Which best explains how thermal energy is transferred when someone holds a hand above a fire?
A) It is transferred by conduction and radiation
B) It is transferred by only convection.
C) It is transferred only by conduction
D) It is transferred by convection and radiation.
THE CORRECT ANSWER IS D.
#edge2021
Answer:
D)It is transferred by convection and radiation.
Explanation:
Convection can be regarded as a model of heat transfer involving the transfer of thermal energy via movement of a fluids such liquid or gas. It's a process whereby heat is transferred by movement of a heated fluid. Radiation can be regarded as a model of heat transfer involving the transfer of thermal energy via thermal emission.
Therefore, when someone holds a hand above a fire it heat transfer occur through radiation because it happens through emmision of the heat and also convection as gas.

A.water
B.hydrogen
C.helium
D.oxygen
pls answer will give brainliest
Answer:
A. Water
Explanation:
Virtually every known substance can be referred to as MATTER, as long as it has weight and occupies space. Matter can exists in three different forms namely: solid, liquid and gaseous states.
However, each state of matter has its own unique property that characterizes it. WATER is the only matter that can exists in the three different states as follows:
- LIQUID - WATER
- SOLID - ICE
- GASEOUS - STEAM OR VAPOUR.

You have a 9.51 mol sample of an
unknown element. If the sample has a mass
of 1157.9376 g, what element is this?
Answer:
Antimony
Explanation:
Number of moles = 9.51 mol
Mass= 1157.9376 g
The identity of an element is obtained from it's Molar mass.
This is given by the equation;
Molar mass = Mass / Number of moles
Molar mass = 1157.9376 g / 9.51 mol
Molar mass = 121.76
The only element with molar mass of 121.76 is Antimony
1. EXPLAIN the steps required to find the molar mass of NH3 . Also,
type your final answer to two decimal places.
Answer: Molar mass of [tex]NH_3[/tex] is 17.03 g
Explanation:
Molar mass is defined as the mass in grams of 1 mole of a substance.
S.I Unit of Molar mass is gram per mole and it is represented as g/mol.
It is found by adding the atomic masses of all the elements present.
Atomic Mass of Nitrogen (N) = 14.007 g
Atomic Mass of Hydrogen (H) = 1.008 g
Molar mass of [tex]NH_3[/tex] = 1(14.007)+3(1.008) g = 17.03 g
what substances play an important role in communication between cells in a multicellular organism by acting as a chemical message
Answer:
The correct answer is - ligands such as hormones and neurotransmitters.
Explanation:
Communications between the cells of the unicellular organisms take place by the chemical signaling and the substances that help in sending chemical signals between cells are called ligands.
A ligand is a chemical molecule that binds with a specific molecule or a specific signaling receptor, a protein in or on the target cell. Hormones and neurotransmitters are the ligands that help in cell signaling and send chemical messages to the target sites.

Answer:
2. About 138 g of KI will dissolve in 100 g of water at 10°C
3. 34.5 g of KI will dissolve in 25 g of water
4. The solution is not saturated but is unsaturated
Explanation:
From the graph:
1. KI is more soluble than KCl at 10°C because approximately 138g of KI dissolves at 10°C compared to 30 g of KCl per 100 g of water
2. About 138 g of KI will dissolve in 100 g of water at 10°C
3. 138 g of KI dissolves in 100 g of water at 10°C
In 25 g of water which is 1/4 × 100 g of water, 138/4 g = 34.5 g of KI will dissolve
Therefore, 34.5 g of KI will dissolve in 25 g of water
4.At 20 °C, a saturated solution of NaNO₃ will contain about 88 g of NaNO₃ in 100 g of water.
The solution prepared by the chemist contains 45 g of NaNO₃ in 100 g of water at 20 °C. The amount of solute present in the solution is less thanthe solvent can dissolve at that temperature, therefore, the solution is not saturated.

sugar cannot be separated from sugar solution by filtering explain why?
Answer:
The sugar particles are so small that they have dissolved in the water, and can easily pass through the filter.
Answer:
Sugar can not be separated due it has very fine particles.
Explanation:
When we use to separate sugar with salt they both are dissolved with the water.
What is the difference between a dominant and recessive trait?
Answer: Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. hope this helps
Explanation:
When a dominant trait is present it will always show. For example long tails are dominant. (Ll and LL will both result in long tails). For recessive traits you need two of them for the trait to show. For example short tails are recessive. (You HAVE to get ll for the short tail trait to show in the offspring.
How many atoms are in 0.35 moles of carbon (SHOW WORK)
Answer:
2.108x10²³ atoms
Explanation:
In order to convert from moles (of any substance) to atoms (or molecules), we need to use Avogadro's number: It is the number of units in one mol.
In one mol there are 6.023x10²³ atoms.
0.35 mol * 6.023x10²³ atoms/mol = 2.108x10²³ atoms
Thus, in 0.35 moles of carbon there are 2.108x10²³ atoms.

how does carbon apply to real life
Answer: This is the magic element for everything on Earth. All life on Earth depends on carbon (C). It is in nearly every biological compound that makes up our bodies, systems, organs, cells, and organelles. When you breathe out, there is a lot of carbon dioxide (CO2).
Explanation:
Answer:
Like Carbon dioxide? or just like carbon? well anyway we breath in oxygen and breath out carbon the carbon goes into the air and gets re-cleaned turned into oxygen again. And also thousands of cars that run everyday going places let out tons of carbon into the the air every minute. (aka which is bad for human society, considering there's probably more carbon in the air then there is oxygen.)
Explanation:
So yes carbon does apply in everyday life. By the way the other person is right too. :)

How would you prepare a 1 L solution of 3 M MgO?
Answer:
You need to measure 120.9132 grams of MgO and add to 1 liter of distilled water in a beaker.
Explanation:
Capital M stands for molarity, or moles/liter. So 3 M MgO means 3 moles per liter of MgO.
1 L × [tex]\frac{3 moles MgO}{1 L MgO}[/tex] = 3 moles MgO
This means you need to measure 3 moles MgO to put into 1 Liter of water.
But you don't know how much that is, so you need to convert moles to grams.
First you need to find how many grams are in 1 mole of MgO.
You can search the molar mass of MgO online to get: 40.3044 g
But if you don't have the internet, use the periodic table to add the masses of Mg and O: 24.305 g + 15.999 g = 40.3044 g
Then write the fraction so that the units cancel out, so you get grams by itself on the top of the fraction.
1 L × [tex]\frac{3 moles MgO}{1 L MgO}[/tex] × [tex]\frac{40.3044 g MgO}{1 mole MgO}[/tex] = 120.9132 g MgO
You need to measure 120.9132 grams of MgO and add to 1 liter of distilled water.
We will prepare 1 L solution of 3 M MgO, by dissolving 120.91 grams of MgO in 1 litre of water.
How molarity is define?Molarity is define as the no. of moles of solute dissolve in per liter if solvent or solution & it is represented as:
M = n / v
In the question, it is given that:
Molarity of MgO = 3M i.e. 3 moles of MgO is present in 1 liter of solution.
So, we have moles of MgO = 3 moles
Now, we convert moles of MgO to grams to know how much of solute is required, in the following manner:
n = W / M, where
M = molar mass of MgO = 40.30 g/mole
W = to find?
W = 3 mole × 40.30 g/mole = 120.91 grams
Hence, 120.91 grams of MgO is required.
