Answer:

Kinetic energy

Explanation:

The kinetic energy of a particle is directly proportional to the temperature of it. An increase in temperature increases the speed in which the molecules move, causing t[he particles to collide with the walls of their containers.

How many moles of carbon in 6.64 moles of CCl2 F

Bad White [126]

Answer: 6.64 moles of carbon.

Explanation:

Given data:

Number of moles of C = ?

Number of moles of CCl₂F₂ = 6.64 mol

Solution:

In one mole of CCl₂F₂ there is one mole of carbon two moles of chlorine and two moles of fluorine are present.

In 6.6 moles of CCl₂F₂ :

Moles of carbon = 6.64 × 1 = 6.64 moles of carbon.

Moles of chlorine = 6.64× 2 = 13.28 moles of chlorine

Moles of fluorine = 6.64× 2 = 13.28 moles of fluorine

Sodium carbonate reacts with silver nitrate according to the following balanced equation: Na2CO3 (s) + 2 AgNO3 (aq) → Ag2CO3 (s)

klemol [59]

Answer:

a) 2.01 g

Explanation:

Na₂CO₃ (s) + 2AgNO₃ (aq) → Ag₂CO₃ (s) + 2NaNO₃

First we convert 0.0302 mol AgNO₃ to Na₂CO₃ moles, in order to calculate how many Na₂CO₃ moles reacted:

0.0302 mol AgNO₃ * $\frac{1molNa_2CO_3}{2molAgNO_3}$ = 0.0151 mol Na₂CO₃

So the remaining Na₂CO₃ moles are:

0.0340 - 0.0151 = 0.0189 moles Na₂CO₃

Finally we convert Na₂CO₃ moles into grams, using its molar mass:

0.0189 moles Na₂CO₃ * 106 g/mol = 2.003 g Na₂CO₃

The closest answer is option a).

1. Hermione is trying to replicate the Polyjuice Potion that they created in their second year at Hogwarts. The problem is that

faltersainse [42]

Answer:

A) Test(independent) variable is bat wings.

B) Result (dependent) Variable is the Polyjuice Potion.

C) Cauldrons and fire

Explanation:

A) A test/independent variable is the variable that is being tested in the experiment or research and it is not affected by other variables in the experiment.

Now, in this experiment, what is being tested is are the bat wings.. Thus;

Test(independent) variable is bat wings.

B) Result (dependent) Variable is a variable that depends on the independent variable being tested. From the question, the result is the Polyjuice Potion.

Thus, Result (dependent) Variable is the Polyjuice Potion.

C) The constants are things that don't change with respect to any of the other variables. In this case, they are; cauldrons and fire
