The volume of an object is 55mL in this city is 30g/mL. what is its mass

Answers

Answer 1

Answer:

Mass = 1650g

Explanation:

30g per mL is the density I suppose...

Solve for m!

30g/mL = m/55mL

Multiply by denominator to get numerator!

30* 55 =1650g

m = 1650g

Resistive Frictional Force = 4 N

As we know that frictional forces always act in the opposite of the relative motion [force], and that opposite forces always subtract.

Hence,

The Net Force acting on the block = 10 N -4 N = 6 Newtons

How many liters of ammonia are formed with 49.8 g of nitrogen gas reacting with 10.7 g of hydrogen gas at S.T.P.?

Answers

the reaction is as follows:

N2+3H2---->2NH3

the number of moles of N2 is 49.8g/14gmol^-1=3.56mol

the number of moles of H2 is 10.7g/2gmol^-1=5.35mol

here, since the ratio of N2/H2 is 1/3, we can see that H2 is the limiting reagent. therefore, the reaction proceeds as follows:

N2 + 3H2 ---------------> 2NH3
5.36mol (2/3)(5.36mol)=3.57mol

therefore, the number of moles of ammonia formed is 3.57mol. at STP, P=1atm, T=273K.
Therefore, V(NH3)=(3.57)(22.38)=79.822 L

The force of attraction between one polar molecule and another polar molecule is​

Answers

Answer:

Dipole-dipole forces

Explanation:

A polar compound is that compound which contains atoms that have a difference in charges i.e electrostatic attraction occurs between its constituent atoms. Polar molecules are attracted to other polar molecules with opposite charges and her held together with the aid of certain forces

The attractive force between the negative part of a polar molecule (-) and the positive part of another polar molecule (+) is called DIPOLE-DIPOLE FORCES. This dipole-dipole force gets stronger with an increasing polarity of the molecules involved.

Answer:

C. they carry energy

Explanation:

Energy can be carried from one place to another by waves, including water, light, and sound waves. Waves are oscillating disturbances that travel through but do not move matter.

Infrared radiation escaping from hot coals is an example of invisible waves carrying energy. This energy can be felt as heat.

Answers

Answer:

ions

Explanation:

Individual atoms of the same element but having slightly different number of protons and electrons are called ions.

Ion is a charged particle.

An atom is made up of three fundamental subatomic particles. Protons are the positively charged particles Electrons are the negatively charged particles Neutrons do not carry any charges.

When the number of protons > electrons the body is positively charged.

When the number of electrons > protons the body is negatively charged.

Charged particles are called ions.

At 303 K, the volume of a gas is 30.0 ml. At constant pressure, what is the new
volume of the gas if the temperature is decreased to 283K?

Answers

Answer:

V₂ = 28 mL

Explanation:

Given data:

Initial temperature = 303 K

Initial volume = 30.0 mL

Final temperature = 283 K

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 30.0 mL × 283 K /303 K

V₂ = 8490 mL.K / 303 K

V₂ = 28 mL

How many moles are there in a 122 gram sample of nickel (Ni)?
7.16 x 103 moles
6.22 mol
2.08 mol
0.481 mol

Answers

the molecular weight of nickel is 58.69 g/mol. thus in a 122 gram sample of nickel there are 122/58.69=2.08 moles of nickel.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

Nickel:

The atomic number of nickel is 28.The symbol of nickel is Ni.Density of a nickel 8.908 g/cm3.It is a d block element.It belongs to group 10 and period 4.It is also called transition metal.It is a metal and is located between groups 2 and 3.

Mass of nickel given: 122 grams.

Atomic mass of nickel: 58.71 g mol

Number of moles = Mass / molar mass

                             = 122/ 58.71

                              = 2.078

                              = 2.08 moles.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.
