How does heart failure affect the lungs?
o Carbon dioxide enters the lungs.
Too much oxygen enters the lungs.
Blood leaves the lungs.
o Fluid can build up in the lungs.
Answer:
Pulmonary oedema can be caused by lung disease, but when heart failure is more serious, the pressure of blood in the lungs builds-up, pushing fluid into the air sacs. This is how heart failure can lead to respiratory failure. People with pulmonary oedema will feel breathless, weak and unwell.

i n the notatation,5N2 what is the number of nitogen atoms
Answer:
10 nitrogens
Explanation:
The 2 is the number of nitrogens in a molecule of N2. There are 2 of them.
The 5 is a whole different critter. It tells you that it was part of an equation and it took 5 molecules of Nitrogen to balance the equation. You only see numbers to the right of a molecule when the molecule is in an equation.

Will lithium become a cation or anion?
Answer:
Lithium Cation is a monovalent cation that is metabolized much like sodium and is important in many cellular functions inside or on the surface of cells. lithium has a single valence electron that is easily given up to form a cation. Because of this, lithium is a good conductor of heat and electricity as well as a highly reactive element, though it is the least reactive of the alkali metals
what type of reaction is Pb + CuCl2 ---> PbCl2 + Cu

Question is in picture! Due at 3:45!!!
Copper is a product of the reaction that occurs when dry ammonia is passed over a sample of heated copper(II) oxide. The equation for the reaction is given below. 2NH3 + 3CuO --> 3Cu + 3H2O + N2 Calculate the mass of copper produced if 0.12 dm^3 of nitrogen is produced at room temperature and pressure (rtp). (Relative atomic mass of Cu = 64; One mole of gas occupies 24 dm3 at rtp
Answer:
0.12 dm^3 x (1 mol/24 dm^3) = ? mols N2
mols Cu = ? mols N2 x (3 mols Cu/1 mol N2) = ?
Then g Cu = mols Cu x atomic mass Cu = ?

Write a clear scientific explanation of how and why the water ended up on the mirror and not in the tub. Be sure to include scientific vocabulary (including any phase changes that occurred and the role of kinetic energy).
Vocabulary words-
Condensation
Gas
Heat
Kinetic energy
Liquid
Steam
Vaporization
Water vapor
Answer:
The water was hot it turned into steam then turned to water vapor and the got attached to the glass and as the gas got attached the glass and it built up then became water again. As the vaporization was happening the gas was moving hence the energy building up.

Balancee las ecuaciones químicas por el método de tanteo e identifique que tipo de reacción es: 1.1.- Cloruro férrico acuoso reacciona con carbonato de sodio sólido para formar carbonato férrico sólido y cloruro de sodio acuoso.
Respuesta:
2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + 6 NaCl(aq)
Explicación:
Consideremos la ecuación no balanceada que ocurre cuando cloruro férrico acuoso reacciona con carbonato de sodio sólido para formar carbonato férrico sólido y cloruro de sodio acuoso. Esta es una reacción de doble desplazamiento.
FeCl₃(aq) + Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)
Vamos a usar el método de tanteo. Empezaremos balanceando los átomos de C, multiplicando Na₂CO₃ por 3.
FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)
Luego, balancearemos los átomos de Fe, multiplicando FeCl₃ por 2.
2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)
Finalmente, obtendremos la ecuación balanceada, multiplicando NaCl por 6.
2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + 6 NaCl(aq)

Calculate the volume that 12.5 g of carbon dioxide gas will occupy at a temperature of 45 degrees Celsius and a pressure of 1.20 atm
Answer:
[tex]V=6.2L[/tex]
Explanation:
Hello there!
In this case, according to the given information, it is possible for us to realize that we need to use the ideal gas equation in order to calculate the volume of CO2 but firstly calculating the moles:
[tex]n=\frac{12.5g}{44.01g/mol}=0.284mol[/tex]
Then, we proceed with the ideal gas equation to solve for volume:
[tex]PV=nRT=\\\\V=\frac{nRT}{P}\\\\V=\frac{0.284mol*0.08206\frac{atm*L}{mol*K}*(45+273.15)K}{1.20atm}\\\\V=6.2L[/tex]
