Answer:

It is not possible to determine the type of chemical reaction that will occur when Ca LiOH → without additional information. The chemical formula Ca LiOH could represent a compound, but without knowing what reactants are present and what products are being formed, it is not possible to classify the reaction. Some possible reactions that could occur involving Ca LiOH include a synthesis reaction, where Ca LiOH is formed from its constituent elements, a decomposition reaction, where Ca LiOH breaks down into its constituent elements, or a substitution reaction, where one or more atoms in Ca LiOH are replaced by other atoms.

How many molecules are found in 3.4 moles of carbon dioxide?

madam [21]

Answer:

One mole of anything has 6.023 x 10^23 molecules.

That would mean 3.4moles of CO2 have 6.023x 10^23 times 3.0.

So that would be2.04782×10^24 molecules in 3.0 moles of C02.

Using the accompanying chart, calculate the volume of a Densities of Group 14 Elements tin block that has a mass of 95.04 grams

saw5 [17]

<u>Answer:</u> The volume of given mas of tin block at STP is $13.0cm^3$

<u>Explanation:</u>

To calculate volume of of the substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Mass of tin = 95.04 g

Density of tin = $7.31g/cm^3$

Putting values in above equation, we get:

$7.31g/cm^3=\frac{95.04g}{\text{Volume of tin}}\\\\\text{Volume of tin}=\frac{95.04g}{7.31g/cm^3}=13.0cm^3$

Hence, the volume of given mas of tin block at STP is $13.0cm^3$

To test Döbereiner’s idea, predict:

Rudik [331]

Answer:

a) Approximate boiling point of HBr = -60.15 °C

b) Approximate boiling point of AsH₃ = -52.25 °C

Explanation:

Döbereiner stated that some elements could be arranged in groups of 3 similar elements ( known as "triads) , and the element of the middle ( elements are ordered with respect to their atomic mass) would have properties between the other 2 ( the average value)

a) In the first case the triad would be the halogen triad ( Cl , Br and I ) . And according to Döbereiner , the boiling point of HBr should be the average of HCl and HI . Therefore

Approximate boiling point of HBr = [(- 84.9°C) + (-35.4°C)]/2 = -60.15 °C

b) Simmilarly for AsH₃ , PH₃ and SbH₃ , the boiling point of AsH₃ would be

Approximate boiling point of AsH₃ = [(- 87.4°C) + (-17.1°C)]/2 = -52.25 °C

Which statement gives the main idea of the kinetic theory of heat?

seraphim [82]

Answer:

The best option is "Heat is transferred by the interaction of moving particles."

Explanation:

The Kinetic Molecular Theory of Heat states that molecules in a fluid increase their speed as temperature increases.

Kinetic theory of heat is a theory that the temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.

Heat and temperature are related to each other, but are different concepts.

1. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance.

2. Temperature does not depend on the size or type of object.

Also heat can be transferred but temperature can't be transferred.
