Describe particle movement in solid,liquid and gas

Chemistry
2 answers:
Law Incorporation [45]2 years ago
5 0

Answer:

In a solid, they're really close together and vibrate a LITTLE, in a liquid they're kinda close together but change movement because water will change shape depending on the container they're in. For gas they are spread far from each other and vibrate A LOT

A saturated solution of baso4 has a concentration of 0.5mol/l. a 55ml sample is taken by you. what is the mass of baso4 in the s
SIZIF [17.4K]

Answer:

6.4 g BaSO₄

Explanation:

You have been given the molarity and the volume of the solution. To find the mass of the solution, you need to (1) find the moles BaSO₄ (via the molarity ratio) and then (2) convert moles BaSO₄ to grams BaSO₄ (via the molar mass). It is important to arrange the conversions in a way that allows for the cancellation of units (the desired unit should be in the numerator). The final answer should have 2 sig figs to reflect the sig figs of the given values.

Molarity (mol/L) = moles / volume (L)

(Step 1)

55 mL / 1,000 = 0.055 L

Molarity = moles / volume                             <----- Molarity ratio

0.5 (mol/L) = moles / 0.055 L                        <----- Insert values

0.0275 = moles                                             <----- Multiply both sides by 0.055

(Step 2)

Molar Mass (BaSO₄): 137.33 g/mol + 32.065 g/mol + 4(15.998 g/mol)

Molar Mass (BaSO₄): 233.387 g/mol

0.0275 moles BaSO₄          233.387 g
---------------------------------  x  -------------------  =  6.4 g BaSO₄
                                                1 mole

which statement best describes the equation caco3 2hcl → cacl2 co2 h2o? caco3 is a reactant; it is present before the reaction o
fomenos

Answer: CaCO_3 is a reactant; it is present before the reaction occurs.

Explanation:

In a chemical reaction the chemical formulas written before the arrow are described as reactants as they react together to form products which are written after the arrow.

CaCO_3 + 2HCl \rightarrow CaCl_2 + CO_2 + H_2O

Thus CaCO_3 and HCl are reactants here whereas CO_2, CaCl_2 and H_2O are products.

How many grams of Carbon are in sample of 400 grams of Co2?​
RoseWind [281]

Answer:

Mass of carbon = 109.1 g

Explanation:

Given data:

Mass of carbondioxide = 400 g

Mass of carbon = ?

Solution:

Molar mass of carbon = 12 g/mol

Molar mass of CO₂ = 44 g/mol

Mass of carbon in 400g of  CO₂:

Mass of carbon = 12 g/mol/44 g/mol × 400 g

Mass of carbon = 109.1 g
