃Si₇.
B. the tilt of the Earth on it's axis
The moon affects the tides by it's gravitational pull on Earth. So the moon has no affect on the earth's seasons. The distance from earth from the sun only affects the ability of Earth to sustain liquid water because earth is in something scientists like to call the "Goldilocks Zone" This has no affect on the seasons. However, the angle at which the sun's light hit the earth does effect seasonal changes and it's tilt does change.
