Ksivusya [100]

Ah , a cup of hot chocolate is alot of chocolate. Im gonna drool ; )

Well , heat flows from an area of high temperature to an area of low temperature. Here , hot chocolate has the high temp , and the surrounding has a room temp. So , the heat from the hot chocolate will dissipate into the surroundings and create a thermal equilibrium. So youre right.

C3H8 + 5 O2 → 3 CO2 + 4 H2O
Reika [66]

Answer:

Mass = 112 g

Explanation:

Given data:

Mass of CO₂ produced = 90.6 g

Mass of oxygen needed = ?

Solution:

Chemical equation:

C₃H₈ + 5O₂       →      3CO₂+ 4H₂O

Number of moles of CO₂:

Number of moles = 90.6 g/ 44 g/mol

Number of moles = 2.1 mol

Now we will compare the moles of  CO₂ and oxygen:

                 CO₂           :           O₂

                    3             :            5

                    2.1           :        5/3×2.1 = 3.5

Mass of oxygen needed:

Mass = number of moles × molar mass

Mass = 3.5 mol × 32 g/mol

Mass = 112 g

Fofino [41]

Option A is correct. When a person says "<em>I think</em><em> that between an elephant and a monkey that jumped off the cliff, both of them will hit the ground at the same time."</em> the person is stating his Hypothesis

A hypothesis is an explanation proposed or given based on a piece of evidence that is limited.

It is useful at the beginning of an investigation because it serves as the building block for an impending fact or law.

From the statement, we can see that the person is not too sure of the information provided since he "thinks". <em>He said, </em><em>"I think</em><em> that between an elephant and a monkey that jumped off the cliff, both of them will hit the ground at the same time." </em>

<em />

Hence we can conclude that the person is stating a hypothesis.

Law and theory are incorrect because they are already proven facts.
