The specific heat of the metal is 241.05 J/kg°C

<h3>What is specific heat capacity?</h3>

Specific heat capacity can be defined as the amount of heat required to raise a unit mass of metal through 1 °C

To calculate the specific heat capacity of the metal, we use the formula below.

Formula:

  • Q = cm(t'-t)............... Equation 1

Where:

  • Q = Heat absorbed by the metal
  • c = specific heat capacity of the metal
  • m = mass of the metal
  • Δt = increase in temperature

make c the subject of the equation

  • c = Q/m(Δt)................. Equation 2

From the question,

Given:

  • Q = 25.6 J
  • m = 90 g = 0.09 kg
  • Δt = 1.18 °C

Substitute these values into equation 2

  • c = 25.6/(1.18×0.09)
  • c = 241.05 J/kg°C

Hence, the specific heat capacity of the metal is 241.05 J/kg°C.

In an alkane the mass ratio between hydrogen and carbon is 7/36. What is the formula of alkane?
ch4aika [34]

Answer:

CnH2n+2 formula

Explanation:

Alkanes have the general formula CnH2n+2, so if an alkane had 7 carbon atoms, it would have the molecular formula C7H16.

Jarvis checked his odometer reading when filling his tank, and then checked it several days later when he filled his tank again.
8_murik_8 [283]

Answer: 26.25 miles per gallon

Explanation: first odometer reading = 65290

Second odometer reading = 65500

Difference in odometer reading = second reading - first reading

= 65500 - 65290 = 210 miles.

If it took 8 gallons to fill his tank, it means

8 gallons will get him 210 miles, therefore 1 gallon will get 210 miles/8gallons = 26.25miles/gallon. Hence he is getting 26.25miles/gallon.

Select True or False: The equilibrium constant for the chemical equation 2NO(g) O2(g) 2NO2(g) is two times the equilibrium const
ser-zykov [4K]

Answer:

False

Explanation:

The first reaction is;

NO(g) + 1/2O2(g) ---->NO2(g)

K= [NO2]/[NO] [ O2]^1/2

The second reaction is;

2NO(g) + O2(g) ---->2NO2(g)

K'= [NO2]^2/[NO]^2 [O2]

It now follows that;

K'= K^2

Hence the statement in the question is false

What do all atoms of the same element have
nordsb [41]

Answer:

All atoms of the same element have always have the same amount of protons.

Explanation:

Atoms of the same element have always have the same amount of protons but not always the same electrons and neutrons. If an atom gains or loses one of its valance electrons, the electrons on the outermost shell, then it becomes ionized. Also not all atoms of the same element have the same amount of neutron. This is called an isotope. A good example would be Carbon 13. Normally, Carbon atoms have an atomic mass of 12 AMU or 12 atomic mass units. However, Carbon atoms have an atomic mass of 13 AMU, consisting of 7 neutrons instead of 6 neutrons. So the only thing that all atoms of the same element have in common is the amount of protons.
