Answer:

Explanation:

You would have to add up the atomic masses of all the compounds in the compound, making sure you include how many molecules of each are in the compound

For example, in CuSOA we have 1 molecule of Cu and S, as 4 molecules of O

The atomic masses are as follows:

Cu = 63.55 u

S = 32.065 u

O = 15.99 units

This is how we would add it up:

(Atomic mass of Cu) + (Atomic mass of S) + 4(Atomic Mass of O)

(63.55) + (32.065) + 4(15.99)

(63.55) + (32.065) + 63.96

= 159.575 u

What is the difference between pools and fluxes?

Image result for Is industry pool or flux

Fluxes describe the movement of energy and matter between different pools. When you pour a glass of juice for yourself, the juice bottle and the glass are both “pools” for the apple juice. The act of pouring it from the bottle to the glass is the flux

Explanation:

After 160 years, the activity level of the sample will be 0.5 curies.

Half life of any radioactive waste is the half decay of that product.

The formula is [tex]\dfrac{\lambda }{\lambda_1} = 2^\dfrac{a}{b}[/tex]

Where, λ is 4 cruies

λ1 is 0.5 cruies

b = 40 years

Putting the values in the equation

[tex]\dfrac{4}{0.5} = 2^\dfrac{a}{40}\\\\\\\dfrac{a}{40} = 4\\ = 160 years[/tex]

Thus, the correct option is 160 years.

The general effect we see as temperature increases is that rate of dissolution of a solid solute increases,

Therefore, we can say that :

Temperature ∝ Rate of dissolution

Taking into account the scientific notation, the result of the sum is 6.6365×10⁵.

First, remember that scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a×10ⁿ

where:

You want to add two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found.

In this case, the highest exponent is 5.

Then all the values ​​are expressed as a function of the base 10 exponent with the highest exponent. In this case: 8.6500×10³= 0.086500×10⁵

Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:

0.086500×10⁵ + 6.5500×10⁵= (0.086500+ 6.5500)×10⁵=  6.6365×10⁵

Finally, the result of the sum is 6.6365×10⁵.

The alkali metals can't exist alone in nature because of incomplete outermost shell of alkali metals.

The alkali metals have the high thermal and electrical conductivity. It has high lustre, ductility, and malleability as compared to other materials. Each alkali metal atom has one electron in its outermost shell which make more reactive.

So we can conclude that the alkali metals can't exist alone in nature because of incomplete outermost shell of alkali metals.
