Answer:

It uses fossils to help pinpoint the ages of rocks.

Explanation:

Radiocarbon dating can not be used to determine the age of rocks.

Carbon dating works well only for objects that are less than 50,000 years. Most rocks are far older than that. Over time, carbon-14 decays gradually into nitrogen. Hence, we can not really use radiocarbon dating to determine the absolute age of a rock sample since the carbon-14 in the fossils of ancient rock samples may have completely decayed.

Find the actual yield when the theatrical yield is 1.09g and percent yield is 90%.

ioda

Actual yield/Theoretical yield *100= Percentage yield. So Actual yield = Percentage yield*Theoretical yield.
Therefore actual yield= 90/100 * 1.09g = 0.98g

Actual yield: 0.98 g

Analyze complete and balance the following equation co2(g)+hcl(aq)

Anna007 [38]

Answer:

$CO_{2} (g)+4HCl(aq)->2H_{2} O(g)+CCl_{4} (g)$

This is a double displacement reaction, C goes with Cl in the products side and O2 goes with H. All that is left is to balance the equation, making sure each side has equal amounts of atoms.
