Which question would most likely be studied by a physicist?A. Were there ever any living organisms on Mars?
B. How can the forces on a space probe be controlled so it will land
on Mars?
O C. What type of substances make up the soil on Mars?
O D. Should the government spend taxpayers' money to send space
probes to Mars?

Answers

Answer 1

Answer:

Answer:A

Explanation: Were there any living organisms is the answer because physics is the study of matter,its motion and behaviour of space and time and some other topics like energy and force.

Answer 2

Answer:

Answer:

Explanation:

Forces and vectors on a probe are a physics thing

How do you convert ethane to ethanoic acid? (with equation please).

Answers

Answer :

There are three processes involved in the conversion of ethane to ethanoic acid.

In first process, on the chlorination of the ethane in the presence of the sunlight or in the presence of U.V light, ethane converted into ethyl chloride.

In the second process, ethyl chloride react with the aqueous potassium hydroxide to give ethanol.

In the third process, ethanol react with an oxidizing agent (Alkaline potassium permanganate) to give ethanoic acid.

The reaction are shown below.

Ethane can be turned into its carboxylic acid form called the ethanoic acid by a series of steps. First chlirinate it in the presence of light. Then, add potassium hydroxide to get an alcohol. Finally, adding KMnO4 to oxidize it to a carboxylic acid. The equations are as follows:
C2H6 + Cl2 ---> C2H5Cl + HCl
C2H5Cl+KOH-> C2H5OH+ KCl.
C2H5OH ----KMnO4 ---> CH3COOH.

Very Important!! Electron lender or borrower?i need to know if these elements lend or borrow electrons and how many do they lend or borrow.
-sodium
-phosphorus
-potassium
-oxygen
-iodine
-cesium
-bromine
-sulfur
-magnesium
Please answer!! Its really important..

Answers

Answer : Lending makes the element as cation (positively charged species) and borrowing makes the element as anion (negatively charged species).

Usually all the metal species donates the electrons and non-metals accepts (borrows) the electrons.

Sodium (Na) donates 1 electron and becomes $Na^(+)$ .

Phosphorus (P) accepts 3 electrons and becomes an anion of phosphorus $P^(-3)$ .

Potassium (K) donates its one electron and gets converted to $K^(+)$ .

Oxygen (O) accepts 2 electrons and turns as $O^(-2)$ .

Iodine (I) accepts one electron and gets converted into $I^(-)$ .

Cesium (Cs) donates 1 electron and turns to $Cs^(+)$ .

Bromine (Br) accepts 1 electron and turns as $Br^(-)$ .

Sulfur (S) accepts 2 electrons and becomes $S^(-2)$ .

Magnesium (Mg) donates its 2 electrons and gets converted as $Mn^(+2)$ .

Sodium lends 1 electron.
Phosphorus borrows 3 electrons.
Potassium lends one electron.
Oxygen borrows 2 electrons.
Iodine borrows one electron.
Cesium lends 1 electron.
Bromine borrows 1 electron.
Sulfur borrows 2 electrons.
And magnesium lends 2 electrons.

Which subatomic particle(s) are found in the nucleus of the atom?. Enter the subatomic particle or particles separated by commas.

Answers

The subatomic particles found in the nucleus of the atom are:

Protons, Neutrons

The subatomic particles found inside the nucleons of the atoms are also referred to as the "nucleons". The nucleons are the protons, which are positively charged, and neutrons, which are neutral. The negatively charged subatomic particles, electrons, are found outside the nucleus.

A 250-mL aqueous solution contains 1.56 mc025-1.jpg 10–5 g of methanol and has a density of 1.03 g/mL. What is the concentration in ppm?A 6.1 X 10^-8 ppm
B 1.5 X 1-^-5 ppm
C 0.061 ppm
D 15 ppm

Answers

The right answer for the question that is being asked and shown above is that: "B 1.5 X 1-^-5 ppm." A 250-mL aqueous solution contains 1.56 mc025-1.jpg 10–5 g of methanol and has a density of 1.03 g/mL. The concentration in ppm is that 1.5 X 1-^-5 ppm

Answer: The correct option is C.

Explanation: ppm is used to measure the concentration of solute in a given volume of solution. ppm is basically parts per million.

Mathematically,

$ppm=\frac{\text{Mass of solute (in mg)}}{\text{Volume of solution (in L)}}$

We are given:

Mass of methanol = $1.56* 10^(-5)g=1.56* 10^(-2)mg$ (Conversion Factor : 1g = 1000mg)

Volume of solution = 250 mL = 0.250L (Conversion Factor : 1L = 1000mL)

Putting values in above equation, we get:

$ppm=(1.56* 10^(-2)mg)/(0.250L)$

Concentration of methanol = 0.062ppm

Hence, the correct option is C.

How does the number of atoms in one mole of argon compare with the number of molecules in one mole of ammonia

Answers

The number of atoms in one molecule of argon is the same as the number of molecules in onemole of Ammonia which is equal to 6.02 × 10²³units.

The Avogadro's number, postulated by italiàn scientist Amedeo Avogadro, is simply defined as the number of units in one mole of any substance (which is defined as the molecular weight in grams), equal to 6.02 × 10²³.

The units may however be electrons, atoms, ions, or molecules, depending on the nature of the substance in discuss.

In this scenario, the number of atoms in onemole of argon is therefore the same as the number of molecules in one mole of Ammonia.

They are the same because the definition of a mole is 6.022 x 10^23 molecules or atoms based on whether it is a molecule or element. so there are 6.022 x 10^23 atoms of argon in one mole of argon and 6.022 x 10^23 molecules of ammonia in one mole of ammonia
