Answer:

The rate of the reaction would be halved.

Explanation:

The reaction is first order with respect to reactant A and second order with respect to reactant B. The rate equation is [A][B]^2

If the concentration of A is doubled and the concentration of B is halved, rate = 2 × (1/2)^2 = 2 × 1/4 = 1/2.

The rate would be halved.

Which net ionic equation describes the reaction between K3PO4(aq) when it is mixed with Al(NO3)3(aq)?
Wittaler [7]
K₃PO₄<span>(aq) reacts with Al(NO</span>₃)₃(aq) and form AlPO₄(s) and KNO₃(aq) as the products. 

Before writing net ionic reaction, following steps should be followed.

Step 1 : Write the balanced chemical equation for the reaction and indicate the state of compound as aq,s,g or l.
      K₃PO₄(aq) + Al(NO₃)₃(aq) → AlPO₄(s) + 3KNO₃(aq) 

Step 2 : Identify the ionic species which dissolve in water to form ions.
K₃PO₄(aq) → 3K⁺(aq) + PO₄⁻(aq) 
Al(NO₃)₃(aq) → Al³⁺(aq) + 3NO₃⁻(aq) 
KNO₃(aq) → K⁺(aq) + NO₃⁻(aq)

Step 3 : Write the equation again by using ions.
3K⁺(aq) + PO₄⁻(aq) + Al³⁺(aq) + 3NO₃⁻(aq) → AlPO₄(s) +3K⁺(aq) + 3NO₃⁻(aq)

Step 4 : Identify the similar species in both side of the equation and cut off them.
3K⁺(aq) and 3NO₃⁻(aq) present in both sides. Hence, those ions can be cut off.

Step 5 : Get the final ionic equation.
The net ionic equation for the given reaction is 
      Al³⁺(aq) + PO₄⁻(aq) → AlPO₄(s)

Q3. Which of the following objects are chiral and which are achiral? a
Sergio039 [100]

Answer:

See explanation

Explanation:

In this question, we have to follow the IUPAC rules. Lets analyze each compound:

a. 1-methylbutane

In this compound we have a chain of 5 carbons, so the correct name is <u>Pentane.</u>

b. 1,1,3-trimethylhexane

In this compound, we longest chain is made of 7 carbons, so, we have to use the name "heptane". Carbon one would be the closet one to the methyl group, so the correct name is  <u>2,4-dimethylheptane.</u>

c. 5-octyne

In this case, carbon 1 would be the closet one to the triplet bond. With this in mind, the correct name is <u>oct-3-yne.</u>

d. 2-ethyl-1-propanol

In this compound, we longest chain is made of 4 carbons, so, we have to use the name "butane". Carbon one would be the carbon with the "OH" group, so the correct name is  <u>2-methylbutan-1-ol.</u>

<u>e. 2.2-dimethyl-3-butanol</u>

In this case, carbon 1 would be the closet one to the "OH". With this in mind, the correct name is <u>3,3-dimethylbutan-2-ol.</u>

See figure 1

I hope it helps!

A student is able to lift 500N weight by applying 100N. What is the mechanical advantage of a simple machine?
Semmy [17]

Explanation:

Load=500N

Effort=100N

Now,

We have,

Mechanical advantage= Load / effort

= 500/100

=5

Therefore, mechanical advantage is 5.
