Because the Hydrogen and Oxygen have a slight positive and negative charges that attract them to each other. As to why they bond in that ratio is because they're balanced that way, their electrons balance their covalent bond. This ratio of two Hydrogen and one Oxygen is well balanced therefore easily formed
An ionic compound is any compound containing a metal and a nonmetal
For example: NaCl, MgO, etc
Sometimes they’ll include polyatomic ions, such as CN (cyanide), ClO3 (chlorate), and many others
For example: NaCN, LiClO3, etc
A covalent or molecular compound usually contains shared pairs of electrons
Some examples are H2O, CO2, CHCl3
Notice, that these are all composed of non-metals.
Hope this helps. It’s hard to answer specifically when I can’t see the options.
If this helps, give me a brainliest, so I know I was helpful.
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
When the breakdown products from the digestion of food find their way into the cell, a series of chemical reactions occur in the cytoplasm. This allows some of the energy locked up in these products to be released and incorporated into the universal energy supplier in cells known as ATP (adenosine triphosphate).
Answer:
K⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻ (aq) → KCl (aq) + H⁺ (aq) + F⁻ (aq)
Explanation:
KF (aq) + HCl (aq) → KCl (aq) + HF (aq)
KF (aq) → K⁺ (aq) + F⁻ (aq)
HCl (aq) → H⁺ (aq) + Cl⁻ (aq)
KCl (aq) → K⁺ (aq) + Cl⁻ (aq)
HF (aq) → H⁺ (aq) + F⁻ (aq)
Just use the equation M=DV which means Mass equals Density times Volume. Simply plug your values into the equation to get
M=.789(139) and solve
