At room temperature the substance is at a temperature between melting point and boiling point. So it Will be a liquid. So the phase of a substance liquid gas or solid depends on their melting points, boiling points, room temperature and pressure.

Gases have covalent bonds and metals have ionic bonds.. Not sure about water
Edit: I looked it up, water has polar covalent bonds. Polar bonds are when electrons are shared unequally by the elements involved in the bond, so Hydrogen and Oxygen.

What is the ph of a buffer consisting of 0.200 m hc2h3o2 and 0.200 m kc2h3o2? the k a for hc2h3o2 is 1.8×10−5. view available hi
AURORKA [14]
PH = pKa + log \frac{[base]}{[Acid]}
Acid  is HC₂H₃O₂ and conjugate base is KC₂H₃O₂,
pKa = - log Ka = - log (1.8 x 10⁻⁵) = 4.74
so pH = 4.74 + log (0.2/0.2) = 4.74
This is called maximum buffer capacity (when acid conc. and base conc. are equal) the pH = pKa in this case

Ugo [173]
BaCl₂(aq) + Na₂SO₄(aq) = BaSO₄(s) + 2NaCl(aq)

Ba²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + SO₄²⁻(aq) = BaSO₄(s) + 2Na⁺(aq) + 2Cl⁻(aq)

Ba²⁺(aq) + SO₄²⁻(aq)= BaSO₄(s)

Answer:

C. 500 cm' of 1.0 mol dmº magnesium sulphate solution.

Explanation:

Let us look at each of the solutions individually;

CaCl2  has three particles

K2SO4 has three particles

MgSO4 has two particles

C2H5OH has only one particle

The number of moles of moles in 250 cm of 2.0 mol dm-3 potassium chloride is 250/1000 * 2 = 0.5 moles having two particles

Also; number of moles in 500 cm' of 1.0 mol dm-3 magnesium sulphate solution= 500/1000 * 1 = 0.5 moles having two particles
