Answer:

The sugar atoms formed new atoms after caramelization.

Explanation:

When sugar is heated to a certain temperature, it becomes caramel. Te formation of caramel from the sugar is a chemical process.

In the context, Pedro is doing an investigation by heating sugar to make caramel. Burning of the sugar crystal is a chemical change as different chemicals are present in both. The caramel formed cannot be revered back to sugar crystal, this also proves the chemical change of caramelization of sugar cubes. Sugar consists of carbon, oxygen and hydrogen atoms. It reacts with atmospheric oxygen atoms to form new groups of atoms and forms caramel.

Vikki [24]
I think the substance that will heat up faster would be the silver metal since it has a higher heat capacity. Heat capacity is the amount of heat needed to raise the temperature of the system into one degree. Heat capacity and heat energy is directly related so higher value of heat capacity would lead to higher heat energy.

A sample of calcium oxide (CaO) has a mass of 2.80 g. The molar mass of CaO is 56.08 g/mol. How many moles of CaO does this samp
Molodets [167]

Answer is "0.05 mol".

<em>Explanation;</em>

We can do calculation by using a simple formula as

n = m/M

Where, n is the number of moles of the substance (mol), m is the mass of the substance (g) and M is the molar mass of the substance (g/mol).

Here,

n = ?

m = 2.80 g

M = 56.08 g/mol

By substitution,

n = 2.80 g /56.08 g/mol

n = 0.0499 mol ≈ 0.05 mol

Why is the greenhouse effect important to life on earth
navik [9.2K]

Answer:

Because Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. And this way, they act like the glass walls of a greenhouse. This greenhouse effect also keeps the Earth warm enough to sustain life.
