<span>A chemical reaction in which compounds break up into simpler constituents is D. decomposition. This should be an obvious answer - when something decomposes, it falls apart and creates smaller parts of the original thing. The same thing goes with the compounds - they will fall apart into constituents that are way simpler than them. </span>

A 70.0-g piece of copper metal at 54.0 °C is placed in 50.0 g of water at 26.0 °C. If the final temperature of the water and met

KatRina [158]

The specific heat in, J /g °C of copper is 0.386J/g°C

HOW TO CALCULATE SPECIFIC HEAT CAPACITY OF A SUBSTANCE:

The specific capacity of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

Q = quantity of heat absorbed or released (J)

m = mass of substance (g)

∆T = change in temperature (°C)

c = specific heat capacity (J/g°C)

For a colorimeter, the following equation applies:

m.c.∆T (water) = - m.c.∆T (metal)

For water:

m = 50g

c = 4.184 J/g°C

∆T = 29.2 - 26°C = 3.2°C

For copper:

m = 70g

c = ?

∆T = 29.2 - 54°C = -24.8°C

m.c.∆T (water) = - m.c.∆T (metal)

50 × 4.184 × 3.2 = -(70 × c × -24.8)

669.44 = 1736c

c = 669.44 ÷ 1736

c = 0.386J/g°C

Therefore, the specific heat in, J /g °C of copper is 0.386J/g°C

What is the frequency of a wave traveling west with a velocity of 414 meters per second and a wavelength of 1.8 meters? hertz

LuckyWell [14K]

Answer:

230hz

Explanation:

Hello,

To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.

V = Fλ

V = velocity or speed of the wave

F = frequency of the wave

λ = wavelength of the wave

Data;

V = 414m/s

λ = 1.8m

f = ?

V = fλ

f = v/λ

f = 414/1.8

f = 230hz

The frequency of the wave is 230hz

What is the [h3o ] for a solution of seawater at 25°c that has a ph of 8.3?

Kipish [7]

PH of solution at 25ºC = 8.3

$[ H_3O^+] = 10 ^{-pH}$

${H_3O^+] = 10 ^{-8.3}$

$[H_3O^+] = 5.011*10^{-9} M$

hope this helps!
