ymethyl is CH²OH.MARK BRAINLIEST✌KINDLY FOLLOW ME AND THANK MY ANSWERS❣

it can help you follow meExplanation:Because rate is independent of reactant concentration, a graph of the concentration of any reactant as a function of time is a straight LINE with a SLOPE of [MATH Processing ERROR] . The value of [Math Processing Error] is negative because the concentration of the reactant DECREASES with time.

The three common ISOTOPES of hydrogen are 1H, 2H, and 3H. The PERCENTAGE of each of these FOUND in a SAMPLE is found to be: 1H 99.986%, 2H 0.014%, and 3H 0.0001%.

answerExplanation:A BALLOON when kept in sun bursts after some time because outside the temperature is HIGH and due to that the kinetic energy increases and the MOLECULES of gas PARTICLES inside exerts a pressure on the walls of the balloon so it will CONTINUE to expand and there a stage will come that the balloon will burst.I hope it helps you!pls mark me the brainliest

Naphthalene balls disappear due to sublimation process. In this no solid residue is left and solid is DIRECTLY changed in gaseous state.We can smell the perfume several metres away because of diffusion of gas. because the molecules of perfume DIFFUSE in AIR and air or gas travels here and there.

An anode is an ELECTRODE through which CONVENTIONAL current (positive CHARGE) FLOWS into the device from the external circuit, while a CATHODE is an electrode through which conventional current flows out of the device.

tion:2.84 ng/ul X 5244 ul = 14893 ng = 14.8 UG - correct.Everything you need for all conversions is the formula relating amount (N), volume (V) and concentration (C):C = N / V(concentration is amount per volume) You solved this by N, getting N = C x V, to CALCULATE the TOTAL amount of the solution with given C=2.84ng/ul in a volume of V=5422ul.Your concentration (2.84 ng/ul) is smaller than the MINIMUM concentration required by the centre (5ng/ul). So you will need to concentrate the samples (speed-vac, reduce the volume to less than 50%).Given you want 50ul with a conc of 10ng/ul (twice the minimum required conc), this is how you can proceed:The desired amount is N = C x V = 10ng/ul x 50ul = 500ng.This amount is contained in V = N / C = 500ng / 2.84ng/ul = 176ul of your sample.Take this volume of your sample and concentrated it in a speed-vac to a volumen of less than 50ul.Measure the obtained volume of the concentrated sample (good enough to use a pipet for this purpose) and adjust the volume to 50ul by adding water or buffer.Done. plz thank me

Brass is a HOMOGENEOUS mixture. It's made when COPPER and zinc are mixed. It's CALLED a homogeneous mixture because it LOOKS the same throughout.

This is too broad a question, you can't memorize its oxidation STATES, per se, but you can rationalize what it is by memorizing the rules for common anions it usually bonds with!Explanation:For instance,CuSO4 — copper (II) sulfatex+(+6)+(−8)=0 We know sulfate's charge is 2-, and we also memorize that an oxide anion has an oxidation state of 2-, unless its a peroxide in which case its charge is 1-, but that's another question!So, SOLVING this 8th grade algebra problem, we get:x−2=0 x=2 THUS, in this particular compound, copper's oxidation state is 2+!

When the temperature of a system increases, the KINETIC and POTENTIAL ENERGIES of the atoms and molecules in the system increase. Thus, the internal ENERGY of the system increases, which MEANS that the enthalpy of the system increases – this is true under constant pressure or constant volume.

A COVALENT bond, also CALLED a molecular bond, is a chemical bond that involves the sharing of ELECTRON pairs between atoms. These electron pairs are known as SHARED pairs or bonding pairs, and the stable BALANCE of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

What is an Atom?An atom is the SMALLEST POSSIBLE amount associated with a chemical element. For example, an atom of gold can be called as the smallest quantity of gold you can feasibly have. The word ‘small’ literally points out to nanoscopically tiny! An atom is thousands of times SMALLER than a human hair.Existence of an Atom.It might seem as if there's a simple way to prove atoms exist: put them under the microscope. But this approach won't work. In fact, even the most powerful light-focusing microscopes can't visualise single atoms. ... Atoms are so much smaller than the wavelength of VISIBLE light that the two don't REALLY interact.
