Answer:
7
Explanation:
You divide the 14m/s by 2 and get the answer of the acceleration of 7
Answer : The concentration of NaOH is, 0.336 M
Explanation:
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus, the concentration of NaOH is, 0.336 M
The Isotope Notation occur by adding the Superscript showing Mass Number and Subscript showing Atomic Number to the Left of the Element Symbol.
Example,
ᵇₐX
Where;
b = Mass Number
a = Atomic Number
X = Symbol
For Hydrogen Isotopes:
1) Protium: 1 Proton , 0 Neutron
¹₁H
2) Deuterium: 1 Proton , 1 Neutron
²₁H
3) Tritium: 1 Proton , 2 Neutron
³₁H
1. The world without boron would be like a "turtle hiding inside it's shell" Almost everything that we need biologically would not be supplied. There would be plant disorder because of lack of boron that is needed for plants growth. And it would be widespread around the world and causes large of scarcity of food production resulting to chain of reaction to other factors that is part of our daily lives. We are not that high-tech as now and the transition of technology would not be as what we would be expecting in the years to come. We may obtain some of it naturally but it would not be enough later on as the population keeps on growing.
2. Life is still life because we still have other resources we need but it would be quite different as Boron plays a vital role since the earth's formation. As it has many uses in the beginning of civilization as we relies on borates for almost everything. Probably, widespread of plant disorder, poor production of food, rampant of sickness may happen, increasing of pestilence that some of the key ingredient of household products relies on it.
Molarity= (number of moles of that substance) / (Volume of solution in litres)
7= (number of moles of HCl) / 0.05
Thus,
Number of moles of HCl = 7 x 0.05 = 0.35
The number of moles of HCl will remain unchanged.
Now, for new solution,
0.35= 0.35 / (New volume of solution in litres)
Thus,
New volume = 1 litre
Thus, amount of water added = 1- 0.05 litre = 5.0 M
