Answer:

law of conservation of mass
law of definite proportion
Avogadro's law

Explanation:

Law of conservation of mass ⇒ it states that matter can neither be created or destroyed.In a reaction the energy and the mass remain constant

Law of definite proportion ⇒ it states that samples of compounds will always contain the same proportion of elements by mass.proportion of elements by weight will always remain the same;meaning that percent by weight in elements will remain the same regardless of origin and quantity

Avogadro's law ⇒ it sates that under the same conditions of pressure and temperature, equal volumes of all gases contain the same number of molecules.if there is 500 ml of carbon and oxygen, they will have the same molecules if exposed to the same pressure and teprature level

Hope this helps,and if it helps mark as branliest thx

1. Mg2+ and Ca2+ are in the same group on the periodic table. In terms of electronic

finlep [7]

Answer:

Se detailed explanation.

Explanation:

Hello,

In this case, since both magnesium and calcium ions are in group IIA, we can review the following similar properties:

- Since both calcium and magnesium are in group IIA they have two valence electrons, it means that the both of them have two electrons at their outer shells.

- They are highly soluble in water when forming ionic bonds with nonmetals such as those belonging to halogens and oxygen's family.

- Calcium has 18 electrons and magnesium 10 which are two less than the total protons (20 and 12 respectively) since the both of them have lost two electrons due their ionized form.

- Their electron configurations are:

$Ca^{20}=1s^2,2s^2,2p^6,3s^3,3p^6,4s^2\\\\Mg^{12}=1s^2,2s^2,2p^6,3s^2$

It means that the both of them are at the $s$ region since it is the last subshell at which their electrons are.

Best regards.

If an ideal gas has a pressure of 4.03 atm,

kkurt [141]

Answer:

PV=nRT where P=pressure in atm, V=volume is liters, n=numbber of moles, R=gas constant, 0.08206 L-atm/mole KL, and T=temperature in K (273 + C). So (5.67atm)(99.39L)=n(0.08206 L-atm/mol.K)(328.94K), solve for n, the number of moles, n=20.9 moles.

vodka [1.7K]

Answer:

Rayon is a synthetic fiber or man-made fiber or artificial fiber as it is prepared from the natural raw material called cellulose. ... The kind of rayon fibers which imitate the feel and texture of natural silk is therefore termed as 'artificial silk'.

What is the effect of adding heat to a gas at constant pressure?

Anna007 [38]

The pressure will continue to build up eventually causing a release of pressure or an explosion.
