Answer:
1.12 mol/L.
Explanation:
From the question given above, the following data were obtained:
Mole of LiCl = 3.75 moles
Volume = 3.36 L
Molarity =?
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole / Volume
With the above formula, we can obtain the molarity of the solution as follow:
Mole of LiCl = 3.75 moles
Volume = 3.36 L
Molarity =?
Molarity = mole /Volume
Molarity = 3.75 / 3.36
Molarity = 1.12 mol/L
Thus, the molarity of the solution is 1.12 mol/L

What makes the Earth go around the Sun?
Answer:
Just as the Moon orbits the Earth because of the pull of Earth's gravity, the Earth orbits the Sun because of the pull of the Sun's gravity. ... This happens because the Earth has a velocity in the direction perpendicular to the force of the Sun's pull.

Answer all questions please and be quick, it’s very URGENT
U will get BRAINLY
Explanation:
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. ... Electric charge is carried by subatomic particles. In ordinary matter, negativecharge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
How are prisms and raindrops alike?
They are both transparent.
They both reflect white light.
They are both translucent.
They both refract white light.
they both refract white light.
Answer:
They both reflect white light.
Explanation:
How raindrops and prism are similar?
Raindrops and prisms are similar because they both cause light to bend when it enters a prism or raindrop. When light enters a raindrop it causes the light to bend (refract) and separates the white lights into different wavelengths, allowing us to see the individual colors of the rainbow.

What is black powder made of? (Please provide percentage composition of elements as well) Will give brainliest
Answer:
Black powder has 3 main ingredients: Sulfur ([tex]S[/tex]), charcoal ([tex]C_{7}H_{4}O[/tex]), and potassium nitrate ([tex]KNO_{3}[/tex]).
Charcoal is basically just burnt wood and potassium nitrate can easily be displaced.
Keep in mind that this is BLACK POWDER and not actual gunpowder. The difference between the both is significant since gunpowder has a lot more refining processes it has to go through to be actually used in firearms and such.
The percentage composition of black powder should be 75% Potassium Nitrate, 10% Sulfur, and 15% charcoal.
Should be noted that black powder is not a safe compound to deal with, as static friction could ignite it.
There are other alternatives to Black powder such as nitroglycerin (used in dynamites) which is way more powerful and useful in doing mines and exploration but is an extremely tricky and reactive substance to work with.
I do hope this is just for educational purposes because you need to be certified to even just experiment with this (and there are laws to synthesize such as well, which I won't take any responsibility for)
Answer:
sulfur, charcoal and potassium nitrate

if atomic mass of Mg atom is 24g,find the mass of 1 Mg atom
Answer:
4×10^-23g
Explanation:
Given atomic mass of Mg = 24g
To find mass of 1Mg = ?
So its fix that the atomic mass of Mg 24 g is 6.022×10^23
Then the Atomic mass of 1 Mg atom is = 24 ÷ 6.022×10^23
= 4×10^-23 g
Convert 23 grams of nitrogen dioxide into moles of nitrogen dioxide.
Answer:
We have to convert the following into moles.
(a) 32 g of oxygen gas = 1 mole
1 gram of oxygen gas = 1/32 mole
Given that 12 g of oxygen gas
No: of moles = given mass / molar mass
= 12 / 32 = 0.375 mole
(b) 18 g of water = 1 mole
1 gram of water = 1/18 mole
Given that 20 g of water
No: of moles = given mass / molar mass
= 20 / 18 = 1.111 mole
(c) 44 g of carbon dioxide = 1 mole
1 gram of CO2 = 1/44 mole
Given that 22 g of carbon dioxide
No: of moles = given mass / molar mass
= 22 / 44 = 0.5 mole

A compound contains 25.94%N and 74.06% O by mass whats the empirical formula
Answer:
the answer is NO or nitric oxide.
hope this helps, love. have a good day
Explanation:
Empirical formula is the simplest whole number ration of elements in a compound. Molecular formula is n times the empirical formula, where n is integers 1,2,... Therefore, the empirical formula is NO[tex]_2[/tex].
What is Empirical formula?Empirical formula gives the proportion of the element that is present in a compound. It does not give information about the actual number or the arrangements of the atoms.
The relation between molecular formula and empirical formula can be given as
n= molecular formula÷ empirical formula
Number of gram atoms in compound and divide by smallest Number of gram atoms in compound
N=(25.94%)÷14=1.85/1.85=1
O=( 74.06% )÷16=4.62/1.85=2
The atomic ratio is 1:2
Whole number N:O is1:2
Empirical formula corresponding to this whole number is NO[tex]_2[/tex].
Therefore, the empirical formula is NO[tex]_2[/tex].

A Air at a temperature of 134°C and atmospheric pressure flows with a velocity of 7 m/s over
a smooth 5 m long and 1 m wide cast iron plate. Under steady-state conditions, the air-side
surface temperature of the plates is at 120°C. Under the described conditions, determine the
overall heat transfer rate through the plate.

area) and the cylinder's length is the same as the width of the plate (1.0 m), what would be the
heat transfer rate for cross air flow over the outside surface of the cylinder?

Bill sets up an experiment to determine and predict the velocity of a marble at the end of a track. He uses an electronic balance to weigh the marble. He then places the marble at the top of the track and releases it. Artie uses the time it takes the marble to pass through a photogate at the bottom of the track to calculate the velocity of the marble. ill notes that his prediction is significantly higher than his calculated velocity. Which error explains this difference? A) Bill forgot to account for friction. B) Bill forgot to zero the balance and found a weight for the marble that was too low. C) Bill weighed the marble in a weighing dish and failed to account for the mass of the weighing dish. D) Bill didn't position the photogate correctly and got the time required for the top of the marble to pass through, rather than reach the middle.

Diazene, N2H2 (also known as diimine), is commonly used as a reagent for organic syntheses. Label each image with the type of
bond in diazene that it shows.
The first image shown at the left hand side is a pi bond. The other two images show sigma bonds.
In chemistry, a bond results from the overlap of atomic orbitals. This overlap may be end to end (sigma bond) or side by side (pi bond). Having said this, it is easier to decide whether the bonds in the image shown are sigma or bi bonds.
If we label the images; 1,2,3 from left to right, we can see that the overlap in image 1 is side by side. The electron density lies above and below the plane of the bond. This is a pi bond. In images 2 and 3, the overlap occurs in an end to end manner. This is a sigma bond.
