Answer:

150g-125g

=25 of hot chocolate mix

Answer:

[tex]0.75\ \text{M}[/tex]

Explanation:

[tex]C_1[/tex] = Concentration of [tex]Na_2CO_3[/tex]

[tex]C_2[/tex] = Concentration of [tex]HCl[/tex] = 1 M

[tex]V_1[/tex] = Volume of [tex]Na_2CO_3[/tex] = 20 mL

[tex]V_2[/tex] = Volume of [tex]HCl[/tex] = 15 mL

We have the relation

[tex]V_1C_1=V_2C_2\\\Rightarrow C_1=\dfrac{V_2C_2}{V_1}\\\Rightarrow C_1=\dfrac{15\times 1}{20}\\\Rightarrow C_1=0.75\ \text{M}[/tex]

The concentration of [tex]Na_2CO_3[/tex] is [tex]0.75\ \text{M}[/tex].

Answer:

Calcium iron oxide (CaFe2O4)

Molecular Formula CaFe2H8O4

Synonyms Calcium iron oxide (CaFe2O4) 12013-33-1 Calcium ferrite EINECS 234-584-5

Molecular Weight 223.83 g/mol

Component Compounds CID 23925 (Fe) CID 5460341 (Calcium) CID 962 (Water)

Answer:

Melting points are often used to characterize organic and inorganic crystalline compounds and to ascertain their purity. Pure substances melt at a sharp, highly-defined temperature (very small temperature range of 0.5 – 1 °C) whereas impure, contaminated substances generally exhibit a large melting interval.

Answer: [tex]8.38\times 10^{23}atoms[/tex] of carbon

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

mass of sugar= [tex]density\times volume=1.59g/ml\times 25ml=39.75g[/tex]

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{39.75g}{342.3g/mol}=0.116moles[/tex]

1 mole of sugar [tex]C_{12}H_{22}O_{11})[/tex] contains = [tex]12\times 6.023\times 10^{23}=72.28\times 10^{23}atoms[/tex] of carbon

0.116 mole of sugar [tex]C_{12}H_{22}O_{11})[/tex] contains = [tex]\frac{72.28\times 10^{23}}{1}\times 0.116=8.38\times 10^{23}atoms[/tex] of carbon

Answer:

binary and 11

Explanation:

CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent bonding. In case of calcium chloride, the calcium gives up an electron to each chlorine atom, becoming Ca2+ ions and chlorine become Cl– ions.

Answer:

Number of Fe atoms = 2.709 × 10^23 atoms.

Explanation:

Given the following data;

Number of Fe moles = 0.450 mole

We know that Avogadro constant is equal to 6.02 * 10^23 mol¯¹

Number of Fe atoms = number of Fe moles * Avogadro constant

Substituting into the equation, we have;

Number of Fe atoms = 0.450 × 6.02 * 10^23

Number of Fe atoms = 2.71 × 10^23 atoms.

Note: Fe is the symbol for the chemical element Iron.

1. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

2. Given below are some of the examples of the chemical reactions in our daily life:

Photosynthesis.

Combustion.

Aerobic cellular respiration.

Anaerobic respiration including the process fermentation.

Metathesis reactions, for example, vinegar and baking soda.

Oxidation which includes rusting.

Digestion.

3. A chemical formula is the combination of atomic symbols that designate a particular chemical compound, or a substance with two or more different elements. ... A chemical equation shows one or more chemical compounds (reactants) being converted into different chemical species called products.

Answer:

Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.

Answer:

it produce atp

Explanation:

.............

Cellular respiration is a metabolic process that occurs in the cells of an organism. Carbon dioxide from cellular respiration aids the process of photosynthesis.

Cellular respiration is a process that takes place in the organism's cell where the cellular oxygen or chemical energy gets utilized and converted to ATP and waste like carbon dioxide.

The carbon dioxide released by the organism in the atmosphere is used by plants in the process of photosynthesis. Photosynthesis is a process that utilizes carbon and water to form glucose and oxygen.

Therefore, cellular respiration supports the process of photosynthesis by option D. producing carbon dioxide.

Answer:

Because the particles are in motion, they will have kinetic energy. The particles will not all have the same energy, and the energy of the particles is constantly changing as they undergo changes in speed. Thus, for a given sample of matter, we can only talk about the average kinetic energy of the particles.

Explanation:

I hope this helps and pls mark me brainliest :)

We do know that if we "give" energy to a given object, the temperature of the object increases.

So there is a direct relationship between temperature and energy.

From this idea, we can conclude that:

"As we increase the energy, we also will see an increase in molecular motion."

We also do know that, as the temperature of an object increases, also does the kinetic energy of the particles that conform to the object (as the kinetic energy increases, the particles move more, this is why as we increase the temperature we usually see an increase in the volume of the object).

This increase in kinetic energy is related to the molecular motion (the movement of the electrons and nucleus o a molecule) as the kinetic energy of these parts increase, these move more.

So the relationship between molecular motion and energy is:

As we increase the energy, we also will see an increase in molecular motion.

Answer:

Explanation:

mixture of iron filings, sand, and sugar

First Step - Iron Fillings

Use a magnet to separate the iron fillings from the mixture. Due to magnetic properties of the iron fillings, the magnets would attract the iron fillings and separate it from the mixture.

Second step - Sand

Place the sand and sugar mixture in water. The sugar would dissolve in water and the sand easily separated by filtration.

Third step - Sugar and Sugar water

Boil the sugar water to remove the water and place in the refrigerator for crystallization of the sugar.
