Someone please answer

BARSIC [14]

1) 100s of millions of years ago Trees and plants fall into swamps

2) Layers of rotting plant matter builds up underwater

3) Over millions of years the weight of layers heat the plant matter and turn into Peat

4) Over millions of years more pressure and heat turns Peat into coal

How does potassium dihydrogen phosphate affect soil, water, and air

avanturin [10]

Answer:

Potassium dihydrogen phosphate is a potassium salt in which dihydrogen phosphate(1-) is the counterion. ... It is a source of phosphorus and potassium as well as a buffering agent. It can be used in fertilizer mixtures to reduce escape of ammonia by keeping pH low.

What is the molecular formula for a compound that is 44.87% potassium, 36.7%

Phoenix [80]

Answer:

Molecular formula: S4K8O16 empirical formula: SK2O4

Explanation:

First we find the moles of each by first finding grams (using the percent) and then using stoichiometry to convert into moles:

Sulfur: 696 *.18 = 125.28grams S* $\frac{1 mole S}{32.065 g S} = 3.907 moles S$

Potassium: 696 *.4487 = 312.2952 * $\frac{1 mole K}{39.08 g K}$ = 7.99117 mole K

Oxygen: 696 * .367 = 255.432 * $\frac{1 mol O}{16g O}$ = 15.9654 mole O

Then we divide each value by the atom with the smallest number of moles to find the mole ratio:

3.907/3.907= 1

7.99117 mole K/ 3.907= 2.043

15.9654 mole O/ 3.907= 4.08

The empirical formula is SK2O4

To find the molecular formula, we divide the mass given (696) by the mass of the empirical formula (174.22) to get 4. We then divide each atom by 4.

Molecular formula: S4K8O16

Each of the following reactions is incomplete. Match each of the following particles with the correct reaction in order to compl

kiruha [24]

Answer:

1. Option A. Beta decay minus 0 -1e

2. Option B. Alpha 4 2He

3. Option A. Beta decay minus 0 -1e

Explanation:

1. 66 29Cu is undergoing beta decay minus since it produces a daughter nuclei having the same mass number and the atomic number increased by 1 i.e 66 30Zn

2. 238 92U is undergoing alpha decay since the daughter nuclei produced has a decrease of 4 in the mass number and a decrease of 2 in the atomic number ie 234 90Th

3. 14 6C is undergoing beta decay minus since the daughter nuclei produced has the same mass number and the atomic number increased by 1 i.e 14 7N
