Which of the following atoms would have a charge of +1?
An atom with 9 protons, 9 electrons, and 9 neutrons
An atom with 7 protons, 11 electrons, and 8 neutrons
An atom with 5 protons, 5 electrons, and 4 neutrons.
An atom with 6 protons, 5 electrons, and 7 neutrons

Answers

Answer 1

Answer: An atom with 6 protons, 5 electrons, and 7 neutrons

Explanation: In this case, neutrons do not matter as they have a charge of 0, or no charge. A proton has a charge of +1 and an electron has a charge of -1. Since there are 6 protons, the total charge of the protons would be +6. Since there are 5 electrons the total charge of the electrons would be -5. +6 - 5 would result in a charge of +1. This means that this atom would have an overall charge of + 1. Basically, if there is one more proton than electron, then the overall charge of the atom will be +1 but if there is one more electron than proton, then the overall charge of the atom will be -1.

"Henry mixed salt and water together in a cup until he observed a clear solution. He measured the mass of the solution. Then he placed the cup outside for several sunny days during the summer. After a week, he observed that only solid salt remained in the cup and the mass had decreased. Henry concluded that a physical and chemical change occurred in this investigation."

Which statements correctly defend or dispute his conclusion?

A.)He is correct. Dissolving salt in water is a physical change, but evaporating the water is a chemical change. Formation of a solid is evidence that a chemical change occurred.

B.)He is correct. Evaporation is a physical change, but dissolving salt in water is a chemical change. The change in mass is evidence that a chemical change occurred.

C.)He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.

D.)He is incorrect. Dissolving salt in water and evaporation of the water are both chemical changes. The reappearance of salt is evidence that the change was reversible by a chemical change, so it could not be a physical change.

Answer:

C.)He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.

Explanation:

From the analogy of the problem presented, we can see that Henry is grossly incorrect. His conclusion from the process of the experiment he carried out is completely wrong.

Physical changes are changes that alters the physical properties of matter particularly the form and state.

Chemical changes leads to the formation of a new kind of matter.

 We can see that since the salt was obtained back after evaporation, no change has occurred to it.

Therefore, evaporation in itself is a physical change process.

The sun’s core is made of solid rock. True or false

Answers

Answer:

False

Explanation:

Heres what its made of:

The core is made of hot, dense plasma (ions and electrons), at a pressure estimated at 265 billion bar (3.84 trillion psi or 26.5 petapascals (PPa)) at the center. Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center.

Which two elements are the most abundant in the Earth's crust?
OA. iron and magnesium
B. iron and nickel
Oc. silicon and magnesium
OD. silicon and oxygen
Novomatlan
Yes

Answers

Answer:

Look at the properties of Oxygen and Silicon - the two most abundant elements in the Earth's crust - by clicking on their symbols on the Periodic Table.

Explanation:

Answer:

D. silicon and oxygen

Explanation:

The most abundant elements on the earth's crust are silicon and oxygen. Silicon and oxygen forms a wide range of silicate minerals they are found in the crust.

There are many silicates which are derived from the basal units of silicon and oxygen combining together. Other atoms or elements then combines with the silicate framework.

Oxygen is about 46% abundant in the crust whereas silicon takes about 28% to be the second most abundant element on the crust.

Silicate minerals abounds in rocks and within the soil.

Given that nitrogen forms
three bonds with hydrogen to
make NH3, how many hydrogen
atoms do you think will bond
with an atom of phosphorous?

Answers

Answer:

Three

Explanation:

Nitrogen and phosphorus are on the same group in the periodic table. Elements in the same group have similar chemical properties. This is because of the number of valence electrons that they share among each other.

 The valence electrons are the outermost shell electrons found within an atom.

Nitrogen and phosphorus can both be found on the fifth group on the periodic table.

Their oxidation state is:

either 5 or 8-5  = 3

Since phosphorus bonds with 3 hydrogen atoms, nitrogen will also do the same.

Physical and chemical properties are used to describe and identify matter. Physical properties can be observed without changing the identity of the substance.

Large areas on the leaves of some plants lack chlorophyll and are therefore not green in color. How does this most likely affect photosynthesis?

Not enough sunlight is captured in these areas of the leaves.
Carbon dioxide cannot enter these areas of the leaves.
Too much glucose builds up in these areas of the leaves.
Oxygen cannot be released in these areas of the leaves

Answers

Answer:

Not enough sunlight is captured in these areas of the leaves.

Explanation:

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water in the presence of sunlight.

The sunlight is the energy source which drives this chemical change or reaction.

Therefore, to capture the sunlight, the green pigment called chlorophyll is needed. Without this sunlight, photosynthesis will not take place. Photosynthesis is a light dependent reaction. Without light, the process is greatly hampered
