Answers

Answer:

Neutrons have a neutral charge

Explanation:

A neutron consists of 3 quarks, 1 up and 2 down. The up quark has a charge of + 2/3e, and the down quarks each have a charge of - 1/3e. So, the charges on the 3 quarks tend to cancel out to produce a neutrally charged particle.

It is a Neutral charge

A certain type of frog reproduces sexually and has 36 pairs of chromosomes in each of its body cells. How many chromosomes are in each of the frog’s sex cells?

Answers

Answer:

36

Explanation:

Sex cells are different from body cells. Sex cells are made up of haploid number of cells. A haploid cell is half the original number of cell. When sex cell combines, they fuse and unite the half number of cells to form a single diploid which makes a complete body cell by a series of process.
All sex cells only contains half the number of cells in their parent.

Answers

Answer:

D

Explanation:

as an endothermic process because the dough absorbs heat

The baking of a pizza be categorized as an endothermic process because the dough absorbs heat.

What is an Endothermic reaction?

This is the type pf reaction in which heat is absorbed from the surroundings  in a reaction.

During baking, the oven which is the surrounding is usually hot which brings about the dough absorbing the heat. This depicts an  endothermic process and makes option D the most appropriate choice.

Answers

Answer:

7.2 meters per hour

Explanation:

It is given that,

The speed of a paramecium is 2,000 micrometers per second.

We need to find the speed of the paramecium in meters per hour.

We know that,

[tex]1\ \mu m=10^{-6}\ m[/tex]

and

1 hour = 3600 seconds

[tex]v=2000\ \dfrac{\mu m}{s}\\\\=2000\times \dfrac{10^{-6}\ m}{(\dfrac{1}{3600})\ s}\\\\=7.2\ \text{meters/hour}[/tex]

Hence, the speed of the paramecium is 7.2 meters per hour.


Which characteristic best explains why gases are more compressible than liquids or solids?
A Gas particles tend to attract one other, while liquid and solid particles tend to repel each other.
B. Gas particles tend to be separated by larger distances than liquid or solid particles are.
C Gas particles tend to move more rapidly than liquid or solid particles do.
D. Gas particles tend to clump together as their temperatures increase

Answers

Answer:B

Explanation:

Answer:This chapter begins the first where we will look at matter on a microscopic scale.  Matter is made of small particles of atoms or molecules.  There are three common states of matter, solid, liquid and gas.  A gas and a liquid will change shape to fit the shape of their container.  A gas will change volume to fit the volume of the container.

Explanation:

In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them. The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances between them.

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other.   Their vibration is related to their kinetic energy.  In the solid the particles vibrate in place.

Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.

Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other.  In most cases, there are essentially no attractive forces between particles.  This means that a gas has nothing to hold a specific shape or volume.

(A fourth state of matter, called plasma, exists when a gas becomes ionized. Plasma exists inside stars and in interstellar gases.)

A vial is filled with room temperature water, and blue cold water has been placed at the bottom. A warm water bag sits next to the vial. What do you think will happen?

Answers

Explanation:

In the context, a vial which is used in store medical samples is filled with water at room temperature. And the vial is kept on a cold water. Also a water bag containing warm water is kept near the vial.

The cold water kept at the bottom of the vial is having lower kinetic energy while warm water will have higher kinetic energy than the others. Since the water in the vial is at room temperature and it is in touch with the cold blue water, the water in the vial will loose or give its temperature to the cold blue water through conduction as well as convection process since temperature always flows from a hot body towards the cold body.

On the other hand, the warm water placed next tot he vial will give its temperature to the atmosphere.  

A Potassium isotope contains 19 protons, 19 electrons and 21 neutrons. What is its mass number? 40​

Answers

Answer:

17

Explanation:

you add 19+19 the subtract 21. I think

A  potassium isotope contains 19 protons, 19 electrons, and 21 neutrons, so the mass number is 40 as the mass number of the atom is the sum of the protons and the neutrons, the mass number is 40.

What is the significance of the mass number in the atom?

The mass number is significant as it is the sum of the number of protons and neutrons present in nucleus of an atom, which determines the atomic weight of an element and also determines its chemical properties and its position on the periodic table. Isotopes of an element have the same atomic number but a different mass number, so they have different properties than the original element.

Hence, a potassium isotope contains 19 protons, 19 electrons, and 21 neutrons, so the mass number is 40 as the mass number of the atom is the sum of the protons and the neutrons, the mass number is 40.

Terry bought a gold necklace at a pawnshop and was wondering if it was “real” gold. She decided to perform a density test. She placed the necklace in a graduated cylinder of water that had 47.00 mL of water and the water rose to 48.35 mL. She then weighed the necklace and found it to have a mass of 22.89 g. What is the density of Terry’s necklace?

Answers

Answer:

d = 16.96 g/mL

Explanation:

Given that,

Initial water level in graduated cylinder is 47 mL and final water level is 48.35 mL.

The weight of the neclace is 22.89 g.\

We need to find the volume of the necklace. We know that, density equals mass per unit volume. So,

[tex]d=\dfrac{m}{V_f-V_i}\\\\d=\dfrac{22.89\ g}{(48.35-47)\ mL}\\\\d=16.96\ g/mL[/tex]'

Hence, the density of Terry’s necklace is 16.96 g/mL.
