Answer: 1255.2 kJ

Explanation:.

Energy is the capacity to do work. It is expressed in units like calories, Joules and ergs.

These units of energy are inter convertible.

We are given:

Energy present in soda = 300 cal

Converting this unit of energy into kilojoules

1 cal=4.184J

Thus 300cal=\frac{4.184}{1}\times 300=1255.2kJ

Thus, kilojoules present in soda is equal to 1255.2.

The ratio which denotes the relation between the two different units is said to conversion factors.

According to conversion factors, the relation between calorie and kilojoule is given as, one Calorie is equal to 4.184 kJ.

1 Cal = 4.184 kJ

Now, according to above relation, convert 300 calories into kilojoules.

300 calories =300 Cal\times \frac{4.184 kJ}{1 Cal}

= 1255.2 kJ

\simeq 1255 kJ

Thus, kilojoules present in soda is equal to 1255 kJ

Explain the bonding that occurs between sodium and chlorine. Specifically, what kind of bonding takes
babymother [125]

Answer:

Ionic bonds form when atoms transfer electrons between each other, forming ions that are electrically attracted to each other forming a bond between them. Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion.

Explanation:

ionic bond

Because of the propensity of sodium to lose an electron and of chlorine to gain an electron, the elements are well suited to bond with one another. This transfer of electrons results in the formation of the ionic bond holding Na+ and Cl– together.

I’m having hard time to understand can someone answer it and explain it
tekilochka [14]

Number #2 is joule

In the SI system the unit of heat is the joule. The calorie was defined so that the heat capacity of water was equal to one.The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree.

Number #3 is Endothermic

Why? I can't explain. I Just left class where they were just explaining that.

How long would it take for a car to travel 200km if it has an aventage speed of 55 km/ hr
krek1111 [17]

Answer:

It would take 3.64 hours to travel.

Explanation:

200km with 55 per hour.

200 divided by 55 would equal 3.64.

I am dividing because to solve time would be distance/rate.

I hope this helps! :)

Determine the approximate amount of potassium hydrogen phthalate, KHP, that you will need to neutralize 6.00 ml of 0.100 M NaOH.
Sveta_85 [38]

Answer:

potassium hydrogen phthalate KHP MOLAR MASS = 204.233 glmol

to get 1000 ml

Molar concentration = Mass concentration/Molar Mass

mass concentration = molar concentration x molar mass

mass concentration=0.1 M,

molar mass= 204.233 g/mol

so to get 1L

mass conc = 204.233 x 0.1

= 20.4233g  for 1L or 1000 ml

to get 6.00 ml

if 20.4233g is for 1000ml

then to 6.00 ml

= 20.4233 x 6 / 1000

= 0.123g for 6.00 ml

according to the equation below

NaOH(aq) + KHC8H4O4(aq) --> KNaC8H4O4(aq) + H2O(l)

number of moles of NaOH is equal to that of KHP

so the same amount will be needed too, which is

= 0.123g
