Answer:

**Answer:**

*(Incomplete question)*

Assuming the molarity of the weak acid is 17.4 M, the answer would be **52.4mL.**

**Explanation:**

Equivalence point is defined as the point where moles of titrant = moles of titrand (analyte).

At equivalence point,

# moles of NaOH = # moles of weak acid

# moles of NaOH = 0.1236 × 12.43 mL

= 0.1236 mol/L × 0.01242 L

= 0.00153511 moles of NaOH

= 0.00153511 moles of weak acid.

*Since the concentration of acid is not stated in your question, we will assume the concentration of the acid to be 17.4 M.*

concentration = no. of moles ÷ volume

⇒ vol. = no. of moles ÷ conc.

= 0.00153511 mol ÷ 17.4 mol/L

= 0.0267 L ≈ 26.7 mL

This means that the ** total volume** of the solution at the half equivalence point will be:

26.7 mL + 26.7 ml

=__ 52.4 mL. __

*N.B: Confirm missing variable from question: it could be concentration or volume of acid,but it is impossible to have two unknowns. Also, incase its pH of acid that's given, you can solve problem using Henderson-Hasslebauch equation.*

What is the speed of a basketball that is thrown 18meters in 4 seconds?

An insulated container contains 0.3 kg of water at 20 degrees C. An alloy with a mass of 0.090 kg and an initial temperature of 55 degrees C is mixed with the water in the insulated container. When thermal equilibrium is reached, the temperature of the mixture is 25 degrees C. Assume that heat flows only between the alloy and the water. What is the specific heat of the alloy?

What is the charge of the most stable ion of bromine?

Consider the following reaction: 2NO(g)+O2(g)→2NO2(g) Estimate ΔG∘ for this reaction at each of the following temperatures and predict whether or not the reaction will be spontaneous. (Assume that ΔH∘ and ΔS∘ do not change too much within the give temperature range.) 718k

**Answer:**

65 mg

**Explanation:**

We are given the dosage per pound but have the weight of the dog in kilograms, thus we should convert the 29.5 kg to punds ( 1 pound = 0.454 kg):

29.5 kg x 1 lb / 0.454 kg = 64.7 lbs

So now can answer our question:

( 1 mg / lb ) x 64.7 lb = 64.7

rounding to 65 mg

To treat itchy skin in a dog that weighs 29.5 kg, the dog should be given 65 mg of Benadryl.

To calculate the mass of **Benadryl** to give to a dog that weighs 29.5 kg, we need to use the recommended dosage of 1 mg per pound. First, we **convert** the weight of the dog from kg to pounds by multiplying it by 2.2046. So, the weight of the dog is approximately 65 pounds. To find the mass of Benadryl, we multiply the weight of the dog in pounds by the recommended dosage. Therefore, the dog should be given 65 mg of Benadryl.

Answer:

A. 1 J=1kg•m^2/s^2

Explanation:

Energy refers to the capacity to do work. According to the International System of units (SI units), energy is measured in Joules.

Energy is represented by the force applied over a distance. Force is measured in Newton (N) and distance in metres (m). Hence, energy is Newton × metre (N.m)

Newton is derived from the SI units of mass (Kilograms), and acceleration (metres per seconds^2) i.e Kg.m/s^2, since Force = mass × acceleration.

Since; Energy = Newton × metres

If Newton = Kg.m/s^2 and metres = m

Energy (J) will therefore be; Kg.m/s^2 × m

1J = Kg.m^2/s^2
