Answer: 708.2 grams

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Given : 38 g of H_2SO_4 is dissolved in 100 g of solution.

Density of solution = 1.285 g/ml

Volume of solution = \frac{mass}{density}=\frac{100g}{1.285g/ml}=77.8ml

Thus if 77.8 ml of H_2SO_4 contains = 38 g of H_2SO_4

1.45L= 1450 ml of H_2SO_4 contains = \frac{38}{77.8}\times 1450=708.2 g of H_2SO_4

Therefore, the mass of the sulfuric acid in a car battery is 708.2 g

How much heat is transferred in the process of completely melting a 1.6kg block of ice starting at -15 degrees Celsius? Is this
mixas84 [53]

Answer:

  • a) Heat = 590 kJ

  • b) Endothermic

Explanation:

<em>Endothermi</em>c processes absorb energy. The final state contains more energy than the initial state.

Since ice absorbs heat energy <em>in the process of completely melting</em> this is an <em>endothermic</em> process.

The process involves two stages: 1) heating the ice up to the melting point, which is 0ºC, and 2) melting the ice.

1. Heating the ice from -15ºC to 0ºC

a) Formula: Q = m×C×ΔT

  • m = 1.6 kg
  • C = 2.108 kJ/kg.ºC (specific heat of ice)
  • ΔT = 15ºC

b) Calculations:

  • Q = m×C×ΔT = 1.6 kg × 2.108 kJ/kg.ºC  × 15ºC = 50.592 kJ

2. Melting the ice at 0ºC

a) Formula:  L = m × ΔHf

  • m = 1.6 kg
  • ΔHf = 334 kJ/kg (latent heat of fussion)

b) Calculations

  •    L = m × ΔHf = 1.6 kg × 334 kJ/kg = 534.40 kJ

<u />

<u>2. Total heat</u>

<u />

  • 50.592 kJ + 534.40 kJ = 584.992 kJ ≈ 590 kJ (rounded to 2 significant figures)

Which of the following describes a use of thermal energy? * A heater warming a room A flashlight shining on a wall A football fl
katrin2010 [14]

Answer:

A heater warming a room

Explanation:

The reason is that thermal energy is heat. The first option is the only one that has heat in it. A flashlight shining in a wall shows light energy. A football flying through the air shows potential energy to kinetic energy. A radio playing a song shows sound energy. The only answer that shows thermal energy is the first one.  I hope I was able to help! :)

Written in this form, carbon-13, what does the 13 represent and what is the atomic number?
tigry1 [53]
Explanation:
Carbon has 3 isotopes. Carbon-12, Carbon-13, and Carbon-14
All of them have an atomic number of 6, which means all of them have 6 protons (if they had different numbers of protons, they'd be different elements).
Since they all have 6 protons, in their elemental forms, they all have 6 electrons, too.
Carbon-12:
Atomic number: 6
Mass number: 12
protons: 6
electrons: 6
neutrons: 6
Carbon-13:
Atomic number: 6
Mass number: 13
protons: 6
electrons: 6
neutrons: 7
Carbon-14:
Atomic number: 6
Mass number: 14
protons: 6
electrons: 6
neutrons: 8
