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
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

7. Some products or processes claim to be "chemical free" or say "no chemicals added." Based on your understanding of chemistry, what are the arguments for and against such statements?
Please i need help
The meaning behind the statement is that the products does not contains any synthetic and harmful chemicals such as colourants, preservatives etc.
What are synthetic chemicals?All natural products or materials contains certain kind of chemicals which are naturally made in them. Such chemicals are natural chemicals and does not harm the living or causes any unwanted reaction.
The chemicals which are made by humans for specific purposes are called synthetic chemicals. Which can be of toxic and hazardous. Almost all materials we use everyday such as toothpastes, shampoo, food items, dyes, medicines and the fertilizers and pesticides we use in agriculture are all chemicals.
These chemicals helps in some way but they can be harmful to life in other way. Some products claim that they are chemical free, may true or not they intending to clear that the product does not contain any synthetic chemical except the required natural chemicals.

A 1.25 g sample of aluminum is reacted with 3.28 g of copper (II) sulfate. What is the limiting reactant?
2Al(s) + 3CuSO4(aq) = Al2(SO4)3(aq) + 3Cu(s)
Select one:
a. Copper
b. Aluminum sulfate
c. Aluminum
d. Copper (II) sulfate
Answer:
d. Copper (II) sulfate
Explanation:
Given data:
Mass of Al = 1.25 g
Mass of CuSO₄ = 3.28 g
What is limiting reactant = ?
Solution:
Chemical equation:
2Al + 3CuSO₄ → Al₂ (SO₄)₃ + 3Cu
Number of moles of Al:
Number of moles = mass/molar mass
Number of moles = 1.25 g/ 27 g/mol
Number of moles = 0.05 mol
Number of moles of CuSO₄:
Number of moles = mass/molar mass
Number of moles = 3.28 g/ 159.6 g/mol
Number of moles = 0.02 mol
now we will compare the moles of reactant with product.
Al : Al₂ (SO₄)₃
2 : 1
0.05 : 1/2×0.05=0.025 mol
Al : Cu
2 : 3
0.05 : 3/2×0.05 = 0.075 mol
CuSO₄ : Al₂ (SO₄)₃
3 : 1
0.02 : 1/3×0.02=0.007 mol
CuSO₄ : Cu
3 : 3
0.02 : 0.02
Less number of moles of reactants are produced by CuSO₄ thus it will act as limiting reactant.
Where do most earthquakes occur? Where do most volcanoes occur? Why do they occur here?
Answer:
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire
Explanation:
Answer:
Most earthquakes occur along the edge of the oceanic and continental plates. The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking beneath another plate.
Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. As the plates move, they spread apart, collide, or slide past each other. Sixty percent of all active volcanoes occur at the boundaries between tectonic plates.

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.
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

What of these should Hailey include in her list?
Synthetic polymers are biodegradable.
Synthetic polymers are not flexible.
Synthetic polymers are recycled cheaply.
Synthetic polymers are inexpensive to produce.
Answer:
Hailey should add, they are inexpensive to produce.
Explanation:
Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.
Reason being why the others are wrong, synthetic polymers are not biodegradable as they are made in a factory with oils. Synthetic polymers are not flexible due to them being used for harder products. Synthetic polymers are not recycled cheaply as they are made with chemicals which makes it very hard to recycle.

Complete Question:
Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. What does this represent about the type of change happening in the container?
Group of answer choices
A. A chemical change started immediately and finished at eight minutes.
B. A non-chemical change started immediately and finished at eight minutes.
C. A chemical change occurred at four minutes.
D. A non-chemical change occurred at four minutes.
Answer:
A. A chemical change started immediately and finished at eight minutes.
Explanation:
A chemical reaction can be defined as the chemical process which typically involves the reaction between two or more chemical elements (substances) to form a new compound, through the rearrangement of the ionic or molecular structure of each chemical element.
This ultimately implies that, a chemical reaction is a chemical change that immediately starts when two or more molecules of a chemical element (substance) known as reactants are combined together to form a new product (compound).
In this scenario, Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. Thus, what this represent about the type of change happening in the container is that, a chemical change (from red to blue) started immediately and finished at eight minutes.
