The volume of the nitrous oxide gas is 1729.3 Liters
<h3>What is the number of moles of gas present in 3.40 kg of nitrous oxide?</h3>
The number of moles of gas present in 3.40 kg of nitrous oxide is determined from the formula below:
Numbers of moles = mass/molar mass
the mass of nitrous oxide = 3.40 kg or 3400 g
the molar mass of nitrous oxide = 44.013 g/mol
Moles of gas = 3400 / 44.013
Moles of gas = 77.25 moles
Using the ideal gas equation to determine the volume of the gas:
PV= nRT
V = nRT/P
where;
- V is the volume of gas
- n is the number of moles of gas
- R is molar Gas constant = 0.082 L.atm/mol/K
- T is the temperature of the gas
V = 77.25 * 0.082 * 273 / 1
The volume of the gas = 1729.3 Liters

Answer:
Ionic.
Explanation:
Elements with higher electronegativity values are better at attracting electrons in a chemical bond.
- A chemical bond is considered "ionic" if the electronegativity difference between the two bonding atoms is greater than
. - Otherwise, this chemical bond is considered "covalent".
In this example, the difference between the electronegativity of oxygen and lithium is 
. Since 
, the bond between the two elements would likely be ionic.
It is possible to reach the same conclusion based on the fact that lithium is a metal while oxygen is a nonmetal. When metal elements react with non-metal elements, the product is typically an ionic compound- with ionic bonds between the atoms.
Gold is classified as a Solid
Answer:
a)beta decay; to reduce the number of neutrons
Explanation:
When an isotope decays by beta decay, a neutron is converted into a proton, an electron and a neutrino (a particle that serves to balance spins). This process reduces the neutron/proton ratio.
During the beta decay of carbon-14, an atom of 14C decays into an atom of 14N. Hence the number of protons in the atom increases by one, creating a nitrogen atom.
When a liquid absorbs heat energy without increasing its temperature is because it is using the absorbed heat for the change of phase from liquid to vapor. This is call vaporization. Vaporization requires energy because the molecules have to overcome the interaction that keeps them close to their neighbors in the liquid.So, <span>the answer is the option B.) it vaporizes.</span>
