98 m/s2
0.5 m/s2
21 m/s2
2 m/s2

Answers

Answer:

The solution is

Explanation:

a = f/m

a =7/14

a=1/2

a=0.5

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

Whic statements explain why rocks weather at different rates? Check all that apply

Answers

Explanation:

Weathering occurs one of three ways: through physical processes such as freezing and thawing, because of live organisms whose roots break rocks or through chemical processes that occur when carbon dioxide in the soil and air and mixes with water and specific minerals in rocks to form a weak acid that reduces rocks into silt, soil and sediment.

Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.

What is the mass of silicon when there are 1.8 x 10^21 atoms of silicon?

Answers

Answer:

Mass = 0.084 g

Explanation:

Given data:

Mass of silicon = ?

Number of atoms of silicon = 1.8 × 10²¹ atom

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³  atoms

1.8 × 10²¹ atom × 1 mole /  6.022 × 10²³  atoms

0.299× 10⁻² mol

0.00299 mol

Mass of silicon:

Mass = number of moles × molar mass

Mass = 0.00299 mol × 28.1 g/mol

Mass = 0.084 g

Please, I really need help. I don't know what to do...

Answers

Answer:

Explanation:

Firstly, let's define what ground and excited state electronic configuration.

Ground state electronic configuration is when the electrons of the atom are in there lowest possible energy level while excited state electronic configuration is when electron(s) have moved to a higher energy level. Examples of these are provided in the options

a. 1s²2s²2p⁴ - This is a ground state electronic configuration (of oxygen) because the electrons are in there lowest possible energy level.

b. This option is not displaying (it is displaying something like an image that isn't loading)

c. 1s²2s²2p³3s¹ - We can see from this that an electron jumped from 2p energy level to 3s (p energy level ought to be completely filled with 6 electrons before another electron moves to the next energy level) meaning the electron is in it's excited state thus this is an excited state electronic configuration (of oxygen).

d. 1s²2s¹2p² - We can see from this also that an electron jumped from the 2s energy level to the 2p energy level (making it 2p² instead of 2p¹ in the ground state). The 2s energy level should ordinarily have 2 electrons. Thus, this is an excited state electronic configuration (of boron).

e. 1s²2s²sp¹ - This is a ground state electronic configuration (of boron) since all the electrons are in there lowest possible energy level.

f. 1s²2s³ - This configuration is impossible because the s energy level should only contain a maximum of 2 electrons, thus impossible to have 3 electrons in the s energy level

Calculate the number of protons and neutrons for ²⁴Mg and 88Sr.

Answers

Answer:

12 protons and 12 neutrons are present in Mg and

38 protons and 50 neutrons are present in Sr

Explanation:

Answer:

For ²⁴Mg

1. Proton number = 12

2. Neutron number = 12

For ⁸⁸Sr:

1. Proton number = 38

2. Neutron number = 50

Explanation:

For ²⁴Mg:

1. Determination of the number of proton.

The atomic number of an element is simply defined as the number protons in the atom of the element. The atomic number of ²⁴Mg is 12 since no two elements have the same atomic number.

Atomic number = 12

Proton number = Atomic number

Proton number = 12

2. Determination of the Neutron number.

Mass number = 24

Proton number = 12

Neutron number =?

Mass number = Proton + Neutron

24 = 12 + Neutron

Collect like terms

Neutron = 24 – 12

Neutron number = 12

For ⁸⁸Sr:

1. Determination of the number of proton.

The atomic number of ⁸⁸Sr is 38.

Atomic number = 38

Proton number = Atomic number

Proton number = 38

2. Determination of the Neutron number.

Mass number = 88

Proton number = 38

Neutron number =?

Mass number = Proton + Neutron

88 = 38 + Neutron

Collect like terms

Neutron = 88 – 38

Neutron number = 50

Order the following elements from Highest to Lowest Electronegativity.

OK, Ca, Sc, Zn, Br
O Br, Zn, Sc, Ca, K

Answers

Answer:

O, Ca, Zn, Br

Sc, K, Br,

Explanation:

The correct order of the chemical elements from highest to lowest electronegativity is: C. Br, Zn, Sc, Ca, K.

Electronegativity refers to a measure of the ability of an atom of a chemical element to attract any shared pair of electrons.

Generally, the electronegativity of a chemical element typically increases across the period from left to right.

In Chemistry, the electronegativity of some of the chemical element are:

Bromine (Br) = 2.96Calcium (Ca) = 1.0Zinc (Zn) = 1.65Potassium (k) = 0.82Scandium (Sc) = 1.36

Hence, the order of the chemical elements from highest to lowest electronegativity is:

1. Bromine (Br) = 2.96

2. Zinc (Zn) = 1.65

3. Scandium (Sc) = 1.36

4. Calcium (Ca) = 1.0

5. Potassium (k) = 0.82

Cobalt (Co) has an atomic mass of 59 and an atomic number of 27. Which statement correctly describes an atom of cobalt?

A. An atom of cobalt contains more neutrons than protons.
B. An atom of cobalt contains more electrons than protons.
C. An atom of cobalt contains the same number of neutrons and protons.
D. An atom of cobalt contains the same number of neutrons, electrons and protons.

Answers

Answer:

A

Explanation:

27 us the number of protons when we subtract 27 from 59 it will be 32 because a mass number is the sum of proton and neutron but tell u more on the comment

Answer: A - An atom of cobalt contains more neutrons than protons.

Explanation: The atomic number is the number of protons in an atom. The atomic mass is the sum of protons & neutrons in an atom. So, with simple math we can figure out the number of neutrons. Total 59 - 27 protons = 32 neutrons. Which means that A is the only right answer in this case.

Little Extra: A & B would both be correct if Cobalt was a negatively charged ion. An atom is an ion if it is charged, and an ion is either negatively charged or positively charged. For example, if Cobalt had 27 protons & 26 electrons it's overall charge would be positive since it has more protons than electrons. And it would be negatively charged if Cobalt had 27 protons & 28 electrons. No charge if there are 27 protons & 27 electrons because proton +1 and electron -1. Imagine 27-27=0 no charge, 27-26= +1 charge, 27-28= -1 charge

A) Neither carbon nor oxygen has satisfied the octet rule

To begin with...

The bond between carbon and oxygen is suppose to have 3 bonds in between

Second:

The lone pairs are not drawn. Since carbon monoxide has 3 bonds in between it should have a lone pair (2 dots) left over on each atom.

Reminder: in order to satisfy the octet rule EACH atom must have 8 electrons. Carbon has 4 valence shell electrons and oxygen has 6. In order to satisfy this rule, there should be 3 bonds in between which makes a total of 6 for each atom plus the lone pairs that make up the 8.
