Answer:
x = 1/100 = 0.01
Explanation:
1/10 = √x
(1/10)² = (√x)²
1/100 = x
or x = 0.01

Which statement best describes the role of the nervous system? *
5 points
collects waste produced by cells and removes it from the body
O it breaks down food, absorbs nutrients, and gets rid of solid waste
O
the network of nerve cells and fibers that transmits nerve impulses between parts of
the body
O
brings oxygen into the lungs and releases carbon dioxide and water (waste materials)
from the body.
Answer:
The network of nerve cells and fibres that transmits nerve impulses between parts of the body.
Answer:
THE STATEMENT WHICH BEST FITS THE NERVOUS SYSTEM IS:THE NETWORK OF NERVE CELLS AND FIBRES THE TRANSMITS NERVES IMPULSES BETWEEN PARTS OF THE BODY.What is the mass of a sample containing 3.5 moles of silicon atoms?

a particle moves through gas at a speed of 1.5 km/m. How long will it take for the particle to go a distance of 158 m
Answer:
Particle take 0.11 min to travel 158 m distance.
Explanation:
Given data:
Speed of particle = 1.5 Km/m
Distance to cover = 158 m (158/1000 = 0.158 Km)
Time taken = ?
Solution:
Formula:
s = d/t
s = speed
d = distance
t = time
Now we will put the values in formula.
1.5 Km/m = 0.158 Km / t
t = 0.158 Km /1.5 Km/m
t = 0.11 min
Thus, particle take 0.11 min to travel 158 m distance.
6. The concentration of a solution is : a)The amount of solvent needed to fully dissolve a solute b)The measurement of how large a mixture can get before it becomes a solution c)The measurement of how much solute can be dissolved in a liter of solvent d)The proportion of solute to solvent in a mixture
Answer:
Option c) The measurement of how much solute can be dissolved in a liter of solvent.
Explanation:
The concentration of a solution can be defined as the amount of solute in 1 litre of the solvent i.e how much of the solute that can dissolve in a litre of the solvent. Mathematically, it can be written as:
Concentration = mole of solute / Volume of solvent
Thus, the unit for the concentration is mole per litre (mol/L)
From the above illustration, we thus say that the concentration of a solution is a measure of how much solute can be dissolved in a liter of solvent.
Answer: A) Increase the amount of solute.
C) Decrease the amount of solvent.

Which statement about exothermic reactions is true?
The reaction container always feels cold.
The reactants have more heat energy than the products.
O Energy from an outside source is continuously being added.
More heat is given off than is put into the reaction.
Answer:
The reactants have more heat energy than the products.
Explanation:
The reactants in an exothermic reaction have higher potential heat energy than the products, this is because they release the energy as heat.
Answer:
just took test is the reactants have more heat
Explanation:
1
Which of the following parts of Dalton's Atomic Theory IS supported by
Thomson's and Rutherford's model?
Everything is made of atoms
Electrons are larger than atoms
Atoms are indivisible
Atoms take the form of a solid sphere
Answerfirst one
Explanation:
Why are ions formed?
Answer:
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells.
Explanation:
When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.

Calculate the volume, in liters, occupied by 0.960 mol of oxygen gas at STP.
Answer:
21.504 liters
Explanation:
Given: 0.960 mol
Volume: ?
Molar Volume at STP = 22.4 liters
0.960 mol × 22.4 L/ 1 mol =
0.960 × 22.4 L = 21.504 L
1. What is the density of a strip of magnesium that occupies a volume of 8.49 mL and weighs
33.7 g.
I
Answer:
The answer is 3.97 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of metal = 33.7 g
volume = 8.49 mL
So we have
[tex]density = \frac{33.7}{8.49} \\ = 3.969375736...[/tex]
We have the final answer as
3.97 g/mLHope this helps you
