The difference between mass and time is the influence of the earth's gravitational force on objects

<h3><em>Further explanation</em></h3>

In general, some people equate mass and weight.

Mass is one of the principal quantities, which is related to the matter in the matter, whereas weight is a force that leads to the center of the earth which is subject to the earth to matter (Earth's gravitational force)

So that the mass does not depend on the location of the object, while the weight can change depending on the position of the object

In international standards, the mass unit is kg while the weight is in units of newton

1 kg itself is the mass of a cylinder made of platinum-iridium

While the standard mass of an atom is determined according to the carbon-12 atomic mass of 12 atomic mass units

1 atomic mass unit comparable to 1.6605402.10-17 kg

Measuring the atomic mass using a mass spectrometer.

The mass itself can be measured by the arm balance while the weight is measured by the spring balance

One equation that can relate mass and force (weight) is

W = m.g

W = weight, N

m = mass, kg

g = gravity acceleration, m / s2

Actually mass and weight are two different things but most people did not understand the difference between them. And they are used synonymously on the earth. Mass is the measure of the amount of matter and weight is the measure of how the force of gravity acts on the mass that is Weight = mass x force of gravity. And they are also directly proportional to each other that is also the reason both terms are used synonymously.

I HAVE TIME LIMIT I NEED CORRECT ANSWERS!

Basile [38]

Answer:

5) oxygen

7)0.5480 M

9)5s

10) 2 σ and 2 π bonds

12) All of the carbon-oxygen bonds in a carbonate ion are weaker than the carbon-oxygen bonds in a carbon dioxide molecule

19) 0.400 g

Explanation:

For question 5

C2H6 + 7/2 O2 -----> 2CO2 + 3H2O

If 1 mole of ethane gives 2 moles of carbon dioxide

13 moles of ethane will give 13×2 = 26 moles of carbon dioxide

If 3.5 moles of oxygen gives 2 moles of carbon dioxide

42 moles of oxygen will give 42×2/3.5 = 24 moles of carbon dioxide

The reactant that gives the lower number of moles of product is the limiting reactant. This means that oxygen is the limiting reactant here.

7) concentration of acid CA =2.456 M

Concentration of base CB= ???

Volume of acid VA= 15.41 ml

Volume of base VB= 34.53 ml

Number of moles of acid NA= 2

Number of moles of base NB= 1

Ca(OH)2(aq) + 2HCl(aq) ----> CaCl2(aq) + 2H2O (l)

CB= CA VA NB/VB NA

CB= 2.456 × 15.41 ×1/34.53×2

CB= 0.548 M

9) For question 9, we have to look at the electronic configuration of Rb. We have [Kr]5s1. The outermost 5s1 level will have the least effective nuclear charge and is easily lost.

10) There are two sigma bonds and two pi bonds in CO2

12) The C-O bond length in the carbonate ion is 136 pm while the C-O bond length in CO2 is 116 pm. The longer the bond, the weaker the bond hence the C-O bonds in the carbonate ion are weaker than those in the carbon dioxide molecule.

19) From

m= mass of solute

M= molar mass of solute

C= concentration of solute

V= volume of solution

m/M = CV

m= MCV

m= 40.0gmol-1 × 50.0/1000 × 0.200

m= 0.4 g

Calculate the pH of the following:

Brums [2.3K]

The pH can be defined as the negative logarithm of the hydrogen ion concentration of the solution.

What we call the pH can be defined as the negative logarithm of the hydrogen ion concentration of the solution. We are aware that we can use the relation [H+] [OH-] = 1 * 10^-14 to handle the enormity of this problem.

Now, let us go about solving the problems;

1. pH = -log(1 x 10-7) = 7

2. [H+]= 1 * 10^-14/ 1 x 10^-3

pH = -log( 1 * 10^-11)

pH = 11

3. pH = -log( 1 x 10^-2)

pH = 2

4. pH = -log( 1 x 10^-10)

pH = 10

5. [H+]= 1 * 10^-14/ 1 x 10^-8

[H+]= 1 * 10^-6

pH = 6
