In the reaction we gives the magnesium chloride and released hydrogen gas.

The reaction is carried out by contaning positive and negative charged on elements as follows

Mg + HCl --->MgCl2 + H2

Net reaction gives

Mg+ + 2Cl- + 2H+---> Mg+² + 2Cl- + 2H

Check it Mg(s) and Mg2+ not equal . The donor is element while the acceptor is an ion. The same process is done for H2 (g) and H+.

At 25°C, gas in a rigid cylinder with a movable piston has a volume of 145 mL and a pressure of 125 kPa. Then the gas is compres

natta225 [31]

Answer:

(4) 230 kPa

Explanation:

The temperature is constant, so the only variables are pressure and volume.

We can use Boyle’s Law.

$p_{1}V_{1} = p_{2}V_{2}$

Divide both sides of the equation by $V_{2}$ .

$p_{2} = p_{1} \times \frac{V_{1}}{ V_{2}}$

$p_{1} = \text{145 kPa}; V_{1} = \text{125 cm}^{3}}$

$p_{2} = ?; V_{2} = \text{80. cm}^{3}$

$p_{2} = \text{145 kPa} \times \frac{\text{125 cm}^{3}}{\text{80. cm}^{3}} = \textbf{230 kPa}$

there were may gaps for in discovered elements.After their discovery the got their proper place in table.
with the help of mendeleev periodic table , properties of several elements were studied correctly.

demerits of mendeleev periodic table

it could not arrange hydrogen as it shows the property of both alkali and halogens.
it could not arrange isotopes because they have different atomic weight but same atomic number.
it could not arrange Lanthanides and Actinides.

hope these points helped you

need more points then comment it .
