How to write equations and show units for the Total joules gained by water for the Pringle and the Total Joules per gram of food
Paraphin [41]

Answers:

1. 7500 J; 3800 J/g

Step-by-step explanation:

1. Joules gained by water

q = mcΔT

Data:

m = 100 g

C = 4.184 J·°C⁻¹g⁻¹

ΔT = 18 °C

Calculation:

q = 100 × 4.184 × 18 =7500 J

2. Joules per gram of Pringle

Energy gained by water = energy lost by Pringle

q = -mΔH

7500 J = -1.984 g × ΔH

ΔH = -7500 J/1.984 g = -3800 J/g

Pringles contain 3800 J of food energy per gram.

If you heat a liquid and measure the temperature at which it boils, you are measuring a(n)
nika2105 [10]

Explanation:

The temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure is known as boiling point.

At the boiling point the liquid and vapor state of a substance remains in equilibrium till the time all molecules of liquid do not turn into vapor.

When all the liquid molecules change into vapor state then only there will occur a rise in temperature.

Properties that do not depend on the amount of matter are known as intensive properties.

For example, boiling point, melting point, density etc.

On the other hand, properties which depend on the amount of matter are called extensive properties.

For example, volume, density etc.

Thus, we can conclude that if you heat a liquid and measure the temperature at which it boils, you are measuring an intensive property.

Chlorine has two naturally occurring isotopes, ³⁵Cl and ³⁷Cl. What is the mass number of each isotope? How many protons, neutron
Arte-miy333 [17]

The mass number of ³⁵Cl and ³⁷Cl is 35 and respectively.

<h3>What is atomic mass? </h3>

Atomic mass is defined as the sum of number of protons and number of neutrons of an element.

Atomic mass is represented by A.

<h3>What is Atomic number?</h3>

Atomic number is defined as the number of electron in an element.

Atomic number is represented by Z.

<h3>What is Isotopes? </h3>

Isotopes are the element which have same atomic number but have different atomic mass.

Number of proton is equal to number of electrons.

Proton is positively charged, electrons are negativity charge while neutrons are neutral in nature.

Proton and neutrons are present in the nucleus of an element. On the other hand, electron revolves around the nucleus.

The atomic number of ³⁵Cl and ³⁷Cl is 17.

Number of protons = Number of electrons = 18.

Neutrons = atomic mass - atomic number

Neutrons of ³⁵Cl = 35-17 = 18

Neutrons of ³⁷Cl= 37- 17= 20

So, they have different atomic mass and number of neutrons.

Thus, we concluded that the mass number of ³⁵Cl and ³⁷Cl is 35 and 37 respectively.

Sav [38]

<em>Answer:</em>

  •                   0.052301 km have 5 significant figure
  •                   400 cm have 1 significant figure
  •                   50.0 m  have 3 significant figure
  •                  4500.01 ml have 6 significant figure

<em>Explanation:</em>

According to rules of significant figure

0.052301 km have 5 significant figure:

  • Zero to the left of the first non zero digit not significant.
  • Zero between the non zero digits are significant.

<em>400 cm have 1 significant figure:</em>

  • Trailing zeros are not significant in numbers without decimal points.

<em>50.0 m  have 3 significant figure:</em>

  • Trailing zeros are significant in numbers when there is decimal points.

<em>4500.01 ml have 6 significant figure:</em>

  • Zero between the non zero digits are significant.
