Which of the following information is necessary to describe an object's motion?

Zepler [3.9K]

Answer: The correct option is B.

Explanation: To describe the motion of an object, we use the equations of motion.

$v=u+at$
$s=ut+\frac{1}{2}at^2$
$2as=v^2-u^2$

From the above equations, we require position, speed and direction through which we an calculate the displacement, velocity and acceleration.

To calculate the complete motion of an object, we require all the three factors.

Hence, the correct option is B.

Which equation is used to help form the combined gas law? mc009-1. Jpg mc009-2. Jpg mc009-3. Jpg mc009-4. Jpg.

Luba_88 [7]

The combined gas law equation has been $\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$ .

The combined gas law has been assigned to the ideal gas. It has been stating that ideal gas are having negligible inter-molecular attraction and collision resulting in the absence of pressure and volume from the particles.

In an ideal gas the equation has been given as:

$PV=nRT$

Where, P has been the pressure of the gas

V has been the volume of the gas

n has been the moles of the gas

R has been a constant

T has been the temperature of the gas

The combined gas law has been given as the change in the pressure, and volume for a gas. It has been given as:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

2koh+bacl2>2kcl+Ba(OH)2 what is the net ionic.I know all hydroxides are insolubles except with group 1A ,I presumed Ba(Oh)2 i

Triss [41]

Answer:

$\boxed{\text{No reaction}}$

Explanation:

1. "Molecular" equation

$\rm 2KOH+ BaCl$_{2}$ \longrightarrow \, $ 2KCl + Ba(OH)$_{2}$$

Solubility rules

Salts containing Group 1 elements are soluble.
Salts containing halides are generally soluble, except the halides of silver, mercury(I), and lead.
All metallic hydroxides are insoluble except Group 2 from calcium down. So, BaCl₂ is soluble, and the molecular equation is

$\rm 2KOH(aq)+ BaCl$_{2}$(aq) \longrightarrow \, $ 2KCl(aq) + Ba(OH)$_{2}$(aq)$

2. Ionic equation

$\rm 2K$^{+}$(aq) + 2OH$^{-}$(aq)+ Ba$^{2+}$(aq) + 2Cl$^{-}$(aq) \longrightarrow \, $ 2K$^{+}$(aq)+ 2Cl$^{-}$(aq) + Ba$^{2+}$(aq) + 2OH$^{-}$(aq)$

3. Net ionic equation

$\rm 2K$^{+}$(aq) + 2OH$^{-}$(aq)+ Ba$^{2+}$(aq) + 2Cl$^{-}$(aq) \longrightarrow \, $ 2K$^{+}$(aq)+ 2Cl$^{-}$(aq) + Ba$^{2+}$(aq) + 2OH$^{-}$(aq)$

Cancel all ions that appear on both sides of the reaction arrow (in boldface).

$\textbf{2K$^{+}$(aq) + 2OH$^{-}$(aq) + Ba$^{2+}$(aq) + 2Cl$^{-}$(aq)}\\\longrightarrow \,\textbf{2K$^{+}$(aq)+ 2Cl$^{-}$(aq) + Ba$^{2+}$(aq) + 2OH$^{-}$(aq)}\\\text{Everything cancels. There is no net ionic equation.}\\\text{(nothing)} \longrightarrow \, \text{(nothing)}\\\text{Answer: }\boxed{\textbf{No reaction}}$
