Fill in the blank with the correct answer. The longer the handle the __________ the mechanical advantage and the greater the inc

ASHA 777 [7]

Answer:

Greater

Explanation:

The longer the handle, the greater the mechanical advantage and the greater the increase in force that is applied to the bolt.

Mechanical advantage is the rate at which force is multiplied.

It simply compares the output force to the input force.
M.A is the force increasing tendency of a tool.
The longer the handle, the more the mechanical advantage and the lesser the applied force.

Use the equation editor or "Insert Chemistry - WIRIS editor" to write the balanced molecular chemical equation for the reaction

11Alexandr11 [23.1K]

Answer:

<u>Balanced equation:</u>

$Pb(NO_{3})_{2}(aq)+K_{2}CO_{3}(aq)\rightarrow PbCO_{3}(s)+2KNO_{3}(aq)$

Explanation:

The chemical reaction between Lead(II) Nitrate and potassium carbonate is as follows.

$Lead(II)Nitrate+Potassium\,carbonate \rightarrow Lead(III)\,\,carbonate+Potassium\,nitrate$

$Pb(NO_{3})_{2}(aq)+K_{2}CO_{3}(aq)\rightarrow PbCO_{3}(s)+2KNO_{3}(aq)$

<u>Ionic equation:</u>

$Pb^{2+}(aq)+2NO_{3}^{-}(aq)+2K^{+}(aq)+CO_{3}^{2-}(aq)\Leftrightarrow PbCO_{3}(s)+K^{+}(aq)+2NO_{3}^{-}$

Cancel the same ions on the both sides of the reaction.

The net ionic equation is as follows.

$Pb^{2+}(aq)+CO_{3}^{2-}(aq)\Leftrightarrow PbCO_{3}(s)$

A cylinder of compressed gas has a volume of 350 ml and a pressure of 931 torr. What volume in Liters would the gas occupy if al

hodyreva [135]

Answer:

$0.384\ \text{L}$

Explanation:

$P_1$ = Initial pressure = 931 torr = $931\times \dfrac{101.325}{760}=124.12\ \text{kPa}$

$P_2$ = Final pressure = 113 kPa

$V_1$ = Initial volume = 350 mL

$V_2$ = Final volume

From the Boyle's law we have

$P_1V_1=P_2V_2\\\Rightarrow V_2=\dfrac{P_1V_1}{P_2}\\\Rightarrow V_2=\dfrac{124.12\times 350}{113}\\\Rightarrow V_2=384.44\ \text{mL}=0.384\ \text{L}$

The volume the gas would occupy is $0.384\ \text{L}$ .

Compound A melts at 801o C and is soluble

Karo-lina-s [1.5K]

Explanation:

Organic compounds are defined as the compounds which contain carbon as their main element. For example, $CH_{3}OH$ is an organic compound.

Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.

As compound A melts at $801^{o}C$ and is soluble in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.

Whereas compound B melts at $24^{o}C$ and is insoluble in water. This means that this compound has covalent bonding and it is also non-polar in nature . Hence, it is more likely to be organic in nature.

Thus, we can conclude that compound B is more likely to be an organic

compound.
