How much heat energy is needed to raise the temperature of 59.7g of cadmium from 25°C to 100°C? The specific heat of cadmium is 0.231 J/g °C.

Answers

Answer 1
Answer: Heat energy can be calculated by using the specific heat of a substance multiplying it to the mass of the sample and the change in temperature. It is expressed as: 

Energy = mCΔT
Energy = 59.7 (0.231) (100-25)
Energy = 1034.30 J
Answer 2
Answer:

The amount of heat energy needed to raise the temperature of 59.7g of cadmium from 25°C to 100°C is 1,034.3J.

How to calculate amount of energy?

The amount of heat energy needed to raise a temperature can be calculated using the following expression;

Q = mc∆T

Where;

  • Q = amount of energy released or absorbed
  • m = mass of substance
  • c = specific heat capacity
  • ∆T = change in temperature

According to this question, 59.7g of cadmium is needed to be raised from 25°C to 100°C. The amount of heat needed can be calculated as follows:

Q = 59.7 × 0.231 × (100 - 25)

Q = 1,034.3J

10 Which statement correctly describes the location and charge of the electrons in an atom?F The electrons are inside the nucleus and have no charge.
G The electrons are outside the nucleus and have no charge.
H The electrons are inside the nucleus and have a negative charge.
The electrons are outside the nucleus and have a negative charge.


which is correct

Answers

Answer:

D. The electrons are outside the nucleus and have a negative charge.

Explanation:

Electrons are located outside the nucleus while protons and neutrons are located inside the nucleus.

Electrons are negatively charged and attracted to nucleus as the nucleus carry protons that are positively charged and neutrons have no charge.

Electrons are arranged in different energy levels based on the attraction between the positively charged nucleus and negatively charged electron.

Hence, the correct answer is "D. The electrons are outside the nucleus and have a negative charge."

The molar mass CO2 is 44.01 g/mol. How many moles of LiOH are needed to react completely with 25.5 g of CO2?

Answers

I'm using an equation with CO₂ and LiOH in it as an example. Use this setup and replace with the values in your equation.

LiOH + CO₂ = LiCO₃ + H₂O

25.5g CO₂ x1 mole CO₂ x 1 mole LiOH = 0.58 mole LiOH
                     44.01g CO₂    1 mole CO₂
                                             ^ you get these coefficients from the equation
