You need a weighing balance to weigh out 2g of solid sodium bicarbonate and a measuring cylinder to measure out 50 mL of water. You need to ensure that you use a facemask during the experiment.
<h3>How do we carry out the experiment?</h3>
We know that we require apparatus to carry out a scientific experiment. The apparatus are those things that would help us to carry out the experiment that we want to do.
In this case, the activity is to mix 2 g of sodium bicarbonate with 50 ml of distilled water and then mix the solution. You need a weighing balance to weigh out 2g of solid sodium bicarbonate and a measuring cylinder to measure out 50 mL of water.

Answer:
253.585 square inches
Explanation:
The figure can be decomposed into 2 rectangles and a quarter circle.
Area of the figure = area of rectangle 1 + area of rectangle 2 + area of ¼(circle)
✔️Area of rectangle 1 = Length × width
Length = 10 in
Width = 6 in
Area of rectangle 1 = 10*6 = 60 in²
✔️Area of rectangle 2 = Length × width
Length = 10 in
Width = 6 + 7 = 13 in
Area of rectangle 2 = 10*13 = 130 in²
✔️Area of ¼(circle) = ¼(πr²)
r = 9 in
π = 3.14
Area of ¼(circle) = ¼(3.14*9²) = 63.585 in²
✅Area of the figure = 60 + 130 + 63.585 = 253.585 square inches
