3. How many moles of carbon dioxide gas, CO2, are there in 2.8 L of this gas at STP?

Chemistry
1 answer:
kenny6666 [7]3 years ago
5 0

Answer:

The answer is: 0,13 moles of CO2

Explanation:

We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273K of temperature:

PV=nRT n=PV/RT

n=1 atm x 2,8 L/ 0,082 l atm/K mol x 273K

n= 0,125078173 mol

If during an experiment zinc was found to be more reactive than lead or copper, zinc would be considered the strongest _____.

Zinc would be considered the strongest reducing agent.

<h3>Reducing agent</h3>

A reducing agent is a chemical species that "donates" one electron to another chemical species in chemistry (called the oxidizing agent, oxidant, oxidizer, or electron acceptor). Earth metals, formic acid, oxalic acid, and sulfite compounds are a few examples of common reducing agents.

Reducers have excess electrons (i.e., they are already reduced) in their pre-reaction states, whereas oxidizers do not. Usually, a reducing agent is in one of the lowest oxidation states it can be in. The oxidation state of the oxidizer drops while the oxidizer's oxidation state, which measures the amount of electron loss, increases. The agent in a redox process whose oxidation state rises, which "loses/donates electrons," which "oxidizes," and which "reduces" is known as the reducer or reducing agent.

What is the weight in grams of 3.36 × 10Ƴ molecules of copper sulfate (CuSOÁ)?
spin [16.1K]
Molar mass ( CuSO₄) = 159.609 g/mol

159.609 g ----------------- 6.02 x 10²³ molecules
         ? g ------------------ 3.36 x 10²³ molecules

mass = ( 3.36 x10²³) x 159.609 / 6.02 x 10²³

mass = 5.36 x 10²⁴ / 6.02 x 10²³

mass = 8.90 g

Please Explain. Why does salt water boil at a lower temperature than tap water?
nexus9112 [7]
We observe that heat capacity of salted water we will find that it is less than pure water. We now that it takes less energy to increase the temperature of the salt water 1°C than pure water. Which means that the salted water heats up faster and eventually reaches to its boiling point first.
