Answer:

A compound is a material formed by chemically bonding two or more chemical elements.

Explanation:

Answer:

Thus, to calculate the stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction. The mass ratios can be calculated by dividing each by the total in the whole reaction.

Explanation: Stoichiometry is the field of chemistry that is concerned with the relative quantities of reactants and products in chemical reactions. For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products.

Answer:

when you burn wood in a campfire, chemical energy is converted to heat and light energy.

Explanation :

When wood is burned stored potential energy ( in the form of chemical energy ) in the log is released due to heating by other excited atoms . This process is called combustion and requires presence of oxygen. So,  combustion can be defined as a process which changes chemical energy into kinetic energy in the form of heat.  In case of combustion  an organic say wood in this case combines with oxygen present in the atmosphere to give off carbon dioxide, water and energy in the form of heat and light .

Answer:

Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.

Explanation:

Answer:

Sample Response: Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.

If you want to make your own make sure to include.

- Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy.

- An unstable isotope will continue to decay until it reaches a stable form.

- The stable form could be a different isotope of the same element that is stable or a different element that is stable.

Answer:

Hydrosulfuric acid will act as limiting reactant.

Explanation:

Given data:

Mass of iron(III) chloride = 3243.0 g

Mass of hydrosulfuric acid = 511.8 g

Limiting reactant = ?

Solution:

Chemical equation:

2FeCl₃ + 3H₂S       →       Fe₂S₃ + 6HCl

Number of moles of iron(III) chloride:

Number of moles = mass/molar mass

Number of moles = 3243.0 g/ 162.2 g/mol

Number of moles = 20 mol

Number of moles of hydrosulfuric acid:

Number of moles = mass/molar mass

Number of moles = 511.8 g/ 34.1 g/mol

Number of moles = 15 mol

Now we will compare the moles of both reactant with products

                      FeCl₃          :          Fe₂S₃

                       2                :            1

                      20               :          1/2 ×20 = 10

                      FeCl₃          :            HCl

                       2                :              6

                      20               :          6/2 ×20 = 60

                      H₂S             :          Fe₂S₃

                       3                :            1

                      15               :          1/3 ×15 = 5

                      H₂S            :            HCl

                       3                :              6

                      15                :          6/3 ×15 = 30

Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.

The volume of the suspension required : 10 ml

Given

0.500 g of ampicillin

The liquid suspension concentration = 250 mg/5 mL

Required

The volume of the suspension required

Solution

The concentration of a substance can be expressed in various units such as molarity, ppm, g / L etc.

Each unit change, we must pay attention to the conversion factor

Conversion g to mg

0.5 g = 500 mg

The volume of the suspension needed :

=mass x concentration

[tex]\tt \dfrac{500~mg}{250~mg/5~ml}=500~mg\times \dfrac{5~ml}{250~mg}\\\\=10~ml[/tex]

Answer:

Explanation:

i am not sure that it's is right or wrong

Answer:

It has mass but no charge.

Explanation:

The question asks to describe ONE of the subatomic particles that could be found at location X in the model, so you should think of protons and neutrons. Now all of the answers do NOT describe a proton, but the first answer describes a neutron. Neutrons have mass but no charge. Why? The neutron has two down quarks and one up quark, down quarks, have a charge of -1/3, and up quarks have a charge of +2/3. Doing the math, you'd see that (-1/3)2+2/3 is equal to a neutral charge. So a neutron WILL have a mass, but will NOT have a charge, as they are used to hold the nucleus together.

The Mitochondria

Explanation:

Mitochondria are membrane-bound cell organelles that generate most of the energy required to power the cell's organic chemistry reactions. Energy created by the mitochondria is kept in a tiny molecule known as  adenosine triphosphate (ATP).

Answer:

9 g/ml

Explanation:

5 + 3.3 = 8.5

But you should use sig figs.

5 has no tenths, hundredths, and etc.

Therefore the 8.5 rounds up to 9

So the answer is 9.

Answer:

No! The balanced equation is given below:

C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O

Explanation:

C₆H₁₀O₅ + O₂ —> CO₂ + H₂O

The equation above is not balanced. It can be balance as illustrated below:

C₆H₁₀O₅ + O₂ —> CO₂ + H₂O

There are 6 atoms of C on the left side and 1 at the right side. It can be balance by 6 in front of CO₂ as illustrated below:

C₆H₁₀O₅ + O₂ —> 6CO₂ + H₂O

There are 10 atoms of H on the left side and 2 atoms on right side. It can be balance by 5 in front of H₂O as illustrated below:

C₆H₁₀O₅ + O₂ —> 6CO₂ + 5H₂O

There are a total of 7 atoms of O on the left side and a total of 17 atoms on the right side. It can be balance by 6 in front of O₂ as illustrated below:

C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O

Now, the equation is balanced.
