Answer:
The mass of copper sulfate in 25 cm³ of the copper sulfate solution is 0.45 g
Explanation:
The given parameters are;
The volume of the copper sulfate solution = 100 cm³
The mass of the copper sulfate in the solution = 1.8 g
Therefore, the mass of copper sulfate in 25 cm³ of the solution is given as follows;
The mass of copper sulfate in 100 cm³ of the solution = 1.8 g
The mass of copper sulfate in 1 cm³ of the solution = 1.8 g/100 = 0.018 g
Therefore;
The mass of copper sulfate in 25 × 1 = 25 cm³ of the solution, m = 25×0.018 g = 0.45 g
∴ The mass of copper sulfate in 25 cm³ of the solution, m = 0.45 g
When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation. Precipitation occurs in a variety of forms; hail, rain, freezing rain, sleet or snow.
When the temperature is too hot for snow it'll rain and if the tempature is too cold it will freeze the rain and that's how you get snow or hail.
Hope this helped :)
Have a great day
They are pretty much the cause and effect. The independent variable that is being changed in the experiment, so it is the cause. The dependant variable is the result of change the independant variable, so the effect.
Answer:
1,171 fluid ounces of herbicide is sufficient for 2050 square meter.
Explanation:
If 300 square feet of land is sprayed by the herbicide at the rate of 16 liquid ounce, So 1,171 fluid ounces of herbicide is enough to cover the area of 2050 square meters.
Calculation:
First convert 300 square feet into meter which is equal to 28 square meter.
16 ounces of herbicide = 28 square meter
x ounces of herbicide = 1050 square meter
by cross multiplication we get
28 x = 16 x 1050
x = 32800/ 28
x = 1171 ounces of herbicide.
