Hey there!:

density = mass / volume

1.84 g/mL =  12 g / V

V =  12 / 1.84

V = 6.521 mL

hope this helps!

[H_{3}O^{+}] = 0.00770 M

The equilibrium equation representing the dissociation of FCH_{2}COOH

FCH_{2}COOH(aq) + H_{2}O (l)    FCH_{2}COO^{-}(aq)+ H_{3}O^{+}(aq)

Given [H_{3}O^{+}] = 0.00770 M

Let the initial concentration of acid be x and change y

So y = [H_{3}O^{+}] =[FCH_{2}COO^{-}] = 0.00770 M

pK_{a} = 2.59K_{a} = 10^{-2.59}   = 0.00257 M

K_{a} = \frac{(0.00770 M)(0.00770 M)}{x - 0.00770}

0.00257 = \frac{0.00005929}{x - 0.00770}

0.00257 x - 0.00001979 = 0.00005929

x = 0.031 M

Therefore, initial concentration of the weak acid is <u>0.031 M</u>

why I which activity would stimulate the human immune system to provide protection against an invasion by a microbe
Andrei [34K]

The question is incomplete as it does not have the options which are:

(1) receiving antibiotic injections after surgery

(2) choosing a well-balanced diet and following it throughout life

(3) being vaccinated against chicken pox

(4) receiving hormones contained in mothers milk while nursing

Answer:

Being vaccinated against chicken pox

Explanation:

Vaccination is the procedure of giving the disease-causing germs which could be virus and bacteria in their dead or weakened state, some toxin, some proteins or some other molecules called a vaccine.

The benefit of providing vaccination is that the provided pathogen acts as an antigen and triggers the proactive immune response against the pathogen which helps in eradicating the main pathogen that has invaded the body.  The vaccination is used to treat the disease like chickenpox, measles, tetanus and many others.

Thus, the selected option is correct.

How many kJ to hear 0.700 pint of room temp water to boiling
irina1246 [14]
Use the equation Q = mCT.

Q is the amount of energy in joules.

m is the mass in grams.

C is the specific heat of water (4.184 J/g °C).

T is the change in temperature.

0.700 pints = 331.224 g of water

Q = (331.224 g)(4.184 J/g °C)(100° C - 30° C)

Q = 97,008.885 J

Divide by 1,000 to convert to kilojoules:

97.009 kJ
