Chemistry

iris [78.8K]2 years ago
7 0

Answer:

Hot chocolate is as straightforward as drinks go: at its core, it's milk, cocoa powder, and sugar. Despite its simplicity, this cold-weather classic is swirling with science. The backbone of any decent hot chocolate is milk. Beyond water, milk is perhaps the most basic and familiar substance to humans.

What begins to happen to radioactive uranium as soon as a mineral containing it crystallizes from magma?
Aleonysh [2.5K]
<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>

Which is the limiting reactant if we start with 30.0 g Al and 30.0 h O2​
lorasvet [3.4K]

Al

Explanation:

The limiting reactant will be Al:

        4Al + 3O₂ → 2Al₂O₃

The limiting reactant is the reactant in short supply in a chemical reaction.

     Given parameters:

  Mass of Al = 30g  Molar mass = 27g/mol

         Number of moles = \frac{mass}{molar mass} =  \frac{30}{27}

         Number of moles of Al = 1.111 mole

  Mass of O₂ = 30g, molar mass = 32g/mol

   Number of moles =  \frac{30}{32} = 0.94mol

In the reaction:

          4 moles of Al reacted with 3 moles of O₂

         1.11moles of Al will require \frac{1.11 x3}{4} = 0.83mole to react

But we have been given 0.94mole of O₂. This is more than required.

Therefore O₂ is in excess and Al is the limiting reactant.

as any personal information of clients, customers, employees, guests, or anyone else exposed in the incident?
Elena L [17]

Answer:

"Protecting the privacy of your employees is critical to the long term success of your business. Senior leadership, high-profile executives and their families, as well as other customer-facing employees are particularly vulnerable to targeting to bad actors when their personal information is exposed. Other potential sources of danger include disgruntled employees, ex-employees and even customers."

Hope this helps :)

Explain why the production of a gas in this experiment is or is not different from the formation of water vapor in the heating c
den301095 [7]

The production of a gas is different because unlike the heating curve, there was no heat applied to this experiment, and the experiment was a chemical reaction.

<h3>What is a Heating curve?</h3>

This shows the relationship between the temperature of the heating system and the air temperature in the outer environment.

The chemical reaction emitted heat as against the other which involved heat application which is why water formation in this curve was different.
