NaCl = Sodium(Na) Chlorine(Cl)

Answer = Chlorine,Sodium (Alphabetically)

Explanation:

Sodium chloride, also identified as salt, is an ionic compound with the chemical formula NaCl, drawing a 1:1 ratio of sodium and chloride ions. Sodium chloride also has numerous different uses for seasoning and storing foods. Hospitals use an intravenous sodium chloride solution. Sodium Chloride Injection 0.9% can also be practiced as a dry irrigation solution.

What is the total mass of KNO3 that must be dissolved in 50. grams of H2O at 60.°C to make a saturated solution?
IRINA_888 [86]

at 60ºC:

106 g KNO₃ -------------- 100 g (H₂O)
? g KNO₃ ------------------ 50.0 g (H₂O)

mass KNO₃ = 50.0 * 106 / 100

mass KNO₃ = 5300 / 100

<span>= </span>53 g of KNO₃

Atomic number and atomic mass
Alexeev081 [22]

Answer:

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

What is the specific heat capacity of silver metal if 55.00 g of the metal absorbs 193.9J of heat and the temperature rises 15.0
skad [1K]

Answer:

The specific heat capacity of silver is 0.24 j/g.°C.

Explanation:

Given data:

Mass of sample = 55.00 g

increase of temperature ΔT= 15.0 °C

Heat absorbed = 193.9 J

Specific heat capacity of silver = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance.

ΔT = change in temperature

Now we will put the values in formula.

193.9 J = 55.00 g × c ×15.0 °C

193.9 J = 825 g.°C  × c

c = 193.9 J / 825  g.°C

c= 0.24 /g.°C

The specific heat capacity of silver is 0.24 j/g.°C.
