Answer:
22.5 mL
Explanation:
We are given an amount of a fluid in a graduated cylinder and required to determine its volume.
Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.
The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL
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
<span>2CO(g) + 1O2(g) ---> 2CO2(g)
2 mol CO 1 mol O2 2 mol CO2
1 mole O2 to 2 moles CO2, or
</span>1 mole O2 : 2 moles CO2.
I believe it is D.
Since something with a high temperature has a higher kinetic energy, it would make sense for the energy of the molecules in the ground to increase. This is because the increasing temperature of the ground allows for the molecules to become faster in motion.
The six basic elements of weather include temperature, humidity, atmospheric pressure, wind, precipitation, and cloudiness.
