A student uses a magnet to move a 0.25kg metal ball. The magnet exerts a force of 5N on the ball. What is the acceleration of the ball when it begins to move ?
Answers
Answer:
20 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{5}{0.25} \\ [/tex]
We have the final answer as
20 m/s²Hope this helps you

Answer:
Nuestra alimentacion debe estar basada en alimentos ricos en vitaminas, minerales como las frutas verduras, legumbres y semillas.
Explanation:
Los alimentos ultraprocesados son altos en sodio, conservantes, y pobres en vitaminas, es por eso que deben ser evitados ya que algunos hasta se consideran hasta carcinogenos.

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
Answers
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.

Synthetic polymers are biodegradable.
Synthetic polymers are not flexible.
Synthetic polymers are recycled cheaply.
Synthetic polymers are inexpensive to produce.
Answers
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.

Answers
Answer: 3.2x10^23
Explanation:
Start by finding the molar mass of aluminum.
Then turn grams into moles by dividing grams of substance by molar mass. 1.4g÷26.98g
Then multiply that by 6.022x10^23 atoms. 0.0519x6.022x10^23
You can use dimensional analysis to solve this type of problem.

Aluminium and oxygen react to produce aluminium oxide,
4 Al + 3 02 - 2 AL,O
How many kilograms of aluminium oxide are formed when 5,4 kg of aluminium react
with excess oxygen?
A 5,4 kg
B 88 kg
C 10.2 kg
D 33,6 kg
Answers
The balanced reaction is
4 Al + 3 O₂ → 2 Al₂O₃
so that for every 4 moles of Al and 3 moles of O2, you end up with 2 moles of Al₂O₃.
• Al has molar mass ≈ 26.982 g/mol
• O has molar mass ≈ 15.999 g/mol
• Al₂O₃ thus has molar mass ≈ 101.961 g/mol
You start with 5.4 kg = 5,400 g of Al, or
(5.4 kg Al) • (1/26.982 mol/g) ≈ 200.133 mol Al
Al₂O₃ is produced in a ratio of 2 moles to every 4 moles of Al, so you end up with about 100.067 mol Al₂O₃, which has a mass of
(100.067 mol Al₂O₃) • (101.961 g/mol) ≈ 10,202 g = 10.2 kg
so the answer is C.

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.

Is the trend in reactivity for nonmetals the same as the trend in reactivity for metals?
Answers
Period - reactivity increases as you go from the left to the right. Group - reactivity decreases as you go down the group. hope this helps, sorry if it doesn’t
Answer:
no
Explanation:
In Non-metals
Period - reactivity increases as you go from the left to the right. Group - reactivity decreases as you go down the group
In Metals
Reactivity increases down a group because as nuclear shielding increases and the nucleus' hold on the valence electron weakens, therefore it is easier to remove valence electrons.
