Could there be non carbon based life?

Lynna [10]

The relationship of radiation with distance obeys the inverse square law. Therefore, doubling the distance decrease the radiation by a factor of 4. The new count is 250.
1) Applying the same principle, the count decreases by a factor of 100. The new count is 10
2) An alpha particle is 4He2 and the Hydrogen can be represented as 1H1
14N7 + 4He2 - 1H1
= 17X8
Proton number 8 belongs to Oxygen. Therefore, the resultant nucleus is:
17O8
3) 185Au79 - 4He2
= 181Ir77
4) X - 4He2 = 234Th90
X = 238U92
5) Beta emission results in the same nucleon number but an increase in the proton number; therefore, the result is:
234Pa91

How is weight affected by gravity

Ira Lisetskai [31]

The higher levels of gravity put on an object the more weight the object has. For example someone who weighs say 100 lbs would weigh more if higher amounts of gravity would be applied to them. And less if less gravity was applied. But larger objects will automatically have more gravity applied to them than something smaller due to the gravitational pull needing to pull harder to keep the object to the planet's surface. Hope this helps! :)

Please solve 13<br> Please

Ymorist [56]

Answer:

1.126 M

Explanation:

From the question given, we obtained the following:

Mass of LiBr = 98g

Volume = 1 L

Molarity of LiBr =?

Next, we'll determine the number of mole of LiBr. This is illustrated below:

Molar Mass of LiBr = 7 + 80 = 87g/mol

Mass of LiBr = 98g

Number of mole = Mass/Molar Mass

Number of mole of LiBr = 98/87

Number of mole of LiBr = 1.126 mole

Now, we can calculate the molarity of LiBr. This is illustrated below:

Molarity is defined as mole per unit litre of the solution. Mathematically, it is represented as:

Molarity = mole /Volume

Mole of LiBr = 1.126 mole

Volume = 1 L

Molarity of LiBr =?

Molarity of LiBr = 1.126 mole /1 L

Molarity of LiBr = 1.126 M

How many milliliters of 0. 0850 m naoh are required to titrate 25. 0 ml of 0. 0720 m hbr to the equivalence point?

charle [14.2K]

The volume of 0.0850 M NaOH is required to titrate 25.0 ml of 0.0720 M is 21.176 ml.

<h3>What are normality and molarity?</h3>

Normality is defined as the number of equivalents per litre of the solution

It is given by

Normality = number of equivalents / 1 L of solution

Molarity is defined as the number of moles of solute present in one litre of solution

Molarity = moles of solute / 1 litre of solution

Relationship between molarity and normality

Normality = Molarity × Acidity or Basicity of a salt

Here, the Acidity Of NaOH is 1 and the basicity of HBr is also 1.

Thus, Normality = Molarity

We know, N₁V₁ = N₂V₂

We can also write it as M₁V₁ = M₂V₂

V1 = $\frac{M_2V_2}{M_!}$

Substitute M₁ = 0.0850 M, M₂ = 0.0720 M, V₂= 25 ml

V1 = 21.176 ml

Hence, The volume of 0. 0850 m NaOH are required to titrate 25. 0 ml of 0. 0720 m is 21.176 ml.
