which best describes how heat energy moves within the system?

Answers

Answer: B

Heat always travels from warmer areas to cooler areas in the form of radiation or convection currents due to the temperature difference. You could kind of think of this movement like diffusion: travelling from a higher concentration to a lower one (if you take biology). This is how a gas heats up a pan on the stove or a radiator warms a room

You can do this perfectly well without referring to chemical shift tables at all. In the spectrum there are a total of three peaks - that means that there are only three different environments for the carbons, despite there being four carbon atoms.

Which two characteristics determine the strength of the gravitational force
between two objects?
A. The distance between the objects' centers
B. The distance between the objects' surfaces
C. The amount of matter in the objects
D. The total volume of the objects

Answers

Answer:

A and C

Explanation:

I took the test

The distance between the objects' centers and The amount of matter in the objects are two characteristics determine the strength of the gravitational force between two objects.

What is Gravitational force?

All objects with mass or energy are attracted to one another by gravity, which is a fundamental interaction.

The electromagnetic force, the weak interaction, and the strong interaction are all significantly stronger than gravity, which is by far the weakest of the four fundamental interactions.

As a result, it has no appreciable impact on subatomic particle level phenomena. However, at the macroscopic level, gravity is the most important interaction between objects and governs the motion of planets, stars, galaxies, and even light.

Therefore, The distance between the objects' centers and The amount of matter in the objects are two characteristics determine the strength of the gravitational force between two objects.

Answer:

x=403/24,3 = 16.58 gm MgO

EXPLANATION

The student burns 10 g of magnesium in air to produce magnesium oxide (MgO)

2Mg + 0 + 2MgO

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.

Oxygen exist in nature as O2, diatomic.

The student burns 10 g of magnesium in air to produce magnesium oxide (MgO).

2Mg + 02 + 2MgO

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.

2 moles of Mg produce 2 moles of MgO

1 mole of Mg weighs 24.3 and produces 1 mole of MgO

Mg HAS AN ATOMIC MASS OF 24.3

Mg HAS A MOLAR MASS OF 24.3 +16 = 40.3gm/mole

so 24.3 gm of Mg produce 40.3 gm MgO

set up the ratio

10 gm Mg/x of MgO = 24.3/40.3

10/x = 24.3/40.3

cross multiply and isolate x (use Algebra I)

24.3x =403

x=403/24,3 = 16.58 gm MgO

A 1.60 g calcium supplement that contains 37.8% Ca by mass, contains 1.51 g of CaCO₃.

We want to calculate the mass of CaCO₃ in a 1.60 g supplement. We need to consider the following relationships.

The mass percent of Ca is 37.8%, that is, there are 37.8 g of Ca every 100 g of supplement.The molar mass of Ca is 40.08 g/mol.The molar ratio of Ca to CaCO₃ is 1:1.The molar mass of CaCO₃ is 100.09 g/mol.

C) N in AgNO₃
D) Ca in CaI₂
E) This is not an oxidation/reduction type of reaction

Answers

Answer:

E) This is not an Oxidation/ Reduction type of reaction

Explanation:

Oxidation involves the loss of electrons while reduction involves the addition of electrons. None of the elements change their oxidation number in the reaction, so this is not an oxidation/reduction type of reaction.

The addition of oxygen and the removal is electrons is called oxidation. In a reaction that has both the process is called the redox reactions.

The correct answer to the question is option E

In this reaction, not any elements have the loose and gain the electrons in order to tell the oxidation and reduction.

This reaction is a neutralization reaction.

Hence, the correct answer is E that is not an oxidation/reduction type of reaction.

what is a nucleus and what are the functions?

Answers

nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane. This membrane seems to be continuous with the endoplasmic reticulum (a membranous network) of the cell and has pores, which probably permit the entrance of large molecules. The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

When he retired I bought not only all his big equipment but all his little toolboxes as well--they were treasures!I decided to put his entire machine shop in our basement, but there were two problems... One, his shop wouldn't fit in our basement, and two, there was no way the lathe, weighing fifteen hundred pounds, and the milling machine, weighing two thousand pounds, could be carried into the basement.
