8 0

Answer:

The answer to your question is: letter A

Explanation:

A combination reaction is when there are two reactants that gives only one product.

a. 2SO2 + O2—> 2SO3                          This is a combination reaction,

                                                               2 reactants gives one product.

b. Zn + Cu(NO3)2–>Zn(NO3)2 + Cu     This is not a combination reaction,

                                                                it's a single replacement reaction.

c. 2H2O2–> 2H2O+O2                          This is a decomposition reaction

d. AgNO3 + NaCl → AgCl+NaNO3        THis is a double replacement reaction.

Sort the phrases about the mesosphere and the thermosphere into the correct categories.
kiruha [24]

Explanation:

Before proceeding, let's understand what thermosphere and mesosphere are;

The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere.

The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere.

The meteors make it through the exosphere and thermosphere without much trouble because those layers don't have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.

Temperatures in the mesosphere decrease with altitude. Because there are few gas molecules in the mesosphere to absorb the Sun's radiation, the

heat source is the stratosphere below. The mesosphere is extremely cold.

Satellites and the International Space Station orbit the Earth within the thermosphere.

Mesosphere;

- is directly above the stratosphere

- acts as a barrier to meteoroids

- is very cold

Thermosphere;

- reaches out into space

- is where satellites travel

The heat absorbed to raise temperature : Q = 31350 J

<h3>Further explanation </h3>

Given

m = mass = 150 g

Δt = Temperature difference : 50 °C

Required

Heat absorbed

Solution

Heat can be formulated

<em> Q = m.c.Δt </em>

The specific heat of water = c = 4.18 J/g °C  

Input the value :

Q = 150 x 4.18 x 50

Q = 31350 J
