Answer:

9.80 x 10⁻⁴

Explanation:

The negative means that the decimal place was moved to the right and the exponent tells you how many places it was moved.

What is the identity of a 100. g sample of metal that, upon absorbing 4680 J of heat, increases in temperature by 52.0°C?
krok68 [10]

The metal is aluminium

<u>Explanation:</u>

Given:

Heat, q = 4680 J

Mass, m = 100g = 0.1kg

ΔT = 52°C

sample = ?

We know:

q = mcΔT

On substituting the value we get:

4680 = 0.1 X c X(52)\\\\c = \frac{4680}{5.2} \\\\c = 900 J/Kg^oC

Thus, the metal is aluminium which has a specific heat capacity of 900 J/kg°C

What can you calculate with the Henderson-Hasselbalch equation
Mamont248 [21]

Answer:

Actually, The Henderson - Hasselbalch equation allows you to calculate the pH of the buffer by using the pKa of the weak acid and the ratio that exists between the concentrations of the weak cid and conjugate base.  The pKa of formic acid is equal to 3.75.  In this case, the pH of the solution will be equal to the acid's pKa .

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder
Elina [12.6K]

Answer:

The answers to the questions are as follows

  1. The temperature of the water bath goes up
  2. The piston moves out
  3. Heat flows out of the gaseous mixture
  4. 173.kJ flows out of the system

Explanation:

  • From the question, it is noted that 173.kJ of heat flows out of the system into the insulated water bath therefore the temperature of the water bath goes up

as seen in the relation ΔH = m·c·ΔT

Where ΔH heat measured by temperature  rise ΔT of a given mass of water m of specific heat capacity of 4.2 J/g°C

  • The amount of heat measured from previous experiment is more than the heat from the present reaction therefore since in the present reaction is constant pressure and from the first law of thermodynamics Energy can neither be created nor destroyed, the balance heat will be transformed to work evidence in the piston moving out

ΣH = Q + W  where

w = P × ΔV = P × (P₂ - P₂)

  • Heat flows out of the gaseous mixture and is sensed from the rise in the temperature of the water bath
  • 173.kJ flows out of the system

Which two phrases describe the movement of thermal energy due to
Varvara68 [4.7K]

Answer:

D. From the equator to cooler parts of Earth

Explanation:

Thermal energy is always transferred from an area with a higher temperature to an area with a lower temperature. Moving particles transfer thermal energy through a fluid by forming convection currents.
