I believe that is space i would check just to make sure tho
Answer:
K⁺ and HPO₄²⁻ ions are present in K₂HPO₄
Explanation:
K₂HPO₄ consist of anion and cation such as HPO₄²⁻ and K⁺. We can see that the charge on HPO₄²⁻ is negative 2. Thus inroder to balance the charge and to neutral the compound two potassium ions are attached because the charge on one atom of potassium is K⁺.
Properties of K₂HPO₄ :
It is salt of phosphoric acid.
Its density is 2.44 g/cm³.
It is odourless compound.
It is white powder and soluble in water.
It is used in fertilizer because it provide phosphorus which is beneficial for the growth of plants.
It is also used as a additive in food.
It is inorganic compound and also used as buffering agent.
There are many combinations because it is not all about the number of chemicals, but also about the size of the strand. The longer the strand the more combinations there are and more variations and various lengths provide various results.
Answer:
Oxygen is the limiting reactant.
Explanation:
Hello,
In this case, given the reaction:
Hence, given the masses of both ethanol and oxygen, we are able to compute the available moles ethanol by:
Next, we compute the moles of ethanol that react with the 0.640 grams of oxygen considering their 1:3 molar ratio in the chemical reaction:
In such a way, since there are 0.01 available moles of ethanol but just 0.0067 moles are reacting, we evidence ethanol is in excess, therefore the oxygen is the limiting reactant.
Best regards.
Boiling water- hot water rises from the bottom of the pan where it is initially heated and cooler water moves down to replace it, causing a circular motion.
