The ionic compound that results from the reaction between an acid and a base is called salt

Ions are present in ionic compounds, which are held together by the attraction interactions between the ions with opposing charges. One of the most well-known ionic compounds is table salt or sodium chloride. Molecular compounds are made up of separate molecules that are connected by sharing electrons (covalent bonding).

The simplest way to determine whether a chemical compound is an ionic compound is to see if it only contains two elements, one of which can be a metal (belonging to either of groups 1, 2, or 3), and the other of which can be a non-metal (from group 5, 6 or 7). An illustration of an ionic compound is table salt. The compound sodium chloride, or NaCl, is created when sodium and chlorine ions combine.

If the mass of a block of wood is 4.6g and the density is 0.98g/mL what is the volume.

irina [24]

Answer:

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass of wood = 4.6 g

density = 0.98 g/mL

It's volume is

$volume = \frac{4.6}{0.98} \\ = 4.69387755...$

We have the final answer as

Calculate the mass of 29.6 L of fluorine gas at STP.

Lunna [17]

Answer:

Mass = 25.08 g

Explanation:

Given data:

Volume of fluorine = 29.6 L

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Mass of fluorine = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

n = PV/RT

n = 1 atm × 29.6 L / 0.0821 atm.L/ mol.K × 273.15 K

n = 1.32 mol

Mass of fluorine:

Mass = number of moles × molar mass

Mass = 1.32 mol ×19 g/mol

Mass = 25.08 g

CaC2(s) + 2H2O(l) --> Ca(OH)2(aq) + C2H2(g) In the reaction above, 0.5487 grams of calcium carbide are completely consumed to

jasenka [17]

Answer:

239.7mL

Explanation:

Using the general gas equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas constant (0.0821 Latm/molK)

T = temperature (K)

The balanced chemical equation in this question is as follows:

CaC2(s) + 2H2O(l) --> Ca(OH)2(aq) + C2H2(g)

From the equation, 1 mole of CaC2 produces 1 mole of ethylene gas, C2H2.

Using mole = mass/molar mass

Molar mass of CaC2 = 40 + 12(2)

= 40 + 24

= 64g/mol

mole = 0.5487/64

mole = 0.00857mol of CaC2

Hence, 0.00857mol of CaC2 produced 0.00857mol of C2H2

Based on the information provided, n = 0.00857mol, T = 43°C = 43 + 273 = 316K, p = 0.926 atm

PV = nRT

V = nRT/P

V = 0.00857 × 0.0821 × 316/0.926

V = 0.222/0.926

V = 0.2397L

In mL, volume = 0.2397 × 1000

= 239.7mL
