Equation for the reaction of sulfur dioxide with water
SO2 + H2O = reversible reaction = H2SO3
Reaction equation of sulfur dioxide and iodine water
SO2+I2+2H2O=H2SO4+2HI
The literal expression of the interaction between sodium and water
It's wrong
It should be: sodium + water = sodium hydroxide + hydrogen. Sodium strengthens the Oh of water to form NaOH. There is another h to form H2
2Na+2H2O=2NaOH+H2
Sodium reacts with water to produce hydrogen and sodium hydroxide?
Sodium + water = sodium hydroxide + hydrogen
What is the formula for calculating the surface area of cuboid and cube, and how to deduce it?
Cuboid surface area = 2 × (L × W + L × H + W × h)
Surface area of cube = 6 × edge length × edge length
How to cube round trees
For example, a tree is one meter long and 0.5 meters in diameter. How can we calculate the cube
First calculate the area of the bottom circle and multiply it by the height
How does the cubic formula work? Round, square and rectangular?
It's the bottom area times the height
Which is the cubic formula of a circle?
Is it the volume of a sphere/
V=3/4(∏R3)
Halo, I can't get it out. Anyway, it's four-thirds Π times r cube
