Is the following equation balanced? 2na + 2h2o = 2naoh + h2

yes

no

Yes

Explanation:

2Na + 2H2O → 2NaOH + H2

A chemical equation is balanced if the number of atom of elements on the reactant side is equal to the number of atom of elements on the product sides.

According to the equation above the chemical equation is balanced .From the equation 2 moles of sodium reacted with 2 moles of water to form 2 moles of sodium hydroxide and hydrogen gas.

On the reactant side(left side), the sodium has 2 atom of sodium and the water molecule has 4 atom of hydrogen and 2 atom of oxygen.

On the product side(product side), the sodium hydroxide compound have 2 atom of sodium , 2 atoms of oxygen and 2 atoms of hydrogen . The hydrogen gas has 2 atoms of hydrogen. Adding the hydrogen atom on the product side will give you 4 atoms of hydrogen.

From the illustration above you could notice the equation is balanced.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
