If they had no sunlight the whole food chain would be thrown off the produce would not grow giving the primary consumer nothing to eat then that and if they have no food they won’t survive and if that were to happen then the secondary consumer would have nothing to eat and it goes on and on for the rest of the chain.

What element has 80 protons, 81 neutrons, 79 electrons?

Mariana [72]

Answer:

The element will be $^{161}_{80}X$

Explanation:

Given that,

Number of proton = 80

Number of neutron = 81

Number of electron = 79

We know that,

The atomic number is equal to the number of proton.

So, the atomic number is 80.

According to atomic number,

The element will be mercury.

We need to calculate the atomic mass

Using formula of atomic mass

$atomic\ mass=atomic\ number+number\ of\ neutron$

Put the value into the formula

$atomic\ mass=80+81$

$atomic\ mass=161$

We need to find the element

Using atomic mass and atomic number

$atomic\ mass\ number A=161$

$atomic\ number Z=80$

So, the element will be

$^{A}_{Z}X$

Put the value of A and Z

Hence, The element will be $^{161}_{80}X$

At high temperatures, sulfur combines with iron to form brown-black iron(II) sulfide:

taurus [48]

The percent yield : 79.9%

<h3>Further eplanation </h3>

Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

Fe(s)+S(s)⇒FeS(s)

The reaction produces 6.29 g of iron(II) sulfide⇒an actual yield

The maximum amount that can be produced is 7.87 g ⇒ A theoretical yield

$\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\\%yield=\dfrac{6.29}{7.87}\times 100\5=79.9\%$
