1) 2K(s) + 2H₂O(l)→ 2KOH(aq) + H₂<span>(g)
This is a single replacement reaction where K reacts with H</span>₂O , displaces the H⁺ ion in water and combines with OH⁻ to form a base.

2) 2B</span>i(NO₃)₃(aq) + 3H₂S(g)→ Bi₂S₃(s) + 6HNO₃<span>(aq)
</span>This is a double displacement reaction where the ions are exchanged and form new compounds. Since ions are exchanged between 2 compounds its called double displacement.
3) 2HNO₃<span>(aq) + Ba(OH)</span>₂<span> → Ba(NO</span>₃<span>)</span>₂<span>(aq) + 2H</span>₂O<span>(l)
This is an acid base reaction where nitric acid and barium hydroxide react to form the respective salt and water</span>
Water will have higher surface tension.
Explanation:
There are strong hydrogen bonds and strong intermolecular forces present in water. Water is polar in nature that is why surface tension is present in it. The force of attraction between the particles is the main factor for surface tension.
The cohesion force in the liquid causes surface tension.
Since the other substance is acetone which does not form strong intermolecular forces hence it has low value of surface tension. They have low cohesive forces and get stick to the surface and are spilled instead of attaining minimal volume.
<span>You are given O2 and C3H8, this is a combustion
reaction. The chemical reaction is C3H8 + 10O2 à 3CO2 + 4H2O. You are also given the molar mass
of O2 which is 32.00 g/mol and C3H8 which is 44.1 g/mol. You are required to
find the mass of O2 in grams. Since you have the reaction, oe mole of C3H8 is
required to completely react 10 moles of O2. So,</span>
0.025g C3H8(1 mol C3H8/44.1 g C3H8)(10 mol O2/1
mol C3H8)(32 g O2/1 mol O2) = <u>0.1802 g O2

Answer:
Molar mass of P₂O₅ = 141.948 g/mol which is approximately 142 g/mol.
Explanation:
Molar mass of AlCl₃
Molar mass = 26.982 + 35.5 × 3 = 133.32 g/mol
Molar mass of BaCl₂
Molar mass = 137.33 + 35.5 × 2 = 208.33 g/mol
Molar mass of MgCl₂
Molar mass = 24.305 + 35.5×2 = 95.305 g/mol
Molar mass of P₂O₅
Molar mass = 30.974×2 + 16× 5 = 141.948 g/mol
LMBO, for science.
Answer:
<em>The increase in kinetic energy leads to leakage of water from the syringe. When the outside temperature is more than the liquid temperature, say the syringe is out in sunshine, then the liquid becomes slightly warmer.</em>
