The equation shows lead reacting with sulfuric acid to produce lead sulfate and hydrogen gas.

upper p b (s) plus upper h subscript 2 upper s upper o subscript 4 (a q) right arrow upper p b upper s upper o subscript 4 (s) plus upper h subscript 2 (g).

which type of chemical reaction does this equation represent?
synthesis
decomposition
single replacement
double replacement

single replacement

Explanation: metals higher than hydrogen in the activity series will always displaced or replace hydrogen in a solution. Pb is higher than hydrogen in the activity series, so it will displaces or replace hydrogen in a solution

single replacement

Explanation:

a) Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.

b) Decomposition reaction is a type of chemical reaction in which one reactant give two or more than two products.

c) A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

d) A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
