Answer:

Algebra is an area in mathematics that uses variables, in the forms of letters and symbols, to act as numbers or quantities in equations and formulas. Geometry is an area in mathematics that studies points, lines, varied-dimensional objects and shapes, surfaces, and solids.

Explanation:

It is your own opinion on which is more difficult. In my opinion, Geometry is more difficult.

Answer: I believe they want you to know the variables; and Newton described what? Force, action, mass.

I think you should read the Laws, and see how the variables, those important pieces, are shown in an equation. That will be of real help to you. Get the very basics down in your head (and on paper), and it will be much easier!

The compound sodium carbonate is a strong electrolyte. Write the reaction when solid sodium carbonate is put into water:

Ludmilka [50]

The compound sodium carbonate is a strong electrolyte because it completely dissociates when placed in water into its component ions. The equation of the reaction can be expressed as:

$Na_2CO_3_{(s)} ---> 2 Na^+_{(aq)} + CO_3^{(2+)}_{(aq)}$

The dissociation leads to the formation of sodium and carbonate ions with the latter held together by its internal covalent bond.

This is unlike weak electrolytes that do not dissociate completely in water or aqueous solutions. Only a small fraction of the solute exists as ions in the solution.

The Mohs scale measures A. density of a mineral. B. a mineral’s hardness. C. the luster of a mineral. D. a mineral’s type of cry

disa [49]

B- The Moh's Hardness Scale is 0-10 starting with talc and ending with diamonds that ranks the hardness of minerals. A minerals hardness can be determined by if it scratches another mineral, it is harder, and if it is scratched, it is softer.

1. How much NaCl would you need to weigh out to prepare 100 mL of a 2.5% NaCl<br> solution?

Ira Lisetskai [31]

<h3><u>Answer</u> - 5.85g</h3>

<h3><u>Solution</u> - </h3>

Using the concentration equation, m = CVMo where m is the mass of solute, C is the concentration (M), V is the volume of solution (L) and Mo is molar mass of the solute (g):

Given,

Molar mass of NaCl, M = 58.5g/mol

Volume of the solution, V= 100ml = 0.1L

Molarity, S= 1M

Mass of the solute,W=?

W=SMV

= 1×58.5×0.1

= 5.85g
