Answer:
what is the net ionic equation
H2SO4(aq) + Cal2(aq) → CaSO4(s) + 2Hl(aq)?
A. H++ SO42- + Ca2+ + 21 → CaSO4 + H+ +1-
B. 2H+ + S042- + Ca2+ + 21° → Ca2+ + SO42- + 2H+ + 21
C. S042- + Ca2+ → CaSO4,
D. 2H+ + SO42- + Ca2+ + 2I- → CaSO4 + 2H+ + 2I-
cancel the spectator ion that is the ions which does not take place in the reaction
for this case is 2 H^+ and 2 i^-
Answer:
D.metals
Explanation:
The majority of elements in the periodic table are classified as metals.
Answer:
Increases.
Explanation:
Temperature is the measure of the average kinetic energy of a system. As temperature increases, so will kinetic energy. As kinetic energy increases, speed increases.
The answer is- The solubility of a given solute in a given solvent typically depends on temperature.
Dipole moment measures the polarity of the molecule that is measure of the separation of two opposite charges. Electronegativity difference between the atoms results dipole moment.
Dipole moment of bond is equal to the product of the magnitude of charge and distance between them (charges).
It is given by:
where,
= dipole moment
= magnitude of charge whether partially positive or negative charge.
= distance between charges.
Since, bond distance is larger than the bond distance, because of large partial charge on the atoms of ; from the definition of dipole moment (1.08) has smaller dipole moment than (1.82).
