FALSE

There are other limiting factors like lack of space, diseases, and com petition.

The correct answer is False

Explanation:

A limiting factor refers to a condition that stops or limits the growth of a population of any species. Some of these factors include the availability of sources such as food, shelter or water; predation; natural weather conditions; natural disasters; and competence.

The previous idea implies food is not the only factor or condition that would stop or limit the growth of a population but there are many other factors that could prevent a population from growing too large, this includes abiotic factors (nonliving condition) such as weather and biotic factors (living condition) such as competition with other species or individuals or predation.

Answer:

Explanation:

1. Force between two charged ions: Electrical force

Electrical force of attraction exists between two charged ions due to constant flow of electrons occuring within their field of influence.

2. Ion made of two or more atoms of different elements : Polyatomic ion

A polyatomic ion is made up of two or more different elements. Most radicals forms polyatomic ion e.g SO₄²⁻

3. Compound whose atoms form bonds by transferring electrons : Ionic compound

Ionic compounds forms by the transfer of electrons from a less electronegativbe atom to a more electronegative one. This is in a bid for the atoms to achieve stability.

4. Smooth solid formed by repeating patterns of ions, atoms, or molecules

: Crystal

A crystal is a unit of an atom which is made up of definite repeating patterns over a long range.

5. Chemical bond formed when electrons are transferred: Ionic bonds

The bonds resulting from the transfer of electrons between two atoms is an ionic bond. An example is that between Na⁺ ions and Cl⁻ ioin in NaCl

Use bond energies to determine Î´hrxn for the reaction between ethanol and hydrogen chloride. ch3ch2oh(g)+hcl(g)âch3ch2cl(g)+h2o

Alex

For this reaction to proceed, the following bond breaking should occur:
*one C-O bond* one H-Cl bond
After, the following bond formations should occur:*one C-Cl bond*one O-H bond
Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.
ΔHrxn = (1)(358) + (1)(431) + 1(-328) + 1(-463) =<em> -2 kJ</em>

For scientific notation, when i move the decimal to the left the the exponent get bigger or smaller?

xeze [42]

I'm not sure what you mean. Besides, I feel like you're talking math.
But anyways, if you have 120 let's say
The scientific notation is 1.20 × 10^2
if you have 125000
the scientific notation is 1.25 × 10^ 5
The number of times you go left the decimal, I guess exponent increases
So yea

Aqueous potassium sulfide and aqueous cobalt (II) chloride are mixed, and a double replacement reaction occurs. What is the corr

alekssr [168]

K2S (aq) + CoCl2( aq) -----> 2KCl (aq) + CoS (s)
potassium + cobalt potassium chloride + carbonyl sulfide
sulfide chloride

carbonyl sulfide :- it is chemical compound with linear formula (OCS ) normally written as (CoS) .it does not show its structure . its is colorless flammable gas with an unpleasant odour.
Potassium chloride :- It is metal halide salt composed of potassium and chlorine. it is odorless and has white or colorless crystal appearance <span />
