HELP ASAP, PLEASE! I also have another question that has yet to be answered (it's a chemistry question) that's worth the same am

ount of points as this one.
Explain how the existence of ions relates to the number of electrons present in atoms of an element?

I forgot this one, but I learned this in physics class. It had something to do with there being more or less electrons for how ever many photons there is in an atom.

Example: Hydrogen has 1 photon which usually means there is one electron, but when there is more electrons than photons, that is a negative ion. When there's less electrons than photons, that is a positive ion.

hope this helps

What data should be plotted to show that experimental concentration data fits a first-order reaction? A) 1/[reactant] vs. time B
natita [175]

Answer:

C) In[reactant] vs. time

Explanation:

For a first order reaction the integrated rate law equation is:

A = A_{0}e^{-kt}

where A(0) = initial concentration of the reactant

A = concentration after time 't'

k = rate constant

Taking ln on both sides gives:

ln[A] = ln[A]_{0}-kt

Therefore a plot of ln[A] vs t should give a straight line with a slope = -k

Hence, ln[reactant] vs time should be plotted for a first order reaction.

How many total moles of reactants and how many total moles of products are in the reaction 2NO, (g) +
zavuch27 [327]

Answer:

moles reactant = 2, moles of products = 3

Explanation:

The reactants are on the left side of the equation. Although, energy (heat) is a reactant it will not factor into the calculation for moles. The coefficient is the number of moles for each substances. So for the reactant side NO would have 2 moles because the coefficient is 2. Using the same logic, NO on the product side will have 2 moles and O2 will be 1 mole. O2 has one mole because it is implied that you know anything multipled by one is the same number. So 1 mole of O2 is written as O2 and not 1 O2.

Hope this helps,

if not just leave a comment!

What needed to be present in marine mud to form fossil fuels?
UkoKoshka [18]
When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Another name for light is
Karo-lina-s [1.5K]

Answer:

Another name for light is ¨Electromagnetic Radiation, luminous energy, and/or radiant energy.¨

Explanation:

Light is the electromagnetic radiation that´s capable of causing a visual sensation and has wavelengths from about 380 to about 780 nanometres. Electromagnetic radiation includes Radio Waves, Microwaves <u>(used in microwaves)</u>, Infrared Radiation <u>(heat)</u>, Visible Light <u>(the colors we see)</u>, Ultraviolet <u>(the UV radiation that causes sunburns)</u>, X-Rays <u>(used in medical X-Rays)</u>, and Gamma Rays <u>(which can be used to treat cancer)</u>. Light waves are transverse waves because they only travel east or west, but their crests and troughs face north and south (if desplayed on a coordinate grid). They wouldn´t be longitudinal waves because these waves don´t have vertical crests and troughs.

I hope this helps!
