You've just solved a problem and the answer is the mass of an electron, me=9.11×10−31kilograms. How would you enter this number into the answer box?

Answers

The mass of an electron can be expressed in the box as $\boxed{{m_e} = 9.1 * {{10}^( - 31)}{\text{ kg}}}$ .

Further explanation:

Atom is the smallest particle that can be present in any element. It is also known as the building unit of matter. Each atom has a central part that is known as the atomic nucleus. There are three subatomic particles that constitute the atom. These particles are protons, neutrons, and electrons. The atomic nucleus consists of protons and neutrons, both are collectively called nucleons. Electrons revolve around the nucleus of an atom in definite orbits.

Protons are positively charged subatomic particles, electrons are negatively charged and neutrons have no charge. Since electrons carry a unit negative charge, these create an electric field around them. These also participate in nuclear reactions. The mass of an electron $\left( {{m_e}} \right)$ is $9.1 * {10^( - 31)}{\text{ kg}}$ , that of protons is $1.6726219 * {10^( - 27)}{\text{ kg}}$ and that of neutrons is $1.674927471 * {10^( - 27)}{\text{ kg}}$ . The electrons are responsible for chemical properties of elements. The distribution and arrangement of electrons is used to predict whether the element will be inert or reactive.

Therefore the required answer is $\boxed{{m_e} = 9.1 * {{10}^( - 31)}{\text{ kg}}}$ .

C6H14 has a boiling point than C11H24.

Answers

The correct statement to complete the thought of the sentence is "lower boiling point". C6H14 or hexane has a lower boiling point than C11H24 since hexane has lower number of atoms than the latter. Lower number of atoms means less bond which results to lower bonds to break.

C6H14 has a lower boiling point than C11H24.

how many moles of oxygen gas (o2) are required to react with 3.75 moles of ammonia (nh3) in the reaction 4nh3 + 5o2 → 4no + 6h2o?

Answers

4 NH₃ + 5 O2 = 4NO + 6 H₂O

4 moles NH₃ ---------> 5 moles O₂
3.75 mols NH₃ -------> ?

Moles O₂ = 3.75 x 5 / 4

Moles O₂ = 18.75 / 4

= 4.6875 moles of O₂

Which of the following is a unit of density? = Mass / volumeA: liters per cubic gram
B:cubic meters
C:grams per cubic centimeter
D:square meters

Answers

Answer:

The correct answer is C.

Explanation:

To solve this problem, we should first recall possible units for mass and volume. Mass can be represented with units of grams, kilograms, etc. Volume has units of cubic meters, cubic centimeters, etc.

Therefore, since we know that density is mass divided by volume, the only answer that makes sense here is C. grams per cubic centimeter (where per signifies that grams are being divided by cubic centimeters).

Hope this helps!

I’m pretty sure it’s c- grams per cubic.

Explain how the system of the flask and the balloon illustrates the conservation of mass.

Answers

The mass of the reaction system is conserved because, the mass lost from the reaction by the evolution of gas is collected inside a balloon to inflate it. Thus , the balloon and the flask creates a closed system where no mass is lost outside.

What is conservation of mass?

According to the law of conservation of mass, the mass can neither be created nor be destroyed. Thus the total mass of the system is conserved. However similar to the energy, mass can be transformed into energy.

As per this law, the total mass in a chemical reaction is conserved. Where, the total mass in the reactant side is equal to the total mass in the product side.

When the reaction flask is closed with a balloon, the gas if any evolved from the reaction will be collected to the balloon and it inflates. Thus the mass lost from the reaction system does not goes to the surroundings due to the closed system.

Both containers prevent the escape of matter of the reaction into an uncontrolled space, therefore it is a closed system (not isolated, since energy can still go in and out).
