I found this on google

“The periodic table is important because its is organized to provide a great deal of information about elements and how they relate to one another in one-easy-to-use reference. The table can be used to predict the properties of elements, even those that have not been discovered.”

I hope this helps

When the following equation is balanced what is the coefficient for CaCI2? Ca (s) + 2HCI (aq) —> CaCI2 (aq) + H 2(g)
Allisa [31]

Hello!

The coefficients of any chemical compound are located in the front.

We are asked to find the coefficient of CaCl2 when the equation is balanced. Before finding the coefficient, we should determine if the equation is balanced or not.

Right side: 1 Ca, 2 H, 2 Cl

Left side: 1 Ca, 2 H, 2 Cl → This equation is balanced!

Since the compound CaCl2 has no number in from of the compound, the coefficient has to 1.

Therefore, the coefficient for CaCl2 is 1.

If kinetic energy increases does pressure decrease?
enyata [817]

If molecules are in a closed container then we expect the pressure to increase as the kinetic energy increases. This is because the atoms of an element collide with the walls of the container and increase the pressure.

If we use the formula PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R the ideal gas constant and T is the temperature.  According to the formula, P is directly proportional to temperature. An increase in temperature leads to an increase in pressure.

Since we know that temperature is the average kinetic energy of molecules present. It means as we increase the temperature we increase the kinetic energy of the molecules which in turn leads to an increase in the pressure.

Write the reaction that occurs when propyl methanoate is hydrolyzed in water and in NaOH
Free_Kalibri [48]

An ester , propyl methanoate ( HCOOC₃H₇) when reacts with sodium hydroxide( NaOH) forms sodium methanoate (HCOONa) as the main product and propanol (C₃H₇OH).

The reaction is as follows:

HCOOC₃H₇+NaOH ⇒HCOONa + C₃H₇OH

So when propyl methanoate is hydrolyzed in water and in NaOH then sodium methanoate (HCOONa) as the main product and propanol (C₃H₇OH) forms
