Rubidium Rb
when was the element discovered and by whom ??? ASAP MAKE IT AT LEAST A PARAGRAPH!!!
Answer:
Rubidium Rb was discovered in 1861It was discovered by the German chemist Robert Wilhelm Bunsen and the German physicist Gustav-Robert KirchoffExplanation:
Rubidium was discovered by the German chemists Robert Bunsen and Gustav Kirchhoff in 1861 while analyzing samples of the mineral lepidolite with a device called a spectroscope. The sample produced a set of deep red spectral lines they had never seen before. Bunsen was eventually able to isolate samples of rubidium metal. Today, most rubidium is obtained as a byproduct of refining lithium.

What’s the easiest way to add energy to matter
Answer:
The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000

Use the balanced equation from #13 to answer the following:
Calculate how many moles of SO2 can be produced with when given 75 grams of CS2.
Now calculate how many moles of SO2 can be produced with when given 96 grams of O2.
Which one is the limiting reactant (75 grams of CS2 or 96 grams of O2)? How do you know?
Answer:
1. 9600 moles
2. 4096 moles
Explanation:
CS2 + 3 O2=> CO2 + 2 SO2
1. The ratio for CS2: SO2 is :
1:2
If there are 75g of CS2 then there are:
75 × 2= 150g of SO2
Moles = mass × Mr
Moles = 150 × 64
Moles = 9600
2. The ratio for O2 : SO2 is:
3:2
If there are 96g of O2 then there are:
96 × 2/3 = 64g of SO2
moles = mass × Mr
Moles = 64 × 64
Moles = 4096

What happens when a particle and its antiparticle collide? (2 points)
O They combine nuclei
O They break into quarks
They are converted to energy
O They become antimatter
When a particle and its antiparticle collide they are converted to energy.
What is collide?A colloid would be a mixture in which a component made up of insoluble particles that are scattered at a microscopic scale is suspended within another component.
What is energy?In order to accomplish work and to produce heat as well as light, energy must be supplied to a body or even to a physical system. Energy would be the quantitative attribute that does this. Energy would be transformed in form but cannot be created and destroyed, according to the rule of conservation of energy.
Annihilation occurs when a particle collides including its anti-particle. The particle and its antiparticle's whole mass are transformed back into energy to produce two gamma-ray photons. You won't find antiparticles in everyday stuff since they typically barely last for a tiny amount of time until annihilation takes place.
Therefore, the correct answer will be option (c).

Captain uses a steering wheel called him to turn the rudder A sailing ship do you think it would be easier for him to turn a large wheel or a small wheel explain why you think so
Answer:
Large wheel.
Explanation:
It would be easier for the captain to turn a large wheel as compared to a small wheel because less amount of effort is needed by the captain to turn the rudder. If a steering wheel is small, more effort and force is required to turn it while on the other hand, if the steering wheel is large, small effort is needed to turn the rudder. The large size of a sailing boat's steering wheel can help the captain to have more control over the boat as compared to small steering wheel and he is able to access it from either side of the boat.
What is the freezing point, in °C, of a solution made with 1.31 mol of CHCl₃ in 530.0 g of CCl₄?
Answer:
-96.6°C
Explanation:
Given:
moles CHCl3 = 1.31 molmass CCl4 = 530.0 gmass CCl4 = 530.0 g * (1 kg / 1000)
mass CCl4 = 0.5300 kg
First calculate the molality (m) of the solute, which is the moles of solute divided by the kg of solvent ([tex]\frac{moles}{kg}[/tex]):
molality CHCl3 = (mass moles CHCl3) / (mass CCl4 in kg)
molality CHCl3 = (1.31 mol) / (0.5300 kg)
molality CHCl3 = 2.471698m
Decrease in freezing point of solvent = (Kf) * (molality of solute)
Decrease in freezing point of CCl4 = (Kf) * (molality CHCl3)
Decrease in freezing point of CCl4 = (29.8°C/m) * (2.47m)
Decrease in freezing point of CCl4 = 73.6566°C
Then use the molality of the solute to calculate the change in freezing point and subtract the change from the original freezing point.
Freezing point of solution =
(freezing point of pure solvent) - (Decrease in freezing point)
Freezing point of solution = (-22.9°C) - (73.66°C)
Freezing point of solution = -96.6°C

If 0.583 g of ammonia (NH3) is dissolved to make 250 mL of solution, what is the molarity?
Answer:
0.137 M NH3
Explanation:
First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.
0.583 g / 17.031 g/mol = 0.0342 mol NH3
0.0342 mol NH3 / 0.250 L = 0.137 M NH3

A 1.83 mol sample of carbon reacts with excess zinc oxide to produce zinc and carbon dioxide. How many moles of zinc oxide are consumed?
Answer:
3.66 moles of Zinc Oxide are consumed
Explanation:
Based on the reaction:
C + 2ZnO → 2Zn + CO₂
Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.
To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):
1.83 moles C * (2mol ZnO / 1mol C) =

According to kinetic molecular theory, collisions between gas particles in a sample of an ideal gas 1. increase the energy content of the gas sample 2. produce strong attractive forces between the gas particles 3. result in a net loss of energy by the gas sample 4. transfer energy between the gas particles
Answer:
should you prove this or explain or pick the correct answer
According to the kinetic molecular theory, collisions between gas particles in a sample of an ideal gas: Transfer energy between the gas particles. Hence, option 4 is correct.
What is kinetic theory of gases ?According to kinetic theory of gases, when gas particles collide with each other, they transfer energy between themselves. Some collisions will result in the transfer of kinetic energy from one particle to another, while others may result in a transfer of potential energy due to the intermolecular forces between the particles.
However, the total energy of the gas particles is conserved during these collisions, so there is no net loss or gain of energy by the gas sample as a whole.
The kinetic molecular theory also states that ideal gas particles do not have any significant attractive or repulsive forces between them, so option 2 is incorrect.
Additionally, collisions between gas particles do not increase the energy content of the gas sample (option 1) or result in a net loss of energy by the gas sample (option 3).
