<h3><u>Answer;</u></h3>

Decomposition of calcium carbonate

CaCO3(s) → CaO(s) + CO2(g)

<h3><u>Explanation;</u></h3>
  • <em><u>Decomposition reactions are types of reaction that occurs when a reactant is broken down into two or more products. </u></em>
  • Decomposition may either be thermal where heat is used to break a reactant or may be catalytic where a catalyst is used to break down a reactant to yield two or more substance, for example decomposition of hydrogen peroxide.
  • <em><u>All metal carbonates decompose to produce a metal oxide and carbon dioxide gas.</u></em>
  • <em><u>Calcium carbonate undergoes thermal decomposition to form calcium oxide and carbon dioxide. </u></em>
  • The equation will be;

CaCO3(s) → CaO(s) + CO2(g)

The equation is balanced as the number of atoms of each element are equal on both side.

Yuki888 [10]
The correct answer for the question is Chordophone 
Chordophone is an instrument in which a stretched, vibrating string produces the initial sound. Strings instruments produce sound through the vibration of strings. The length, tightedness, and thickness determines the sound produced by the strings.

How high was a brick dropped from if if falls in 2.5 seconds?
jenyasd209 [6]
Using the kinematic equation d =  V_0 * t  + 1/2 * a * t^2, where d is height you can rewrite this to be d = 1/2*g*t^2 or 4.9t^2
g = a because this is a free fall 
d = 1/2 * 9.81m/s^2 * 2.5^2
d = 30.65625m
d = 30.7m

A stuffed toy with a mass of 0.900 kilograms sits on the edge of a bed at a height of 0.830 if the toy falls off the bed what wi
Olenka [21]
Mechanical energy (ME) is the sum of potential energy (PE) and kinetic energy (KE). When the toy falls, energy is converted from PE to KE, but by conservation of energy, ME (and therefore PE+KE) will remain the same.

Therefore, ME at 0.500 m is the same as ME at 0.830 m (the starting point). It's easier to calculate ME at the starting point because its just PE we need to worry about (but if we wanted to we could calculate the instantaneous PE and KE at 0.500 m too and add them to get the same answer).

At the start:

ME = PE = mgh
ME = 0.900 (9.8) (0.830)
ME = 7.32 J

What speed must an electron have if its momentum is to be the same as that of an x-ray photon with a wavelength of 0.30?
lorasvet [3.4K]

The momentum of the x-ray photon is p = h/lambda . Lambda is the wavelength (0.30nm=3x10^(-9)m) and h is Planck's constant,(h=6.62607004 × 10-34<span> m2 kg / s).The momentum is: 2.2 x 10^(-25).</span>

The momentum can be calculated also as: p=mv, where m is the mass of the electron and v is the speed.

So v=p/m,p is known,and also the mass of the electron (m=9.10938356 × 10-31<span> kilograms).</span>

v=2.2 x 10^(-25)/9.10938356 × 10-31<span> kilograms=0.24 x 10^6 m/s</span>
