Blaire is teaching her little brother to ride his bike. She uses 7 N of force to push a 14 kg bike. What is the acceleration?
98 m/s2
0.5 m/s2
21 m/s2
2 m/s2

Answers

Answer 1

Answer:

The solution is

Explanation:

a = f/m

a =7/14

a=1/2

a=0.5

Answer 2

Acceleration of bike is 0.5 m/s²

Given that:

Force used in push = 7 N

Mass of bike = 14 kg

Find:

Acceleration of bike

Computation:

Force = Mass × Acceleration

Force used in push = Mass of bike × Acceleration of bike

7 = 14 × Acceleration of bike

Acceleration of bike = 7 / 14

Acceleration of bike = 0.5 m/s²

Answers

Answer: C. The university surveys 600 randomly selected students who attend the university. Correct

Explanation:

22.72 is the average atomic weight of sodium.

What are isotopes?

Isotopes are different versions of a specific element.

1st isotopes of 22u = 28%

2nd isotopes of 23u = 72%

The average atomic weight of sodium be=

22 x 28 + 23 x72

=2272/100

=22.72

Hence, 22.72 is the average atomic weight of sodium.

Answers

Answer:

1. 95.7 ppm

2. 6.67 ppm

Explanation:

Podemos pensar la denominación ppm como partes por millón, es un tipo de unidad que define concentración de solutos en una solución.

ppm = μg/g  o si lo queremos ver en volumen, μg/mL

Quiere decir microgramos de soluto en 1 g de solución o mL de solución.

Ej 1.  En primer lugar convertimos los moles de KNO₃ a gramos

0.00071 mol . 101.1 g/mol = 0.071781 g

Si pasamos los gramos a μg → 0.071781 g . 1000000 μg/ 1g = 71781 μg

Dividimos 71781 μg /750 ml = 95.7 ppm

Ej 2. Convertimos los mg a μg → 4 mg . 1000 μg/ 1 mg = 4000 μg

Ahora dividimos: 4000 μg /600 ml = 6.67 ppm

In a molecule of calcium sulfide, calcium has two valence electron bonds, and a sulfur atom has six valence electrons. How many lone pairs of electrons are present in the Lewis structure of calcium sulfide? Also, state why.
A. one
B. two
C. three
D. four
E. none

Answers

There are 2 lone pairs

Further explanation

Given

a molecule of calcium sulfide

two valence electron of Calcium(Ca)

six valence electrons of Sulfur(S)

Required

number of lone pairs of electrons

Solution

Lewis structure shows the form of bonds that occur in the valence electrons of an element or compound

Valence electrons are electrons used in a chemical bond

To achieve stability, the element S needs 2 more electrons which are obtained from 2 electrons from the Ca element,

A lone pair electrons means refers to an unshared pair of electrons(not bonding to the other atoms)

Which statement is true about a reaction represented by a chemical equation that shows energy as a reactant?


A.
It absorbs energy.

B.
It releases energy.

C.
It is a replacement reaction.

D.
It is a combustion reaction.

Answers

A. It absorbs energy.
reactants are located on the left side of the equation, meaning energy among with other reactants were needed to get the reaction going, so it absorbed energy, which is also the endothermic process. The opposite of that would be having energy on the right side with the products which means that the reaction would've released energy which is the exothermic process. Hope this helps!

Could you use filtration on a solution?

Answers

Answer:

No.

Explanation:

This is because a solution is a mixture with two substances that have already dissolved in each other and so there is no residue left. Filtration works such that part of the mixture has smaller particles that can pass through the membrane of the filter paper while the bigger particles get stuck onto the paper as residue. A solution has a uniform size particle throughout and thus filtration does not work for purifying a solution.

25cm3 of a 0.4M sodium hydroxide solution was diluted into 250cm3 of water. What is the molarityof the resultant solution.

Answers

Answer:

0.04 M

Explanation:

From the question given above, the following data were obtained:

Initial volume of solution (V1) = 25 cm³

Initial Molarity of solution (M1) = 0.4 M

Final volume of solution (V2) = 250 cm³

Final Molarity of solution (M2) =?

We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:

M1V1 = M2V2

0.4 × 25 = M2 × 250

10 = M2 × 250

Divide both side by 250

M2 = 10/250

M2 = 0.04 M

Therefore, the resulting molarity of the diluted solution is 0.04 M
